Cladding testing in London
Cladding repair in London involves the technical assessment, maintenance, and remediation of building envelopes to ensure structural integrity, weather resistance, and fire safety compliance. In a city characterized by high-density residential towers and complex commercial facades, these repairs address issues ranging from localized impact damage and sealant failure to systemic installation defects. Unlike full replacement, professional cladding repair focuses on targeted interventions that restore the performance of the external wall system while minimizing disruption to occupants.
For building owners and managing agents, the process begins with identifying specific vulnerabilities within the facade. In London’s unique climate and urban environment, cladding systems are subjected to significant thermal movement, wind loading, and atmospheric pollutants. Effective repair strategies require a deep understanding of how different materials—such as Aluminium Composite Material (ACM), High-Pressure Laminate (HPL), or rainscreen masonry—interact with the building’s primary structure and cavity barriers.
London’s skyline is a mix of heritage masonry, post-war concrete, and modern glass and metal facades. Each of these systems ages differently. Cladding repair in London is rarely a one-size-fits-all service. It is a technical discipline that bridges the gap between routine maintenance and major capital works. When a managing agent notices a loose panel or water staining, the immediate goal is to stabilize the situation and prevent further deterioration.
The complexity of London’s built environment means that access is often the primary challenge. Whether it is a luxury development in Canary Wharf or a social housing block in Southwark, the logistics of reaching the facade safely dictate the repair methodology. We prioritize solutions that address the specific failure point—be it a corroded bracket, a perished gasket, or a cracked terracotta tile—while ensuring the overall weather envelope remains intact.
Most repair projects are triggered by one of three factors: environmental wear, accidental damage, or the discovery of latent defects. In London, the high concentration of tall buildings creates "wind tunnel" effects that can stress fixing points over time. Furthermore, the city's history of rapid development has occasionally left a legacy of sub-standard installations that only become apparent years later through leaks or shifting panels.
Latent defects often involve the internal components of the wall, such as missing fire breaks or incorrectly installed insulation. While the surface might look acceptable, these hidden issues necessitate a more invasive form of repair. We distinguish between "cosmetic" repairs, which focus on the visual aspect of the building, and "performance" repairs, which restore the building’s safety and thermal attributes.
Before any tools are picked up, a rigorous period of cladding testing in London is essential. You cannot fix what you do not fully understand. Testing serves as the diagnostic phase, using both non-destructive and invasive methods to map out the health of the facade. This is particularly important when dealing with older rainscreen systems where the original "as-built" drawings may no longer be accurate or available.
Testing typically involves "opening up" works, where small sections of the cladding are removed to inspect the cavity. We look for evidence of moisture, the condition of the Helping Hand brackets, and the presence of compliant fire-stopping materials. This data-driven approach prevents building owners from overspending on unnecessary replacements or, conversely, underspending on superficial repairs that fail to address underlying safety risks.
By conducting thorough testing, we provide clients with a clear evidence base. This evidence is vital for insurance purposes and for satisfying the requirements of the Building Safety Regulator. In many cases, testing reveals that a building is structurally sound but requires targeted cladding replacement in London for specific non-compliant components, rather than a full-scale recladding project.
A frequent question from property managers is whether a building needs a repair or a full replacement. The answer depends on the systemic nature of the problem. If a building has experienced localized impact damage—perhaps from a window cleaning cradle or extreme weather—a targeted repair is usually sufficient. We source matching panels and fixings to restore the facade to its original condition.
However, cladding replacement in London becomes necessary when the materials themselves are fundamentally flawed. This is most common in cases involving combustible ACM or HPL panels that do not meet current fire safety standards. In these scenarios, repairing the fixings is pointless if the panels themselves pose a risk. Replacement involves a strategic strip-back of the facade and the installation of modern, non-combustible alternatives like solid aluminum or stone wool systems.
Repair is the preferred route when the primary weather barrier and fire safety systems are intact. Typical repair scenarios include:
Replacement is often the only viable path when:
London presents a unique set of challenges for cladding contractors. The density of the city means that many buildings are "landlocked," with limited space for traditional scaffolding. Furthermore, many of these buildings are occupied residential blocks where the comfort and safety of tenants are paramount. Cladding repair in London requires a sophisticated approach to site logistics.
One major challenge is the "interface" between different building elements. A cladding system does not exist in isolation; it interacts with windows, balconies, rooflines, and lightning protection systems. A repair that fixes a panel but compromises a window seal is a failure. Our technical teams focus heavily on these interface details to ensure that the repaired section performs seamlessly with the rest of the building envelope.
In occupied high-rise buildings, repairs must be sequenced to minimize noise and loss of light. We often utilize rope access (abseiling) for minor repairs because it eliminates the need for intrusive scaffolding that can block views and compromise security for months. For larger remediation works, we use mast climbing work platforms (MCWPs), which provide a stable working base but can be lowered when not in use, reducing the "caged-in" feeling for residents.
London boroughs have strict requirements regarding the aesthetic appearance of buildings. Even a repair must often be approved if it involves a change in material or color. We work closely with local planning authorities to ensure that replacement panels match the original design intent, maintaining the architectural heritage of the area while upgrading the building's performance.
To ensure a successful outcome, we follow a structured project lifecycle. This ensures that every cladding repair in London is handled with the necessary technical oversight and quality control. By following a clear path, we help managing agents navigate what can often be a daunting and expensive process.
We begin by reviewing all available O&M (Operating and Maintenance) manuals and previous survey reports. A high-level visual survey is then conducted to identify obvious signs of distress, such as panel deflection, staining, or failing sealants. This phase helps define the scope for more intensive testing.
Using the findings from Phase 1, we conduct targeted "break-outs." This involves removing specific panels to inspect the cavity, insulation, and fire barriers. During this stage, cladding testing is performed to verify the material composition and structural health of the substrate. The result is a comprehensive report outlining the exact state of the facade.
Once the problems are identified, our technical team develops a repair or replacement specification. This includes choosing compatible materials, designing fixing details, and ensuring the fire strategy is robust. For London projects, this often involves coordination with fire engineers to ensure the proposed repairs meet the "Golden Thread" of information required by new safety legislation.
The repair work is carried out by specialist technicians. Whether it is replacing EPDM membranes, installing new cavity barriers, or swapping out damaged rainscreen panels, every step is documented. Quality tallies are kept to ensure that what was designed is actually installed on the wall.
Upon completion, we provide a full record of the works. For many London residential buildings, this concludes with the issuance of an updated EWS1 form or a building safety certificate, which is essential for residents looking to sell or remortgage their properties.
Cladding testing in London
The choice of materials is the most critical factor in the longevity of a repair. In London, the environment is surprisingly harsh; salt air from the Thames and pollutants from heavy traffic can accelerate the corrosion of inferior metals and the degradation of sealants. We emphasize the use of high-specification components that exceed minimum standards.
Aluminium Rainscreen: Often used in modern London developments. Repairs usually involve addressing "oil-canning" (buckling) or replacing damaged powder coating.
Terracotta and Ceramic: Common in high-end residential blocks. These are brittle and prone to impact damage, requiring specialized fixing clips.
Brick Slip Systems: Used to give a traditional look to modular buildings. Repairs often focus on the adhesive bond and the integrity of the mechanical rail system.
Stone Facades: Found in prestigious commercial areas like Mayfair or the City. Repairs involve "pinning" loose slabs and specialist stone cleaning.
Perhaps the most vital part of any modern cladding repair is the hidden fire-stopping. In many older London buildings, fire barriers were either omitted or installed incorrectly. During any repair, we take the opportunity to verify and, if necessary, reinstate intumescent strips and mineral wool barriers. These components are designed to expand in the event of a fire, closing the cavity and preventing the "chimney effect" that allows flames to spread rapidly up a building.
Budgeting for cladding repair in London is a significant concern for housing associations and private freeholders. Costs are influenced by three main variables: the height of the building, the complexity of the access, and the availability of replacement materials. Because London has so many bespoke architectural designs, finding matching panels for a 15-year-old building can sometimes require custom fabrication.
We advocate for a "preventative repair" model. Small investments in localized repairs and regular inspections can significantly extend the life of a facade, delaying the need for a multi-million-pound recladding project. By addressing minor leaks or loose fixings early, building owners avoid the massive secondary costs associated with internal water damage and structural rot.
In the context of facade works, value engineering should never mean cutting corners on safety. Instead, it means finding more efficient ways to achieve the same high-standard result. For example, by combining cladding testing in London with routine window cleaning schedules, we can reduce the cost of access equipment. Our goal is to provide a solution that is commercially viable for the client while remaining technically beyond reproach.
Working on the exterior of a high-rise building in a busy city like London carries inherent risks. These include the risk of falling objects, structural instability during the "strip-back" phase, and the ever-present challenge of fire safety while the building’s protective skin is removed. A professional cladding firm must have robust Risk Assessments and Method Statements (RAMS) in place.
We employ dedicated site supervisors to oversee every project. This is not just about safety; it is about quality assurance. In London’s tight labor market, ensuring that every technician follows the exact installation guide for a specific cladding system is the only way to guarantee a long-term fix. We also manage the "Third Party" risks, ensuring that pedestrians on the London streets below are protected by appropriate hoarding and fans.
Any discussion of cladding repair in London must acknowledge the impact of the Building Safety Act 2022. This legislation has fundamentally changed how high-rise buildings (over 18 meters or 7 stories) are managed. The Act introduces the role of the Principal Accountable Person, who has a legal duty to manage building safety risks.
For repairs, this means that every intervention must be recorded as part of the "Golden Thread." You can no longer simply "patch up" a facade. You must prove that the repair does not degrade the building's fire performance and that the materials used are fully traceable. We assist our London clients by providing the digital documentation needed to satisfy these rigorous new standards.
The External Wall System (EWS1) survey remains a pivot point for the London property market. If a building receives a B2 rating (meaning repairs are needed), the mortgageability of the flats drops instantly. Our repair services are specifically designed to move a building from a B2 to a B1 or A1 rating, restoring the value of the asset and giving peace of mind to the leaseholders.
Modern cladding repair in London also looks at the environmental impact of the building. Facades are the primary layer of thermal insulation. A failing cladding system with gaps or wet insulation significantly increases a building's carbon footprint and energy costs. By repairing thermal bridges and replacing degraded mineral wool, we help London buildings meet the UK’s Net Zero targets.
We also focus on the circular economy. Where possible, we look to repair panels rather than scrap them. If cladding replacement in London is the only option, we ensure that the old materials—especially aluminum and steel—are recycled. Sustainability in construction is no longer an "extra"; it is a core requirement for responsible property management in the capital.
Selecting a contractor for cladding works should be based on technical competency rather than the lowest bid. The risks of poor workmanship are too high. A reputable specialist will have a deep portfolio of high-rise projects and a clear understanding of the specific London boroughs they operate in. They should be able to explain the "why" behind a repair strategy, not just the "how much."
At CladdingTesting.com, we pride ourselves on being the first point of contact for complex facade problems. We don't just sell a service; we provide a pathway to a safe, compliant building. Whether you are dealing with a single leaking panel or a massive remediation requirement, our team provides the technical clarity needed to make informed decisions.
Costs vary significantly based on the height of the building and the type of system. Localized repairs using rope access can start at a few thousand pounds, whereas major remediation projects on high-rise blocks can run into hundreds of thousands. A detailed survey is always required to provide an accurate estimate.
Yes, the majority of our cladding repair in London projects are carried out on occupied buildings. We use specific access methods like mast climbers or abseiling to minimize the impact on residents’ privacy and daily lives. We also provide clear communication plans to keep tenants informed of the work schedule.
If the repair was necessitated by fire safety concerns, an updated EWS1 survey is usually required to confirm that the building now meets the necessary safety standards. This is critical for the sale or refinancing of residential apartments within the block.
Cladding repair focuses on fixing specific issues, such as replacing a few damaged panels or fixing a leak. Recladding, or cladding replacement in London, involves removing the entire existing facade system down to the structural frame and installing a completely new, modern system.
Minor repairs can be completed in a matter of days. However, complex remediation projects involving testing, design, and procurement of matching materials can take several months. The logistical challenges of working in London—such as obtaining permits—also influence the timeline.
This depends on the cause of the damage. If the repair is due to a sudden event like a storm, it may be covered by buildings insurance. If it is due to a latent defect or poor original construction, you may need to pursue the original developer or use government funds like the Building Safety Fund.
If you notice signs of water ingress, visible damage, loose panels, or if your building lacks a current fire safety certificate, you should arrange for cladding testing in London. It is always better to identify issues early through a professional audit than to wait for a major failure.
While we can source or fabricate most panels, some older systems have been discontinued. In these cases, we work with manufacturers to find the closest possible match in terms of both aesthetics and performance, ensuring the repair does not look out of place.
The primary regulations are the Building Regulations (Approved Document B for fire, Document L for thermal), the Building Safety Act 2022, and the Fire Safety Act 2021. All our work is designed to comply with these statutory requirements.
London’s challenges include high wind loads on tall buildings, strict council regulations, limited space for equipment, and the high density of occupied residential units. Navigating these factors requires a contractor with specific experience in the London urban environment.
When you are responsible for a building with cladding issues, the path forward can seem complex. Between changing regulations and the technical demands of facade engineering, it is easy to feel overwhelmed. Our role is to provide the expert guidance and practical execution needed to ensure your building remains a safe, valuable, and high-performing asset for years to come.

For building owners and property managers across the United Kingdom, cladding replacement has shifted from an aesthetic or maintenance consideration to a critical matter of safety, compliance, and asset protection. The complexity of modern external wall systems means that replacing a façade is no longer a simple construction task; it is a multi-disciplinary engineering project that requires a deep understanding of fire dynamics, structural load, and building regulations.
Recladding a house is the process of removing a building’s existing external wall covering and replacing it with a new, compliant system. In the UK, this work is typically undertaken to resolve issues involving water ingress, structural deterioration, thermal inefficiency, or fire safety non-compliance in multi-storey residential blocks.
A PAS 9980 assessment is a formal methodology used to evaluate the fire risk of external wall systems on multi-storey residential buildings. Introduced by the British Standards Institution (BSI) in early 2022, it provides a structured framework for competent professionals to determine whether a building’s cladding and wall construction pose an acceptable or unacceptable risk to life safety. Rather than focusing solely on whether materials are combustible, the assessment considers the entire wall assembly and how a fire might spread across the building envelope.
Understanding the safety and compliance profile of a building’s exterior is now a central requirement for property professionals across the United Kingdom. A FRAEW assessment is a specialised technical evaluation of the external wall construction of a multi-storey, multi-occupied residential building. Its purpose is to assess the fire risk contributed by the wall system and determine whether remediation or mitigation is necessary to ensure resident safety.
A cladding survey is a comprehensive technical assessment of a building's external wall system, designed to identify material composition, installation quality, and structural integrity. It involves a systematic investigation of the façade—including panels, insulation, cavity barriers, and fixings—to determine compliance with building regulations and assess the need for repair, remediation, or replacement.
Understanding the internal composition of a building’s facade is a critical requirement for modern property management. An intrusive cladding survey is a detailed physical investigation where specialist engineers open up specific sections of an external wall system to inspect hidden components. Unlike visual inspections, these surveys provide definitive evidence regarding the presence of combustible materials, the adequacy of cavity barriers, and the structural integrity of fixing systems.
An external wall survey is a comprehensive technical assessment of a building’s outer envelope, designed to evaluate the safety, compliance, and physical condition of the entire façade system. This professional inspection identifies defects in cladding materials, insulation, cavity barriers, and structural fixings to ensure the building meets current UK fire safety regulations and performance standards.
The EWS1 survey (External Wall System) is a technical assessment process designed to evaluate the fire safety of a building's external wall construction. Introduced by the Royal Institution of Chartered Surveyors (RICS), it results in an EWS1 form that confirms whether the cladding, insulation, and cavity barriers meet specific safety criteria or if remediation is required to mitigate risk.

Higher risk building cladding remediation is the technical process of identifying, removing, or upgrading non-compliant external wall systems on buildings that meet specific height or occupancy criteria under UK law. In the United Kingdom, this primarily concerns residential buildings over 18 metres or seven storeys in height, where the presence of combustible materials presents a significant risk to life safety. Remediation is not merely a cosmetic update; it is a complex engineering and legal requirement designed to ensure that the building envelope prevents the spread of fire and meets the
The safety of a building’s external wall system is a critical concern for property owners and managers across the United Kingdom. Following changes in legislation and building regulations, many structures have been identified as having hazardous façade materials that require immediate attention. Unsafe cladding removal is the systematic process of identifying, stripping, and replacing external wall components that pose a significant fire risk or fail to meet current compliance standards.
Cladding water ingress refers to the uncontrolled penetration of moisture through a building's external wall system into the internal structure or cavity. This failure in the building envelope typically occurs due to defective seals, poor installation of flashing, damaged panels, or systemic design flaws. Left unaddressed, it leads to structural decay, insulation failure, and compromised internal environments.
Spandrel panel remediation is the technical process of investigating, repairing, or replacing the non-vision infill panels located between the glazed areas of a building's façade. These panels, often found in curtain walling and ribbon window systems, are critical for maintaining the thermal performance, moisture resistance, and fire safety of the external wall envelope.
Ensuring the structural integrity of a building’s exterior requires more than just inspecting the visible panels. The cladding subframe replacement process involves the systematic removal and renewal of the hidden metal or timber framework that secures the rainscreen to the building structure.

Following the Grenfell Tower tragedy, the landscape of building safety in the United Kingdom changed permanently. A cladding fire safety survey is now a fundamental requirement for the management of high-rise and multi-storey buildings. These technical assessments are designed to identify combustible materials, verify the presence of adequate fire-stopping, and ensure the entire external wall system meets current life-safety standards.
A cladding inspection is a technical assessment of a building’s external wall system to evaluate its condition, safety, and regulatory compliance. It involves a systematic review of the outer skin, insulation, cavity barriers, and structural fixings to identify defects such as material deterioration, water ingress, or non-compliant fire-safety components. This process provides building owners with the data required to plan repairs, remediation, or full replacement.
A cladding investigation is a technical assessment of a building’s external wall system to identify defects, material composition, and compliance with safety standards. This process involves physical inspections, intrusive testing, and material analysis to determine if the façade is structurally sound, fire-safe, and performing as intended.
Curtain wall systems are among the most complex elements of a building’s exterior. These non-structural outer coverings, typically comprising aluminium frames, glass infill panels, and spandrel sections, are designed to protect the structure from the elements while providing aesthetic appeal. However, when these systems fail due to age, poor installation, or material degradation, the result is often water ingress, thermal inefficiency, or structural instability. Curtain wall remediation is the professional process of identifying these failures and implementing targeted engineering solutions to
Balcony cladding remediation is the technical process of identifying, managing, and rectifying safety and structural defects within the external wall systems surrounding balconies. In the United Kingdom, this often involves addressing non-compliant combustible materials, inadequate fire stopping, and failed waterproofing interfaces that pose risks to life safety and building longevity.
A breather membrane replacement is a specialist remediation process involving the removal of existing external wall layers to install a new, high-performance water-resistant but vapour-permeable layer. This critical component protects the building’s primary structure and insulation from moisture ingress while allowing internal water vapour to escape, preventing interstitial condensation and structural decay.
Cladding bracket replacement is a technical remedial process involving the removal of failed or non-compliant support components within a building's external wall system and installing new, structurally sound fixings. This intervention ensures the façade remains securely attached to the primary structure, maintains required cavity depths, and meets modern fire safety standards. It is typically required when inspections reveal structural fatigue, significant corrosion, or the presence of combustible components within the "helping hand" bracket system.
Cladding rail replacement is the process of removing and renewing the structural framework that secures external façade panels to a building’s primary structure. This infrastructure, often hidden behind the visible rainscreen, is critical for managing wind loads, supporting the weight of the cladding, and ensuring the fire safety performance of the external wall system.
Parapet cladding remediation is the technical process of assessing, repairing, or replacing the external façade elements located at the topmost edge of a building’s wall system. These areas, known as parapets, serve as critical junctions between the roof and the external wall, requiring precise fire stopping, structural integrity, and weatherproofing to ensure the safety of the entire building envelope.
Fire barrier remediation is the technical process of correcting, repairing, or replacing failed cavity barriers and fire stops within a building’s external wall system. This specialist work ensures that in the event of a fire, the concealed gaps behind cladding panels do not act as chimneys that allow flames and smoke to spread rapidly across the facade.
Brick slip cladding remediation refers to the systematic process of investigating, repairing, or replacing decorative thin-clay brick veneers that have failed due to structural issues, moisture ingress, or non-compliance with fire safety regulations. This technical intervention ensures the external wall system meets current UK Building Regulations, specifically regarding thermal performance and fire resistance for multi-storey buildings.

This professional intervention addresses issues ranging from structural instability and moisture-related degradation to fire safety non-compliance, ensuring the building envelope meets current UK Building Regulations and British Standards.
GRC cladding remediation refers to the systematic process of identifying, testing, and rectifying defects in Glass Reinforced Concrete (GRC) facade systems. This process encompasses everything from localised structural repairs to comprehensive GRC cladding replacement where panels have reached the end of their service life or fail to meet modern safety standards.
External wall systems using pre-fabricated units are a staple of modern UK construction. Insulated panel replacement refers to the systematic removal and substitution of composite or sandwich panels that no longer meet thermal, structural, or fire safety standards. This process is essential for maintaining the building envelope’s integrity and ensuring compliance with the Building Safety Act and updated Building Regulations.
SFS remediation refers to the professional investigation, structural repair, or full-scale replacement of Steel Framing Systems (SFS) within a building’s external wall. In the UK, this process is typically required when the light gauge steel framing—which provides the structural skeleton for the façade—is found to be corroded, incorrectly installed, or failing to meet modern fire safety and thermal performance standards. A successful remediation strategy ensures the structural integrity of the building envelope while ensuring compliance with the Building Safety Act and updated Building Regulat
In the complex hierarchy of an external wall system, the sheathing board occupies a critical position. Often hidden behind the decorative cladding and insulation layers, it serves as the primary structural skin of the building’s frame. When this component fails due to moisture ingress, structural movement, or fire safety non-compliance, sheathing board replacement becomes a technical necessity to ensure the long-term viability and safety of the property.
Steel cladding remediation is the process of inspecting, repairing, or replacing external metal wall systems to ensure they meet modern fire safety, structural, and thermal standards. In the UK, this work is essential for high-rise residential and commercial buildings where existing steel façades may have deteriorated or were originally installed without adequate cavity barriers and non-combustible insulation.
Terracotta cladding remediation refers to the specialist process of identifying, managing, and resolving defects within external wall systems that utilise fired-clay tiles or rainscreen panels. This technical intervention ensures that the building envelope remains structurally sound, weather-tight, and compliant with current UK fire safety regulations and Building Regulations (specifically Approved Document B).
External timber facades have long been a popular choice for UK architects and developers, offering a natural aesthetic and strong environmental credentials. However, as buildings age and regulatory standards evolve—particularly following the Building Safety Act 2022—many property owners are finding that these systems require significant intervention.
Zinc cladding remediation is the technical process of identifying, managing, and resolving defects in zinc-based facade systems. This work typically involves structural inspections, moisture analysis, and the repair or replacement of non-compliant components. Effective remediation ensures that the external wall system meets modern fire safety standards, provides weather protection, and maintains the building’s aesthetic integrity.
Cladding adhesion testing is a critical technical assessment used to determine the structural integrity of bonded façade systems. This process measures the tensile strength of the bond between the cladding material and its substrate, ensuring the system can withstand wind loads, thermal expansion, and environmental degradation. For building owners and managing agents, these tests provide empirical evidence of whether a façade remains safe or requires remedial intervention.
Professional cladding testing is a rigorous process used to evaluate the safety, integrity, and regulatory compliance of a building's external wall system. It involves physical sampling, laboratory analysis, and on-site inspections to identify material composition, fire performance, and structural stability. This technical assessment ensures that façades meet current UK building regulations and provides a clear pathway for necessary remediation or repair works.
Ensuring the structural stability of a building envelope requires more than a visual assessment of the exterior panels. Cladding pull out testing is a vital onsite procedure used to measure the physical load-bearing capacity of fixings and anchors within an external wall system. By applying a controlled tensile load to a fastener, engineers can verify that the substrate—whether it be concrete, masonry, or steel—is capable of holding the cladding system securely under environmental stresses such as wind loading and self-weight.
A cladding wind load assessment is a technical engineering evaluation used to determine the specific wind pressures a building’s external wall system must withstand. It involves calculating peak positive (pressure) and negative (suction) forces based on the building's height, location, and geometry to ensure that panels, fixings, and subframes remain structurally secure under extreme weather conditions.
Glass Reinforced Plastic (GRP), often referred to as fibreglass, has been a staple in the UK construction industry for decades. Its lightweight nature, versatility in moulding, and durability made it a popular choice for architectural features, decorative cornices, and modular wall panels. However, as building safety standards evolve and the long-term performance of these materials becomes clearer, many property owners now face the technical challenge of GRP cladding remediation.
