Decanting During Cladding Remediation

Managing a major external wall project requires more than just technical engineering; it demands a comprehensive logistical strategy. One of the most significant decisions building owners and managing agents face is whether residents can remain in their homes while work is underway. Decanting during cladding remediation refers to the temporary relocation of residents from their units to alternative accommodation to facilitate safe, efficient, and intensive façade works.

At CladdingTesting.com, we understand that moving residents is a high-stakes decision involving significant legal, financial, and emotional considerations. It is rarely the first choice, but in specific scenarios involving structural instability, high fire risk, or invasive internal-to-external wall ties, it becomes a necessity for safety and project delivery.

Key Takeaways#

• Safety First: The primary driver for decanting is resident safety, particularly when fire escape routes are compromised or structural risks are identified.
• Individual Assessment: Whether residents move out during recladding depends on the building’s specific design, the extent of the remediation, and the level of internal disruption.
• Cost-Benefit Analysis: While decanting is expensive, it can significantly accelerate the construction programme, potentially reducing overall project costs.
• Legal Compliance: Managing agents must navigate complex leasehold agreements and statutory duties of care when arranging a temporary decant for cladding works.
• Communication is Critical: Success depends on transparent, early, and consistent engagement with all affected stakeholders.

Decanting during cladding remediation is the process of temporarily moving residents out of a building to allow for extensive façade replacement or structural wall repairs. This occurs when the scale of work, level of noise, or compromise to life safety systems makes the building uninhabitable for the duration of the project.

• Temporary decant cladding works: A planned relocation lasting from a few weeks to several months.
• Partial Decanting: Moving residents only from specific elevations or floors as the work progresses.
• Full Decanting: Vacating the entire building to allow for a comprehensive, accelerated recladding programme.

Do Residents Move Out During Recladding?#

In the majority of UK remediation projects, recladding while residents stay is the preferred approach. Modern scaffolding systems and mast climbers allow specialists to work on the exterior without entering individual apartments. However, this is not always feasible or safe.

The decision typically hinges on the External Wall System (EWS) design. If the remediation requires removing the inner leaf of the wall, or if the fire strategy relies on "stay put" advice that cannot be guaranteed during the works, a decant may be mandatory. At CladdingTesting.com, we evaluate every building individually to determine the least disruptive path forward.

When Staying Put is Feasible#

Residents usually stay in situ if the work is restricted to the outer cladding panels, cavity barriers, and insulation. In these cases, the primary challenges are noise, loss of light due to scaffolding, and privacy concerns. These are managed through robust "good neighbour" policies and restricted working hours.

When Decanting is Necessary#

Decanting becomes the lead option when the building’s structural integrity is at risk, or when the remediation involves the removal of glazing and internal finishes. If the "line of compartmentation" is breached—meaning fire cannot be contained within a single flat during the work—the building effectively fails its life safety requirements for occupancy.

Triggers for Temporary Decant Cladding Works#

Identifying the need for a decant early in the cladding works decanting residents process is vital for budgeting and procurement. There are four primary triggers that usually necessitate a move.

1. Fire Safety and Life Safety Risks#

If a fire risk assessment (FRAEW) suggests that the existing cladding is so hazardous that a "waking watch" is insufficient during the removal phase, decanting may be the only way to satisfy insurers and the fire service. If the building’s primary fire escape routes are blocked by construction activity, the building cannot remain occupied.

2. Structural Integrity and Stability#

During cladding remediation, we occasionally find that the underlying substrate (the material the cladding is fixed to) is failing. If the removal of panels risks the stability of the remaining façade or the internal walls, the area must be cleared of residents to prevent injury from potential collapses.

3. Environmental and Health Factors#

Extensive recladding can involve significant dust, vibration, and noise. For vulnerable residents, those working from home, or buildings where hazardous materials like asbestos are found within the wall cavity, temporary decant cladding works provide a necessary health safeguard. The psychological impact of living in a "wrapped" building with no natural light for 12-18 months is also a factor.

4. Access Requirements#

Some façade systems require fixings to be installed from the inside out. This involves contractors entering every habitable room, moving furniture, and cutting into plasterboard. Maintaining a domestic life during such invasive work is often impossible, leading managing agents to conclude that residents move out during recladding for these specific phases.

The Challenges of Recladding While Residents Stay#

While staying in situ avoids the logistical nightmare of finding alternative housing, it introduces its own set of complex challenges for the façade contractor and the building manager.

Noise and Vibration Management#

Drilling into concrete or steel frames creates significant acoustic distress throughout a high-rise building. Contractors must use "quiet" technologies where possible and adhere to strict time slots, but for residents, the disruption remains the number one complaint. Clear communication regarding the schedule of noisy works is essential.

Privacy and Security#

With workmen on scaffolding outside windows, privacy is effectively lost. This requires residents to keep blinds closed for extended periods, which impacts mental health and ventilation. Furthermore, scaffolding provides a potential route for intruders, necessitating enhanced site security, CCTV, and alarm systems on the gantries.

Loss of Amenity#

Balconies are typically decommissioned and used for storage or access during cladding works. The loss of outdoor space, combined with the "netting" of the building which reduces natural light, can make the living environment feel claustrophobic. Managing these expectations is a core part of the resident liaison officer's role.

Logistics of Cladding Works Decanting Residents#

If the decision is made that decanting during cladding remediation is required, the logistical operation must be planned with military precision. This isn't just a construction project; it's a relocation project.

Alternative Accommodation Sourcing#

Finding suitable, local accommodation for 50 to 200 households simultaneously is a massive undertaking. Options include:

• Serviced Apartments: Ideal for short-term decants but expensive.
• Rental Market: Hard to secure for fixed terms that match construction schedules.
• Hotel Placements: Only suitable for very short, emergency interventions.
• Phase-based Relocation: Moving residents from one wing of a building to another or to a nearby sister-development.

Financial Responsibility#

Who pays for the decant? This is often the most contentious point. Depending on the building’s age and the nature of the defect, funding may come from:

• The Building Safety Fund (BSF) or the Cladding Safety Scheme (CSS).
• Developer Pledges: Many major UK developers have signed a pledge to remediate buildings they built.
• Professional Indemnity Insurance: If the decant is caused by a design or installation error.
• Service Charge: Only as a last resort, and subject to legal challenges under the Building Safety Act 2022.

The "Moving Day" Protocol#

A professional decant strategy includes professional packing services, secure storage for excess furniture, and mail redirection. For residents with disabilities, the alternative accommodation must meet specific accessibility requirements (DDA compliance). Failure to address these details can lead to significant delays in the construction start date.
