Residential façade remediation is the process of investigating, designing for and correcting defects in the external wall of a residential building — most commonly combustible or non-compliant cladding, but also failed cavity barriers, deteriorated render, water ingress, ageing curtain walling and defective windows or balconies.
Residential buildings can require investigation or remediation for a number of reasons: a fire risk assessment or FRAEW identifying a defect, a lender requesting an EWS1 form before a sale or remortgage can proceed, visible deterioration or water ingress, or a managing agent or resident raising a concern directly.
What’s actually required depends heavily on the building itself. A 1960s local authority block, a 2000s private apartment scheme and a 2015 purpose-built development will typically have entirely different wall constructions, insulation types and cladding systems — and therefore different defects, different risks and different remediation routes.
We work across the full range of residential building types, including:
Residential buildings can be affected by a range of façade defects, including:
Our Common Façade Problems & Defects guide covers these issues in more detail.

Remediation should always start with evidence, not assumption. For most residential buildings, that means a route from initial concern through to a defined remediation strategy:
Initial concern → survey and opening-up investigation → assessment (including FRAEW to PAS 9980:2022, where relevant) → remediation strategy
Trident works across design, procurement and delivery. The initial condition surveys and intrusive investigations are carried out by our sister company, Trident Facades Surveys, who specialise in façade condition surveys, opening-up investigations, PAS 9980 assessments, FRAEW and EWS1. If your residential building hasn’t yet been surveyed, that’s the right place to start — see our Façade Surveys for Remediation page for more detail.
The appropriate remediation route depends on the findings of the survey and assessment. Options can include:
For many residential buildings, particularly those with multiple dwellings, remediation is closely tied to building and fire safety requirements introduced following the Grenfell Tower fire. Where a FRAEW or fire risk assessment identifies risk in the external wall, remediation is often the route to addressing it, and funding eligibility, insurance and lender requirements (including EWS1) can all depend on that assessment being in place.
Funding and grant support for residential façade remediation is available in some circumstances, depending on your building’s height, location, construction and the risk identified in an assessment. Eligibility criteria can change, so it’s worth checking your building’s current position rather than relying on assumptions from a previous scheme. Use our Funding Eligibility Checker on the homepage for an initial indication of which route may apply to your building.
Unlike new-build construction, residential remediation almost always takes place around people living in the building. We plan every project around that constraint, including:
Does every residential building need a FRAEW?
Not automatically — but where a residential building has an external wall system that could allow fire to spread, the Building Safety Act 2022 and Fire Safety (England) Regulations 2022 require building owners to assess that risk. A FRAEW, carried out to PAS 9980:2022, is the standard method for doing so.
What typically triggers façade remediation on a residential building?
Common triggers include a FRAEW or fire risk assessment identifying a defect, a lender requesting an EWS1 form before a sale or remortgage, visible deterioration or water ingress, or concerns raised by residents, insurers or a managing agent.
Can residents stay in their homes during remediation?
In most cases, yes. Residential remediation is usually phased and planned specifically to allow residents to remain in occupation, with access, noise and disruption managed throughout — see the section above on working on occupied buildings.
How long does residential façade remediation take?
This depends on the building’s size, the extent of the defect and the scope of works agreed. A single elevation repair can take weeks; a full high-rise re-cladding programme can take a year or more. Your remediation strategy should set out a realistic programme once the scope is confirmed.
I’m a leaseholder — can I arrange remediation myself?
Generally, no. Responsibility for external repairs, and for applying for remediation funding, usually sits with the freeholder, managing agent or Resident Management Company, not with individual leaseholders. If you’re a leaseholder concerned about your building’s façade, the right step is usually to raise it with your freeholder or managing agent directly.
What’s the difference between repair, remediation and replacement?
Repair addresses a localised defect. Remediation is the broader process of investigating and correcting the underlying risk, which may include repair, partial replacement or full system replacement depending on what the survey finds.
Who pays for residential façade remediation?
This depends on the building, the defect and current funding eligibility. Some projects are funded through schemes such as the Cladding Safety Scheme, others through the responsible developer, and others directly by the freeholder or building owner. Our Funding Eligibility Checker gives an initial indication of which route may apply.
Will my building need scaffolding for the whole project?
Not necessarily — access requirements depend on the scope of works and building height, and can include scaffolding, MEWPs, or a mix of both across different phases. This is confirmed during the design stage.
