Fabric & Building Envelope
The external envelope, end to end — from rainscreen and curtain walling to flat and pitched roofing. With the Building Safety Act reshaping façade work, our compliance-led approach to remediation and Higher-Risk Buildings is the sharpest reason to put fabric with us.

From survey to handover —
and beyond.
- 01
Survey & fire-strategy review
We survey the existing envelope, assess its condition and review the fire strategy — checking cladding, render, roofing and façade against Part B and the building’s risk profile before a brick is touched.
- 02
Design & specification
Coordinated design and specification for cladding, rainscreen, curtain walling, render or EWI — thermal performance to Part L, fire performance to BS 8414 / BR 135, and a fully traceable spec.
- 03
Access & enabling
Scaffold, MEWPs and mast-climbers planned and erected safely around occupied buildings, with the enabling and strip-out works that the new envelope depends on.
- 04
Envelope installation
Rainscreen, render, curtain walling, roofing, EWI and façade repairs self-delivered to the approved spec — sequenced elevation-by-elevation to keep the building weather-tight throughout.
- 05
Inspection, handover & warranties
Inspection and testing against the specification, a complete records pack, then a clean handover with product and workmanship warranties — and planned maintenance if you want us to keep the envelope sound.
Built to the codes that
matter on handover.

Envelope questions,
answered.
Do you carry out cladding remediation and building-safety works?
Yes. We deliver cladding remediation and façade safety works on higher-risk buildings under the Building Safety Act 2022 — from intrusive survey and strip-out through to a compliant, fully documented replacement envelope.
How do you ensure fire compliance (BS 8414 / Part B)?
We specify and install systems with cladding fire performance assessed to BS 8414 against the BR 135 criteria, all designed to meet Building Regulations Part B. Every system is traceable, with product data and records retained for the building’s safety case.
Do you do external wall insulation and retrofit (PAS 2035)?
Yes. We deliver external wall insulation (EWI) and fabric retrofit within the PAS 2030 / 2035 framework, improving thermal performance to Part L while keeping the fire strategy and detailing correct.
Can you work on occupied buildings and at height safely?
Yes. Most envelope work is at height around live, occupied buildings. We plan access — scaffold, MEWPs and mast-climbers — and sequence the works elevation-by-elevation under CDM 2015 to keep residents and the public safe.
What warranties come with the envelope?
You get manufacturer product warranties on the cladding, render, roofing or insulation system, backed by our workmanship warranty — plus a full records pack covering the specification, installation and inspection.
Which areas do you cover?
We deliver fabric and building-envelope packages across London and the South East, including Sussex, Surrey, Kent, Hampshire and Berkshire. Send us the site address and we’ll arrange a survey.
