Root Cause Damp Resolution. Verified. Certified
Environ’s Total Envelope Protocol™ is a uniquely qualified, three-stage system designed to eliminate damp permanently — not temporarily.
Unlike generic damp contractors, we don’t upsell tanking. We don’t make assumptions. We work with a multi-disciplinary team of certified surveyors across:
No other company in London brings together this level of in-house, cross-discipline diagnostic power to find and eliminate damp at the true point of entry — structurally, environmentally, and permanently.
❝ Most companies treat walls, We inspect buildings.❞
How the Total Envelope Protocol™ Works
Diagnose the Source
We start with forensic-level surveys,
carried out by PCA-trained specialists supported by roofing, drainage, and heritage building experts.
We don’t just point moisture meters and speculate — we provide photographic evidence, moisture migration mapping, and documented ingress points.
This means:
- No guesswork.
- No inflated treatments.
- No unnecessary works.
- Long term Solutions
Dry and Stabilise
Once the source of moisture is resolved (leaking roof, faulty drains, or bridging render), we allow the structure to dry in line with building science — not impatience.
We monitor moisture release, stabilise humidity, and refuse to treat surfaces that aren’t ready.
Most companies skip this stage. We don’t. Because rushing to treat a wet wall is why
other systems fail.
Treat and Restore
Only when the structure is dry and verified, do we proceed with the final stage:
- Breathable plasters
- Isolation membranes
- Internal rebuilds and finishes
- Heritage-appropriate
- materials (lime,
render, breathable masonry) - Completion Report
- Guarantees
Each treatment is backed by documentation, and designed with building type, age, and environment in mind.
Because we’re not tied to one manufacturer, our only allegiance is to the long-term health
of the building.

Our in-house specialists from Roofing, Drainage, Pest, and Restoration all contribute to each case — coordinated, scheduled, and aligned under one protocol.

This isn’t just paperwork — it’s third-party verification that we deliver professional outcomes across multiple trade disciplines. Our reports are used by architects, managing agents, surveyors, and insurance teams.
Process Before Products
We never lead with treatments. We lead with evidence, structure, and clarity — because that’s what prevents call-backs, client complaints, and wasted spend.
Trusted by London’s Best
Property managers, conservation architects, high-net-worth homeowners and investors trust Environ to safeguard their buildings, not just fix their walls. We’re called when others fail — and stay when others walk away.
