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.

janine jordan
I don’t normally write reviews, but I honestly can’t fault Environ Property Services or their customer service. I was very stressed with the work that needed doing as I’m super busy, however from the very first visit the team took full control, reassured me, and followed through seamlessly.

Don’t you love it when a company lives up to its reviews? I needed the drains and gutters checked and cleared. Booking through Emily was easy and she gave me various options to choose from. Ben and Jack arrived on time, carried out all the work professionally and gave detailed feedback before they left.

Aidan and Ian went above and beyond to sort out our drains and hopefully future proof them. Lovely guys who did everything they could to try and solve some complex problems we have. I’d recommend them to anyone requiring similar work

Environ responded to my enquiry within hours, they were able to give me an appointment quite quickly and they communicated well with me via email. When the operatives arrived to carry out the work they were friendly, polite and helpful. They also resolved the problem.
