Our proven 3-stage process has made us one of the most trusted names in professional damp treatment.

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.

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

Stage 1

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

Stage 2

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.

Stage 3

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.

What Makes Environ Stand Out

We’re not just a damp company.

 Trustindex verifies that the original source of the review is Google. Helped with survey and repair of water ingress from outside and into our basement. Professional throughout and very efficient in getting the job arranged in a short timescale. Special mention to David (damp surveyor), Daniel Bird (restorer) and Simone (project coordinator).

 Trustindex verifies that the original source of the review is Google. From my initial call with Faeeza through to the inspection carried out by David Crane, both were highly professional and reassuring throughout.

My issue was urgent, and they accommodated my requirements with care and due diligence.

David undertook a thorough inspection, identified several potential causes of the ceiling leak and provided helpful advice accordingly, followed by an in-depth report.

I would gladly recommend Environ Property Services Ltd.

 Trustindex verifies that the original source of the review is Google. I engaged Environ Property Services to investigate longstanding damp and mould problems at my property.

I was particularly impressed with Juan van der Merwe and surveyor David Crane. They carried out a thorough investigation, including a return visit and a drone roof survey, which identified significant issues with the external guttering and rainwater drainage system.

Their final report was detailed, supported by photographic evidence, and clearly explained the likely causes of the damp together with the recommended remedial action.

What particularly impressed me was their willingness to go the extra mile. The additional drone survey was undertaken as a gesture of goodwill, without further charge.

Juan was professional, helpful and proactive throughout, including communicating the findings directly to the relevant parties.

It is refreshing to deal with a company that takes the time to investigate the underlying cause rather than simply recommend treating the visible symptoms.

I recommend Environ Property Services for damp investigations and surveys.

 Trustindex verifies that the original source of the review is Google. David did an outstanding job carrying out our survey. From the outset, he put us completely at ease regarding the issue being investigated, and every stage of the process was explained clearly, including what would happen next.

His level of professionalism, knowledge, and expertise was exceptional. The area of concern was assessed and inspected thoroughly, along with other related areas, and his approach was highly methodical and extremely comprehensive. It was evident that no detail was overlooked.

What particularly impressed us was the additional advice and recommendations he provided regarding the further assessment of certain areas. This went far beyond our expectations and gave us great confidence in both the findings and the way the issue would be managed moving forward.

It is clear that David possesses exceptional expertise in his field, and this was reflected throughout the survey and in the quality of his work. His professionalism, attention to detail, and willingness to go above and beyond were truly remarkable.

I would also like to thank Faeeza, who was approachable, friendly, and extremely informative. She ensured that we understood all aspects of the appointment and explained everything clearly and professionally.

Overall, I am genuinely impressed with the company and the high standard of service we received. Based on our experience, I would recommend the company without hesitation.
