Many operators want to cash in quick — low prices, payment up front, and work that isn’t up to standard. The damp comes back in a year or two and you pay all over again. We take a very different approach.
Decades of knowledge of the water table, rivers, soil types and construction across London — so your problem is diagnosed correctly, first time.
Our surveyors earn no commission and no bonus for extra work. In one or two of every ten surveys we recommend no work at all.
Not two standard methods, but a combination of techniques chosen to cure your particular problem — including our own proprietary materials.
Written guarantees among the longest in the industry — up to 50 years — and fully transferable if you sell your property.
We provide exactly the right solution for your situation, using a combination of specialist techniques.
A damp-proof course injected into the brickwork to stop moisture rising, backed by our 20-year guarantee.
The most durable cure of all — a physical DPC we guarantee for 50 years and have never had to return to repair.
Turn a damp, cold cellar into a dry, habitable room with the correct tanking system for your property.
