Damp Proofing
Rising damp, penetrating damp and condensation diagnosed and treated. Chemical DPC injection, replastering with salt-inhibiting render and guaranteed results in period and modern properties.
Damp proofing services →Basement Waterproofing
Full design and installation to BS 8102 for basements, cellars and vaults. Type A barrier, Type B structural and Type C cavity drain systems for conversions, new builds and remedial work.
Basement waterproofing →Cavity Drain Membranes
Newton certified installation of cavity drain membrane systems with sumps, pumps and maintainable drainage. The modern standard for keeping below-ground spaces permanently dry.
Cavity drain systems →Basement & Cellar Tanking
Cementitious tanking systems that turn wet cellars into dry, usable space. Properly prepared substrates, correct products and workmanship backed by written guarantees.
Basement tanking →Condensation & Mould
Black mould is a symptom. We identify whether the cause is ventilation, insulation or an underlying damp problem, then fix the source so the mould does not come back.
Condensation solutions →Damp & Waterproofing Surveys
Professional surveys with moisture profiling, salts analysis and thermal imaging where needed. You get a written report with the cause, the fix and the cost. Fee deducted if works proceed.

How We Work
A structured, assessment-led process. Treatment is never recommended before the cause is established.
Technical Survey
A qualified specialist inspects the property, assessing construction type, ground levels, moisture patterns and structural factors.
Accurate Diagnosis
Moisture profiling, salts analysis and thermal imaging where needed identify the root cause, not just the visible symptoms.
Clear Specification
You receive a written report setting out the recommended system, whether that is damp proofing, tanking or a cavity drain membrane.
Specialist Installation
Trained technicians install to manufacturer specification and recognised best practice, backed by a written guarantee.

What Customers Say
Real reviews from recent damp proofing and waterproofing projects.
"Highly professional damp treatment"
"The team was professional and really clear when explaining the whole damp treatment process, including the follow-up steps and advice on another damp-prone area in our home. They arrived on time and made sure to clean up after themselves. What stood out most was how quickly they responded and managed to fit us in on short notice."
Bruce"No unnecessary upselling"
"Customer service was excellent from start to finish. There was no unnecessary upselling, and they used top-quality materials. The surveyor clearly explained the entire process, and despite the inevitable dust they kept everything clean and protected, especially the flooring. The finished work was of a really high standard."
Jane"Sorted quickly and efficiently"
"I was contacted by Robert, who was both personable and highly professional. He immediately put me at ease and took the time to thoroughly explain the entire process, which was especially reassuring since this was my first experience dealing with damp proofing. It made the whole experience much smoother and far less daunting."
