Damp, Mould
& Waterproofing

Everything we do, in one place. Whatever you have come here for, it starts the same way — a survey that establishes the cause before anybody recommends a treatment.

Five Disciplines,One Team

We do not sub-contract the diagnosis to one company and the work to another. The surveyor who writes your report works for the business that carries out the repair and stands behind the guarantee.

Damp Surveys

Moisture profiling, salts analysis and thermal imaging, written up as a report you can act on — or hand to a lender, landlord or solicitor. Fee deducted from works.

Damp Proofing

Rising and penetrating damp. Injected damp proof courses, salt-inhibiting render systems, external repair and repointing — specified for the construction you actually have.

Related WorkWe Carry Out

Damp is rarely a standalone problem. Because we sit inside a property repairs business, the associated work does not need a second contractor and a second programme.

Ventilation & PIV

Positive input ventilation units, continuous-running extract fans, humidity-sensing bathroom extraction and sub-floor ventilation.

Leak Investigation

Tracing intermittent or unexplained water ingress using thermal imaging, moisture mapping and controlled testing.

Plastering & Making Good

Renders, skims, cornice and joinery reinstated properly after remedial work, rather than left for you to arrange.

External Repairs

Repointing, brick replacement, render repair, rainwater goods, flashings and ground level reduction — the actual cause, in many cases.

How We Work

Assessment First,Treatment Second

Four steps, every job, residential or commercial.

The order is the point. A specification written before the cause is established is a guess with a price on it, and the industry's poor reputation for damp work comes almost entirely from that one shortcut.

1

Technical Survey

Full inspection inside and out, including ground levels, drainage, ventilation and construction type.

2

Accurate Diagnosis

Moisture profiling, salts analysis and thermal imaging to find the root cause rather than the symptom.

3

Clear Specification

A written report with the recommended system, the scope and an itemised fixed price.

4

Specialist Installation

Installed to manufacturer specification by trained technicians, with a written guarantee.

Credentials

Built on Diagnosis,Not Guesswork

Damp is one of the most misdiagnosed problems in UK housing, and the wrong treatment costs more than the right one. Our surveys come before any recommendation, and our team is trained to the standards the industry actually recognises.
