Damp Proofing in Windsor
Peeling walls, lingering damp odours, or bubbling plaster? These are more than surface issues. Elmbridge Damp Proofing delivers lasting protection for Windsor properties.

It Doesn’t Fix Itself
Damp Won’t Disappear on Its Own
A small stain today can grow into major structural damage tomorrow. Windsor homes, from historic terraces near the Castle to family properties around Dedworth and Clewer, are particularly vulnerable to rising damp and condensation problems lurking out of sight.
We Don’t Patch Over Damp. We Eliminate It.
We offer a full diagnostic and treatment service, including:

Rising Damp Treatment
Safeguard your Windsor property against rising damp. Our specialists trace the problem to its source and apply long-lasting treatments that protect walls, floors and finishes.

PIV Unit Installation
Enhance indoor air quality with a professionally installed Positive Input Ventilation (PIV) system. Designed to cut humidity, control condensation and prevent mould in Windsor homes.

Condensation & Mould Solutions
We tackle the root causes of condensation and black mould with tailored ventilation and moisture-management strategies, helping Windsor households stay healthy and damp-free.

Penetrating Damp Repairs
From cracked render to porous brickwork, we provide effective repairs that block water ingress and shield Windsor properties from penetrating damp damage.

Damp Proof Course Injection (DPC)
Our quick, reliable DPC injection service creates a strong moisture barrier within your walls, stopping rising damp and protecting your Windsor home for the long term.

Timber Preservation & Waterproof Membranes
Decay in structural timbers can lead to costly repairs. We use specialist preservation treatments and robust membrane systems to keep Windsor joists, beams and floors secure and dry.
The Longer You Delay, The Worse It Gets
Damp doesn’t sit still, it seeps through brickwork, creeps beneath flooring, and hides inside walls. By the time you notice, repairs can be costly. Arrange your free Windsor survey today and tackle it before it escalates.

I live in a bungalow my child has asthma she was increasingly getting worse. Mould had developed in several areas of the house. Edp diagnosed rising damp and priced competitively. Really happy with the service.

EPD recommended a P.I.V unit to combat the condensation issues. Really nice installation and literally two days later, there was no condensation at all.

Frequently Asked Questions
Do you provide damp surveys in Windsor SL4?
Yes. We carry out professional damp surveys across Windsor and the surrounding SL4 area. Our surveyors identify the source of damp problems and recommend the most effective treatment, whether it’s rising damp, condensation, or penetrating damp.
How much does damp proofing cost in Windsor?
The price of damp proofing in Windsor varies depending on the type and extent of the issue. Small, localised treatments can be a few hundred pounds, while larger projects that involve multiple rooms or a new damp proof course (DPC) will cost more. We provide detailed quotes after a survey so you know exactly what to expect.
How long does it take to install a damp proof course?
Most DPC installations in Windsor homes can be completed in just a few days, although the exact timeframe depends on the property size and how much plasterwork needs replacing afterwards. We’ll always give you a clear schedule before any work begins.
Can you remove black mould safely?
Yes. Our team uses safe, industry-approved methods to remove black mould from walls, ceilings and other surfaces in Windsor properties. More importantly, we also address the damp conditions that caused it, preventing the mould from returning.
Is damp proofing covered by insurance in Windsor homes?
Standard home insurance policies in Windsor don’t usually cover damp proofing because damp is often seen as a maintenance issue. However, it’s worth checking with your insurer, as some policies may cover related damage or emergencies.
Do you offer damp proofing for landlords in Windsor?
Absolutely. We work with landlords and letting agents throughout Windsor, helping protect rental properties from damp and mould. Regular surveys and treatments can keep tenants safe and reduce long-term repair costs.
