Damp Proofing in Hersham, Surrey
Damp patches, flaking plaster, a musty smell, don’t ignore the signs. Elmbridge Damp Proofing protects Hersham homes for good.

It Doesn’t Fix Itself
Damp Doesn’t Wait
What starts as a patch on the wall often ends in costly structural repairs. Hersham homes, especially period properties near The Green and residential builds along Queens Road, are especially prone to hidden rising damp and condensation issues.

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 Hersham KT12?
Yes. We offer free, no-obligation damp surveys for homeowners and landlords in Hersham KT12. Our local surveyor will assess signs of damp, identify the root cause, and explain your treatment options clearly, no pressure, no guesswork.
How much does damp proofing cost in Hersham?
Costs vary depending on the type and severity of damp. For example:
DPC injection: from £300–£1,200
Basement tanking: from £2,000+
Condensation control: from £400+
We always provide fixed quotes after survey.
How long does DPC take to install?
Most damp proof course injections (DPCs) take 1–2 days to complete, depending on the size of the affected area. Drying time varies but we’ll guide you through redecoration timelines and any necessary plastering.
Can you remove black mould safely?
Yes. We use professional mould remediation techniques that are safe, certified, and highly effective. But mould is usually a symptom of a deeper damp or ventilation issue—we identify and treat the root cause so it doesn’t return.
Is damp proofing covered by insurance in Hersham homes?
In most cases, standard home insurance doesn’t cover pre-existing damp or damage from poor maintenance. However, if damp is caused by an insured event (like flooding or a leak), it may be covered. We can provide a written report to support insurance claims if needed.
Do you offer damp proofing for landlords in Hersham?
Yes. We work with landlords and letting agents across Hersham to resolve damp issues quickly and with minimal disruption to tenants. We can also provide documentation for compliance and tenant communication.
