Damp Proofing in Chester
Damp in Chester — whether it's rising up from the ground, getting in from outside, or condensation building up inside — is diagnosed by survey and treated at the source, with the price agreed before we start. We're out across Cheshire regularly, so most enquiries get a survey within days.
Quick answer
Damp proofing in Chester starts with a free survey to diagnose whether it's rising, penetrating or condensation damp, followed by a fixed written quote. Most single-wall treatments start from around £350, with the work carried out at the source and backed by a written guarantee.
How does damp proofing work in Chester?
In the North of England, older solid-brick and stone properties are common, and exposure to driving rain makes penetrating damp through failed pointing and render a frequent cause alongside classic rising damp.
Getting the diagnosis right is everything with damp in Chester — rising, penetrating and condensation damp look similar but are treated in completely different ways, so we always survey and confirm the cause before quoting rather than guessing from a photo.

Is the damp survey really free?
For most straightforward domestic jobs, yes — a survey and fixed quote are free with no obligation. A detailed independent report (for a house purchase, mortgage or dispute) is a paid, separate service, which we confirm up front.
What is a damp-proof course (DPC)?
A DPC is a barrier that stops ground moisture rising up through a wall. Older properties may have a failed or missing one; we install a new chemical DPC by injecting a water-repellent cream into the mortar course, which cures to form a continuous barrier.
Do I need to re-plaster after damp treatment?
Usually, yes. Rising damp carries salts into the plaster that keep drawing moisture even after the DPC is in, so the affected plaster is removed and replaced with a salt-resistant system. This is what lets the wall dry out and be redecorated without the problem coming back through.
How quickly can you survey a property in Chester?
We cover Chester regularly and can usually arrange a survey within a few working days — sooner for urgent cases such as a sale falling through on a damp report.
Is your damp proofing work guaranteed?
Yes — damp-proof course treatments are carried out to industry standards and backed by a written workmanship guarantee. We confirm the exact terms and length in your quote before any work starts.
Can you treat woodworm and rotten timber too?
Yes. Damp and timber problems usually go together — where damp has caused wet rot, dry rot or woodworm in joists, skirtings or timbers, we treat the timber as part of the same visit once the moisture source is dealt with.
Damp is treated by cause, not by symptom: rising, penetrating and condensation damp look similar but need completely different treatments, which is why every job starts with a proper survey and diagnosis before any work is quoted.
