Damp Proofing by Diagnosis

A wavy brown stain creeping up the bottom of a wall in your Amersham home is one of the classic signs that moisture is rising from the ground. We take moisture readings across the affected walls, look at ground levels, gutters and pointing outside, and show you what the readings tell us.

We diagnose and treat damp for homes in Amersham as well as Chesham, Great Missenden and Beaconsfield. You get the moisture readings explained in plain terms and a written price before any work is booked.

Diagnosis Before Any Treatment

We trace the moisture to its source first, so you only pay for the treatment that matches your damp rather than a standard package.

Readings You Can See

We show you the moisture readings and where we took them, so you understand why we are recommending a particular fix.

Walls Made Good

Treatment is followed by repairs to plaster and masonry, so you are left with a sound wall ready for decorating again.

A Vetted Firm

As a Checkatrade member we have been vetted, which gives you extra confidence before letting anyone treat your walls.

Damp Proofing FAQs

Damp Proofing FAQs in Amersham

Do You Carry Out Damp Surveys in Amersham?

Yes. We inspect damp walls for homeowners in Amersham, as well as Chesham, Great Missenden and Beaconsfield. We look at the affected rooms and the outside of the building, take moisture readings and explain whether you have rising damp, penetrating damp or condensation, then send a written quote at a fixed price.

Can You Repair Damp-Damaged Walls in Amersham?

Yes. Once the cause of the damp has been dealt with, we remove plaster that has been spoiled by salts or moisture, repair any failed masonry or pointing and replaster the wall. In Amersham and the other areas we cover, the repairs are set out on the same written quote as the treatment.

How Can I Tell Rising Damp From Condensation?

Rising damp usually shows as a tide mark and salt staining at the base of ground floor walls, and it is there whatever the weather. Condensation tends to appear as black mould on cold surfaces such as window reveals, corners and outside walls, and it gets worse in winter when windows are shut. Moisture readings help confirm which you have.

Does Every Damp Wall Need a New Damp Proof Course?

No. A new damp proof course only helps with genuine rising damp. Many damp walls are caused by rain getting through the masonry, a damp course that has been bridged by soil or a path, or condensation inside the room. Injecting a wall that has a different problem will not dry it out, which is why we diagnose before recommending anything.

Why Does Plaster Have to Be Removed After Treatment?

Moisture rising through a wall carries salts from the ground, and these collect in the plaster. Even once the source is stopped, salty plaster keeps drawing moisture from the air and stays damp to the touch. Removing it and replastering with a suitable mix gives you a dry surface that will take paint or paper properly.

How Long Does a Wall Take to Dry Out?

It depends on how wet the wall was, how thick it is, what it is built from and the time of year. Solid walls in older houses can take many months to dry fully. We will explain what to expect for your wall and when it is sensible to decorate, so new paint or paper is not spoiled by lingering moisture.
