Dry Walls Again

Damp Proofing Your Home

Damp is a symptom, and the same stain on a wall can come from three very different places. Rising damp draws moisture up from the ground, penetrating damp lets rain in through the outside wall, and condensation forms when moist indoor air meets a cold surface.

Treating the wrong one wastes your money and leaves the problem in place, so we start by working out which you have. The treatment then follows the cause: a new damp proof course, sealing and repairing the outer wall, or improving ventilation where condensation is to blame.

Where rain is soaking through cracked or blown render on an outside wall, putting the damp right often goes hand in hand with rendering and exterior painting, so the wall is sealed against the weather once the inside has dried out.

Signs Your Walls Need Damp Proofing

These are the warning signs homeowners most often notice first. If you see any of them, it is worth having the wall looked at before the damage spreads further.

Tide Marks Low Down

A wavy stain or white salty bloom along the bottom of a wall, up to about a metre high, often points to rising damp.

Crumbling Plaster

Plaster that sounds hollow, bubbles or turns powdery, and paint or wallpaper that keeps lifting, are signs of moisture.

Patches After Rain

Damp spots that appear or grow darker after heavy rain usually mean water is getting through the outside wall itself.

Mould & Musty Smells

Black mould in corners, behind furniture or around windows, and a stale smell, tend to come from condensation indoors.

Damp Proofing FAQs

Damp Proofing FAQs

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.

Can Condensation Be Cured Without Building Work?

Often, yes. Condensation comes from moisture produced indoors by cooking, washing and drying clothes. Better ventilation, such as extractor fans in kitchens and bathrooms or trickle vents in windows, and keeping rooms evenly heated, usually makes a big difference. We can look at your home, explain where the moisture is collecting and suggest the changes most likely to help.
