Damp on the wall? Tap what you see.

What can you see?

Likely rising damp

Brown staining up to 1m high, salty plaster, rotting skirting.

What we do: A new damp proof course, then salt-retardant replastering.

“Damp proofing to my front lounge, they did an excellent job. Clean and tidy and I would highly recommend.”

Likely penetrating damp

Damp patches that get worse after rain, often with blown render, crumbling mortar or a stained ceiling.

What we do: We find the fault outside, like a blocked gutter or cracked brick, fix it and seal the brick with a silane water repellent.

Likely condensation

Black spots in corners or behind furniture, streaming windows and a musty smell.

What we do: Positive Input Ventilation (PIV) and extractor fans to keep fresh air moving. A PIV unit costs 1p to 2p a day to run.

Possibly dry or wet rot

An earthy, mushroom-like smell under floors or in the loft, white cotton wool growth, orange dust or deeply cracked wood.

What we do: A timber survey, then the rot is treated at the source and joists repaired or replaced. Rot spreads, so don’t wait.

Damp on the lower walls of a cellar, basement or a house built into a slope.

Put back, not just treated

Barrier are builders too, so after the damp course or tanking they replaster and finish the room. Kitchens and bathrooms as well, if you want them.
