Why sort damp out sooner rather than later
Wales has the oldest housing stock in the UK. Over a quarter of homes here were built before damp-proof courses were standard, and the Welsh Housing Conditions Survey found damp or condensation problems in 7% of Welsh homes, rising to 13% in privately rented properties, with rising damp specifically affecting 2% of dwellings and penetrating damp around 4%.
Age is a big part of why. A House of Commons Library briefing found damp problems in 10.3% of homes built before 1919, against just 1% of homes built after 1981. Given how much of Wales's older housing sits in areas like Ammanford and the Amman Valley, it's worth taking early signs seriously rather than waiting for them to spread.
Left alone, damp damages plaster and brickwork, can make breathing problems worse, and it's one of the things a mortgage survey is likely to flag if you're selling. Checkatrade's own data puts the average cost of damp proofing in Ammanford at £1,400, with most jobs landing between £962 and £2,076. A survey tells you which end of that range you're actually looking at.
Signs you might have damp
- A musty smell that doesn't go away with airing
- Black mould on walls, ceilings or around windows
- Wallpaper peeling or plaster crumbling
- Paint flaking or bubbling
- Damp patches or tide marks on internal walls
Types of damp we cover
Rising damp
Groundwater drawn up through brickwork because the damp-proof course has failed, or was never fitted. Common in older Welsh terraces and cottages.
Read about rising damp →Penetrating damp
Water getting in from outside through a wall, roof or window rather than up from the ground. Usually traced back to a specific defect, like cracked render or a blocked gutter.
Read about penetrating damp →Condensation
Moisture from cooking, showers and breathing that has nowhere to go, made worse by poor ventilation. The most common damp problem in modern, well-insulated homes.

Common questions
What are the first signs of damp in a house?
A musty smell that airing doesn't fix, black mould, peeling wallpaper or plaster, flaking paint, and damp patches or tide marks on internal walls. Seeing more than one of these is worth a survey.
How much should damp proofing cost?
It depends on the type and extent of the problem. Checkatrade's data puts the average cost in Ammanford at £1,400, with most jobs between £962 and £2,076. Our cost guide breaks this down by job type.
Is it illegal to sell a house with rising damp?
No, but it usually needs to be disclosed if it's known about, and it's one of the things a mortgage survey commonly flags. Sorting it before you list tends to be cheaper than a buyer renegotiating after their own survey finds it.
