Frequently asked questions
What are the signs of damp in a house?
Look for: tide marks on lower walls, peeling wallpaper or paint at low level, white salt deposits (efflorescence) on plasterwork, mould growth on walls or in corners, a musty smell, staining on ceilings (often a plumbing leak above), or black mould in cold corners (condensation).
What is the difference between rising damp, penetrating damp and condensation?
Rising damp comes up from the ground through masonry (shows as a tide mark, typically 0.5–1m high). Penetrating damp comes through walls, windows or roof defects. Condensation (the most common cause of mould) forms on cold surfaces when moisture in the air meets them. Each has a different fix.
How much does damp proofing cost?
Chemical DPC injection for a typical party wall or external wall costs £500–£1,500. A full damp survey, treatment and re-plastering for a ground floor room runs £2,000–£5,000. Basement tanking starts at £3,000 and rises with size and water pressure.
Do I need a specialist damp survey before getting work done?
An independent RICS-qualified surveyor or PCA (Property Care Association) member is advisable for significant damp problems. Be cautious of free surveys offered by damp treatment companies — they have an incentive to recommend treatment even when the solution is simply improving ventilation or fixing a leaking gutter.
Can damp be fixed without re-plastering?
In some cases yes — if the source is external (leaking gutter, defective pointing) and the plaster is intact, fixing the source and allowing to dry is sufficient. For most rising damp treatments and any penetrating damp that has saturated the plaster, re-plastering with salt-resistant renovating plaster is required.
Does damp proofing come with a guarantee?
Reputable PCA member companies typically offer 20–30 year guarantees on chemical DPC injection work. Check that the guarantee is insurance-backed (valid even if the company ceases trading). Always read the small print — guarantees often exclude damage from new leaks, structural movement or inadequate ventilation.
