What moves the price
- Type of treatment required — a damp proof membrane or tanking costs more than injecting a new damp course.
- Size of the property — a larger affected area means more wall to strip, treat and replaster.
- Complexity of the damp issues present — a mix of rising and penetrating damp needs separate treatments, each adding to the price.
- Hard-to-reach areas — damp behind fitted units or under floors takes longer to reach and treat.

How to pay less
- Fixing leaking gutters or downpipes early can stop penetrating damp before it needs a full damp treatment.
- Asking whether better ventilation could solve condensation can save paying for a fuller damp treatment.
- You can ask the damp proofing specialist to compare treatments, as a surface treatment may cost less than a new membrane.
- Treating only the walls an inspection shows are affected, rather than the whole floor, keeps the damp proofing job smaller.
Before you book

- Information on any previous damp issues or treatments.
- Clearance of furniture and belongings from affected areas.
- Details of any visible signs of damp or mould.
- You can ask whether the damp proofing specialist is qualified to diagnose the type of damp before recommending any treatment.
