How to Prepare for Your Damp Proofing Service

A few simple steps to ensure you get the best experience:

  1. 1Do not repaint or cover damp areas before the survey β€” surveyors need to see the full extent
  2. 2Move furniture away from affected walls
  3. 3Note when the problem started and any patterns (worse in winter, after rain)
  4. 4Check gutters and drainage near affected areas

Frequently Asked Questions About Damp Proofing

How do I know if I have rising damp?

Rising damp shows as a tide mark up to 1 metre from the floor, with salting (white deposits), peeling paint, and wet plaster. A moisture meter survey will confirm it.

What is the difference between rising damp and penetrating damp?

Rising damp comes from ground moisture travelling up walls. Penetrating damp comes from external water entering through walls, roof, or openings. Each needs a different treatment.

How much does damp proofing cost?

Rising damp treatment typically costs Β£500–£2,000 per wall, including replastering. Basement waterproofing is more expensive, typically Β£3,000–£15,000 depending on the system.

Is mould always caused by damp?

Not always. Mould is often caused by condensation from poor ventilation β€” especially in kitchens and bathrooms. A proper survey will identify whether it is condensation, rising damp, or penetrating damp.
