Does dry lining stop damp?

Short answer: Dry lining does not stop damp on its own. It can hide stained or damaged walls temporarily, but the moisture may continue behind the plasterboard and cause mould, unpleasant smells, damaged insulation or decaying materials. The source of the damp must be identified and repaired before dry lining begins. Possible causes include leaking pipes, damaged gutters, poor external pointing, rising damp, penetrating rainwater and inadequate ventilation. Moisture-resistant plasterboard can cope better with humid conditions, but it is not waterproof and cannot prevent water entering a wall. Some properties may require a specialist membrane, ventilated cavity or damp-proofing system. Once the cause has been resolved and the wall has dried, dry lining can provide a clean and practical new finish.

Helpful context

The key is to choose the right board and build-up for moisture, ventilation, and insulation, so you avoid hidden problems later.

For a proper quote, we will look at wall condition, moisture, access, insulation, and the finish you want. That keeps the price accurate and avoids surprises later.
