Moisture from the ground rises through walls by capillary action. Common in older properties without a damp proof course (DPC) or where the DPC has failed. Look for tide marks, peeling wallpaper, and salt deposits at the base of walls (typically up to 1 metre high).
Water enters through external walls, usually from rain, leaking gutters, or defective pointing. Shows as damp patches that worsen during heavy rain. Common causes include cracked render, failed mortar joints, and bridged cavity walls.
The most common form of damp in UK homes. Warm moist air meets cold surfaces, creating water droplets and black mould. Worst in bathrooms, kitchens, and bedrooms. Improved ventilation and insulation are the primary solutions.

Damp proofing is the treatment and prevention of moisture problems in buildings. This includes installing or repairing damp proof courses (DPC), waterproofing basements, treating rising and penetrating damp, and managing condensation. Professional damp proofing protects your property's structure, prevents mould growth, and maintains a healthy living environment.
Common signs include damp patches on walls, peeling paint or wallpaper, a musty smell, visible mould, salt deposits on walls, and condensation on windows. If you notice any of these, a professional damp survey (typically £150–£350) will identify the cause and recommend treatment.
Costs vary by treatment type: rising damp treatment (DPC injection) costs £800–£2,500 for a typical house, penetrating damp repair costs £500–£2,000, and basement tanking costs £2,000–£6,000. A damp survey costs £150–£350. Prices depend on property size, severity, and location.
The Property Care Association (PCA) is the UK's leading trade body for damp proofing, woodworm treatment, and structural waterproofing. PCA members must meet strict quality standards, carry appropriate insurance, and offer insurance-backed guarantees. Choosing a PCA member gives you confidence in the quality of work.
Minor condensation can be managed with improved ventilation, dehumidifiers, and anti-mould paint. However, rising damp and penetrating damp require professional treatment — DIY damp proof courses rarely work and can mask underlying structural issues. Always get a professional survey before attempting treatment.
