Damp Proofing Cost Calculator

There are three main types: rising damp (moisture rising up from the ground through walls), penetrating damp (water entering through external walls, roofs, or windows), and condensation (moisture from inside the home settling on cold surfaces). Each type requires a different treatment approach.

Rising damp DPC injection typically takes 1-2 days per wall, plus drying time of 6-12 months before replastering. Penetrating damp repairs vary depending on the source but usually take 2-5 days. Condensation solutions such as ventilation installation can often be completed in a single day.

Yes, professional damp proofing treatments typically come with a guarantee of 20-30 years for DPC injection and 10-20 years for other treatments. All Well Property Services provides a written guarantee on all damp proofing work, and we use only PCA-approved products and methods.
