What changes the price
Type of Damp
Rising damp often needs more extensive work than simple condensation issues, impacting the overall cost.
Severity and Extent
A small patch of damp will naturally cost less to treat than widespread problems across several rooms or walls.
Property Size
Larger properties or those with multiple affected areas will require more materials and labour, increasing costs.
Accessibility
Difficult to reach areas, like basements or tricky external walls, can add to the complexity and price of the job.
Additional Repairs
Often, damp proofing includes plastering or redecorating after the initial treatment, which will influence the final bill.

Questions people ask
What is rising damp?
Rising damp happens when moisture from the ground travels up through the walls of your home. It can leave a tide mark, peeling wallpaper, and a musty smell. Treatment usually involves installing a new damp proof course.
What is penetrating damp?
Penetrating damp occurs when water comes in from outside, often through cracks in walls, faulty gutters, or damaged roofing. Fixing this often means repairing the exterior of your property. It is important to address quickly.
How is condensation treated?
Condensation is caused by excess moisture in the air settling on cold surfaces. Treatment can range from improving ventilation with extractor fans to installing whole house ventilation systems. It is the easiest form of damp to tackle.
How long does damp proofing last?
Properly installed damp proofing, especially for rising damp, should last for many decades, often coming with a long term guarantee. The durability of repairs for penetrating damp depends on the quality of the external repair work.
Should I get multiple quotes?
Absolutely, getting a few quotes is always a good idea. This helps you compare prices, understand the proposed solutions, and choose the best value for your specific damp problem. CertifySpace makes this easy for you.
Will damp proofing cause disruption?
Some disruption is normal, especially for rising damp treatments which might involve removing plaster and drilling walls. However, reputable firms will aim to minimise inconvenience. They will explain the process clearly before starting work.
