Frequently Asked Questions
- What are the different types of damp?
- The three main types are rising damp, which comes up from the ground; penetrating damp, which enters through walls or roofs; and condensation, caused by excess moisture in the air. Each requires a different treatment approach.
- How can I tell if my house has a damp problem?
- Common signs include peeling wallpaper, black mould, a musty smell, salt deposits on walls, and damp patches that feel cold to the touch. We offer a free inspection to diagnose the cause and recommend the right fix.
- Do you offer a guarantee on damp proofing work?
- Yes, all our damp proofing treatments come with a long-term guarantee. The length depends on the type of treatment carried out, and we provide full details in writing before work starts.
