How to Choose a Damp Proofing Company: 7 Things to Check

Damp proofing is an industry with a mixed reputation. High-pressure sales tactics, unnecessary treatments, and poor workmanship are unfortunately common. Here's how to protect yourself.

1. Are They Recommending a Survey First?

Any legitimate damp proofing company will want to carry out a thorough survey before recommending treatment. If they give you a quote for rising damp treatment over the phone without seeing the property, walk away.

2. Do They Diagnose the Type of Damp Correctly?

The treatment for condensation, rising damp, and penetrating damp are completely different. A company that recommends rising damp treatment for what is obviously condensation is either incompetent or dishonest.

3. Are They Insured?

Ask for proof of public liability insurance. Reputable tradespeople carry it as standard.

4. Do They Provide a Written Guarantee?

Chemical DPC injections and structural waterproofing systems should come with a written guarantee. Make sure it covers both materials and workmanship.

5. Can They Provide References?

Ask for references from similar jobs in your area. Reputable companies should have no hesitation providing these.

6. Are They Members of a Trade Body?

Membership of the Property Care Association (PCA) or the Damp and Timber Preservation Association indicates a certain level of professional standards.

7. Is the Quote Itemised?

A professional quote should break down the cost of survey, materials, labour, and any associated work such as replastering.
