  • Damp proofing and plastering

    10Verified Review

    I've had a damp course done in the entire downstairs (2 front rooms, dining room and kitchen) of my terraced house in Roath as well as the plastering. Couldn't be happier with the work done by Lucas and Gaz! Both really polite and tidy as well. If I had any more work to be done, I'd have no hesitation going back to Damp Defence, Jade was extremely helpful and punctual on attendance to first inspect the jobs and Sam was great with very small issue due to shrinkage after front rooms were done. Would highly recommend Damp Defence as a company to do this work!!

  • Damp proofing a garage conversion

    10Verified Review

    After a really bad experience with a building company that did a garage conversion we were worried about getting another company in to do the damp proofing that should have been done. However, right from the initial phone call to Damp Defence it has been a smooth and easy process. The quote was very reasonable, the communication was excellent going in to it and answering our questions and the job was done quickly and with very minimal disruption. We are very happy with the work carried out and will be recommending them to anyone that needs damp proofing and would happily use them again.

  • Definitely recommend


    I would definitely recommend Damp Defence, Jade was very helpful in answering all of my queries and very quick to respond. Sam's workmanship is excellent, he was very courteous, on time and cleared up after himself. It was a pleasure to do business with the company and I will definitely use again if I experience any other damp issues.

  • Damp Course on external wall

    10Verified Review

    I cannot sing the praises of Damp Defence enough. Jade came to do the quote and she was very knowledgeable, friendly and honest about the situation with our walls. Sam came to do the work, he went through the questions and concerns we had, he just got on with everything and did an absolutely amazing job. He cleaned up everyday, and took the rubbish with him. We asked him to do something extra and he did with no hesitation. The quote was very reasonable, and there were no hidden suprises when we got the bill. I would highly recomnend them and would certainly use again.
