10 Damp proofing and part plaster.
Posted 30 November 2025
Excellent service once again. I have used this company a number of times and I am never disappointed. The price given is the price you pay. The team arrives early and always take great care to make sure everything is covered and clean continually to keep the dust at bay as much as possible. The work is to a very high standard and I would not hesitate to recommend them. The guys never stop and I cannot praise them enough. John went over and above to help me on this occasion and I am very grateful.Verified reviewerJob location: NE3110 Fantastic workmanship

10 out of 10. John and his 2 sons did a fabulous job on the damp course treatment. John fully explained what work would be carried out and gave me a quote which I felt was very reasonable. I would highly recommend. He hoovered up, and my floor was mopped, everything was left spotless.Verified reviewerJob location: SR410 Highly recommend

John and his son arrived as arranged and did a professional and very tidy job of damp proofing two of our rooms. They were excellent tradesmen and did a very thorough job at a very reasonable price. We were very pleased with the way they tided up after them too. Would highly recommend.Verified reviewerJob location: DH5
