    Fantastic work

    Posted 12 February

    Dave was very thorough when he came to give me a quote. His team arrived promptly on the first day and had it all completed within 3 days. The work has been completed to a very high standard, you cant tell that there has been any damp issues there previously (i.e a line in the wall where its been hacked off and redone). They were clean, polite and efficient. I would definitely use them again for any future works required.

    Excellent work from DP Preservations

    Posted 12 December 2025

    Had a major damp problem in the front room of my house, got in contact with Dave at DP Preservations as I've used them before and was extremely happy with the work done. I received a detailed report of what the issue was and how they would deal with it, this was followed up by a quote with a breakdown of the work along with pricing and the start date. The work itself took 4 days and the DP Preservations team were professional throughout not only in the work they did but also their cleanliness and communication. The job was finished on time with zero issues, I can't recommend them enough.
