  • Great job

    10Verified Review

    We couldn't be happier with the work Joseph and his team did. From start to finish, Joseph was very clear and helpful in explaining what was needed to be done and how his team would approach the team. A top team that we'd happily use again.

  • Faultless work.

    10Verified Review

    I cannot fault this company. They made a thorough assessment of the cause of the damp ingress and carried out the remedial work with expertise, efficiency, professionalism, and courtesy throughout. This is a high quality, no bullshit team and whats more their charges were very reasonable - in fact less than half the costs estimated by a separate "specialist" damp-proofing company. I have no hesitation recommending them and would gladly take them on again should the need arise - which I hope it doesnt!

  • A very helpful visit

    10Verified Review

    Joseph visited us quickly and inspected our damp problem. He decided that there was no work that he needed to do, but gave us advice on how to deal with the problem ourselves. Altogether a fruitless visit for him, but he was very helpful to us, for which we are grateful.

Company info

I founded Trident damp in 2009, we carry out professional damp and timber surveys for house purchases with honest appraisals as can be seen in our ratings.

I have personally worked for damp companies as an operative and surveyor for the best part of 40 years. This has given me a great insight to the damp and wood remedial problems that do arise, we also carry out roofing and guttering repairs with our own roofing expert.

Having first-hand knowledge, I also give advice on problems through our website 

We are approved contractors with Triton systems and offer a full range of damp and wood remedial treatments we are also which trusted traders.

Our guarantees can be insurance backed which makes them bank and building society approved. 
We have over 400 reviews and feedback from various sites which can be found on our website and have a great reputation in the industry.
