    David and his team really helped me out by rescheduling this treatment at short notice. Helpful, friendly and professional. I'll be asking them back to do further damp proofing work. Thanks so much David.

  • Damp proofing of two small rooms

    10Verified Review

    David and his team did a fantastic job at short notice to remedy some damp issues to 2 of our bedrooms. The survey highlighted the cause of the issue and he was able to put together a plan in short order. They fitted a membrane and skimed the rooms throughout for a great finish and did this prior to the target date. He gave great advise to prep the areas ready for the work and we are really happy with the end result. We would definitely recommend them, great job and friendly team

  • Replaced flooring in utility room


    The floor and supporting joists were badly damaged from a leak from the washing machine. Perma-Fix conducted a survey and sent us a competitive quote. A week later Perma-fix fitted us in to their busy schedule which we were most grateful for. On the day 2 fitters arrived early and worked conscientiously throughout the day. It was a difficult job as the washing machine, WC and wash basin had to be removed. They were conscientious, polite and clean and we were very pleased with their work. I would highly recommend them again.

    Thai was the second time that we have used Perma-Fix to undertake some necessary damp proofing work in our house. Once again a potentially very noisy, messy and diasruptive job was completed efficiently and cleanly, with the minimum of pain for us! Excellent workmanship and courteous service from start to finish.
