About Perma-fix Limited

In 2012, my ex-employers retired, and this gave me the impetus to start my own company. All of my tradesmen, I have known for many years, they are all highly professional. I have the technical back up of some of the country's leading experts. I have been installing cavity wall ties for over 28 years, I have installed many 1000's of ties, and come across many different problems. Like wise with the damp proofing timber treatment and basement conversions . As a team we have lots of hands on experience.
We cover Hampshire, Surrey and London

Latest reviews

  • Repair damp damaged flooring

    Great communication throughout, excellent time keeping (which seems to be a rarity these days), high standard of work.

  • Installation of a new injected chemical damp proof

    Great job, fair price, good communication and everything left clean and tidy.

  • Damp proofing - dry rot & rotted skirting board.

    Permafix have been an absolutely brilliant company & extremely helpful service from their staff (especially Debbie who is always there to answer my questions). When other companies did not take me seriously at ALL because I was only in the process of buying the property, Permafix helped me in deciding the best solution.
    I would highly recommend Permafix.
