    Excellent damp proof company

    Posted 07 January

    Jonathan and his team were great from start to finish. Jonathan is extremely thorough and identified all the issues that needed addressing (unlike the builder who had allegedly dealt with the problem previously). The work he did was carried out to an extremely high standard and he updated me with messages and videos every day. At the end of the job, the room was spotless despite the extensive work carried out. I highly recommend him and his team.

    Excellent service from JKA Damp Proofing & Plastering

    Posted 03 December 2025

    We have recently had three areas of damp that have been tackled by Jonathan who runs JKA Damp Proofing & Plastering. In each case there was a different cause of damp. Jonathan diagnosed the causes and then fixed them with great professionalism, explaining his work as he went along. He prepped the areas beforehand with great precision, carried out the work to the highest standard and cleaned up meticulously afterwards. We are absolutely delighted with the repairs and would wholeheartedly recommend him if you have problems with damp.

    Damp Proofing and New Drainage

    Posted 09 November 2025

    JKA were professional and good at communicating what needed doing and carried out the work in an efficient and tidy manner. They explained clearly what needed doing and did some unrelated work in the house that was really appreciated. They are very proud of the quality of their work.

    SIKA1 Exterior Waterproof Rendering

    Posted 07 November 2025

    I previously called Jon to do some interior damproofing to the porch at home. That was expertly done, so I didn't hesitate to ask him to take on some challenging damproofing to exterior walls in the back garden. This was done to a very high standard. I have jobs at my mother's house to come! I really recommend Jon!

    This is the second time I've used JKA Damp Proofing & Plastering. That probably says enough but they do a great job, tidy and clean while working and work hard!

    JKA Damproofing did a fantastic job resolving our damp issue. From the outset, Jonathan was highly professional, clearly explaining what needed to be done. The work was carried out efficiently, and the kitchen was left spotless upon completion.
