“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.”

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 8 years on the register also points to an established business rather than a brand-new one.
