About Alan Johnson

I have been in the building trade for over 30 years, and have lots of experience. we specialise in. Damp proofing woodworm treatment dry wet rot. Basement conversions Our damp proofing work comes with 30 year guarantee which is underwritten by Triton systems Garage conversions. Even though it comes under permitted development building regs are required it's a simple application to do you dont need drawings. we can guide you through it. building regs insist all external walls have to be damp proofed to stop penetrating damp and solid floors need a new membrane down. There is no need for the big expense to dig up the floor our tanking slurry acts as a membrane leaving you money to spend elsewhere. That's were our damp proofing skills come in. Flat roofing Rubber or Felt you can see some of our past projects below the high level of workmanship. Flat roofing as 20 years for rubber and felt as 10 years which is underwritten by materials suppliers.

Fantastic service and great price. Quick to come out and quote on damp course and tanking in cellar. Very honest, explained things well and quoted a great price there and then. Didn’t tutt and tell me how bad everything was or that extra needed doing etc. Turned up when he said he would and was done in the time estimated. Alan and his colleagues were all very friendly and polite. It was honestly a pleasure having them do this job. So far I am hugely impressed with the work and I would definitely recommend!

Very proactive. I got a very quick response on a Sunday morning via email and text, which was brilliant as I was hoping for a quick reply but never expected one on a Sunday! Got the report done very quickly too which helped me to knock money off the purchase price of the house we were buying in light of the damp report.
