A nice and tidy builder who explained my options, discussed how best I could save money and then did a totally brilliant job. He said a happy customer might want another job done and he is dead right. What a refreshing attitude to have a great job.

I found Jason on this website and made contact with him after reading the reviews. He got back to me straight away, was courteous and super helpful, and came round to look at the work and give me a quote. Because he is understandably popular he couldn’t start my work for 3 months, but he gave me an exact date he could start the work and he stuck to it. He also quoted me for everything upfront, and always stuck to budget. He was very honest and told me if he didn’t think something was necessary, and also helpfully pointed out a few things I hadn’t noticed that were necessary. I left my house keys out for Jason each day (I was at work) as I knew I could trust him completely. He went above and beyond to kindly help me with a couple of extra things that popped up whilst he was at mine doing the agreed work. He knows about everything, particularly ventilation and damp. I cannot recommend him highly enough, and will be calling him again in the future for anything else I need! Top bloke, and great to chat to as well! Things he did for get included.. - resurfacing a flat roof (resin paint) - new guttering - new airbricks - installed a ventilation system - got scaffolding up and resealed a leaking chimney plus painted the side of the house with storm dry - sorted out a huge crack in my chimney breast & rendered it after too Many other jobs on my shopping list of issues too. Jason is great, drop him an email 👍

I recently had Jason carry out work at my home to install a damp proof course where none previously existed, and I couldn’t be more impressed with the results. From start to finish, Jason demonstrated exceptional knowledge and truly outstanding workmanship. He arrived promptly each day and worked exactly to the agreed schedule, which gave me complete confidence in the project. His pricing was very competitive, and the quality of his work far exceeded expectations. Jason was courteous, professional, and respectful throughout, always ensuring the house was cleaned and tidied at the end of each day. What really stood out was his integrity. During the job, he identified additional work that needed doing—something that wasn’t part of the original estimate—and he completed it without charging anything extra. That level of service is rare and hugely appreciated. I can wholeheartedly recommend Jason. His reliability, expertise, and commitment to doing the job properly make him an exceptional tradesman. I would not hesitate to hire him again.

Jason visited in late October and undertook the damp proofing work in early December. Turned up when he said he would, was courteous and polite. Did a very professional job - explained what he was doing and why. Was neat, clean and tidy. Apologised that he couldn’t get the perfect plaster finish due to the cramped space and the presence of pipes. When I looked - he’d done a fantastic job. Highly recommend Jason and a pleasure to do business with.

Jason and team recently installed an injected damp course and repointed some brickwork at my new home. Jason was courteous, professional, and did a great job. Jason took the time to take a through set of photos and videos of his work and even added some extra touches to ensure the house was fully watertight during his visit. What stuck out to me most was his genuine care and honesty, which can be in short supply these days. I would thoroughly recommend him to anyone and look forward to benefitting from his expertise again in the future.

Ventilation for a slightly damp cellar

I had a cellar that was a little to damp for our liking. Jason first gave a phone consultation and suggested one approach. Unfortunately that approach didn't work due to the setup of the house so he suggested an alternate plan to install two telescopic ventilators. These were installed within a couple of weeks at a very reasonable price. He and his son are great and I would highly recommend them.
