Ryann and his team first completed a multiple room ground floor extension for us, including the installation of a new kitchen and bathroom. We were so pleased with the work that we asked him to build an outdoor garden room from scratch and completely refurbish our other bathrooms. We have always found Ryann to be friendly, punctual, knowledgeable and honest and I am more than happy to give my recommendation.

Pat was a pleasure to deal with from beginning to end he had everything covered and made the whole project a seamless experience. He provided me with a professional quote and had the patience to deal with my questions. He started the project on time svd no thing was too much trouble, when I needed a roofer to fix some issues with a leak he had someone on the job within a day. He handled every aspect of my garage conversion effortlessly and had the job finished on time right before Xmas. Would 100% use Pat again. Great guy who also knows good trades people. Thanks Pat.

Joinery & Cabinet Making- 23 Oct 2023
I was excited about working with Josh as he had such great feedback from other clients, and he did not disappoint. Excellent communication right from the off and very clear about what was involved, so was able to provide a detailed quote all of which made sense. He thought through what was needed in advance so there were no surprises or delays on the day. His price was reasonable although I’d have been happy to pay a bit over the odds for someone who didn’t mess me around, as has sadly so often been my experience in the past. He arrived on time to do the work, did it, cleaned up - and even did a few extra little jobs for me around the house (putting up shelves and a guitar hanger) while waiting for the paint to dry. A lovely guy, clearly skilled at what he does, and definitely someone I’ll be calling on again. Don’t hesitate to hire him!
