Plastering- 20 Jul 2026
Ryan did a fantastic job of plastering our 6 ceilings (covering over artex). I am really pleased with his work and he was an absolute pleasure to have working in the house. He turned up on time each day, worked ridiculously hard and left everything clean and tidy at the end of each day. I would highly recommend Ryan and would gladly get him back to do more work here in the future.

Plastering- 30 Jan 2019
Ryan was very prompt in responding to my request for a quote, arranging a visit the following day. However, in the meantime a friend who is a qualified plasterer offered to complete the job and hence I telephone Ryan to inform him of this decision and cancel his visit for quoting the job. Ryan was very polite despite the disappointment and I would recommend him to others to obtain job quotes.

Steve built an insulated, wooden-framed workshop/studio for us in our garden. We are delighted with the final result which is attractive and well finished despite being built to a tight budget. Steve is extremely knowledgeable, experienced and professional with impressive skills both practically and as a project manager. A real strength was his ability to listen, and respond, to what we wanted. We found him flexible and considerate, keeping mess to a minimum and communicating well with us throughout. He took a pride in his work and was completely honest and trustworthy. Our project was completed on time and within budget. We would definitely ask stteve to do work for us again and would recommend him to friends.
