Ian came round to take a look at a damp patch that had started showing up on one of the utility room walls. He turned up on time, was really friendly, and clearly knew what he was talking about. He gave everything a proper check over and explained what was likely going on in a way that actually made sense. He didn’t try to make a mountain out of a molehill or push for any unnecessary work—just gave honest, practical advice on what to do next. Really appreciated how straightforward and helpful he was.

Carl and his team did a fantastic job when working on my garage extension and conversion project. It was the first time that I’ve ever done this type of thing but Carl’s communication was spot on from start to finish. He was courteous and communicative throughout and talked me through each day where the project was at and what was next. If I had to appoint a builder again for whatever reason I wouldn’t hesitate in appointing Martin Building Ltd to complete the job. Thanks again Carl!

This review is way overdue. Kev, Mick and Dave did a fantastic job of our kitchen extension and garden landscaping. Has really transformed our home. We can not recommend them enough, Kev pointed us in the right direction the whole way through even making suggestions which saved us thousands. He reused materials, which also saved us more money and pulled out all the stops to ensure we had a working kitchen in time for lockdown.

Chris and John and crew were hard working and brilliant. They turned up on time and made light work of putting in double steels making sure everything was done. When building control requested added work, they had no problems getting it sorted. Hard working team cleaned up each evening. Great job. Price was reasonable.
