“It was a large job over 100k involving two extensions, loft, total rewiring, bathroom and plumbing, garden and carpentry work. The builders did the work quickly keeping the disruption to us as little as they could, were the quickest to respond to any queries or problems I've ever experienced, and did a great job. We are now loving our reworked house!”
