Alin from Home Improvements Specialist Ltd responded promptly and professionally to my insurance-related repair job. He arranged a viewing with the resident, kept me copied on all communications, and delivered a compliant PDF quotation without delay. Though the claim is still under review, I intend to award him the job once approved. Highly recommend for his reliability and attention to detail.

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.
