I cannot fault anything about this company...from start to finish the customer service was better than expected, and the work was just great. Any niggles were sorted immediately and were only minor issues. Absolutely thrilled with the finished result. Its always a worry when you are carrying out an expensive job. The quote was very reasonable. Not the cheapest or the dearest. But the customer service from the start made me confident that this was the company to choose. Absolutely nothing negative to report. First class.
