  • I have been a customer of this company for many years and they are consistently good. The visits to assess and measure requirements are done quickly and the supply and fitting done very efficiently. When I did have an issue with misaligned decorative leading in one of my units, the matter was dealt with very quickly and fuss free. The fitters are always polite and knowledgeable and leave the place tidy after the job. I find the product is good value for money. I would happily recommend them.
