I used Sheerwater Glass twice: several years ago when we did our house renovation and most recently for our garden outbuild. We bought our windows and doors there. I can't compliment this company enough. On both projects, they impressed us. Firstly the people there are amazing - very professional and responsive. I didn't chase them for anything. And they gave us excellent pieces of advice along the way. Mark, Nic, Claire, Chris, Stuart and the rest of the Team, you are incredible! Secondly, the product is of very high quality. Not many companies offer uPVC windows which are almost as sleek as aluminum! And in case you do have any problem (e.g. one of our window keys stopped turning properly), it is very easy to book the aftercare service and at no cost! Last but not least is the price. Of course, we shopped around on both occasions and both times Sheerwater Glass were the best value. And with our most recent project, the company has shown incredible flexibility and customer service. I would definitely recommend Sheerwater Glass and we would use them again and again.
