Delighted with everything from initial meeting to fitting. The customer service from sapphire windows was fantastic from the start – even when I needed to change the fitting date at short notice. The windows and doors are great quality and the fitting was done to a high standard including the finishing.

I’ve used Sapphire Windows for all my doors, windows and a conservatory, all of these have been really excellent, they have done this work over several years and each time has been fantastic from the quotes and pricing to the quality of the windows they make and with the fitting. They are all lovely hardworking people and it is great that they are a family run business. Everything has always been brilliantly fitted, everything cleared away at the end and everything is always absolutely perfect when finished. I’m always thrilled when they have been here and I do reccomend Sapphire to everyone and anyone who visits comments on how brilliant the Windows etc are with me. Thanks everyone at Sapphire, you’re all brilliant!Helena ReesJuly 12, 2019

From the moment we discussed our requirements with Russell, we knew we were in safe hands. He was so patient and nothing was too much trouble. We were replacing three windows in all, the lounge 12ft long with triple glazed. As the windows had been in for about 35years I was concerned that the window reveals would be damaged. I need not have worried. The workmen Wayne and Dale were absolutely fantastic, quiet, polite and clean and worked diligently all day, we were so impressed by them both. They made light work of installing the frames and glass with no damage whatsoever, the windows look fab.and I would not hesitate in going to them again. Russell and his son Shaun were a pleasure to deal with and as a local firm they have done us proud. Diolch o galon.Sian ThomasMay 13, 2019
I cannot praise this company highly enough. Very high quality product delivered well ahead of forecast date and everyone involved from showroom staff to company owner to fitters has been an absolute delight to deal with. I am somewhat fussy in regard to understanding full specifications of product and I wanted high quality- all of my questions were answered in detail and the product is superb.Carol WhitlowMarch 22, 2019
Deciding to buy a composite front door I researched manufacturers then visited local installers. Following a visit to their Ammanford showroom I took a trip to the workshops of Sapphire Windows. Impressed by the set up, I learned from partner in the business, Shaun, how Sapphire is a long established family business. It soon became clear Shaun was very enthusiastic and knowledgeable in regard to product. I arranged for a visit and quote. When Russell arrived ( Shaun’s Father) I discovered his experience in the business spanned 30 years. Like father, like son a real pleasure to talk to. We had a reassuring chat over the various designs and manufacturers, without any sales spiel. Today my new door has been fitted. The fitters were excellent, polite, tidy, professional. My new door looks stunning, as well as being solid and secure it has transformed the look of our home. If you are considering new doors or windows, I can highly recommend Sapphire Windows.Dave AlexanderMarch 8, 2019
