Can’t fault our experience from start to finish. We were kept informed throughout. Lovely to deal with a family business. The fitters were polite, hardworking and very neat. We’re overjoyed with our new composite door. Thank youLisa woodburnOctober 12, 2021
We had an excellent experience from start to finish using Sapphire Windows. Nothing was too much trouble; they even picked up the cat flap that we wanted installed in the front door. The work was carried out in only one day and the installers were polite, professional and cleaned up after themselves. We are absolutely overjoyed with the end result and would not hesitate to recommend.Lois HarrisOctober 11, 2021
A professional bi-fold door installation at a competitive price. Recommended.Gingetube68September 28, 2021
Great customer service, had some windows replaced previously, done a good job, now getting complete house done. Only issue with getting materials so currently lead times are very long.Adam ShabberSeptember 20, 2021
Excellent service all round. The gentleman that came to measure up had great experience and offered us advice on which windows would look best and be most practical for that particular room. From the initial phone call through to competition was a 2 month turn around. The window fitters were professional and left no mess and worked around us while we were working from home. Couldn’t recommend this company more.Thomas BartlettAugust 20, 2021
Excellent family business. All staff are courteous, polite and professional. Over the moon with our new windows. Will be using again in the near future.Jan BowenAugust 19, 2021
This company is family run, and this is reflected in the service that you receive. Every step of the way is clear and honest and they are contactable with any queries. On installation day, they were on time and worked efficiency with no fuss. The door was amazing and far beyond our expectations. They were very tidy (Welsh and normal definition) and a pleasure to have working in our house. Would we have this company again? Definitely.TeddyEdw00dApril 28, 2021

absolutely delighted from the very beginning, love our new door , diolch ichi gyd am popeth. would definitely recommend .Non QuigleyMarch 16, 2020
Excellent value for money. Cheapest out of 3 quotes we had, but without compromising quality. The installation team were amazing. Had some problems fitting the new door frame through the house so they went up over the garage roof. The patio door looks absolutely fantastic and the boys left the house looking so clean and tidy. The floor and walls around the old door looked a bit shabby but it all looks so neat now. Fabulous job!Laura MorrisMarch 14, 2020

We needed a lock repair and some replacement windows. The original supplier just kept saying they were too busy. We contacted Sapphire and received a friendly and prompt response. Everything is now sorted. We are very pleased with the service.Gill and Peter MuddJanuary 10, 2020
We had a composite door installed by Sapphire Windows before Christmas. The service from quote to install was superb. We visited their showroom before making our choice, they have a number of doors and colours on display, which helped us make our decision. We’re over the moon with our new door and will be recommending Sapphire to anyone that asks.Karen WilliamsJanuary 9, 2020

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.

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

Trevor SaundersMay 14, 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
Very helpful and friendly staff. Window and door fitted quickly. The fitters were also friendly and very neat and tidy. Reasonably priced. Happy customers.EMMA AUEFebruary 14, 2019

Excellent service from beginning to end. I received the best customer service. They were very accommodating and flexible around my working hours which resulted in minimum fuss throughout. Great communication, I was notified every step of the way. I am extremely happy with the customer service, quality of the window and door I ordered and also the quality of the installation. Highly recommend this company and will definitely be using them in the near future. Thank you.Rachel MilesFebruary 12, 2019
