What Sets Our Windows Apart?
  • We manufacture our own windows. All our products are made to measure, they’ll be expertly fabricated by our master craftsmen, using the latest cutting edge machinery at our factory in Ammanford, Carmarthenshire. We don't buy an entry level trade window.
  • Huge choice of colours. For a more traditional look wood grain foil laminates are available. Whether its vibrant Golden Oak or rich Rosewood, the effect is a solid, satisfying, realistic appearance that belies the technology and performance hidden beneath. However if a wood grain or white window isn’t what you desire, we have a range of colours to suit every pallet.
  • Choice of windows styles to suit any property. Our Traditional chamfered window, with it's effective yet gentle chamfered design looks sharp and stays that way with no nooks or crannies for dirt to collect. Or our Heritage Flush sash window is a perfect choice for traditional or contemporary homes alike. Designed to replicate a traditional timber window, the products’s subtle charm and elegance transforms a building like no other.
  • Our windows are stronger as we use a 70mm frame. An increased width of 70mm actually allows the profile to be narrower (reducing the sightlines) whilst improving on the high levels of structural and insulating performance. Incidentally, a 70mm width also means that paint lines and mastic residue from previous windows can be fully covered.
  • By using the very best uPVC profile & hardware we are able to offer the most secure windows. Our windows have attained BS7950 and PAS 24 security product standards.
  • Our windows achieve the best thermal performance. By using a 70mm frame & high performing thermal glass our windows far exceed the thermal performance required by building regulations. We only offer the best A rated window as standard.
  • For our weather climate, superior weather performance is important. Our windows are tested to the latest European standards for water ingress, air permeability and wind resistance. Air Permeability EN1026, Water Tightness EN1027, Wind Resistance EN 12211.
  • We use a neutral grey colour for the seals and gaskets of our white windows. Where other windows on the market will use black seals. We believe that a traditional black gasket on white framing would have broken the smooth lines of our window design.
Why Choose uPVC?

uPVC windows are an ideal choice when considering replacement windows. They require little maintenance in comparison to their timber counterparts. They are easy to clean. By far the most energy-efficient option in comparison to other material choices. And thanks to massive improvements in aesthetics, build quality, and energy efficiency, they compliment any property.

Our team of design consultants can visit you at your home to discuss your requirements if you are thinking about new uPVC windows. Or if you wish to see our range of high-quality windows, you can visit us at our showrooms where we can explore our ranges with you.

Customer Testimonials - 100% 5 Star Reviews online

We are very happy with our new door. Excellent quality, professional staff and great service.Eva PriedeSeptember 12, 2022
Sapphire replaced a very old window with new and fitted a new door. We were given good choices in style, colour etc. and the results are excellent. The team were professional, engaged, courteous and tidy. They worked hard to ensure the job was perfect. Impressive and highly recommended. Probably the best value around.Wendy RaynerAugust 17, 2022
Sapphire Windows installed new windows for my grandmother. She thought the service was excellent, the workers were very pleasant and left the house spotless during and after the work. The quote was extremely reasonable considering the high standard of work completed and she would highly recommend.Siôn JonesAugust 14, 2022
We contacted Sapphire Windows for a quote. The owner came to do a rough measure up at a time that suited us. Then we were sent a quote, which was very competitive, so we didn’t bother with any other quotes. From previous experience of hard sell tactics with other companies, we had been dreading going through this process. The surveyor came to do a precise measure – all 11 windows were different sizes. It took a while for actual fitting but each window is made to order. The team that did the fitting were very professional. No mess. The windows are absolutely fantastic!!! Such good quality. Now a few months after fitting, we’re so happy with the whole experience.Lynnette GarrettJuly 20, 2022
Not the cheapest of the three quotes I got but by far the most professional company and realistic about timescales. There was a slight delay due to current circumstances beyond their control, but I was kept well informed as to progress and once ready fitting was arranged for a date to suit me. Windows are all manufactured to order and are of excellent quality. Fitters were careful, thorough and very polite. I would thoroughly recommend.Jane NicholasApril 1, 2022
This company has been a pleasure to deal with. Great service from the office staff and the installers were wonderful, very polite and clean. Happy we chose Sapphire and will be recommending to family and friends for sure.Mary SinclairFebruary 17, 2022

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
Very pleased with the end result, quick response, fitters were excellent too.Claire NethertonMarch 9, 2020

Excellent communication and lovely staff. We had the door quicker than expected, it was fitted promply and professionally with no hassle. From start to finish we had 3 appointments and each one of the three different staff members arrived on time. We love the door and have already had compliments from neighbours. We’d highly recommend Sapphire, thank you very much.Laura JonesFebruary 24, 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. The windows and doors are great quality and the fitting was done to a high standard including the finishing.

Pauline BlacktoppAugust 12, 2019
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
Extremely pleased with our new windows and doors. Sapphire gave us a very competitive quote for a high quality product. Russell and Shaun were very approachable and answered all the queries we had and the fitters (Wayne and Dale) were professional, friendly and efficient. Would DEFINITELY recommend Sapphire Windows .Howard FrancisFebruary 14, 2019
