Manufacturing Premium uPVC Windows & Doors in Carmarthenshire
Unlike many window companies, here at Sapphire Windows & Doors, we manufacture our own uPVC windows and doors at our factory in Ammanford, Carmarthenshire.
By manufacturing in-house, we maintain complete control over quality, precision and sustainability from design through to installation.
Every window and door is made to measure using modern manufacturing technology, premium materials and environmentally responsible production methods.
Our experienced surveyors carefully measure every property before fabrication begins, ensuring a perfect fit and outstanding performance for years to come.
Made by us. Installed by us. Built to last.
Premium Aluminium, Timber & Composite Doors from Trusted Partners
Alongside our own uPVC range, we work with carefully selected manufacturers who share our commitment to quality, innovation and sustainability.
Many of these premium products are available exclusively through Sapphire Windows & Doors across South West Wales, while others, such as Sunflex, are only offered by us throughout Wales. Homeowners can access exceptional products that are rarely found elsewhere, backed by Sapphire’s expert advice and installation.
Our trusted partners include:
- Sunflex UK – Premium aluminium windows, sliding doors and bifold doors.
- Bel’M – High-performance aluminium, AluSteel and timber entrance doors, with designs and finishes rarely available elsewhere in Wales.
- Gerda – Award-winning premium AluSteel front doors, available exclusively through Sapphire in South West Wales.
- Glyngary – Beautifully crafted timber windows and doors, combining traditional craftsmanship with modern performance.
- Distinction Doors – High-quality composite doors offering outstanding security, style and energy efficiency.

Every manufacturer has been carefully selected because they share our commitment to craftsmanship, innovation and sustainability.

Why choose Sapphire?
By partnering with leading manufacturers and offering exclusive product ranges, we’re able to bring homeowners across South and West Wales a collection of windows and doors that you simply won’t find with most local installers. It’s just one of the reasons homeowners travel from across Wales to visit our showrooms in Ammanford and Milford Haven.
Expert Installation by Our Sapphire Windows & Doors Team
The finest windows and doors deserve the finest installation. That’s why every installation is carried out exclusively by our own experienced Sapphire fitting teams – we never use subcontractors.
Every installer receives specialist training for the products they fit, whether it’s our own uPVC range or premium products from trusted partners such as Sunflex, Gerda, Bel’M, Glyngary, Distinction Doors and OTIF. This ensures every installation is completed to the highest standards, exactly as the manufacturer intended.
Unlike many companies that work to unrealistic daily targets, we don’t pressure our installers to fit a certain number of windows or doors each day. Instead, we encourage them to take the time needed to complete every installation with care, precision and meticulous attention to detail.
Quality should never be rushed.
Our installation teams take enormous pride in their workmanship and treat every home with the same care and respect they would their own. From carefully protecting your property to leaving every room clean and tidy at the end of each day, professionalism is at the heart of everything they do.
It’s one of the reasons we’re so proud of the hundreds of 5-star reviews we receive from homeowners across South and West Wales. Time and again, our customers praise the friendliness of our teams, their exceptional craftsmanship, their meticulous attention to detail and the cleanliness they leave behind.
At Sapphire Windows & Doors, we don’t believe in high-pressure sales. We don’t employ a traditional sales team because we believe every customer deserves honest advice and our best price from the very beginning. Once we’ve provided your quotation, we won’t chase you with repeated phone calls, emails or sales tactics. We’ll simply give you the time and space to make the decision that’s right for you. If and when you’re ready, we’ll be here to help.
From your initial survey through installation and aftercare, you’ll deal directly with the same trusted Sapphire team – experienced local professionals who genuinely care about delivering exceptional workmanship and outstanding customer service.
Because at Sapphire, we’re not just installing windows and doors – we’re helping improve your home. Every installation is completed with the care, craftsmanship and attention to detail we’d expect in our own homes, and it’s a standard we’re proud to put our name to.
