At Sapphire Windows & Doors, we’re a family-run business proudly serving homeowners across South and West Wales since 1989.
Founded by Russell Matthews and now led alongside his son Shaun Matthews, Sapphire has built a reputation for quality, honesty and genuine customer care. For more than 35 years, we’ve helped thousands of homeowners improve their properties with beautifully crafted, energy-efficient windows and doors that are built to last.
Today, we’re proud to welcome customers to our two showrooms in Ammanford, Carmarthenshire, and Milford Haven, Pembrokeshire, making it even easier for homeowners across Wales to experience our products first-hand.
Whether you’re replacing a single window, installing a new front door or transforming your entire home, you’ll receive honest advice, quality products and expert installation from people who genuinely care.
Choosing new windows and doors is a significant investment, and we believe you should feel confident every step of the way.
Homeowners choose Sapphire because we offer:
Our reputation has been built on trust, quality workmanship and recommendations from happy customers across South and West Wales.
Since opening our doors in 1989, Sapphire Windows & Doors has remained committed to delivering exceptional craftsmanship and outstanding customer service.
As a proud Welsh family business, we’ve grown through recommendations rather than high-pressure sales techniques. Every member of our team shares the same values – honesty, integrity, attention to detail and genuine care for our customers.
From your first enquiry through to installation and aftercare, you’ll deal with experienced local professionals who take pride in helping you make the right choice for your home.
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.
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:
Every manufacturer has been carefully selected because they share our commitment to craftsmanship, innovation and sustainability. Combined with Sapphire’s expert surveying, in-house installation teams and outstanding aftercare, we’re able to offer homeowners some of the finest windows and doors available anywhere in Wales.
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.
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.
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.
