At Sapphire Windows & Doors, we’re a family-run business, proudly serving homes across South and West Wales since 1989.
Founded by Russell Matthews, and now led with his son Shaun, Sapphire has built a reputation for quality, trust, and genuine care.
Whether you’re in Carmarthenshire, Pembrokeshire, Neath Port Talbot, Swansea, Cardiff, Bridgend, the Vale of Glamorgan, or South Ceredigion, our family is here to help you enhance your home with confidence.
We’re proud to manufacture all of our uPVC windows and doors in-house at our Ammanford factory.
This allows us to maintain complete control over quality, precision, and sustainability – from design to delivery.
Our experienced surveyors ensure each project is measured accurately before fabrication begins, and every uPVC frame is crafted using state-of-the-art technology and eco-friendly materials.
💬 Our uPVC products are made by us, fitted by us, and built to last.
For aluminium, timber, steel and composite ranges, we proudly collaborate with carefully chosen partners who share our commitment to sustainability, integrity, and craftsmanship.
Our trusted network includes:
Each partner manufactures its products in one dedicated facility, ensuring the same high standards of quality and ethical production that Sapphire stands for.
Every product we install, whether made by us or by our partners, is fitted exclusively by Sapphire’s own in-house installation team.
We never use subcontractors, ensuring complete accountability and consistent quality on every project.
From your first enquiry through installation and aftercare, you’ll work directly with our experienced surveyors and fitters – no call centres, no pushy sales teams, just honest advice from real people.
We supply and install:
All products are energy-efficient, secure, and built for lasting performance – adding comfort, value, and kerb appeal to your home.
For over 35 years, Sapphire Windows & Doors has grown through recommendation and reputation, not sales gimmicks.
We combine decades of experience, true craftsmanship, and a genuine passion for helping people improve their homes.
We’re proud to be a family-run Welsh company that believes in doing things properly – with care, honesty, and attention to detail.
