Business overview

South Wales Premier Double Glazing & Guardian Roof Installers

Window Doctor have over 40 years of experience in the double glazing trade. We specialise in quality A Rated products and have an enviable reputation for installing windows, doors and conservatories right across South Wales. We are also proud to be one of only a few companies that install Guardian roofs on conservatories, giving you that fantastic tiled look while also keeping your conservatory cool in the summer and warm in the winter

In that time, we have built up a vast knowledge of the products on offer and what can go wrong with them. We are also one of the only repair companies in the Swansea area equipped to ensure professional diagnosis whatever the problem. More often than not, I can even diagnose faults over the phone. Call us free now to see if we can help!
