Welsh Window Services
Our aim is to provide high quality replacement double glazed PVCu windows, doors, conservatories, replacement Fascia, Soffits and glass related products. We also specialise in repairing all PVCu, Aluminium and Timber windows, doors and conservatories. In 2002 we opened our glazing shop where we specialise in supplying and fitting of all types of glass to domestic and trade customers.

The Company has built its reputation on high standards of workmanship undertaking contracts from both domestic and commercial clients. We have contracts with many local clients large and small. Larger contracts have included council buildings, educational institutions and also Cardiff Wales International Airport, where our door installations facilitate the movement of over Two million people each year.

It is with the deepest sadness that Welsh Window Systems have to announce that our founder, Cavan Sullivan, passed away following a tough fight with cancer. Please contact Nathan Morgan for any glass, windows and door requirements, new or repairs.

From our larger premises at "Shaftesbury House" Vere Street, Cadoxton, Barry we offer a range of services with all of the relevant health and safety accreditations required for most commercial and domestic widow and door projects.We have contracts with many local clients large and small.
We will soon be entering our twentieth year of business and to celebrate this we would like to offer our loyal customers something extra, that many of our competitors cannot match. This means the original purchaser warranty will now be extended to ten years. This is backed by a Lloyds backed guarantee, free of charge.
We have developed a particular expertise in replacing old and broken wooden box sash windows with PVCu box sash windows that look as close as possible to the originals. This is particularly important in conservation areas or where the character of the original building would be damaged by ordinary windows.
You'll get stylishly slim good looks when you choose windows, doors and conservatories that use the REHAU 70mm system. The REHAU 70mm system is the ideal replacement for traditional British timber casements as the 70mm depth allows for the replacement of 3 timber frames with less trimming up. A number of window types are available in REHAU S706 70mm, including internally and externally glazed Casements, Bay and Bow and French windows.
We are experienced in the design and installation of aluminium secondary glazing. This involves fitting a discreet internal window that keeps the character of your property and exceeds the benefits of double glazing. Whether you're a homeowner or a commercial developer, find out how we can transform your property with secondary double glazing.

Had a good quote from welsh windows in Barry ( workshop in sully) Had new front and back doors upvc fitted both bespoke! Nathan who done the quote and measurements got the front door sprayed to my choice of colour, had glass units replaced in kitchen & bathroom also my old windows adjusted. Great selection of choices EG: glass patterns, shapes and styles of doors, door furniture and colours. Fitting day was given to suit, Amazing team, Andrew, Jake, , & Gaynor in the shop office, very efficient, cleaned up any mess. Excellent all round highly recommend welsh window system.

Great service, quality installation by people who care. We wanted black PVCu windows not white. Cavan and his team went out of their way to source a suitable product for our house which matched the architectural style we were looking for. Excellent fitting - even in a snowstorm, the boys carried on working. They left no mess and the finish is excellent. I would highly recommend Welsh Window Systems.
