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.

Didn't turn up. No phone call, nothing. Obviously view their time as more important than their customers.
