“What our clients say”

“We were going to replace the polycarbonate on our conservatory roof but we were advised by Sharon that short term it would be much better to put the doors and window back in between the kitchen and the conservatory. Great advice and worked out cheaper than our original plan. Would definitely use them again!”

“I’ve just had a front door replaced, patio doors repaired and several windows renewed from a previous less than satisfactory company. Sharon kept me fully updated with pricing, ordering, delivery and fitting. Customer satisfaction is obviously important to this company unlike the previous company I’d employed.”

“I have had a significant number of windows and front door replaced including the encapsulation of the original 1930’s leaded lights by Knowles Stained Glassworks and I could not be happier. Would highly recommend. They are now working on the windows for my planned extension.”

The construction of door is also very important in its performance and durability as thanks to a rigid foam insulation core which helps it retain six times as much heat than a normal timber door. The outside of the door is also very resilient as it has a glass reinforced plastic skin which adds extra strength for security.

Composite Doors Bespoke Stained Glass

We can create bespoke designs or we can alter existing stained glass and encapsulate into a new composite door, also surrounds and side windows.

Excellent customer service, quick turn around for our building project and a lovely finish. I wanted a pretty window... for a family bathroom (instead of just frosted glass). I had a few ideas and the team delivered a double glazed stain glass unit that exceeded expectations. I love it. Thanks for all of the hard work. Images below are before the build finished (and so sorry for the mess). But hope you agree how pretty the window is!read more

We are so pleased with the quality of the encapsulated leaded glass window. Sharon spent a lot of time with us in her... workshop to get the glass colours and design tweaked. The final product was superb and brightens our landing/hall up. The removal of the old window and fitting the new one was very quick by Michael and Tony. We would definitely use Knowles Stained Glassworks again.read more

Sharon was very helpful, responded quickly and gave advice. We had some old stained glass panels which we needed to be... removed from old timber, renovated and then encapsulated in double glazed units. Unfortunately the old glass was not cleaned up very well and therefore we now have to live with the dirty marks on the edges of the coloured glass which is rather disappointing given that this would have not take very long to do at the right timeread more

We were going to replace the polycarbonate on our conservatory roof but we were advised by Sharon that short term it... would be much better to put the doors and window back in between the kitchen and the conservatory. The work was carried out and we couldn't be happier. The quality of the products supplied and the workmanship were faultless. Great advice and worked out cheaper than our original plan.

Needed a window and back door replacing due to renovations on a house. Spoke with Sharon who sent one of her lovely... gentlemen round to measure up and then obtained a quote. We decided to have the backdoor changed to a barn door which looked amazing and fitted in lovely with our renovation project. Highly recommend Sharon and her lovely team all work was carried out to a very high standard and ensured the area was left clean and tidy after. Very happy customer.read more
