“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!”
Customer in London
“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.”
Customer in London
“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.”

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. Would definitely use them again!read more

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
