10 Great Company!
Posted 1 week ago
I again used Diamond Windows to fit all new 'triple' glazed replacement windows at the rear of my house. I am so pleased with the price, quality of the product, and the great workmanship. We have previously had Diamond Windows take out and replace all our front windows with 'triple' glazed replacements, and also our front door with a composite unit and I can thoroughly recommend this company to anyone looking to install replacement Windows, Doors, Conservatory Roofs etc... Great value, great product, great workmanship, and they always leave it clean!!Verified reviewerJob location: GL410 Excellent work good price

Most recently Dave and Ryan have installed a set of French doors, kitchen and utility room windows for us as part of our kitchen renovation. Prior to this they had changed every other window and door on our property. We couldn’t be happier with the transformation it’s made. Dave and Ryan’s work is to a very high standard and I’d definitely recommend them to anyone. They are also very nice people who are customer friendly.Verified reviewerJob location: GL110 They do a great job!

Diamond Windows have previously replaced all our windows and doors to a very high standard. We are very happy with our recent roof upgrade. The room will now be suitable for all year round use. Their quality of work is excellent, very clean and tidy, and finished within the estimated time frame. Would highly recommend.Verified reviewerJob location: GL210 Fit new windows on kitchen bathroom and bedroom
