Key Features
Over time, glazed units can start to lose performance, and that will affect your home’s energy efficiency. Moisture and condensation can build up between the glass panels, meaning the unit has burst and is no longer working at its optimal level. Our replacement glass is the perfect, cost effective solution for all issues, like broken or misted glass. We’re here to help.
Replacement Hinges
In order to keep your windows and doors highly thermally efficient, it is key that your hinges are smooth and in working order! Without this, your double glazing unit can become stiff and unsecure, meaning it won’t be flush with the frame, resulting in unwanted draughts and water ingress.
Replacement Glass
Glass is an essential part of every window and door, and when it cracks or is smashed, it is essential that it be repaired quickly and efficiently. We have a 24 hour emergency repair service for double glazing repairs to get your windows and doors back to working at their optimal performance.

Lesley Skey
Excellent service from start to finish. All communications were clear and accurate. Work was completed to a high standard in just a day. We highly recommend Square Glaze Windows & Doors.
Alan Smith
I highly recommend Square Glaze Windows for their first class customer service. One of my sons accidentally kicked a stone through our front window a week before Christmas. Sher sent out a surveyor around that evening to check the window, size etc.
They ordered the window straight away and were able to replace the window a day before Christmas Eve. Sher kept me updated throughout. Excellent service, I couldn’t ask for more.
Theresa Govier
I highly recommend Square Glaze. They responded very quickly to my initial enquiry and within three weeks the new windows were fitted! The fitters were professional and polite and did an excellent job. All correspondence was clear, and Sher was very helpful. Thank you!
Trevor Coles
We had replacement soffit. fascia and guttering on the front of our home and bay window, plus lead work around the bay window. So pleased; excellent work. Great lads, neat, tidy, precise work. I highly recommend.

Square Glaze recently replaced our French doors, and I only have positive things to say about this company. Starting with the initial request for a quote through to completion of the work, the experience has been first class. Sher’s communication was very professional and friendly.
The two guys that came to install the doors arrived on time, were equally friendly, and did a great job, including cleaning up before they left. I couldn’t fault Square Glaze and would happily recommend them to anyone looking for new windows or doors.
Paul Dearman
Brilliant service from start to finish. I had a broken window and called up on spec to see if Square Glaze could repair it. An engineer was out the next day and did a very professional job.
The room with the broken window was probably cleaner after he left. Very friendly and professional service. I would definitely recommend these guys/gals.
Beverley Brookes
A fantastic service from start to finish. Sher in Customer Service is very knowledgeable and professional. The measuring and installation were prompt and efficient – and the installation team were friendly and communicative.
Very good value too, compared with other companies I found. All in all I would heartily recommend Square Glaze and wouldn’t hesitate to use them again.
Lisa Mackay
Amazing company, we were told by several window companies that our doors could not be fixed, however Square Glaze came out, reviewed and fixed them as good as new and all within a few days!
Affordable prices, very prompt service and very professional and polite workers. Thank you Square Glaze! We would 110% recommend this company.
Chris Rayner
Good communication and quick turnaround. Excellent quality repairs (handles and hinges – also went the extra mile and realigned one of our French doors for us). Highly recommended.
Mrs S Shepherd
