Each installation complies with FENSA standards and includes a ten-year insurance-backed guarantee for lasting performance.

Bespoke conservatories and orangeries in Edwardian, Victorian, and modern designs.

Durable uPVC fascias, soffits, and guttering systems protect properties from weather damage. Our low-maintenance solutions resist warping and fading, available in multiple colours and profiles to complement existing architecture while improving thermal performance through dry wall construction.

While service was good at point of fitting, follow up service during warranty wasn't the best, but happened with some chasing, after warranty do not expect ANY support even chargeable at they do not want to know! Our roof panel has blown out of place and they offer no support to resolve even with insurance company willing to pay out for it.

This is the third time I have used Custom Glaze now and really couldn't be happier with the service. Everyone we have dealt with has been friendly and professional, and the quality of installation by Billy and Tom was fantastic. A joy to deal with and wouldn't hesitate to recommend.

Used Custom Glaze several times for both window/door replacement and repair work and been totally satisfied. Sales, products supplied, installation and crucially after sales support all excellent.

We ordered a front door with Custom Glaze in August this year, and put down a deposit, and were told it would be around 8 weeks to installation - since then it has been a farce, with a delayed survey, and repeated phone calls to clarify details we'd given previously. The latest, as of Nov 23 - three months after paying a deposit - is that the door we've ordered isn't possible, as the supplier no longer makes the glass we chose. We've been advised to choose new glass, but it still likely won't be done before Christmas, the one thing we wanted when we ordered in the summer. We'd prefer to cancel

Highly recommended in the Milton Keynes area. We have used them for all replacement windows, doors, and cladding over the last 10 years or so. They are reliable, do an excellent job, clear up properly, and don't charge the earth!

Thanks to Adam, Ben and Matt who have just finished changing all our windows and adding three more. The quality of the work is excellent, and despite knocking holes in a couple of walls the mess was kept to a minimum and subsequently cleaned up really well. The windows look great and the team were both professional and friendly. I cannot recommend Custom Glaze highly enough.

We would not hesitate in recommending Custom Glaze, they have been exceptional from start to finish with our conservatory. We were kept up to date every step of the way and were always available on the phone or via email to answer any concerns or questions. All members of the team we have dealt with from the sale rep, our project manager and service department administrator have been fantastic. The workman were always promptly on time, neat and tidy and carried out their work to to a high standard
