Ali & Fi

We are delighted with the windows, and have already been complimented by our neighbours on the upgrade.

Tyler and Paul were very professional and showed good initiative for the inevitable adjustments that needed to be made. They were particularly considerate of our house, it’s character and our pets! Please pass on our thanks and comments as appropriate.


We are delighted with the windows. As you know we were concerned that they would look different and more “clunky” but really you can’t tell the difference except that the new ones are not falling apart!!! The guys who did the fitting were also good. They were working in freezing fog, really cold but they carried on regardless, they were extremely tidy and cleared up after themselves.

I am delighted with the recent installation, it’s good to look out of clear windows. The work was carried out professionally by two excellent gentleman.
I will not hesitate to contact you when I am ready to replace others, also would certainly recommend you to others.

Excellent customer service, range of products and attention to detail. I honestly can’t rate them highly enough. They stepped in and came to the rescue after Salisbury glass cost us 8 months of time and 100k in increased material costs.

These guys have been great to us. Helped us out at short notice after we were badly let down by another supplier. We asked for several minor details that were not standard (e.g. different locking mechanisms), and they were flexible and open to ideas. We ended up also commissioning our front door from them; it is super sturdy and beautiful. Always courteous, professional, and good payment terms.

First class service for my window repair, with tricky access issues and a large, heavy glazed unit to install. Really glad I chose this company.

I was looking for a company that could deliver a bespoke pair of roof lights in the Alitherm system. Techniglaze offered the best price and worked with us to ensure the sizes were exactly right and conducted the sales process very professionally. The product is first class and we are exceptionally pleased with the service and product. I can highly recommend Techniglaze.
