Josh and Dean were very easy to deal with. They did a first class job replacing glass, including removing an old sash window to re glaze it. Very good communication, they let us know when they were coming, and I would not hesitate to use them again.
First class service

Highly recommended
Josh and Dean from Unique Glazing are the only professionals we would ever want fitting new doors and windows at our property. Their teamwork and attention to detail is second to none and we would highly recommend them to our family and friends. Great work lads and thank you 😀

Unique glazing were superb from 1st consultation to the finished product. We had moved and the conservatory had an old polycarbonate roof which meant the space was unusable as far too hot. Now we have a fibre glass roof which has been fully insulated, plastered with additional lighting. We now have a beautiful room we can use all year round. Can’t thank Josh and Dean enough and fully recommend to anyone looking to have work done!

Unique Glazing were recommended to us and we were not disappointed. From measuring up to installation they were first glass. No surprises on cost or quality. Will be using them again.

Unique glazing replaced a backdoor and frame for me today. It took 95 minutes. It looks great and works well.
The team got down to working immediately on arrival and left everything clean and tidy (you would not known they had been!). Very good craftsmen. I have no hesitation in recommending Unique.
