Mrs Taylor (4237)


“I had delayed replacing the original windows to my house as I feared losing the fine detail & elegance, but Green Glaze was the answer! They replaced the windows with almost the exact appearance of the original windows – but what an improvement to both the heat and sound insulation!! I am delighted! The company employees and representatives were also polite, helpful and efficient. Thank you.”

Ms Cambell (4267)


“ Great Price, Great Service, Amazing Product – I cannot recommend this company highly enough. To top it off the window fitters were fantastic”.

Will my new windows reduce noise levels from outside?

Yes! Modern double-glazed windows have much thicker glass units than windows of 10 years ago. This cuts down noise transfer, so you hear less noise inside your home, for a more peaceful, relaxing lifestyle!

How long will it take to install my windows?

Exact time depends on the number and style of windows. But as a general rule, a whole house (8-10 windows) should be fitted in 1-2 days

How can I tell if my windows are energy efficient?

Look out for the British Fenestration Ratings Council (BFRC) Window Energy Label. This is similar to the one you may have seen on your fridge or washing machine. A-rated windows are the most efficient and are the best way of improving the energy efficiency of your home.

What are the price on your windows?

Price depends on the specification and size of your chosen window style. To receive an accurate quotation, please call us on 01443 755992 or email
