Our Testimonials

Just a few words to say thank you Celsius Windows for the lovely door I had fitted, the workmen were very pleasant and left no mess. I am happy with the service I received and I would recommend.

C Aitchison - Gowkshill, Edinburgh

Contacted Celsius agreed a price with John, three weeks later the windows were installed with the minimum of fuss, no mess they even hoovered up at the back of them, I had a faulty mechanism on an existing door and that was replaced free of charge. Quality work indeed and would not hesitate to recommend this company to anyone wanting to install double glazing.

Les Donkin - Dalkeith, Edinburgh

Just a note to say how pleased I am with the new windows and to praise the workmen who came. They were extremely polite, helpful and tidy – you would never have known they had been in the house! I will certainly be recommending you to family, friends and neighbors.
