S Hyde - South Devon

Now the scaffolding has come down the windows have come into their own, the graphite frames are spectacular, ready contrasting against the stonework. It has been a pleasure working with the team at Green Circle, from the first initial visit to the last unit being fitted the help and advice has been priceless. Quality does come with a price, but it was worth every penny , a company is only as good as the staff that work there. 10/10 Green Circle. Thank you.

Clive and Maggie, Blackawton

Good to work with the design team, and a very helpful site install manager

Mr Williams, Totnes

We are so happy with our new Green Circle windows and patio doors. These were retro fitted recently to replace some UPVC units by another supplier, which were not that old but had caused us too many problems. Since getting these replaced by Green Circle windows and patio doors, we can really see and feel the quality. Condensation is no longer an issue, and they allow in much more light. They keep us warm and cosy. We would like to give Green Circle A++++++ for their service, the quality, look and smooth and easy operation of the patio doors and windows, for their excellent function and fit! We highly recommend you using this company.

After 8 years of Green Circle Bi-fold usage…I thought I ought to maintain them a bit !!
I cleaned the grooves they run in, and sprayed silicon grease into the hinges, wheels and runners. There is no rust, no sign of wear, no loosening or wobble. They work as well as the day they were installed. Its a good product Kim. Thanks very much.
