Testimonials

Our customers' feedback is important to us. Read our latest customer testimonials below.

Three first floor windows across the front of our detached house

"The three windows were fitted to replace old, blown units. Mark (the fitter) was efficient, polite and skilled. The quality of the units and the workmanship was excellent and Mark cleaned up any mess he made, both inside and out. I was told by the surveyor that the old units would be recycled which is really good in the present climate. Recycle, Reuse, repurpose. There have been no issues since fitting but there is a comprehensive guarantee included, so we have peace of mind for years to come. Well done Global Windows, which I will also add are a local company!"

- Trustpilot Review, April 2022

Changed house windows and front door

"Efficient and courteous and a job well done"

- Checkatrade Review, October 2021

New windows / doors. Removal of external tiles above downstairs bay window and install cladding.

"Quality service from Global from start to finish. After going through the design process and placing order I was given a start date and that was exactly when the installation started. Product exceeded expectations as did the fitters (Andy and Shaun) who were brilliant. We have an old house that has suffered from some movement over the years so it wasn't a starightforward install but they really paid attention to the detail and did an amazing job. Would recommend to anyone."

Supply and fit new windows and doors

"Competitive price, no pressure at all unlike other companies. Kept fully up to date with courtesy calls and emails. Customer service is excellent. Window fitters Sean and Andy were fabulous. Clean, tidy and friendly but also worked their socks off. Had a little issue with the patio door but sorted this straight away and is now perfect. Would highly recommend. Very satisfied with all aspects from quote to finish."
