10 Double Glazing Installation
Posted 1 day ago
Honest, good prices, and good service
I recently had 3 windows installed by SGS windows. I needed them doing badly as two had wooden frames which were rotting. Alan came to look at the job, was honest and open throughout the meeting. Told me triple glazing wouldn't make much more of a significant change due to me being in a very secluded and quiety location, but compared to the existing old windows double glazing would be much better. they offered me an unbeatable price, they installed them promptly and i must say WOW! What a job! They look so good and i'm over the moon, these are so much better than my old windows.Verified reviewerJob location: DL110 UPVC Windows Installation

Superb company fantastic quality
"I honestly couldnāt fault SGS Windows from start to finish. They were incredibly professional and did a fantastic job! The fitters were great, always kept the workspace tidy, and had a brilliant eye for detail. A special mention to the main fitter, who was fantastic throughout the entire installation. My house looks like a brand-new home now, and the price was brilliant for the quality of the windows I received. Highly recommended!" 5 starts doesnāt seen enoughVerified reviewerJob location: TS10
