Reasonably priced. Excellent service
I got my front door from a supplier I had heard more about but the service was appalling. When I ordered my doors from SGS I was very impressed from start to finish. I had accurate delivery expectations. The gentlemen who fitted my doors were helpful, polite and very patient with my husband who has Alzheimer’s. . I cannot recommend them highly enough.Verified reviewerJob location: TS1010 Double Glazing Installation

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

SGS Windows did a wonderful job from survey to fitting and completion, very clean and tidy which showed in the professional way the work was carried out, would definitely use SGS again when I decide to replace any Windows or doors, my wife was over the moon as she can now sit in the garden without having to unlock gates etc, fantastic job 😀 👍Verified reviewerJob location: SR8RBrian B
