Window replacement
The company had very good reviews on Checkatrade so I contacted them to replace an old single-glazed frame and broken outer sill. Excellent communication from Vic and Kamran at the office. The team who came to do the work were friendly, polite and very efficient. Despite some pretty hideous weather, they completed the job, to a very high standard, in a little over an hour. They cleaned up so well that you'd hardly know they'd been. I can definitely recommend this company.Verified reviewerJob location: SE610 Double Glazing Installation

New Bathroom and Toilet windows
We contacted SDG Windows about replacing our tired old bathroom and toilet windows, from our initial first meeting the SDG team were professional and courteous. This was a bespoke order with a lead time of about 4 to 5 weeks. The date was set for the installation and all went exactly as planned, the team arrived on time and swiftly began the work. They really did a fantastic job and the new windows look great. We would definitely recommend SDG Windows.Verified reviewerJob location: SE2610 Double Glazing Installation
