    new PVC windows installed

    Posted 26 November

    Alan at SGS Windows has efficiently and very professionally installed 3 french doors and an unusual opening round window in my flat. He was meticulous in measuring and ensuing that I got the style and type of doors I was after. He offered good advice and he keenly priced the job. He took just two days to install the windows, working hard and tidying up as he went along. His colleagues were polite and professional and hard working. I would recommend SGS Windows.

    Pleased with the quality of work carried out

    Posted 11 November

    My elderly mum recently had a front door fitted and is over the moon with the quality of work carried out. The team were friendly, and supportive of her needs. She said they tidied up after themselves, explained the process clearly and carried the work out to a high standard. The front door itself looks lovely and the price paid was very reasonable. We would definitely recommend.
