    GM Windows came out to my home to provide a quote, on time, and gave me some good advice when I asked for information about security upgrades available for French doors! Installation went great, very progressional service by the team, and left the place spotless.

  • New back door and bathroom window

    10Verified Review

    I urgently needed a new back door and bathroom window fitting and GM windows & doors fitted me in last minute. The quality of product was just what I was after and I was able to customise the glass and add additional security measures to it. There was a slight issue with the finish of the sealant but the team promptly came back out and rectified this to a quality standard with no questions asked. I have already recommended GM windows & doors to friends and can’t commend them enough for how fantastic they have been!

    Exceptional service from start to finish! From the initial consultation to the final installation, the entire process was smooth and hassle-free. The craftsmanship and attention to detail were evident in every aspect of the job. Not only did they perfectly fit the bathroom window to my specifications, but they also went above and beyond to ensure it complemented the aesthetic of the space. Professionalism, efficiency, and quality workmanship – I couldn't be more impressed. Highly recommend their services to anyone in need of window installation!
