    The Windows group did an excellent job on building our porch. We have already received compliments from our neighbours and we love it. Thank you to Tom for professionally answering many of our questions via emails and phone calls. The team were organised, efficient and always came on time. We were also very happy that payments could be done via a secure link. Definitely recommend and will definitely use them again in the future.

    Very highly recommended company!!! I didn’t know what we were or were not allowed to do with the council requirements of my area and Tom has been extremely patiente with me and provided multiple quotations for different types of windows until I understood what we had to do. His team are excellent professionals and craftsmanships, very kind people, mindful of my newborn baby and dogs. Arrived on time, kept me updated on progress, super clean and the windows look fabulous. An amazing experience with the Windows group, THANK YOU!

Company info

The "Windows Group Ltd" is a relatively new company, but please do not mistake this for lack of experience. I have been in this industry for the last 15 years, working for other companies.

We specialise in all aspects of Double Glazing.

This includes: 

  • Crane lifting and installations
  • UPVC and Aluminium windows and doors
  • Internal Industrial look windows and doors
  • Skylights 
  • Walk-on glass 
  • New build installations and replacements
