This is the third time that we have used Grainger Bower Windows and have recommended their good work to many of our friends. They always finish the installation to a high standard. Steve and Tim both listen to what we need and are both very knowledgeable and always give good advice. Even on an occasion when a window was manufactured in the wrong size, they went above and beyond to sort out a replacement for the next day. My brother in law is an engineer and fussy with tradesman but he also sang their praises. Well done Steve and Tim!

Very happy with the service provided, Steve was very helpful , courteous and professional throughout the enquiry and ordering process - the windows arrived on time as promised and are of great quality - when other companies were unable to supply due to Covid19 GB Windows went out of their way to help. Installation was done by buidlers rather than GB simply ecause they were fully booked and we are in the middle of some buiding work. We are having an extension built soon and have no hesitation in ordering for supply and fit.

We found this company extremely rude and unhelpful when we had issues with our 'whole house' installation. Booked appointments for repairs were missed and owner refused to re-book even though they were the ones who were over an hour late, being extremely rude in the process. Our bi-fold doors also had numerous scratches which they were not prepared to do anything about. We would NOT recommend this company to do anything relating to window/door installation.
