B&G Windows were excellent to deal with. They replied promptly via email and were able to tell me what the problem was from photos I sent them. They arrived bang on time and were polite, helpful and tidy. They explained the issue and were able to fix the window hinge in an hour. Would use them again

I would recommend this firm and would use them again. I booked a survey for a new window and door, but the surveyor, Richard told me that they could be repaired instead. I respect this honesty when other firms try to persuade homeowners to spend more money than they need. The final invoice was for slightly less than the original verbal estimate and all work happened on time.

I used B & G Windows to carry out some repairs to my double glazed windows, which were completed last week. Communication was excellent. A no fee quote was provided, and the work was done well, and carried out at the time agreed. Which meant I could fit my work for that day around the repairs. Both Richard, who did the work, and Kerry, who arranged the timings etc, were friendly and personable. I would definitely use them again. Recommended.

We invited B&G Windows to quote us for a variety of window-related jobs. This included replacing window panes, fixing hinges and replacing handles. They were prompt and friendly in all their communications. They provided us with a very reasonable quote and explained fully how long it would take to source materials and to arrange a date for the work to be done. During the visit the work was completed to a very high standard. They were tidy and caused minimal disturbance to us, perfect as we were working from home. All in all we are very happy with the result. It exceeded our expectations! Our drafty windows are fixed and secure and we can enjoy the views out of our windows. We would definitely recommend B&G Windows.

Lock on UPVC front door broken - safety and security issue - thought it would be a new door but made enquiry by calling B and G as they did repairs as well as new installations and left message. Had call back very quickly - asked to send photos which i did - Richard called back and said he could fix it , gave me the price which i agreed and he picked parts up late afternoon and job was completed same day. Good efficient service and kept me in the picture of what was going to happen and when.

We had new windows installed throughout the house. Lounge, Kitchen, Landing, Toilet, Bathroom and both upstairs bedrooms. B&G were excellent from start to finish. They had a system and it was seamless in execution and all work was finished to a very high standard and it all looks great. The B&G Windows team were personable and engaging and it was a smooth process from initial contact, to getting the quote, to the installation. Truly excellent and highly recommended.

Had all of the glass replaced in our front double glazed windows, excellent job, good price and they definitely knew what they were doing. Communication with the office was excellent and we didn't have to wait too long, from booking the estimate appointment to having the windows fitted was only a few weeks. Would definitely recommend.

From start to completion, B and G windows were an outstanding company. I immediately knew they would make me feel at ease throughout the entire process, and I wasn’t disappointed. Polite, helpful and extremely hard working, I could not be more pleased with their professional approach. I am now the very proud owner of brand new french doors and an external kitchen door, both of which were well-past their sell-by date. Installation was to the highest standard and every, single small detail was catered for. Its always a concern when making this huge kind of purchase but I knew I had made the right decision with them. Do not hesitate when considering this company. I am extremely difficult to please but cannot recommended these guys highly enough.

Richard and Kerry are a great team. Kerry looks after the office side, Richard the installations. They have installed double glazed windows, doors, side panels for me on two occasions in 2023. Kerry goes the extra mile getting the order correct and arranging installation at a convenient time. Fuelled by regular cups of tea, Richard works very hard, is meticulous and tidy, and is quick to resolve any problems that arise. Often he is helped out by the friendly and exerienced Brian. Apart from a high quality new door or window, you would not know they had been here. Competitive pricing, excellent customer service and guaranteed workmanship.

From discussion of replacing two doors on our brick shed, through quoting and installation (and giving our front door a look over), we experienced a friendly and efficient service. Everything was well cleaned up afterwards. We're pleased with the resulting two white doors and the good security that they give.
