Highlights
"We’ve had J&B Windows to fit 3 new windows at our house and we are very happy with the work. James was a true professional from the first call and all the way through the job and he made sure everything was perfect and looked after our property while working there. Great communication throughout and very easy to talk to and get on with. Great attitude towards the work and customer. We’ll definitely be having them back for future work and wouldn’t hesitate to recommend. Thank you James"
"The company was recommended to me and the service provided was excellent, from the estimate through to the completion of the job. I would have no hesitation in recommending the company."
"I recently had J and B windows to replace the windows and change the roof on my conservatory, and I couldn’t be happier with the outcome. From start to finish, they provided an outstanding service. They were both friendly and approachable, always on time, and communicated clearly about each stage of the project. I was especially impressed with how clean and tidy they kept everything—they left the space spotless every day. The quality of their work speaks for itself, and the finished product has transformed my conservatory. I highly recommend them to anyone looking for skilled, professional window fitters. Thank you for a fantastic job!"

I have had james quite a few years ago to fit some windows so had no hesitation getting him back to put a new roof on my conservatory. he has done an excellent job removing my glass roof and installing a warm roof. he even plastered the inside and fitted down lights. I would recommend these 2 lads to anyone. excellent job maralyn
