The team at GBS are highly skilled and professional. They have great pride in their craftmanship that shows in the quality of the products they design and manufacture and the care taken by the installation team to ensure that fitting was flawless. Customer service was excellent, from the initial planning stage right the way through to post-installation.

GBS have replaced original leaded windows in our 1930's house in Hazel Grove, Stockport in November 2020. The whole service was outstanding, from the initial visit to the final installation. The quality of workmanship in the manufacture and installation was exceptional. The leaded lights were renovated and rebuilt into new double glazed units and this has retained the original look very well. The team at GBS work together to provide a top class job and we can unreservedly recommend them. Jackie & Steve Tiffany

A big thank you to GBS for their professional and excellent service. I was delighted with their craftsmanship and dedication to the job. My finished windows/doors look fabulous. The fitting team worked brilliantly and they always left everything spotless.

We are absolutely delighted with our high quality, beautifully crafted sash windows from GBS Joinery. They’ve made a huge difference to warmth and sound levels in our house, and suit the style of house perfectly. From first contact, the team were great to deal with and kept us up to date on progress. Ryan and Brian installed the windows with skill, attention to detail and no fuss. The whole experience with GBS Joinery has been excellent. We have no hesitation in recommending them to anyone looking for a high quality product with outstanding customer service.

From initial contact to finished installation everything went smoothly. We had all our existing uPVC windows, porch, front & back doors replaced. The installation took about three weeks & can't be faulted.The appearance of the cottage has been transformed.The care taken & genuine pride in their work by fitters (Andy & Ryan) was obvious & is reflected in the finish.I would recommend GBS Joinery without hesitation, sadly this is becoming very rare these days.
