Quite simply the best!
It is many years since I have worked with such a professional and capable business. The preproduction process was meticulous with me in control of all sign offs. The windows and doors from the factory fitted and operated perfectly first time, fantastic quality. The team of installers Bobby, Mitch and Jack were polite, hard working, highly skilled and punctual, protecting our rooms and tidying after each day. Overall the service from estimation to completion was faultless. Quite simply the best!

Communication was always quick and…
Communication was always quick and clear from the outset - including the presentation of the quote. The fitting of windows and a door was smooth and the staff friendly and professional and great at clearing up after. And the new windows and door look great and we already notice the difference.

The service was excellent, all staff were professional and courteous from start to finish. SJB is family run and they care about the customer as well as clearly being technically strong, and very knowledgeable in what needs to be done and how to get the best results for your windows. I would thoroughly recommend.

Clear details of costings, materials and installation requirements were provided and the installation went ahead with a minimum of fuss; floor coverings and final dust removal were well executed and a follow up visit to free up the sash window occurred without question. I would certainly use this company again.
