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. The windows are excellent! I would thoroughly recommend.

Excellent service

The windows are absolutely gorgeous! They have changed the entirety of my flat - and the service received was spectacular!

10 stars!

Website, communication, site visit and quotation process was handled swiftly and well. Price quoted competitive and not as high as other shortlisted supplier. Fabricated windows produced to a high standard.  Work was scheduled earlier than expected. Professional and skilled installation.
