A very pleasing result.
A long time between ordering and fitting (partly to do with Covid), and a couple of small logistical issues on site, but in the end a very nice product expertly fitted by Steven.
The final product, as promised, cleverly retains most of the details of the original Edwardian woodwork and looks great. Very pleasing. And warmer too!

A Front Door of Exceptional Quality
Terry Macdonald's assistance in drawing up the complex Leaded Stained Glass Panels made the design and construction of our front door uniquely special and a thing of beauty. The installation went smoothly and the After Sales Service was excellent.
Thank You SJB Sash Windows

I was away from home on business at the time but they were fantastic with their communication and coordination .
Very happy with the result of the installation and the final product. I’ve got more windows yet to upgrade so will definitely be using them again.

Truly excellent from start to finish
Truly excellent from start to finish. From the initial sales quote, to the measuring up and surveying, to the actual installation, everything was done perfectly and efficiently. We got all new double glazed timber sash windows throughout our property and they look amazing. The lead time on the windows can be a while but same as any other place. The service and job done by SJB really stands above the rest. I would highly recommend and would use SJB again for any future windows.

Wonderful doubled glazed sash windows that match our Edwardian terrace house
The windows themselves fit perfectly with our Edwardian South London terraced house, yet they have very advanced double glazing technology to give the best possible energy performance. The guys that fitted our windows were also fantastic making the windows fit in so no big redecorating job. Finally , in the bathroom they were able to use murano patterned glass as part of double glazing unit. It looks beautiful and fits the rest of the house.

Great - quick and clean service. Removed windows and installed new ones professionally without too much damage to walls, surprisingly. Made surrounding walls good - very neat job.

Amazing service from start to finish
Amazing service from start to finish. I had two windows put in before so I knew that the quality was going to be good but have to say that the window fitter was exceptional - he went above and beyond and now all my windows have been replaced and they look phenomenal and help keep noise and the cold out. It is a worthwhile investment.

Five Sash Windows Fitted
I've had five double glazed sash windows with acoustic resistance fitted in a property built in 1875 and they look as they should. The quality and fit of the finished windows is excellent. I was advised well at the beginning of the process and communication remained good throughout.

Excellent company that makes beautiful sash windows
SJB installed two timber sash windows in my property. The result speaks of a truly high quality work: the windows are beautiful to look at and they feel robust.
The order-, and the installation-process were smooth; the company's communication was great; and the installer was extremely kind and tidy.
Thank you for the excellent work.

Professionalism at its best
SJB Sash Windows replaced an old bay window on our flat and the result was excellent. The window looks stylish and the finish is of a very high standard. The installer was punctual, hardworking, tidy and extremely professional. Congratulations on a good result.

SBJ was very professional from start to finish. They explained thoroughly the options and finishes to us and provided diagrams of what the windows would look like. After waiting many years to have our sash windows replaced, we are very pleased with the end result. High quality workmanship and finish.

Absolutely outstanding and professional
SJB Sash Windows installed two new double-glazed sash windows and boxes which are absolutely beautiful. They did an amazing job, with really great communication, and such a fantastic and skillful installation team. Wished we knew them a lot before. Highly recommended!

Really excellent work and very professional company !
SJB replaced sash windows in my flat and fitted a new kitchen door. From start to finish, survey to fitting, the company were super efficient, professional, courteous and friendly. I would highly recommend them; the work was carried out to a very high standard and I am absolutely delighted with the results. Jake in the office and the two fitters, George & Blago are worthy of special mention but to be honest, everyone I dealt with was professional and thoughtful.
