Fantastic product and service
Fantastic product and service, couldn’t rate highly enough. Paul provided an impressive pitch and initial demo of the product - even my dad, a UPVC double glazing manufacturer of >30 years, was impressed with the quality of the product and the details on fitting. On price, the initial quote came in 25% below a comparable company and product. Terry did an excellent job on the specification and replicated the horn design on the existing 120yo windows. CJ and team were painstaking in attention to detail on the fitting and finishing. Some windows genuinely look as though they have always been in our SE London Edwardian terrace - but we already feel the impact of the heat retention and noise reduction. Thank you!

A great long term service
SJB completed our last set of windows having worked with us patiently over 6 years to replace all the windows in our Victorian era property in a conservation area. They were very helpful in all aspects including drawings for planning permissions, meeting conservation area requirements for materials and workmanship, plus their communications and installers were always high quality and easy to deal with.

Fantastic Service
We had 5 wooden sash windows replaced SJB did a fabulous job.
Paul, who came to assess our windows and provide the quote was the reason we ended up going with SJB. Compared to other companies [local and national] he was by far the most knowledgeable and thorough.
Jacek did a great job of fitting them and was tidy, friendly and on time every day - Even though it was snowing!
The windows themselves look absolutely perfect. Would highly recommend.

Impressed with the great work making good after the installation!
I was amazed at how quickly the guys completed the installation and very happy with their workmanship. They made a good job around the window opening as I feared that my walls had loose plaster & it would be a major task.

A thoroughly professional firm
A thoroughly professional firm selling a high end product. Not the cheapest on the market but you certainly get what you pay for. The quote system was extremely thorough so you know exactly what you are getting. The front sashes were of a decorative tombstone design and the replacements are an exact replica of the originals despite being double glazed. The work was completed on time and to a very high standard with any mess cleared up. A quality control visit was made before they were signed off as finished.

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.

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.
