Couldn't be happier
We've just replaced a number of windows with SJB and we couldn't be happier. From the original visit to provide a quote, all the way through to installation we've received excellent communication and service throughout. Our fitters (Michael Marcello) were professional, efficient and did an amazing job. And the windows themselves are brilliant- good quality, solid build. Thanks SJB!

Outstanding windows and fitting experience
An outstanding experience from start to finish. Measuring up and specification process was great. And any queries were handled politely and promptly by the office. And the fitting couldn’t have been better. Jon and Joby arrived promptly every day, made sure everything was protected and then cleared up afterwards at the end of the day. They were friendly and courteous, making sure we knew the status and plans.
We had 9 windows and 2 doors, so not a small job. The windows and doors themselves are of very high quality and the fitting is faultless including plastering where required so all we have to do is some decorating to make it all good.
Couldn’t recommend enough!

Excellent quality and service
We got three of our windows in a period property replaced with double glazed windows from SJB Sash Windows after two of our neighbours had recommended them. We have not been disappointed: the windows are beautifully finished, and were put in without drama by very courteous and extremely hardworking installers. The experience was so positive we are going to replace other windows in our house with SJB sash windows too.

Totally faultless experience. From measuring up, keeping me in the loop on timings and the installation team were a dream. Would recommend SJB in a heartbeat.

Outstanding and impeccable service
This company has the highest standards in all areas. Fantastic advice during the consultation (Paul was the perfect, non-pushy and knowledgeable consultant), a professional discussion throughout the survey visit (Terry took me through everything and reassured about the fitting), and faultless work during the fitting (Michael and Marcello, a dream team!). I needed to send documents to the management of my building and SJB were instantly able to supply these and highlight the quality of their work and their impeccable customer service. Michael and Marcello, who fitted the windows, were exceptional. Lovely, personable guys with a great sense of humour, but extremely diligent and incredibly hard working. The quality of their workmanship from the fitting, carpentry and masonry was outstanding. Post window fitting, I had a few questions and these were all answered swiftly and professionally by Jake, and resolved efficiently by Michael and Marcello. I met many window companies before choosing SJB and it came down to the fact that they oozed quality, had fantastic customer service and clearly understood my specific requirements. I am very fussy and have a forensic eye and wouldn’t hesitate in recommending SJB! Look no further!

Great company
We are very happy with the company, from the initial sale discussion, to the survey and installation of double sash windows. The team in charge of installing also plastered around the box c. 10c and painted a line on the ledgers outside - so now we only have to sand and paint inside and finish up painting outside for it to look complete.

Great experience from A to Z with SJB
Great experience with SJB from beginning to the end.
The team was very clear and professional at every stage: initial measurements, quote, on-site measurements, order, manufacturing and installation.
The team was always available on emails and on the phone to answer our questions and update us on the timeline.
Installation was fast (4 instead of 5 days for 7 windows) and clean. They were arriving on time in the morning and providing us a daily update.

Very helpful information in deciding most appropriate product. SJB team, Jake and Glen, honoured all plans and deadlines and were responsive and helpful throughout the whole process. Our tenants were involved and included in all arrangements by SJB for a good finished installation. We are very pleased with our service.

PERFECTION The Bestest of the Best!!! 100stars out of 10
I don’t know where to start as every aspect of our 4 window install was just FLAWLESS.
From the booking, the initial visit as well as the survey up to the fantastic endresult I cannot praise this company more. The best experience I had concerning building works ever. Thank you to everyone involved in the build up to the install! PERFECTION
But a massive thank you to Michael & Marcel. Their skills, work ethic is one in a million. A smiling, caring, hardworking, skilled, talented, polite, punctual, tidy Duo I was actually looking forward seeing every morning! Their perfection in the craft is obvious as the result is stunning but also they are so fantastic to have around.
What lovely and courteous people Michael and Marcel are. They work so hard, always so kind and compared to what I expected concerning such big building work it was handled so so well, constant tidying up and brilliant work from these two superstars made it a amazing experience with absolutely beautiful windows.
Thank you Michael and Marcel for a installation which was absolutely outstanding. The results are outstanding and the experience during the installation as well.
Highly recommended
-Booking 10/10
-Visit 10/10
-Survey 10/10
-Communication 10/10
-Windows 10/10
-Installation 100/10
Michael & Marcel you are amazing!
Mille Grazie
