The windows are absolutely gorgeous
The windows are absolutely gorgeous. I am so so happy with them, and the workers from SJB were also so lovely, kind, and communicative.

SJB replacement sash windows
Very impressed with this company, from start to finish the experience was easy , professional & excellent quality. My project & installation team communicated regularly, the guys on site managing the sash replacements were friendly, considerate & delivered an impeccable finish. Not a cheap product, but you get what you pay for & I am over the moon with my new windows. Would thoroughly recommend!

Very Professional
From initial visit, quotation and completion this was a very smooth job. It was unquestionably a difficult 4th floor window replacement and our installer, Constantine, was a multi-skilled professional who just got on with it, where others might have balked. Lovely windows as promised.

Beautiful quality windows and door
Beautiful quality windows and door. Ordering process and pre-installation contact efficient and responsive. Installer very nice, polite and tidied up well. Only misses 5 stars because of untidy paint retouching (recommend asking SJB not to retouch edges of windows and just do these yourself with masking tape later).

Installing wooden sash windows
Website, communications, site visit and getting a quotation was handled well. Competitive price quoted. Lower than competitor we'd shortlisted. Able to schedule a slot for installation more swiftly than expected. Work was carried out professionally and a high standard.

Great windows and installation
The window installers were efficient, polite and took loads of care. They clearly loved installing the windows and were proud of how good it looks. As are we!

Very professional service
I had a great experience with SJB replacing wooden 3-bay sash windows. The whole process was efficient and professional from sales through to survey and installation. I found the team very helpful and pleasant to deal with (answering all my many questions with patience!). The installation went smoothly with very little mess and the windows look great.

Excellent experience
We had PVC replacements of both sash and casement windows fitted. The fitters (Cydrell and Dominic) were extremely professional and worked rapidly finishing the whole house within a week. The disruption during fitting and retouch painting needed afterwards was much less than expected. The new windows look great!

Thanks to CJ, Leroy and Blogi!
The three guys (CJ, Leroy and Blogi) were all really conscientious and hard-working professionals. I had 10 windows replaced and they clearly realised that it was a big and stressful deal for me - so did their level best to proactively reassure me and to explain what they were doing. No detail was too small for them and they never made me feel that I was pestering them (even when I relayed on concerns from the block management). I was very grateful to them for working so hard to clean up the dusty mess afterwards.All in all, this job went just about as smoothly as possible.

First rate service, great quality, good price
First rate service from this well-established family firm – from initial contact through to the final invoice. Very well-made windows, professionally installed. Competitively priced.

Good job overall
Overall the experience with SJB Windows was good with prompt email communications, helpful staff and a clean and efficient window installation. The only fly in the ointment was an unforeseen and fairly last minute change in the installation date which, fortunately, was ok.
