Excellent customer service
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. I would thoroughly recommend.

Sash window replacement success
Clear details of costings, materials and installation requirements were provided and the installation went ahead with a minimum of fuss; floor coverings and final dust removal were well executed and a follow up visit to free up the sash window occurred without question. I would certainly use this company again.

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.

Dear Scott,

Your project was indeed a complex one, and we’re proud that Constantin’s expertise and can-do approach helped ensure everything was completed to a high standard.
We’re equally pleased that the new windows have met your expectations. Your feedback means a great deal to us, and we appreciate the confidence you placed in our team.

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.

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!

Once again, thank you so much for taking the time.
All the best,

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.
