Brilliant from start to finish
Brilliant from start to finish. The initial appointment was very helpful, the advisor took time to explain pros and cons of different approaches (full replacement vs replacement sash etc.) and provided multiple quotes to help consider.
Installation began and finished on time, the 3 members of the installation team were all brilliant, especially Rob who took time to explain what they had done at the end of each day, plans for the next day etc. A couple of minor issues such as a faulty door lock were identified by the team, explained and resolved quickly.
Very pleased with our new windows and door. Thank you.

Great experience and would recommend
Excellent quality, price and installation. The windows are perfect, just what we wanted, they introduce more light into the room and look great. What could have made this 5/5 are improved communications - I was away for the planned installation dates and expected the installation to begin on a Monday as agreed, I received an email on the Tuesday to say works would begin on Thursday - this impacted my plans to the property quite significantly and I felt this should have been communicated on the previous Friday by phone call (received an email on Tuesday). After installation there were a couple of things I asked if they could be remedied, again the works were done very well but I had to follow up after a week to get the works scheduled in again. Definitely recommend the company - and Clebber & Marcel (installers) are great guys and hardworkers

Good installation
Good installation, good communication throughout.
We've just had two sash windows replaced, but it looks good. The area was left tidy and only required minor touch-ups (to be expected when two windows are ripped out). We were surprised how little work it required.
The windows are good quality from what we can see, and look good too!

Product and overall installation is…
Product and overall installation is high standard, pre-install service great and helpful. Some minor issues with install (left the site messy, minor issues with finish, minor damage to property) which proved challenging to resolve and completely unwilling to offer any discount despite not all damage being possible to repair, not to mention wasted time and effort.
Need to be more customer focused when things don’t go plan.
Edit following reply: to reiterate the product is great, the tone of this reply is the issue when things don’t go to plan.
Agree to disagree, it's just my view.
No issue with snags, they are fixed.
Site left a mess and damage to child cot which was denied by fitter - not OK really.
£50 discount off a £6k job when also adding £60 for parking when I paid for permits, also not really OK. I expected a couple of hundred quid discount & my view would be very different.
For anyone reading, windows are great, would use again.

Dear Will,
Thank you for your review. Sorry to hear that you feel it was challenging to resolve the issues.
However, I think what you have written is a bit inaccurate. You emailed us on the 10th of June highlighting a snagging list. We replied the same day asking for some pictures, so we could assess what needed to be done. You came back to us on the 11th of June and we visited your property on the 12th. We rectified the issues that you had highlighted within 2 days of you bringing them to our attention. I even have an email from you that reads “To confirm all sorted – thanks again for coming over and rectifying these issues quickly.”
Furthermore, we not only offered you a discount, but applied a discount to your invoice. Clearly you aren’t happy with the level of the discount and this is where your “review” has come from.
There is no tone to this reply. I have simply stated the sequence of the events, which contradict parts of your review. It is quite clear you simply weren't happy with the level of discount we granted.
We take all feedback seriously and are constantly reviewing how we can do things better.
Brilliant trust relationship from start…
Brilliant trust relationship from start to finish. Was walked through the requirements as we have a preservation order to deal with. Fitters were onsite at 7:30 each day and did a full shift to get the job done in 3 days and 7 windows.
Really impressed with the service - well done guys!

Great service from start to finish - it wasn't the easiest of jobs but Terry and his team were creative in the way they approached it and once on site were a pleasure to have around! Would highly recommend.

Highly recommend SJB Windows, delighted
I had had a horrendous experience with one of the other London based sash window companies. I don't feel comfortable sharing which company here, but I'm sure SJB will happily tell you if you ask them as they put up with me wittering on about how stressful it was on several occasions! It was awful and I had to file a Section 75 claim to get my money back on that previous contract from my credit card company. It was a distressing and time consuming experience. So I can honestly say that having my windows finally made and installed by SJB Windows was a fantastic and seamless experience; I put the order in as soon as I got refunded the (many thousands of pounds) payment I had made the other company, who left me with windows that didn't fit, butchered walls, and without half the windows I had paid for. SJB measured correctly, they had a decent lead time, they communicated articulately and clearly, the windows are high quality, the installers were lovely, and their finish to a pre-decorative standard of the walls around the new boxes (nasty messy job taking the old ones out) was of a high standard. I am delighted with my new windows (new boxes and sashes) and they look fabulous. Already some neighbours have said how smart they look. Thank you to everyone at the company, you gave a terrible situation a happy ending and I so relieved. I would very happily recommend you.
