"After spending a year searching for the right company to replace our sash windows in a conservation area, we finally found Brett at Sash Window Shop. Brett was professional, and refreshingly transparent - enabling us to feel confident we were in good hands. Brett provided clarity on the style and quality of Sash Window Shop's workmanship. He helped us navigate complex conservation area requirements, explaining all technical aspects clearly. What truly set him apart was his ability to communicate effectively throughout the entire project, with detailed pricing breakdowns to clear timelines..."

"I wanted a solid wood bespoke wooden door with windows and struggled to find what I wanted in North London. I found Sash Windows online and from the moment I contacted them I was impressed. My experience with Brett and Sash window team was outstanding. Brett spent so much time and effort understanding what I was looking for and giving advice, making amendments and offering an honest quote. He is extremely knowledgeable... "

"I would highly recommend Sash Window Shop. We have just replaced all windows of our Victorian terrace with traditional hard wood sashes and the result is excellent. Brett was fantastic throughout the process, and guided us through the necessary planning applications and kept it very stress free. The team who installed the windows were brilliant - friendly, efficient, clean and tidy, and ultimately did a great job fitting the windows. Brett visited during the installation to make sure everything went smoothly. The windows themselves look wonderful and are very high quality - the difference is amazing."

"We have just had Brett and his team back for the second phase of replacing our old Victorian sash windows. Both experiences went really well. The windows are really well made and of high quality. The customer service between Brett and ourselves was excellent. The team that installed the windows were brilliant too. They were fast, tidy, meticulous and friendly too. We will be getting them back for a 3rd phase soon."

"We would highly recommend Sash Window Shop after a great experience from start to finish. Brett was incredibly helpful and presented multiple options for doors and windows to our extension as we were keen to compare costs on differing specifications. Attention to detail and product quality is exceptional and the team of fitters were professional and meticulous. Thank you to the team for ensuring the job was completed to very high standards."

"From beginning to end, the entire process was handled with great attention to detail. Brett guided us through all the available options and even introduced ideas we hadn't considered. The quality and finish of our Accoya windows were outstanding. The installation took place over a few days, and the workers were meticulous and professional, delivering excellent results. I would 100% recommend."

"I've recently had Sash Window Shop replace my two timber sash windows (like for like). The process was a pleasure: fast and competitive quote, great communication, timely reminders about payments, lovely looking windows, swift installation. The company representatives were very self sufficient in communicating with the builders onsite and I received full updates over email. I would highly recommend working with them."

We had a really fantastic experience with Sash Window Shop. Brett and the team could not have been more helpful. Really clear correspondence, always available to chat. Brett came out of his way to show us mock-up windows early in the process which sealed the deal for us. He worked hard to give us a brilliantly competitive quote. Fitting was excellent. Can thoroughly recommend.

We absolutely love our new sash windows which were fitted as part of a wider renovation and extension of our house. The windows are wonderful quality and as good as any original. The fixtures and fittings are also of a superior quality. We happily endorse this company with confidence."

The neighbours have also commented on how good they look!

To top it all off, everyone was wonderful to deal with which is often hard to come by."
