Sashwise now replaced 12 sash windows. Very happy with the quality of the workmanship and the fitters are efficient, tidy and easy to have around. Highly recommend.
Installation of double glazed sash windows
Fantastic work on site from Dan and Zach from initial quote to finished product. Very clean and professional. The admin team was very good at getting in touch for scheduling and answering questions I had. I would definitely use SashWise again.
Replacement casement windows
Sashwise replaced 3 sets of openers in our Victorian terrace house in Chiswick. Despite the original casement frame age 130 years (and the resultant lack of squareness given its age) Sashwise did a brilliant job and manufactured and fitted 6 beautiful new hardwood double glazed openers that look great, fit perfectly, and have integrated draught seals that really work well. The company was easy to work with and we wouldn't hesitate to recommend them to take on a task of this complexity again - given every other company we asked to quote insisted on replacing the casement frame as well.
Replacement of sash windows with double glazing and refurb of sash boxes and surrounds throughout.

10 / 10 - Fitting double glazed windows (wood frames)
From our first meeting and conversation with Daniel I was hugely impressed by his knowledge, honesty and professionalism. The quote came back quickly with all questions answered and the work was delivered as per the timescales agreed. Daniel left the house clean and accessible at the end of each day and the final results are absolutely fantastic. I highly recommend this company.
Installation of double glazed sash windows and refurbishment of existing boxes.
We had seven old single pane sash windows replaced with new double glazed sashes and the existing boxes refurbished, together with a small casement window. We are delighted with the results, with the improved soundproofing a pleasant surprise on top of the excellent quality of the windows and thermal and draught insulation. The communication from the team was clear and the work was completed much quicker than expected. It was particularly good to be able to refurbish the boxes while installing new sashes. Would definitely recommend Dan and his team.
Replacement sash windows
I would highly recommend Sashwise. Dan was great when he came to measure up and explained everything clearly. Tim completed the work to a very high standard. My flat was left very tidy afterwards. My new windows are fabulous. They look just like the original sash windows, but it is now so much quieter and I have no drafts.
Replacing old timber sash windows with new timber double glazed windows.
Sashwise replaced the majority of the timber sash windows in my house. I hired Sashwise ten years ago to replace some windows in my previous house. They are excellent, I couldn’t recommend them more highly. They work quickly and cleanly with minimal fuss and I received my windows earlier then I expected. The results are remarkable, the rooms and definitely far warmer and the windows are top quality and look beautiful. Even my neighbour complimented them!
