  French Doors Installation

  Posted 4 days ago

  New French Windows.

  We had old rotting french windows replaced with new double-glazed doors. Very knowledgable sales director visited and went through the options. Immediate competative quote which we accepted. They then took accurate measurements to construct the doors. Very happy with the installation and the final result. Workmen put down protective sheets and covered soft furnishings so no mess. They look stunning.

  Wooden Sash Windows Installation

  Personal, professional, efficient, clean & tidy service

  Personal, professional and efficient service. Really clean and tidy as well. They’ve now done 6 windows for me in 3 different visits. They have done a great job each time. This most recent time (October 2026), I had the best, wooden sash windows they have and they're absolutely beautiful, high quality and super-secure. I just have two windows left in the house to replace now and looking forward to Sash Windows London coming back to do them for me. I don't hesitate to recommend them.

  UPVC Windows Installation

  The best experience

  Everything from start to finish was amazing with Sash Windows London. Atul was incredibly attentive and thoughtful when he first visited the property, taking care and consideration into our ideas. The installation was seamless and pricing very competitive. I couldn't recommend them more and we are beyond happy with the final result.

  Timber Sash And UPVC sash windows

  I had 7 timber sash windows and 2 UPVC windows manufactured and installed by SWL. Overall I had a great experience. The sales team were very professional, providing solutions for my requirements. The communication during manufacturing and organising installation was excellent. The installation teams were fantastic. Efficient, hard working, clean and tidy, very polite and respectful and the quality of their work was outstanding. Above all the quality of the manufactured product was first class and faultless. This is a great company with a first class product and would highly recommend.

  Bay Windows Installation

  Thank you Sash Windows!

  We are very pleased with our new windows from Sash Windows! We had a front and side bay completed and the quality of the UPVC is very good, and looks very professional. Very were happy as well with the communication before and after the service, as the Sash team helped advise us on which quality of windows to pick which was perfectly suited to our needs. Big thanks to the Sash team!
