I had draught proofing and overhaul of my timber sash windows. The quality of service was exceptional. They came on time, covered up the whole area and efficiently did the work. It was tidy, quick and high quality work. Prior to this the customer service was exceptional as I explored different insulation options.

I had all 7 original sash windows replaced - Greg and the team were fast, efficient and helpful. I had been dreading the disruption as I work largely at home, but they were finished in 4 and a half days and the results not only look great the house is so much brighter and warmer!

Great! We had new sash windows installed as well as existing ones refurbished and The London Sash Window Company were brilliant throughout the process. From the intial quote and surveys to the final installation, they were amazing. The quality of the windows is fantastic, the installation itself was quick and professional, and the customer services were great. Would recommend.

Professional, helpful, and efficient replacement of sash windows in a conservation area - so facing a fair amount of red tape and requirements! The windows are great quality - I can already feel and hear the difference of the double glazing in terms of cold and outdoor sound.

The work was carried out professionally with a minimum of fuss. From the first estimate to completion, the job was seamlessly delivered. This is the second time we have used the London Sash Window company and we are delighted with the quality and results of their work.

This company have now replaced the original 1861 sashes at both the front and rear of my flat - I would recommend them very highly for the quality of the manufacture and installatioin and the clarity of communication.
