10 What a relief - a big job made easy!
Posted 1 day ago
Job location: SW18I 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!- NNeil K
10 Great company

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.Verified reviewerJob location: SE13 8 Good quality products and professional fitting

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.Verified reviewerJob location: N19 Professional delivery
