      Sash Window Wizards did a great job: the quality of the double glazed acoustic glass windows installed was very high, and my living room is now a lot warmer and sound proof as a result. Special thanks to Andrew and his colleagues!

    • Replacement of Sash Windows

      10Verified Review

      Andy Williamson replaced the three original sashes in a bay window of a Victorian terraced property with modern, double glazed units. I have used Andy's company over a number of years and, as previously, he did an excellent job, providing a high quality product at a fair price.

    • Two bathroom windows replaced


      Andy removed two wooden single-glazed windows and replaced them with two wooden double-glazed windows, one a sash window and the other a small casement. He made an excellent job of them, and before starting work he covered up any areas that could become dusty and when he finished his work he vacuumed any floor and carpets that needed it. He went about the work very efficiently, was cheerful, began work on the date that he said he would, and was always on time. My wife and I would strongly recommend him to anyone.

    • Three double glazed sash windows installed


      The whole service was excellent. The windows are beautifully made, work perfectly and installation couldn't have been quicker.

    • Replaced a round window.

      10Verified Review

      Andy replaced and glazed a round window. Did a very careful, neat job, with a high quality finish. He gave good advice leading up to the work and was flexible on how best to do it, as well as very accommodating in fitting me into his schedule. I have used Andy previously to replace several sash windows and both the workmanship and how he deals with the customer are first class. I would highly recommend.
