We aim for excellence with every job, and our reviews confirm it. Read how we consistently exceed expectations and deliver impeccable results.
Archie and Peter have done a fabulous job on the rotten sash windows of my Victorian maisonette - fully replacing the huge kitchen window and full restoration of the rear bedroom window, plus new tiny window to the bathroom. Taking pride in their craftsmanship, the results are excellent (and much better than another company who restored a landing window a few years ago!). Efficient, clean and tidy, with reasonable prices, I would highly recommend this company
