I had a few quotes for renovating my period sash windows. I’m glad I chose Jon’s company. They did an excellent job turning windows that were in a desperate state to be smooth and draft-free. The system Jon installed allowed for easy access to the windows for cleaning and painting inside and out. Really impressed at how Jon’s team carried out the major renovation and meticulously cleaned during the work. Very competitive price and money well spent.

Jon did an excellent job of replacing my sash windows within the original frames, giving me double glazing whilst honouring the architecture of my house and maintaining the original stained glass. He was reliable, clean workers and a real pleasure to have in my home. And I hate having people in my home!! Last year he returned to remove parts of the sills where they were starting to rot and cut in new wood. You can't see the joins and he actually came in below his quote because he didn't need to do as much work as he had first thought. Honest, skilled and reliable. Can highly recommend.

I contacted Jon as the sills of my sash windows needed some attention. We had the option of replacing or repairing the sills. On examining the windows Jon gave his honest opinion and concluded that the sills were in pretty good condition apart from a few small rotted areas. In his view the window sills needed some attention in terms of stripping the existing paint, filling some rotted wood and painting with a quality oil based paint. A few more years could be achieved from the existing windows without undertaking a major overhaul. I appreciated his honesty - and, clearly, he possessed significant knowledge and experience on sash windows. I will certainly contact Jon again when the windows require further attention and more major work.
