Nick was recommended to me at work by a friend, he worked on our grade II listed home in Camden, and I honestly cannot recommend him enough. It was a big project and he was with us a few months restoring our original sash windows.

It was a big project and he was with us a few months restoring our original sash windows. You can tell he takes pride in his window work. I can now lift my sash windows up really easy with one finger, they feel like new windows. Delighted with results.
