Probably one the best experiences we've had with a building contractor/supplier. We went to the showroom where we were given all the information we needed and shown the various options for our kitchen patio doors. We selected what we wanted and gave the dimensions and by the time we got home, there was a plan and an estimate in our inbox.

I cannot recommend Lightfoot highly enough. I used to run a business, and the sheer pleasure and relief of being communicated with properly and courteously means a lot. It’s rare these days. The windows and installation were excellent. Reece, Grant & Bradley were fantastic. Particularly as they were up against supply issues, parking restrictions not to mention Covid.
