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.

We have used Lightfoot Windows on two occasions now, and both times their service has been exemplary. The products we purchased are also of a very high quality and we are really happy with them. The surveyors and installers were careful, considerate and polite. We highly recommend Lightfoot Windows and will definitely use them again should the need arise.

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.
