I contacted Andy about 5weeks ago and he came and gave me a quote almost immediately. I also discussed with him some previous windows that had been installed by National Company. He explained why they had failed and why his fitting and fitments were of a superior quality. I then arranged a mutual date for him to fit my three windows. He was on time and the windows went in without a hitch, we are both extremely happy with the product and service. We have asked Andy to come around this weekend to give us some quotes for a Conservatory Upgrade and some other general building work.
