I dont know if im being overly suspicious. We moved in 5 years ago and do plan to get new windows fitted one day. We mentioned it in passing then lo and behold last week we get a knock at the door from anglian windows. A cold call, we did not contact them for a quote which just doesnt sit right with me. He produced ID and my husband gave him his details to get a quote sorted one day. They call today and say theyll come at 12 to do the quote. At about 11 i happened to look out our front window and a guy is smoking looking at our house. Turns out it was the guy to give the quote, he was very early. Its our first house, fist life. Is this normal? Why would a reputable company be knocking on doors randomly? AIBU to be suspicious?
