Bill advised us well on our choices for new windows and had them installed promptly, professionally, and with an impeccable clean up. We had also asked Bill about replacing our storm windows. To both our surprise, it turned out he had installed them decades earlier (we just bought the house). Instead of selling us new windows, he showed us that they were placed in the window incorrectly and told us that these windows, although old, are excellent and do the job as well as any new one we could get on the market today. Bill is an honest business man who really knows his product and he works for his customers. He did this work for us last year, and this year we hired him again. A pleasure doing business with Bill!
