    The men who came to install the windows were very professional and cleaned up afterwards. We were called from a painting person and I hadn't read my papers as well as I should, and he wanted to come do the painting and I told him I didn't think it was in the contract because the first windows we had installed I had to do all the varnishing on them, so after I read my contract again, it did say they would come and paint, but that was my error not yours.

    This is the third time Randy has installed windows or patio doors for us and did an excellent job every time. Randy works as if it is his own house and I will recommend him and Andersen products every time.
