Chris Fout was amazing. No BS kinda guy. Definitely the best salesman I've had the pleasure of speaking with. He was very informative and gave me the info I wanted to hear and the info I didn't like hearing lol. He never tried to hide anything and was upfront and honest. If you need windows and doors ask for this guy. He didn't waste my time with filler conversation and didn't push us to make any hasty decisions. I wish all salesmen where Chris.
