Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
