Chris arrived on time. He was very professional and personable. He took his time explaining about the windows and doors and there was no hard sale. We ended up buying few casement windows not thinking we would but there was a 25% off discount being offered and I was happy to find out about the unlimited lifetime warranty. Chris did a great job!
