We already knew that we had an insulation issue. We actually set the appointment for siding, but they brought up that our insulation needed to be done before siding. This made us feel comfortable that they weren't just trying to sell us what was in their best interest, but that they're concern was OUR best interest. Their prices were similar to others that quoted us and their product and warranty was much better. They have done a fantastic job and we would recommend them.
