    A team member at WestPro visited my home and gave me an honest assessment of our siding. She suggested a few repairs but overall told me that our siding was in good shape for a number of years. She asked us to call WestPro when that time comes. I never had the sense that she was trying to make business where there was none. They seem like an honest company from this interaction.

    WestPro completed roof and siding repairs on 2 of the units at our property. They were very responsive, timely and did great work. Beck, with WestPro, was on-site to do the final walk-through when they had completed the work and he was thorough in explaining what had been done and conscientious of making sure any/all of our questions were answered.

    I can’t say enough great things about WestPro and the siding/roofing remodel on my home. My home had aged vinyl siding which was faded, brittle and diminished my home’s value. The option to go with Hardie siding was a no brainer because it’s the toughest material available, which at our elevation combined with yearly hail storms is a necessity.
