This was a big surprise and let down. The company sent men who were not experienced or not supervised. They kept walking in my raised garden beds (which were not covered with a tarp) nails & screws were dropped in my garden & not picked up. They did not install the right vent, they broke our kitchen vent, They failed to use a gutter guard on their ladder so they damaged our almost new eves trough. They sent a company who did not replace our eves trough with the same quality that we had up. That company was rude and put their ladder in our gardens and currant bushes. It was a train wreck.
