Jeremiah Fields2023-05-17Trustindex verifies that the original source of the review is Google. I don't even have the words. We reached out to a few contractors after wind damage to siding, got a few quotes for full-house replacement vs repair, but Weiss was different. Jeff made sure we had peace of mind right away. He took the time to explain the steps of good installation and gave a fair assessment of my existing siding. I felt like I had what I needed to make an informed decision. Frankly, if I need something that he offers from here on out, I'm just shooting him an email. Thank you, Jeff.Google rating score: 5.0 of 5, based on 1 reviews
