Have lived in this modular for 23 years, with no obvious troubles. After talking with a rep at "Shipshewana on the Road" at the Summit in Lansing: Jamison Betz. I realized it would be a great home improvement. Chris Murray visited, we both went into the crawl space. With his talk I was convinced. Along came Doug and his crew, fine job.
I used Ayers Basement Systems because of their reputation.
