So we just had a 40x60 pole barn put up on October 17,2023. We told the contractor that we would like a ceiling but we wouldn’t be putting in a concrete floor or insulating for a year or so. He suggested we put the ceiling up while he is there with the lift. So we agreed to have him add that to the build. The day before he was to build he asked us if we wanted him to tyvek the barn. He said that he knew we wanted to insulate it at some point and he thought it would be better to have the tyvek on, We agreed. So we went to the barn to check on it and there’s a good amount of mold everywhere. Come to find out the contractor tyvek around the perlins which left the barn with no way to breathe. I have contacted the contractor and all he has said was he has never heard of anything like that happening and he’d call of couple places. And now he won’t get back to me. Is he responsible? And what could have caused this? Is it because of not having ventilation?
Moisture is definitely a big issue in pole barns, and trapping it inside will cause mold fast. Ventilation is key, but before doing anything major, it’s worth running Mould Tests to see what you’re dealing with. Sometimes it’s worse than it looks, and other times, it’s just surface-level stuff. If it turns out to be a bigger problem, at least you’ll know exactly what steps to take next.
