Prefab Home Moisture Issue
Hi everyone,
I recently inspected a prefabricated home and found no significant issues. About a month later I received a call from the home buyer stating that there was moisture damage all over the house. I took a second trip to the property to try and get some answers for my customer. Sure enough, some of the walls had turned into bread pudding. I was in a state of near disbelief. I went back onto the metal roof and found no apparent defects. There is no attic access therefore I was unable to completely verify that there was no roof leak, even though I saw no stains on the ceiling. I went under the house and found no suspect plumbing. The only thing I can think of is when I initially inspected the house, the HVAC return filter was completely saturated and the customer still had not changed the filter. (It doesn't look like it's been changed in over a year). My moisturizer meter did pick up high levels of moisture around the ducts and registers but that just seems bizarre that the AC could do that much damage to the interior walls. Has anyone else had this experience? I'm at a loss here.
