A faint smell inside the house seemed like the kind of everyday nuisance many homeowners try to ignore. But when it did not fade, and instead began spreading through the home, one homeowner realized the problem was not going to solve itself.
The odor had no obvious source at first. Common possibilities such as plumbing, ventilation, and other household trouble spots were considered, but none of them explained why the smell kept getting stronger.
Eventually, the homeowner narrowed the strongest odor to one section of an interior wall. That detail changed the situation from a general household annoyance into a focused investigation.
The Source Was Hidden Out of Sight
After checking the usual areas without finding an answer, the homeowner carefully opened part of the wall to see what was behind it.
