Musty smell
A musty, pungent odor could indicate a broken pipe or sink leak that has given rise to mold, which thrives in dark, damp spots.
When it comes to mold, those with allergies and asthma should be concerned when it comes to this home odor problem. Both conditions can be significantly aggravated by mold exposure.
If you notice any mold, be sure to disinfect non-porous surfaces such as tile with a 10% bleach and water solution and let sit for about ten minutes while ventilating. For porous surfaces, including drywall, it’s best to just replace them.
If you can’t see the mold, it might be in the walls, in which case, for this home odor problem, call your local health department or a home inspector to find the problem.
Lots of home inspector issues start with a smell in the house.
