Reno’s high-desert climate might make mold seem like an unlikely problem. Outside, the air is generally dry. Inside a building, however, one persistent moisture source can create a completely different environment.
A slow plumbing leak behind a wall, a roof leak that goes unnoticed, condensation around an HVAC system, or moisture collecting in a crawl space can provide enough moisture for mold to grow.
Seasonal conditions can contribute as well. Snow and Sierra snowmelt can introduce moisture around foundations and crawl spaces, particularly when drainage isn’t moving water away from the property effectively.
Once mold establishes itself, simply wiping down the visible area doesn’t necessarily solve the problem. The moisture source and affected materials have to be addressed as part of the remediation process.
