Mold Testing

Same-day and next-day appointments are usually available across our Corona service area, with 24/7 emergency response for active leaks, recent water damage, or urgent real estate timelines. Standard scheduling runs 1 to 3 business days depending on availability.

Our certified mold inspectors assess bathrooms, kitchens, laundry rooms, basements, attics, crawl spaces, HVAC components, and any area showing signs of past or current water issues. Thermal imaging and moisture meters identify hidden moisture behind walls and under floors.

The master-planned communities of South Corona, Chase Ranch, and Eagle Glen share a construction era — roughly 1990 to 2010 — that is associated with a specific and well-documented set of mold-related building deficiencies. HVAC systems installed in homes of this era were sized under energy codes that prioritized cooling capacity over moisture management, leading to systems that frequently short-cycle in mild weather and fail to adequately dehumidify indoor air. Builder-grade vapor barriers used in slab-on-grade construction during this period have aged unevenly and in some cases have been found to underperform their design specifications. Stucco exterior finishes, the dominant cladding in this era of Southern California construction, are highly sensitive to improper installation of control joints and flashing details — deficiencies that were common in the fast-paced construction environment of the 1990s growth boom and that allow chronic moisture intrusion behind the stucco at cracks and penetrations.

Pricing varies based on the size of the property, the scope of testing required, and whether any lab work is included. Most residential mold inspections in Corona fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
