Air Testing

Mold air testing detects airborne spores and assesses indoor air quality, even in spaces where no visible contamination has shown up yet.

Overview

Why mold air testing matters

Most mold is invisible. Spores float undetected through ducts and doorways, spreading from room to room with the air itself. Air testing reveals the species and concentration of what's airborne, even when no visible growth is found on any surface.

Mold air testing detects:

  • Invisible mold spores circulating through the air
  • Differences in spore levels from one room to the next
  • Contamination inside HVAC systems and hard-to-reach areas
  • Early warning signs in rooms that appear unaffected

Benefits

What you get from air testing

Understand the air quality and find what your eyes can't

  • Non-invasive: No drilling, no surface damage, no demolition needed.
  • Early detection: Catch contamination before it spreads or symptoms start.
  • Data-driven: Measure and compare spore counts room by room with lab-verified results.
  • Defensible documentation: State-certified lab results that hold up for insurance and real estate use.

About

How mold air testing works

Our certified mold inspectors use calibrated sampling pumps to draw air through a spore trap cassette, capturing airborne mold spores. The lab identifies the mold species under a microscope, including any HVAC contamination if the system is implicated.

Our process includes:

  • Targeted sampling in problem areas and comparison sampling outdoors
  • Spore traps or impactor cassettes calibrated for accurate collection
  • Lab-verified results identifying species and spore counts
  • A written mold inspection report with the numbers and next steps

Call For An Inspection
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.
