Mold testing pairs a full visual inspection with two air samples - one indoor, one outdoor control - analyzed at our accredited lab partners. You get species identification, spore counts, and a Eurofins MoldSCORE™ that compares your indoor air to the outdoor baseline, all in a written report within 48 hours. For homes, rentals, and commercial buildings across LA, Ventura, and Orange Counties.
Mold testing is the lab-verified answer to a simple question: is the air in this building normal, or is something growing that shouldn't be?
A mold testing visit starts the same way a mold inspection does - a certified inspector walks the property, takes moisture readings, and documents the conditions with photos. The difference is what happens next: we collect air samples and send them to the lab, where the analysis turns "it smells musty in here" into measured data you can act on. Most testing visits include two air samples, one taken indoors near the area of concern and one taken outdoors as a control.
That outdoor control is the part that makes the numbers meaningful. Mold spores are in the air everywhere, indoors and out, so a raw indoor spore count on its own says very little. Comparing your indoor air directly against the outdoor baseline is what reveals whether your indoor levels are normal for the neighborhood or elevated in a way that points to active growth inside.
Here is where our testing stands out. Your samples run through Eurofins's MoldSCORE™ system, which compares your indoor air directly to the outdoor control and returns a single number on a 100 to 300 scale. A score under 150 reads as normal, 150 to 250 points to a moderate probability of indoor mold growth, and above 250 signals a high probability. The result is plain to read: a clear number that tells you whether your indoor air is normal or elevated, and by how much. Alongside that score you get species identification and spore counts per genus, mycelial fragment counts, pollen counts, and background debris ratings - the full picture, explained in plain language.
People use the two terms interchangeably, but they are different services. A mold inspection is a visual and moisture-based evaluation: a certified inspector identifies what can be seen and measured on site, for $249. Mold testing adds the laboratory layer - air samples, species identification, spore concentrations, and the MoldSCORE™ comparison - for $349, which already includes the full inspection plus two samples. Choose a mold inspection when a clear professional assessment of what is visible is enough; choose mold testing when you want documented, lab-verified results.

Every $349 mold test covers the full on-site inspection, two lab-analyzed air samples, and a written report - whether it's a studio apartment or a 4,000-square-foot home.
Time on site: 60 to 90 minutes for most homes.
Format: Adjuster- and contractor-ready PDF.
Best for: Hidden mold, health symptoms, or documented results.
Your test is run by a certified mold inspector who works to a recognized industry standard, and your samples are analyzed by Eurofins (AIHA-LAP accredited, ID #173068) and BTLS (ASTM-standard methods, Tarzana). You get independent, lab-verified findings, documented with data, so you can act on the report with confidence.
$349 flat for standard mold testing - the full inspection, two air samples, lab analysis, and the written report are all included. The price you're quoted is the price you pay.
The mold testing cost is $349 for a standard home, and that covers the on-site visual inspection, two air samples (one indoor and one outdoor control), lab analysis with species identification and spore counts, the Eurofins MoldSCORE™ comparison, and your written report within 48 hours. Additional samples are $85 each when more areas need coverage, and larger homes or commercial buildings are quoted before you book so the number is clear ahead of time.
The most common reasons people ask "how much does mold testing cost" are persistent musty odors, ongoing health symptoms, a recent water event, or documentation for an insurance claim or real estate transaction. In each case, two well-placed samples plus the MoldSCORE™ comparison usually answer the question - and when the situation calls for more coverage, the $85 additional samples keep the total reasonable while still standing up to scrutiny.
