Sample Mold Testing
What a real mold test documents
This is a home in Kennett Square, Chester County. The owner had visible mold in the basement and water-stained ceilings on two floors and wanted to know: was it in the air they were breathing? Bob documented the visible conditions and took an air sample the same day.
Read the full case study: A Kennett Square Home With Visible Basement Mold: What the Air Test Actually Showed
Visible mold on the basement foundation walls
Dark, heavy mold growth in a basement stud bay above a pipe run, the classic pattern of growth concentrating low on the wall, where moisture collects and lingers. Documented with the exact location and extent, not just noted as "mold present."
Water staining and efflorescence: the moisture history
Dark water staining on the painted block foundation wall, plus efflorescence (the white chalky mineral deposit water leaves behind pushing through masonry). Together with active growth, this told the story of a wall that had been getting wet repeatedly, not a one-time spill.
Recommendation: remediate regardless of the air result
Per EPA guidance, any area of mold discoloration roughly 3ft x 3ft or larger should be professionally remediated. Bob's recommendation named the specific contractor action (qualified remediator), the moisture fix (grading, gutters, dehumidification), and the 24-hour window for repairing any active leak.
Sample Air Quality Testing
What a real air quality lab result looks like
Air quality testing is the lab half of the mold job above: the same visit, same PRO-LAB accredited lab, a different question. Instead of "is there visible mold," it answers "is it in the air right now." Bob sampled the HVAC central return duct, where the air handler pulls air from the living space, and took a same-day outdoor control sample for comparison. An indoor number means nothing on its own; it only means something next to what's in the outdoor air that same day.
A clean air result doesn't erase visible mold
This is the finding homeowners find counterintuitive: the air sample came back not elevated (107 spores/m³ indoors vs. 290 spores/m³ outdoors), but there was still clearly visible mold on the basement walls. Air testing measures the air at the moment of sampling. It doesn't remove a mold source or guarantee tomorrow's reading matches today's. Bob's report explained both results plainly, and the remediation recommendation held regardless of the air number.
Spore type identification and health relevance
Every report includes what each spore type is, where it's commonly found, and its health relevance, not just a spore count. Penicillium/Aspergillus, the dominant spore type here, is a common Type I allergen linked to asthma and hypersensitivity reactions in sensitive individuals.

Common Questions
Sample report: what homeowners ask Bob
Will my actual report look exactly like this sample?
The format will be the same, with the same lab table, spore-type breakdown, and photo documentation, but the results will be specific to your property and your air sample. Every home is different, so your report reflects what's actually in your air and on your walls, not what's shown here.
Why are the name and address removed?
This is a real report from a real Greater Philadelphia-area property, shared with the client's information removed out of respect for their privacy. The findings, photos, and lab data are unedited and real; only identifying details have been taken out.
How fast will I get my own report?
Lab results typically come back in 2-3 business days. You get a full digital report with photo documentation and lab results directly from PRO-LAB, an AIHA-LAP accredited laboratory.
Do you offer combined home inspection and mold/air quality testing?
Yes. Many clients bundle a home inspection with mold or air quality testing on the same visit, since Bob is already on site. See a sample home inspection report, or call 610-348-6728 to ask about bundled pricing.
