"What you breathe inside your home matters. Bradley & April Wilburn — both SC Licensed Home Inspectors — perform professional indoor air quality testing across Greenville and the Upstate, with samples analyzed by an independent accredited laboratory."
Most people think about air pollution as something that happens outside — smog, traffic exhaust, industrial emissions. But the EPA estimates that indoor air can be 2 to 5 times more polluted than outdoor air, and Americans spend roughly 90% of their time indoors. The air inside your home contains a complex mixture of mold spores, pollen, pet dander, dust mite allergens, volatile organic compounds (VOCs) from cleaning products and building materials, and particulate matter from cooking, smoking, and outdoor air infiltration. For most people, these levels are unremarkable. For some homes — especially older ones, ones with crawlspaces, or ones with hidden moisture problems — indoor air quality can be a real concern.
Bradley Wilburn (SC Licensed Home Inspector #48751) and April Wilburn (SC Licensed Home Inspector #48528), the husband-and-wife team behind Carolina Quality Home Inspection, perform professional indoor air quality testing across Greenville and the Upstate. We have been testing Upstate-area homes since 2013 — for homebuyers in active real estate transactions, for current homeowners worried about visible mold or unexplained allergy symptoms, and for sellers wanting to document the air quality in their home before listing. Air quality testing can be performed on its own or scheduled together with a general home inspection.
The Upstate's climate makes indoor air quality particularly worth thinking about. The region's humid subtropical summers, combined with older housing stock that often has crawlspaces, retrofitted HVAC, and limited vapor barriers, creates conditions where elevated mold spore counts and humidity-related air quality issues develop quietly over time. Visible water damage, musty smells, persistent allergy symptoms when home, recurring respiratory irritation, and recently flooded basements or crawlspaces are all reasons to consider professional testing. Sometimes the test confirms everything is fine — which is valuable in itself. Sometimes it documents a real problem that's been hiding behind a closet wall or under a subfloor.
Carolina Quality's air quality testing uses calibrated air pumps to capture spore samples and surface lift-tape samples for visible suspect materials. All samples are sent to an independent accredited laboratory for analysis — we don't analyze our own samples, which keeps the results unbiased and credible. The lab report identifies specific mold species and concentration levels, and we deliver a plain-English summary explaining what the lab numbers mean for your specific home.

Upstate South Carolina's humid subtropical climate creates conditions that favor mold and microbial growth — long humid summers, mild winters, and significant rainfall throughout the year. Combine that climate with the region's older housing stock — historic homes in Greenville's Hampton Heights, Spartanburg's Hampton Heights/Converse Heights, mill village cottages in Greer, Easley, Anderson, and Spartanburg, and 1980s-90s subdivisions where original HVAC systems may be near end-of-life — and you have homes where indoor air quality concerns can develop quietly.
Common Upstate triggers for testing: visible mold or staining, musty smells that don't go away, persistent allergy or respiratory symptoms only when at home, a recently flooded crawlspace or basement, an older HVAC system that may be circulating contaminated air, or simply peace of mind for a buyer who wants to know what they're walking into. Testing gives you data — not guesses.
Calibrated air pump samples taken from the area of concern (basement, crawlspace, living area, etc.) to capture airborne mold spores for laboratory analysis.
A baseline outdoor air sample taken at the same time, so the laboratory can compare indoor levels to natural outdoor levels — the only way to interpret indoor results accurately.
If we observe visible suspect material — staining, growth, or discoloration — we can take surface tape-lift samples for laboratory identification of the specific mold species present.
Samples are sent to an independent accredited laboratory. We don't analyze our own samples — keeping our role as inspector separate from analysis preserves the credibility of the result.
When the lab returns the technical report, we deliver a plain-English summary explaining the species identified, the concentration levels, and what the indoor-vs-outdoor comparison means for your home.
Beyond the samples themselves, we visually inspect the areas where samples were taken — looking for moisture intrusion, ventilation issues, and source conditions that may explain elevated readings.
Call or text us with the property address, areas of concern, and your timeline. Most Upstate air quality tests can be scheduled within a few business days.
Bradley or April collects air samples from the areas of concern plus an outdoor control, and takes any surface tape-lift samples needed. On-site time is typically 30-60 minutes.
Samples are shipped overnight to an independent accredited laboratory. Lab turnaround is typically 3-5 business days for the technical analysis.
Once the lab report arrives, we deliver a plain-English summary explaining the findings and what they mean for your home — typically within 24 hours of receiving lab results.
We don't analyze our own samples. Independent accredited laboratory analysis keeps the results unbiased — the same lab whether we love your home or have concerns about it.
Bradley and April are both SC Licensed Home Inspectors. Two perspectives, two sets of eyes evaluating moisture, ventilation, and source conditions during sampling.
Lab technical reports are dense. We translate them into clear summaries explaining what the species and concentration levels mean for your specific home — no jargon, no scare tactics.
Answers to the most common questions Upstate homebuyers and homeowners ask about indoor air quality testing.
Common reasons include visible mold or staining, persistent musty smells, recurring allergy or respiratory symptoms that improve when away from home, a recently flooded basement or crawlspace, evidence of historic water damage, an older HVAC system you suspect may be circulating contaminated air, or simply wanting documented baseline information about a property you're buying. Testing gives you data — not guesses.
On-site sampling typically takes 30 to 60 minutes depending on how many areas need testing. Samples are then sent to an independent accredited laboratory, which typically returns results in 3 to 5 business days. We deliver our plain-English summary within 24 hours of receiving the lab report — so total turnaround is typically about a week from sampling to final report.
The lab report identifies the specific mold species present in your samples and the concentration levels (typically reported in spores per cubic meter). The indoor-vs-outdoor comparison is critical — outdoor air always contains some level of mold spores, so indoor results are interpreted relative to that baseline. We deliver a plain-English summary explaining whether your readings are elevated, normal, or indicative of an indoor source that warrants further investigation.
Elevated readings don't automatically mean disaster. Sometimes they point to an obvious source (a recently flooded crawlspace, a leaking HVAC condensate line, visible bathroom moisture) that's straightforward to address. Sometimes they warrant follow-up by a licensed mold remediation contractor. We don't sell remediation services — our role is to identify and document, then explain your options.
