Indoor Air Quality Testing
IAQ testing is built into the Comprehensive Environmental Assessment — VOCs, particulates, humidity, and biologicals run alongside the mold and moisture work. Not sold separately; it's part of the full evaluation.

Indoor air quality is a much bigger category than mold. VOCs off-gas from new furniture, adhesives, cabinetry, and cleaning products. Particulates come in from cooking, combustion, outside air, and HVAC performance. Humidity — too high or too low — drives biologicals (mold, dust mites) and respiratory irritation. Each of those is a different data point.
A real IAQ assessment measures what’s actually in the air rather than assuming it based on what the home looks like. We use calibrated continuous monitors for particulate matter, VOCs, and humidity over a representative window, and supplement with targeted lab sampling for biologicals where appropriate. Readings only matter in context — a spike at 7 p.m. every day tells a different story than a flat elevated baseline.
If you feel different in a home versus out of the home, you're on to something. That's usually the starting point for an IAQ engagement.

Features & Benefits
Multi-Parameter Scope
Multi-parameter measurement across volatile organic compounds, particulate matter, relative humidity, and biological contaminants — the real-world mix of what you're actually breathing.
Contextual Reporting
A plain-English report explaining each reading in context — baseline ranges, seasonal patterns, and what the numbers actually mean for the family living in the home.
Lab + Continuous Data
Lab-grade sampling methods paired with continuous in-home monitoring where the situation calls for it — not a single snapshot, but a real picture.
Health-Focused Lens
A family-first framing. Unexplained symptoms that improve when you leave the house deserve a thorough investigation, not a guess.
How It Works
Intake & Scope
We start with a conversation about symptoms, timing patterns, and what's changed in the home — new furniture, recent HVAC work, a renovation. The intake shapes which parameters get priority.
Multi-Layer Measurement
Continuous monitors capture VOCs, particulates, and humidity over a representative window. Lab samples are added for biologicals or specific compounds where the intake pointed us.
Plain-English Report
A written report explains each reading in plain English, compares it to outdoor baselines and reference ranges, and connects the numbers back to what you can actually change in the home.
What Our Clients Say
Frequently Asked Questions
Depending on the scope: volatile organic compounds (VOCs), particulate matter (PM2.5 and PM10), relative humidity, temperature, CO2 as a ventilation proxy, and biologicals including mold spores and bacteria. We pick the parameter mix based on symptoms, the home, and what the homeowner is actually trying to answer.
The on-site window is typically 2-3 hours for the walk and sampling setup. Continuous monitors run 48-72 hours minimum to capture a representative range. Lab results on biological or VOC samples usually return in 3-5 business days.
No — IAQ measurement is one of the components inside our Comprehensive Environmental Assessment. It runs in parallel with the mold, moisture, and other building-science work during the same visit. The full assessment is the engagement; IAQ is part of it.
Yes — IAQ testing is one of the eight components of our Comprehensive Environmental Assessment. Most clients get IAQ as part of the broader work rather than as a separate engagement.
Inside the Comprehensive Environmental Assessment
Inside a Comprehensive Environmental Assessment, IAQ measurement runs in parallel with the mold and moisture layers. One visit, one coherent environmental report that connects what's in the air to where it's coming from.
