When the question is your health
Data you can take to your doctor.
Mold is the concern we hear about most in Portland, and it's usually tied to how someone feels at home. Our assessment measures airborne mold in each room alongside bacteria, VOCs, fine particles and carbon dioxide, and compares every reading to the air outside at the same time. That shows whether a problem is localized to a bedroom or basement, spread through the house, or not coming from the house at all.
The written report is formatted for your records and for sharing with a physician, naturopath or functional medicine practitioner. If your provider wants the mold identified to genus, we add traditional air canister sampling analyzed by an independent lab. We're not physicians and don't diagnose; we measure, so you and your provider can decide with real numbers. For medical providers
What we see in Portland homes
Older houses, below-grade spaces
Much of Portland's housing predates modern moisture barriers, with basements and crawl spaces over bare soil. Moisture that starts below can show up as elevated mold in the rooms above.
Long, damp heating seasons
Closed-up homes, condensation on cold surfaces and indoor humidity above about 60% create the conditions mold needs. We map humidity room by room so you can see where it collects.
Wildfire smoke and fine particles
During smoke events, PM2.5 readings show whether smoke is getting indoors and whether filtration is keeping up, room by room.

Portland indoor air quality testing questions
How much does indoor air quality testing cost in Portland?
A full-home assessment is $750 for homes up to 3,000 sq ft and $950 for 3,000 to 4,500 sq ft, with every room included and no per-room fees. Over 4,500 sq ft, contact us for pricing. Traditional air canister testing starts at $300.
Can testing help if I think my home is affecting my health?
It can show whether your home's air is a likely factor and where. We measure mold, bacteria, VOCs, particles and more in every room against the outdoor air, and the report is formatted to share with your doctor or naturopath. We don't diagnose medical conditions.
Do I need lab testing to identify the mold?
Usually not. If you're remediating, the fix is the same whatever the genus. If your doctor wants the mold identified to genus, add traditional air canister sampling analyzed by an independent lab.
Do you test for wildfire smoke indoors?
Yes. PM2.5 and PM10 are measured in every room, which shows whether smoke is getting in and where filtration is falling short.
