Why Clark County homeowners call us
A musty room, a past leak, or a home you're about to buy.
Mold and moisture
Crawl spaces, damp winters and slow leaks are common sources. Room-by-room mold readings show where airborne mold is elevated, and the Deep-Dive adds moisture metering and thermal imaging to help trace the water.
Newer, tighter homes
Energy-efficient construction holds onto what's inside: VOCs from new finishes and furniture, carbon dioxide from occupancy, and humidity. We measure all three in every room.
Buying a home
Air testing fits inside most inspection windows. Add radon for $99 if you want a 48-hour radon reading too; tell us your contingency date when you call.
Local and independent
Your neighbors in Ridgefield. Not a remediation company.
Jim and Michele spent years in home inspection and water restoration before founding illumenair. We only test. We don't sell remediation, so there's no sales pitch behind our findings. If your home needs work, the report gives you clear documentation to hand any contractor you choose.

How much does mold and air quality testing cost in Vancouver, WA?
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 you test during a home purchase?
Usually, yes. Air results are reviewed on site and the written report follows within 48 hours. Radon, a $99 add-on, needs a 48-hour monitor and a return visit, so tell us your contingency date when you call.
Will you find where the mold is coming from?
Room-by-room readings show which areas are elevated compared to the outdoor air and the rest of the house. The Mold & Moisture Deep-Dive adds moisture metering and thermal imaging to help trace a suspected water source. We can't guarantee a source will be found.
Do you do mold remediation?
No. We test only, so our findings are independent. The report gives you documentation to share with any contractor.
