Testing Methods — Portland, OR

Matching the Right Test to Your Portland Situation

Each method below produces different data. We explain which is appropriate for your Portland, OR property situation before you commit.

Non-Viable
💨Spore Trap Air Sampling
Spore trap cassettes collect all airborne particles — viable and non-viable — and are analyzed under microscopy for mold genus identification and spore concentration. Results typically return in 24–48 hours from an accredited lab. Compared against an outdoor baseline, this data shows whether indoor spore counts are elevated and which genera are present. Standard method for routine Portland, OR residential and commercial air quality assessment.
Viable
🏭Viable Culture Air Sampling
Viable culture plates capture live, culturable mold spores that grow on culture media — allowing species-level identification and colony-forming unit counts. Results take 5–7 business days but provide species-level data that spore traps can't. Used when species-level identification matters: Stachybotrys confirmation, occupational health documentation, or situations where genus-level data from spore traps isn't sufficient for your Portland, OR use case.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface sampling confirms whether visible discoloration in your Portland property is actually mold (not staining or efflorescence) and identifies the species present — affecting which removal protocol and PPE level is appropriate.
ERMI
🔋ERMI Floor Dust Sampling
ERMI provides a historical record of mold accumulation — not just what's airborne right now. Useful in Portland properties where symptoms are present but spore trap sampling comes back normal, or for verifying long-term post-remediation success.
HVAC
🏢HVAC Register & Return Air Testing
Register-versus-room comparative sampling confirms whether your Portland, OR HVAC system is a mold amplifier. Knowing before spending on duct cleaning whether cleaning will actually help is worth the testing cost.
Clearance
📄Post-Remediation Clearance Testing
Independent post-remediation testing compares treated zone air samples to outdoor baseline — confirming indoor spore counts returned to acceptable levels before re-occupancy. Our Portland, OR clearance testing uses the same accredited lab protocol as pre-remediation sampling, producing directly comparable data that demonstrates the remediation achieved its objective.

Client Reviews

What Portland Clients Say About Our Testing

★★★★★
Pre-purchase ERMI testing on a Portland, OR home we were considering. Results showed historical Stachybotrys accumulation in the basement that the seller hadn't disclosed. We used the written ERMI report to negotiate a remediation credit. The test cost $400 — the credit was $8,500.
Thomas B.
Portland homebuyer
★★★★★
Our office building in Portland, OR had occupant health complaints. Standard spore trap testing came back slightly elevated but not definitively actionable. Cheap Mold Removal recommended HVAC register-versus-room comparative testing — found dramatically elevated counts at two supply registers compared to the rooms they served. Confirmed AHU contamination. That targeted approach was exactly what our facilities team needed to justify the HVAC remediation budget.
Linda A.
Property manager, Portland, OR
★★★★★
Real estate deal — seller's disclosure showed 'no known mold.' Cheap Mold Removal's pre-purchase testing found elevated Cladosporium and Penicillium counts in the crawl space zone. Written report was used to require remediation as a closing condition. The test results were accepted by both the seller's agent and the seller's attorney without dispute.

Frequently Asked Questions

What Portland Clients Ask About Air Quality Testing

Spore trap: fast (24–48hr), genus-level ID, quantified concentrations. Viable culture: slower (5–7 days), species-level ID, CFU counts. Most routine Portland testing starts with spore traps. Viable culture is ordered when the specific question requires species confirmation.
Consumer kits detect presence, not concentration — and they grow positive in nearly every environment. For any situation where results need to support a decision (insurance claim, real estate transaction, remediation planning), accredited lab analysis via calibrated air sampling is the required standard in Portland, OR.
Minimum two indoor plus one outdoor comparative. Additional samples per floor, zone, or HVAC register depending on the scope of the question. We tell you specifically how many are warranted for your Portland property before booking.
Non-viable spore trap results from our accredited lab partner typically return in 24–48 hours from the date of sample receipt. We ship samples same-day in most cases, so most Portland clients receive their written report within 3–5 business days of the testing appointment. Viable culture takes 5–7 business days. ERMI takes 5–10 business days. Rush processing is available from some labs for time-sensitive situations — we can advise on availability.
Testing data is one input into the remediation decision. Significantly elevated indoor counts above outdoor baseline, presence of high-concern genera, and visible growth are the primary factors. We provide written interpretation and specific recommendations with every Portland, OR test report — you have the data and our analysis to make an informed decision.
