From the books — a recent Portland job
Got a call last month from a the south Portland home — any era; older homes more vulnerable build. Symptom: black mold growing on drywall behind a wallpapered bathroom. Cause: slow leak from a shower valve had been wetting the drywall for 18+ months. S520 containment, removed all affected drywall and tile substrate, treated framing with antimicrobial, post-remediation verification testing passed, all done in before lunch, billed flat-rate at $220.
What you're paying for
Mold work follows IICRC S520 protocol: contain the area first to prevent spore spread, then remediate. Skipping containment is the #1 mistake unlicensed mold contractors make.
We set up plastic barrier walls around the affected area, run negative air pressure with HEPA-filtered air scrubbers (typically 4-6 air changes per hour), and the crew works in PPE inside the contained area.
Visible mold growth on porous materials (drywall, carpet, padding, fabric) is removed and bagged. Hard surfaces are HEPA-vacuumed and treated with EPA-registered antimicrobials.
After remediation, we run post-remediation verification (PRV) testing — usually third-party — to confirm the affected area returns to baseline.
How Portland jobs differ
If you're inside the city limits, we're typically there inside an hour during business hours. Outside the metro, plan on a bit longer.
On bigger jobs we'll bring two techs. On simpler ones, just one — fewer hands, faster billing.
