Mold Damage Remediation in Portland & the Portland Metro
The Portland metro is one of the mold-friendliest climates in the country. Nine months of wet-season rain, vented crawl spaces sitting on saturated Willamette Valley soils, and thousands of pre-1950 homes with plaster-and-lath walls create ideal conditions for indoor mold growth. Most calls we get are reactive: homeowners smell something musty in a basement, spot staining behind baseboards, or fail a real-estate inspection.
Our IICRC-certified Applied Microbial Remediation Technicians (AMRT) follow the IICRC S520 Standard for Professional Mold Remediation. We do not just remove visible growth. We identify the moisture source, contain the work area to prevent cross-contamination, and verify clearance after remediation.
We offer a free mold inspection across the Portland metro. Because we do not perform our own clearance testing on projects we remediate, you avoid a conflict of interest. When third-party testing is required, we recommend an independent industrial hygienist.
- Free mold inspection across Portland, Beaverton, Hillsboro, and Vancouver WA
- Containment with negative-air HEPA filtration
- Safe removal of contaminated materials per IICRC S520
- Antimicrobial treatment of all surfaces
- Moisture-source identification and repair

Common Causes
What causes mold damage remediation in Portland homes
Vented crawl space humidity
Portland crawl spaces routinely run 75 to 90 percent relative humidity during wet season, well above the 60 percent threshold where mold thrives on joists and subfloor.
Undetected slow leaks
A pinhole supply line, failed shower pan, or roof flashing leak can feed mold in a wall cavity for years before becoming visible.
Improper bathroom ventilation
Bath fans that vent into attic space rather than outside deposit moisture into insulation and dry to mold growth in Portland's damp climate.
Roof leaks and moss lift
Northwest moss lifts shingles, letting wet-season rain saturate attic decking and insulation.
Window and single-pane condensation
Original wood windows in older Portland Craftsmans drip onto sills and frames every winter.
Basement seepage
Perimeter drains that fail during atmospheric river events push chronic moisture into finished basements throughout SE, NE, and North Portland.
Warning Signs
How to tell you have a problem
- Visible black, green, white, or pink growth on walls, ceilings, or framing
- Persistent musty or earthy odor, especially near the crawl-space hatch
- Worsening allergy or asthma symptoms while at home
- Discoloration on drywall or behind furniture against exterior walls
- Peeling paint, bubbling wallpaper, or soft baseboards
- Recent water damage that was not professionally dried
What To Do Right Now
Before our crew arrives
- 1
Do not disturb visible growth
Brushing, scrubbing, or bleach-spraying mold releases millions of spores into the air and spreads the problem.
- 2
Reduce humidity
Run dehumidifiers and avoid adding moisture. Vent showers, run bath fans 30-plus minutes after bathing, and do not use humidifiers indoors.
- 3
Contain the area
Close doors to affected rooms. Avoid running HVAC if growth is near returns.
- 4
Find and stop the moisture source
Mold cannot grow without moisture. Removing growth without fixing the source guarantees it returns.
- 5
Get a free inspection
Visible growth larger than 10 square feet, or any growth from a Category 3 water source, requires professional remediation per IICRC S520. Our Portland inspection is free.
How It Works
Our Process
- 1
Free inspection
We inspect the growth, identify the moisture source, and provide a written scope at no cost.
- 2
Contain
Seal the area with poly and negative-air HEPA scrubbers to protect the rest of the home.
- 3
Remove
Safely demo and bag affected materials per IICRC S520 standards.
- 4
Treat and verify
Antimicrobial application and post-remediation verification.

Professional Equipment
The equipment we bring on every job
Consumer-grade tools won't reach professional dry standard or meet industry remediation requirements. Our crews arrive fully equipped from a Portland-based fleet - no waiting on rented gear from out of town.
- Negative-air HEPA filtration scrubbers
- Six-mil polyethylene containment with zipper doors
- Personal protective equipment (full-face APR, Tyvek)
- HEPA vacuums certified for microbial work
- Moisture meters and infrared cameras
- EPA-registered antimicrobials and biocides
- Soda blasting and damp wiping for framing decontamination
Standards & Certifications
Held to documented industry standards
All projects follow the IICRC ANSI/IICRC S520 Standard for Professional Mold Remediation and reference the EPA's mold remediation guidance. We do not use bleach as a remediation tool. The EPA does not recommend it on porous surfaces, and IICRC S520 does not list it as an effective mold remediation product.
Local & Independent
Why Portland homeowners choose a local restoration team
Portland housing stock is unique. Pre-war NE Portland Craftsmans and Foursquares, mid-century Beaverton and Milwaukie ranches, and newer Bethany, Bull Mountain, and Happy Valley subdivisions all have characteristic moisture issues we see weekly.
We know which inner Portland neighborhoods sit on high water tables, which 1990s builders vented bath fans into attics, and how proximity to the Willamette and Columbia rivers affects basement humidity in Sellwood, St. Johns, and downtown Vancouver WA.
Insurance & Pricing
Direct insurance billing - and what to expect on cost
Mold caused by a sudden, accidental, covered loss (a burst pipe, a broken supply line) is typically covered up to a sub-limit. Long-term crawl-space humidity, deferred maintenance leaks, and flood-source mold are usually excluded.
We document the moisture source carefully, which often makes the difference between a covered and denied claim.
Typical project ranges
Small contained mold remediation jobs in the Portland metro (one bathroom, a closet) start around $1,500. Full crawl space remediation with vapor barrier replacement typically runs $4,000 to $9,000. Large basement or whole-house projects with significant containment and demolition can reach $10,000 to $25,000-plus. We provide a written scope after our free inspection.
