Basement flooding is THE Portland restoration emergency. 70%+ of inner Portland homes have basements, and they flood from a half-dozen distinct scenarios. Same-hour Portland dispatch, IICRC-certified.
Here's what to do — and what not to do — in the next 5 minutes. The window between the loss starting and significant structural damage is short.
Portland basement flooding traces to six common scenarios. Each requires different protocols — knowing which one you're dealing with shapes the entire response.
Sustained heavy rain raises the water table around foundations. Foundation walls weep moisture; over hours, water enters through wall-floor joints, foundation cracks, or window wells. Most common Portland basement flooding scenario.
Many Portland basements have sump pumps to manage routine groundwater. When the pump fails — bad float switch, power outage, motor burnout, blocked discharge — water rises in the sump pit and floods the basement. Atmospheric river events often combine pump failures with peak demand.
Inner Portland's combined sewer system overflows during heavy rain. Sewage backs up through basement floor drains and lowest fixtures. Category 3 cleanup. Common in Sellwood, Brooklyn, southeast inner Portland.
Older Portland homes (Northwest District, Northwest Hills, Hawthorne, Sellwood, Mt. Tabor, Laurelhurst, Alameda, Irvington — 1900s-1950s construction) have original foundation walls without modern waterproofing. Seepage events present as slow accumulation through walls, often along specific seams.
Burst supply lines, water heater failures, washing machine hose failures, dishwasher leaks above the basement drain water through the ceiling and onto the basement floor. Category 1 (clean) versus the Category 2-3 of storm or sewer scenarios.
Basement window wells with failed drains or covers fill during atmospheric river events and dump water directly into the basement through the windows. Damage is concentrated near specific windows but extends through wall cavities.
Our IICRC-certified crew arrives with truck-mounted extraction, structural drying equipment, full PPE including Category 3 for sewer scenarios, moisture meters, contents pack-out supplies. In the first 60 minutes: water category determination, extraction begins, photographic documentation, contents triage, structural drying positioning, sump pump assessment.
Over 24-48 hours: extraction of standing water and saturated contents, demolition of unsalvageable materials (drywall below water line, carpet pad, insulation, baseboards, water-damaged framing), antimicrobial pre-treatment, structural drying with commercial dehumidifiers, daily moisture monitoring, coordination with adjuster.
We bill your insurance carrier directly so your out-of-pocket cost is typically just your deductible. We work with every major Oregon carrier including PEMCO and Country Financial — and high-net-worth specialty carriers for custom-home losses.
Same-hour dispatch to all of these Portland-area cities. Our crews are local — we know the neighborhoods, the watersheds, the construction patterns, and the carriers.
Depends on cause. Plumbing failures (burst pipe, water heater, supply line) above the basement: covered by standard homeowners. Sewer backup: covered by Sewer/Water Backup rider if you have it. Sump pump failure: usually covered by Sump Pump Failure rider if you have it. Atmospheric river groundwater/rainfall flooding: typically excluded from homeowners, requires NFIP. We document the loss for whichever coverage applies.
Common pattern: foundation seepage during sustained rainy weather, accelerated by inadequate exterior drainage. Solutions: French drains around foundation perimeter, sump pump installation/upgrade, gutter and downspout extension, regrading around foundation, interior wall drainage. After your current restoration completes, we can recommend qualified Portland-area basement waterproofing contractors.
For minor moisture: maybe. For standing water, sewer involvement, or extensive saturation: no. Residential dehumidifiers can't keep up with major saturation. Saturated materials inside walls and under flooring need to be removed and replaced; surface drying doesn't address what's inside the materials.
Mitigation (extraction, demolition, drying, antimicrobial): 7-21 days depending on water source and extent. Reconstruction (drywall, baseboards, flooring, contents return): 3-10 weeks. Total project usually 6-14 weeks.
Both are good investments for Portland basements. Backup battery sump pumps continue running during power outages; French drains capture water before it reaches foundation walls. Annual maintenance on sump pumps is critical — most failures happen because they weren't tested before the rain came.
