Basement waterproofing encompasses the full range of solutions designed to prevent water from entering your home’s basement or below-grade spaces — and to manage any water that does enter before it causes structural damage, mold growth, or indoor air quality problems. One Speed Services provides interior and exterior basement waterproofing solutions including interior drainage systems, sump pump installation and service, vapor barriers, wall crack repair, and floor-to-wall joint sealing.
A wet basement is never just a storage problem. The U.S. EPA documents that moisture in below-grade spaces is one of the primary drivers of mold growth in residential buildings, and that mold-contaminated air from basements infiltrates living spaces through the same stack effect that draws all below-grade air upward through a home. For Canby homeowners, a dry and protected basement is a foundational component of healthy indoor air quality throughout the entire house.
Canby is situated in the Willamette Valley lowlands near the confluence of the Molalla and Willamette Rivers. This geographic position — in the floodplain and river terrace soils of one of Oregon’s major river systems — creates a soil and groundwater environment that is fundamentally more challenging for below-grade residential spaces than higher-elevation surrounding communities.
The FEMA Flood Map Service Center identifies portions of Canby within Special Flood Hazard Areas associated with the Molalla River and its tributaries. Even properties outside formal flood zones experience elevated groundwater tables during Oregon’s wet season that put direct hydrostatic pressure on basement walls and floors — the primary driver of basement water intrusion that is not caused by surface drainage failure.
The NOAA National Weather Service Portland office documents that the Willamette Valley receives the majority of its annual precipitation between October and May. Canby’s lowland position amplifies the impact of this extended rainy season: saturated soils, elevated groundwater, and surface water pooling near foundations during extended precipitation events create sustained hydrostatic pressure on basement walls and floors that older waterproofing systems were not designed to manage indefinitely.
The Oregon Water Resources Department documents the Willamette Basin’s hydrological characteristics, including the groundwater response to seasonal precipitation that affects communities throughout the valley floor. For Canby homeowners, high groundwater during wet winters is a predictable annual challenge that requires a properly engineered waterproofing system — not periodic emergency response.
Canby’s older homes were built at a time when basement waterproofing standards were significantly less rigorous than today’s construction practices. Original perimeter drains — where they exist at all — are frequently clogged with silt and organic material after decades of service. Parging and original waterproofing coatings on foundation walls crack and fail over time, particularly in the freeze-thaw cycling and sustained soil moisture typical of Oregon winters.
Foundation wall cracks — even hairline cracks — allow water to enter under hydrostatic pressure during wet seasons. Left unaddressed, these entry points allow not just water infiltration but soil gas infiltration, including radon and moisture-laden sub-surface air that drives mold growth and indoor air quality problems in the living spaces above.
Visible water on the basement floor during or after significant rain events, particularly concentrated along walls or at the floor-wall joint.
Efflorescence on basement walls — the white mineral deposits left behind when water passes through masonry walls and evaporates on the interior surface. Efflorescence is a reliable indicator of sustained water movement through your basement walls.
Musty odor in the basement that intensifies after rain events or during Oregon’s wet season. A musty basement smell indicates active mold growth driven by moisture that has found entry points into the space.
Visible mold growth on walls, floors, or stored items. Any visible mold in a basement indicates moisture conditions that require waterproofing intervention, not just mold treatment.
Wall cracks, particularly horizontal or stair-step cracks. Horizontal cracks in foundation walls indicate significant lateral soil pressure and warrant immediate professional evaluation.
High indoor humidity throughout the home during wet months. Moisture that enters through a basement or crawl space is drawn upward through the home by the stack effect, elevating indoor humidity and driving mold risk throughout the living space.

One Speed Services — Canby’s Indoor Home Health Team. Family-Owned. BBB Accredited. Canby Chamber Member.
Canby’s lowland position near the Molalla and Willamette Rivers creates elevated groundwater and flooding risk for many properties — particularly during Oregon’s extended wet season from October through May. FEMA flood maps identify portions of Canby within Special Flood Hazard Areas, but elevated groundwater affects many properties outside formal flood zones as well. A professional basement evaluation gives you a definitive assessment of your specific risk.
Hydrostatic pressure — the pressure exerted by saturated soil against your foundation walls — can force water through porous masonry, wall cracks, and the floor-wall joint even without a surface flooding event. Canby’s river terrace soils and seasonal groundwater elevation make hydrostatic pressure a common cause of basement water intrusion during wet winters.

One Speed Services was contracted to remove the old blown-in insulation from the attic of our 1954 house. Jose and Tanner of One Speed Services arrived at the scheduled time preceded with an appropriate text notification. They surveyed the attic insulation removal job, assessed the needs for equi...

I couldn’t be happier with their service. My initial call to make an appointment and ask questions was so pleasant. Sweetest woman ever! Chaz serviced my home cleaning my vents/HVAC ducts. I’ve never had it done before and was a bit anxious, but he was very kind, and professional, and...

Edwin and John cleaned the dryer vent as well. Nice team work! They were prompt, very thorough and professional. Best of all, I have peace of mind regarding the air I breathe in my house for the next while. Thank you, Annie

Great service (and company). Domanic did an awesome job cleaning our air ducts and dryer vent. He was very thorough and explained everything he was going to do. The best part was seeing the before and after photos. I highly recommend and will use them again!

David, Travis and Joe came to my new house to work on my crawlspace and repair sump pumps, wet ducts and the vapor barrier. These three have been great to work with. They were always on time, professional and took as much time as I needed to explain the complicated work that was completed under...
