Stillwater homes sit on bluff lots with stone and rubble foundations that meet river-influenced groundwater, especially along the St. Croix. Crews work around historic streets and steep driveways when responding from the Osseo location.
Seasonal patterns follow the humid continental climate, with spring melt and summer rains driving most calls in Washington County river towns like Stillwater.
Everything that follows applies right here in Stillwater (55082): the offerings, the process, and the pricing approach we use statewide.
In older Minneapolis and Saint Paul neighborhoods, combined sewers surcharge during heavy spring rains or rapid snowmelt, pushing sewage upward through floor drains rather than allowing it to drain away. Finished basements with carpet, drywall, and cabinetry absorb this water immediately, and the porous materials hold contamination deep into the subfloor and wall cavities. Extraction must begin with full PPE and containment barriers because the water is Category 3 from the first moment it enters the space.
Technicians remove all saturated porous materials on contact, including carpet, pad, base trim, and lower sections of drywall, because these items cannot be salvaged once sewage has wicked into them. Non-porous surfaces such as concrete floors and sealed cabinets receive repeated antimicrobial applications followed by verification with moisture meters. Air movers and dehumidifiers run continuously afterward, but winter conditions limit ventilation options so drying times extend and negative air machines stay in place longer to control odors.
How It Works in Stillwater
- 1
Site Assessment and Containment
Technicians arrive, establish containment zones, and document the extent of sewage migration through finished basement materials.
- 2
Extraction of Contaminated Water
Standing sewage is removed using truck-mounted extraction units while waste is contained for licensed disposal.
- 3
Removal of Affected Materials
All porous items that contacted Category 3 water are cut out and bagged for proper transport and disposal.
- 4
Disinfection and Drying
Hard surfaces receive antimicrobial treatment, then drying equipment runs until moisture readings return to normal.
