Severn and Odenton basements often sit on clay-heavy Anne Arundel soils that hold water after summer storms. When sewage backs up, the first step is isolating the affected slab or crawl space so contaminated water does not migrate into finished areas or HVAC returns. Technicians use submersible pumps rated for solids and extract until standing liquid is gone, then remove saturated drywall and insulation up to the flood line to prevent hidden mold growth common in the region’s humid subtropical summers.
Mild winters in Glen Burnie and Annapolis keep groundwater tables higher than in colder climates, so backups frequently recur within days if the main line or septic tie-in is not addressed. Crews pressure-wash concrete with EPA-registered disinfectants, then apply antimicrobial sealers on porous block walls before drying equipment runs. Homeowners in older Severn neighborhoods near Telegraph Road should expect permits for any waste-water disposal that leaves the property.
Edge cases include finished basements with carpet glued directly to slab; the adhesive traps bacteria and must be cut out in sections. After extraction, moisture meters check joists and subfloor because residual humidity above 60 percent allows rapid bacterial regrowth. Final clearance includes a written report noting any Anne Arundel County health-department notification requirements for large-volume discharges.
Technician insight
In Severn homes along Telegraph Road the clay soils of Anne Arundel County hold water long after rain stops, so many basements re-flood within 48 hours if the cleanout is not located and cleared before we leave the site.
Sewage Backup After Summer Storm in Odenton
Heavy rain overwhelmed the main line serving an older slab home in Odenton. Standing sewage reached the baseboard heaters. We extracted the liquid, removed two sections of affected drywall, disinfected the slab, and ran drying equipment for three days until moisture readings cleared.
Basement Sewage Cleanup Services We Offer
✓Raw Sewage Extraction
Pump and remove standing sewage from Severn and Odenton basements using solids-handling equipment sized for residential slab depths.
✓Contaminated Material Removal
Cut out and bag saturated carpet, drywall, and insulation up to the contamination line so hidden bacteria do not remain in Anne Arundel County homes.
✓Basement Disinfection
Apply EPA-registered disinfectants to concrete and block walls followed by antimicrobial rinse to meet local health standards after sewage events.
✓Odor Elimination Treatment
Fog and seal porous surfaces with odor-neutralizing agents that address the hydrogen-sulfide smell common after backups in humid Severn summers.
✓Moisture Mapping and Drying
Use thermal imaging and moisture meters on joists and slabs, then run commercial dehumidifiers until readings drop below regional mold thresholds.

How it works
- 1
Site Assessment
Technician inspects the basement, traces the backup source, and notes any nearby utilities or finished areas that could be affected.
- 2
Extraction
Pump out standing sewage and remove bulk contaminated solids to prevent further migration into Odenton or Severn crawl spaces.
- 3
Cleaning And Disinfection
Pressure wash surfaces, apply disinfectants, and remove porous materials that cannot be restored.
- 4
Drying And Clearance
Run drying equipment, verify moisture levels, and provide documentation for homeowners in Anne Arundel County.
Pricing
Most basement sewage jobs in Severn are priced by volume and materials removed; final cost depends on access, depth of contamination, and whether finished surfaces must be demoed.
