Sewer Backup Cleanup in Sherwood Park: What Homeowners Need to Know

A sewer backup is the most serious type of water damage a Sherwood Park homeowner can face. During intense summer storms, or when a private sewer line is blocked by roots, grease or a collapsed pipe, sewage can come up through the basement floor drain, toilet or shower. That’s Category 3 “black water”, carrying bacteria and viruses, and it needs professional cleanup.

Is It a Main-Line or Municipal Problem?

• Only your house affected, gurgling drains, slow toilets: likely a blockage in your private sewer line between the house and the property line. Call a plumber or drain-cleaning company.
• Several homes on your street affected during heavy rain: possibly a municipal system issue. Contact Strathcona County Utilities.

What to Do Immediately

1. Stop using water. No flushing, showers, laundry or dishwasher.
2. Keep everyone out of the contaminated area, especially children, pets and anyone with a weak immune system.
3. Turn off power to the basement from a dry location if water is near electrical.
4. Don’t run the furnace if the furnace or return air ducts are in the affected area.
5. Photograph everything and call your insurer.
6. Call a professional for water damage restoration in Sherwood Park.

How Professional Sewer Backup Cleanup Works

1. Containment

The area is sealed with plastic barriers and HEPA air scrubbers create negative air pressure so contamination doesn’t spread upstairs.

2. Extraction

Sewage and solids are pumped out and disposed of properly.

3. Removal of porous materials

Carpet, underlay, insulation, and drywall (usually a 2–4 foot flood cut) that touched sewage are bagged and removed, following the IICRC S500 standard.

4. Cleaning and disinfection

Concrete, framing and hard surfaces are scrubbed and treated with disinfectants and antimicrobials.

5. Drying and verification

Structural drying with dehumidifiers and air movers, checked with moisture meters. See drying timeline.

6. Rebuild

Insulation, drywall, paint and flooring are replaced.

Cost and Insurance

Sewer backups in finished basements commonly cost $12,000–$35,000+ with rebuild (cost guide). In Alberta, sewer backup coverage is typically an optional add-on to a home policy, and it often has its own limit and deductible. Check your policy before you need it. See our Alberta insurance guide.

Prevent the Next Backup

• Install a backwater valve on your main sewer line, by a licensed plumber with the required permit, and maintain it annually.
• Never pour fats, oils or grease down drains.
• Flush only toilet paper. Wipes clog lines even when labelled “flushable”.
• Camera-inspect your sewer line if you have mature trees or an older home in neighbourhoods like Glen Allan, Westboro or Broadmoor.
• Make sure your sump pump and downspouts don’t discharge into the sanitary sewer.
• Store valuables in plastic bins, off the basement floor.
