A sewage backup is one of the most stressful problems a property owner can face. Wastewater can carry bacteria and other contaminants, and it can soak into flooring, drywall, and subfloors quickly. Knowing the first safe steps helps protect the people in the home and limits how far the damage spreads.
COIT Cleaning and Restoration provides 24/7 sewage cleanup in Sparks, Reno, and surrounding Northern Nevada communities, with IICRC-certified technicians serving the area since 2005.
Common Causes of Sewage Backups
Backups often come from clogged main lines, tree roots in older pipes, grease buildup, failed sump or ejector pumps, or heavy storms overwhelming municipal lines. Floor drains, basement toilets, and lower-level showers are usually where wastewater shows up first.
First Steps: Stay Safe
- Keep children and pets away from the affected area.
- Stop using sinks, toilets, showers, and appliances that drain into the line.
- If water is near outlets or appliances, shut off power only if it is safe to reach the panel.
- Avoid direct contact with wastewater and contaminated items.
- Take photos of the damage for your records and insurance.
- Call a professional sewage cleanup team as soon as possible.
What Not to Do
Don't use a household vacuum or fans to dry the area — they can spread contaminants through the home. Avoid mixing cleaning chemicals, and don't try to save porous items like carpet pad or upholstery that were soaked by sewage without professional guidance.
How Professional Sewage Cleanup Works
A professional cleanup typically includes protective containment, wastewater extraction, removal of affected porous materials, cleaning and antimicrobial treatment of hard surfaces, structural drying, and moisture verification. COIT's sewage cleanup service in Sparks and Reno documents each step with photos and moisture readings.
Because wastewater soaks into building materials, the drying stage matters just as much as cleaning. Learn more about extraction and drying on the water damage restoration page, or read what to do after water damage.
Why Speed Matters
Materials that stay wet for more than a day or two can support mold growth. If moisture lingers after a backup, a mold inspection can confirm whether further work is needed. See also why mold clearance testing matters.
Insurance and Documentation
Coverage for sewage backups depends on your policy and the cause of loss — some policies require a separate backup endorsement. Photos, moisture logs, and a written scope of work help support any claim you file.
