Is It Safe to Stay in a House With a Sewer Leak?
Last updated October 26, 2026
The short answer
Health Risks of Sewer Leaks
Sewer leaks release untreated wastewater that carries pathogens like E. Coli, hepatitis A, and norovirus. Direct contact with sewage or contaminated surfaces can cause skin infections, gastrointestinal illness, and respiratory problems. Even if you don't touch the water, airborne particles from the leak can be inhaled, especially in enclosed spaces.
Children, pregnant women, older adults, and people with chronic conditions face higher risks. If you feel unwell after exposure, see a doctor. The safest choice is to leave the affected area until a professional has assessed the situation and cleaned up properly.
Immediate Steps to Protect Your Family
If you discover a sewer leak, turn off the water supply to that fixture if you can do so safely. Keep everyone, especially pets, away from the affected area. Open windows for ventilation if it's safe, but avoid walking through standing sewage.
Do not use the toilet, sinks, or showers connected to the leak. That can spread contamination further. If the leak is near electrical outlets or appliances, shut off the power at the breaker to prevent shocks. Then call local water damage pros to evaluate the situation.
- Turn off the water valve for that fixture if accessible.
- Keep children and pets out of the room entirely.
- Open windows to ventilate, but do not touch sewage.
- Avoid flushing toilets or running water in the affected area.
- Shut off electricity if the leak is near outlets or devices.
- Wash your hands thoroughly if you come into contact with anything.
What the Pros Do for Sewer Leaks
Sewer cleanup is not a DIY job. Local water damage pros have the right equipment to remove sewage safely, including pumps, wet vacuums, and industrial-grade disinfectants. They also use moisture meters to find hidden contamination in walls and floors.
The work usually involves extracting the sewage, disinfecting all affected surfaces, and drying the area thoroughly to prevent mold. In severe cases, they may need to remove and replace drywall, flooring, or insulation. You should not re-enter the area until the cleanup is complete and the space is dry.
Preventing Future Sewer Leaks
Regular maintenance can help you avoid sewer leaks. Have a plumber inspect your sewer lines periodically, especially if you have old pipes or tree roots near your property. Watch for warning signs like slow drains, gurgling sounds, or sewage odors in your home.
If you live in Daytona Beach, keep your shutoff valve location written down. The humid subtropical climate can accelerate pipe corrosion, so staying alert to early signs is wise. Fix small clogs or cracks promptly before they turn into major leaks.
When to Call for Help
Call the pros as soon as you notice a sewer leak, even if it seems small. The longer sewage sits, the deeper it soaks into porous materials, making cleanup harder and increasing health risks. Do not wait for symptoms to appear.
The cost of sewer cleanup depends on the extent of the damage, the affected area, and the materials involved. Typically, it can range from a few hundred to several thousand dollars. Your insurance company may help, but policies vary, and your insurer decides what is covered. Check your policy to understand your options.
- Sewage odor that persists or worsens.
- Slow draining sinks, tubs, or toilets.
- Gurgling sounds from pipes.
- Wet spots or stains on walls, floors, or ceilings.
- Visible sewage backup in fixtures.
- Rodent or insect activity near drains.
