The short answer
Find and Stop the Source
Your first priority is to identify where the sewage is coming from and stop the flow. This could be a blocked drain, a backed-up main line, or a broken pipe. Shut off the water to the fixture or area if possible. Knowing your main water shutoff valve location is helpful for emergencies like this.
Once the flow stops, prevent further contamination by keeping people and pets out of the affected area. Do not use any toilets, sinks, or drains connected to that line until the blockage is cleared. A plumber can help locate and repair the physical break or obstruction causing the backup.
Remove Contaminated Water and Debris
All standing sewage water must be extracted immediately. Use a wet-dry vacuum if you have one, but wear protective gear like gloves, goggles, and rubber boots. Sewage contains harmful bacteria and viruses, so direct contact is dangerous. Any items soaked in sewage, like rugs or cardboard, are likely unsalvageable and should be discarded.
Porous materials that absorbed sewage, such as drywall, insulation, and some flooring, often hold odor and contaminants permanently. These materials usually need to be cut out and removed. The goal is to expose the underlying, clean structure to allow for proper cleaning, disinfection, and drying of the remaining surfaces.
- Wear personal protective equipment (PPE) like gloves, goggles, and boots.
- Discard porous, non-essential items like cardboard boxes and stuffed toys.
- Remove saturated carpet, padding, and area rugs from the home.
- Cut out and discard drywall and insulation that got wet.
- Place all contaminated debris in heavy-duty plastic bags for disposal.
- Wash your hands and arms thoroughly after handling any contaminated items.
Clean and Disinfect All Surfaces
After removal, every hard surface must be scrubbed with a heavy-duty cleaner and hot water. This includes subfloors, concrete, wood studs, and the undersides of cabinetry. The cleaning physically removes the organic matter that causes odors. Pay special attention to crevices and corners where residue can hide.
Following cleaning, apply a disinfectant approved by the EPA for use against sewage contaminants. Bleach solutions are common, but they must be mixed correctly to be effective and safe for the surface. Always follow the product label instructions for dwell time, which is how long the disinfectant must stay wet on the surface to kill pathogens.
Address Lingering Odors in the Air
Even after cleaning, smells can linger in the air and within porous materials like wood or concrete. Open all windows and use fans to exhaust air outdoors, not into other rooms. Running dehumidifiers is critical to lower humidity, which slows bacterial growth and helps materials dry completely. This is especially important in a humid climate where drying can take longer.
For persistent odors, you may need specialized treatments. Ozone generators or hydroxyl machines can break down odor molecules, but they require the space to be vacated during treatment. Thermal fogging uses a heated deodorizing mist that penetrates materials. These are advanced techniques often handled by the pros.
When to Call Water Damage Professionals
For any significant sewage backup, contacting local water damage pros is strongly advised. They have the training, industrial equipment, and EPA-registered antimicrobial agents to safely handle biohazards. They can ensure the area is fully decontaminated, dried, and deodorized to prevent mold and protect your health.
The cost for professional sewage cleanup depends on the size of the affected area, the extent of contamination, and the materials involved. It is often a multi-step process. Policies vary, and your insurer decides what is covered. Discuss the incident with your insurance company to understand your coverage options.

Is the smell from sewage dangerous to breathe?
Yes, sewage gases contain hydrogen sulfide and methane, which can cause headaches, nausea, and dizziness. More importantly, the smell indicates the presence of harmful bacteria and viruses in the air and on surfaces. Protect yourself by leaving the area and wearing proper safety gear if you must enter.
Can I clean a small sewage spill myself?
For a very small, contained spill, you can clean it if you take proper precautions. Wear full protective gear, remove all water, and clean with a detergent followed by an EPA-registered disinfectant. However, if the spill is larger than a few square feet or has soaked into walls or floors, call the pros.
Will my homeowners insurance cover sewage cleanup?
Coverage depends on the cause of the backup. Sudden, accidental events like a tree root breaking a pipe may be covered. Damage from lack of maintenance or from water entering through ground seepage often is not. Policies vary, and your insurer decides what is covered. Review your policy and report the loss promptly.
