A sewage backup is one of those emergencies nobody plans for. One minute your basement drain is gurgling; the next, contaminated water is spreading across the floor. In our years serving Metro Atlanta, we’ve seen well-meaning homeowners make a bad situation worse in the first hour — usually by touching things they shouldn’t. Here’s exactly what to do (and what to avoid) when sewage backs up in your home.
First: Understand What You’re Dealing With
Sewage is what the restoration industry calls Category 3 water — “black water.” It carries bacteria like E. coli and salmonella, viruses, and parasites. That’s why the rules for a sewage backup are different from a clean-water leak from a supply line. With sewage, exposure itself is the hazard, not just the moisture.
Do These 5 Things Immediately
- Keep people and pets out. Close off the affected room. Kids and animals are drawn to standing water — don’t give them the chance.
- Stop using water in the house. If the main sewer line is blocked, every flush, shower, and laundry cycle sends more sewage into your home.
- Turn off electricity to the affected area — but only if you can reach your panel without stepping in water.
- Call your insurance company. Ask specifically whether your policy includes a water/sewer backup endorsement. Many Georgia policies only cover sewage backups if this rider was added.
- Call a certified restoration company. Sewage cleanup is not a shop-vac job. TerraPro Group’s sewage cleanup crews respond 24/7 across Metro Atlanta: (470) 791-0204.
Don’t Touch These Things
- The water itself. Even brief skin contact can transmit pathogens. If you must enter, wear rubber boots and gloves — and wash thoroughly after.
- Wet carpet and rugs. Dragging saturated carpet through the house spreads contamination to clean areas. Carpet exposed to sewage almost always has to be replaced anyway.
- Your HVAC system. Don’t run fans or your air conditioner to “dry things out” — you’ll circulate contaminated aerosols through the whole house.
- Household cleaners. A bottle of bleach doesn’t disinfect porous materials, and mixing cleaners over sewage can create dangerous fumes.
- Food, toys, and soft goods that contacted the water. When in doubt, photograph it for the claim and set it aside for the pros to evaluate.
Why Sewage Backups Happen in Metro Atlanta
Atlanta’s established neighborhoods — Sandy Springs, Dunwoody, Roswell, Brookhaven — have mature trees and, in many cases, decades-old clay sewer laterals. Roots find joints in those pipes and slowly choke the line. Add one of our signature summer downpours overwhelming municipal systems, and backups spike. If your home has a basement, a failed ejector pump or backwater valve is another common culprit — something we covered in our guide to basement and crawl space flooding.
What Professional Cleanup Looks Like
A certified crew will contain the area, extract the sewage safely, remove contaminated porous materials (carpet, pad, affected drywall), disinfect with hospital-grade antimicrobials, and dry the structure to verified moisture standards. Done right, this prevents the two long-tail problems that follow bad cleanups: lingering odor and mold growth inside walls.
Protect Your Home Before It Happens Again
Once the cleanup is done, ask about prevention: a backwater valve on the main line, root treatment or pipe repair for older laterals, and a battery backup for your sump or ejector pump. And check your insurance policy today — the water/sewer backup endorsement usually costs little but makes all the difference when you need it.
