Sewage Backup? Do Not Touch It. Here Is What to Do.

Sewage is contaminated with bacteria and viruses, so your safety comes before your property. The right move is to stay away from it and let a trained crew handle it. Here is what to do and, just as important, what not to do.

Do this

  • Keep everyone away from the area, especially children and pets.
  • Turn off power to the affected area at the breaker, only if you can reach it without stepping in the water.
  • Stop using water in the house. Do not flush toilets or run sinks, which can add to the backup.
  • Open a window near the area if you can do it without walking through the sewage.
  • Take photos from a safe distance for your insurance claim.
  • Call us right away.

Do not do this

  • Do not touch the sewage or any surface it has reached.
  • Do not try to clean it up yourself, and do not use a shop vac.
  • Do not run your HVAC, air conditioning, or fans. Moving the air spreads the contamination through your ducts and into rooms nobody entered.
  • Do not just pour bleach on it and hope it is enough. Sewage soaks into materials where surface bleach cannot reach.
Why cleaning it yourself makes it worse: Mopping and running fans does not remove sewage, it turns it into a fine mist. Those airborne droplets carry the bacteria and viruses into your air, your vents, and rooms far from the backup. What starts as one contaminated room can become a whole-home problem. This is why sewage is a job for trained crews with proper equipment.

Warning Signs You Have a Sewer Backup, Not Just a Clog

One slow drain is usually just a clog. A sewer backup shows itself in more than one place at once, because the blockage is deeper in the line. Watch for these signs.

  • More than one drain backing up. If your toilet, tub, and sink all act up together, the problem is in the main line, not one fixture.
  • Gurgling toilets. Air trapped by a blockage makes toilets bubble or gurgle, especially when you run a sink or washer.
  • A sewer smell from drains. A foul, rotten smell coming up from drains or a floor drain is a warning sign of a backing-up line.
  • Slow drains throughout the house. When every drain is slow at the same time, the blockage is shared, meaning the main line.
  • A lush green patch in the yard. A cracked sewer line leaks nutrients into the soil, so one patch of lawn grows greener and faster than the rest.
If you notice these signs, stop running water in the house and call us before a small problem becomes a full backup.

Biohazard Category 3

Why Sewage Backup Is a Serious Health Hazard

Sewage is classified as Category 3 black water, the most dangerous type of water damage. It carries human waste, and with it a mix of bacteria, viruses, and parasites that can cause serious illness. This is why sewage cleanup is treated as a biohazard job, not an ordinary water cleanup.

Bacteria and Viruses

The CDC warns that sewage can carry pathogens like E. coli, Salmonella, Hepatitis A, and norovirus, which cause stomach illness, infections, and worse.

Toxic Gases

Sewage releases gases such as hydrogen sulfide and methane, which are harmful to breathe in an enclosed space.

Airborne Contamination

Disturbing sewage sends tiny droplets into the air that carry the same pathogens into your lungs and onto surfaces throughout your home.

Fast Mold Growth

The EPA says mold can start within 24 to 48 hours, and the moisture and nutrients in sewage speed that up.

Even a small backup is dangerous, and any clean water that touches sewage becomes contaminated black water too. This is why the whole affected area has to be treated, not just the visible mess.
What Causes It

What Causes Sewage Backups in Marietta Homes

A sewage backup happens when wastewater cannot flow out through the sewer line, so it comes back up through the lowest drains in your home. After more than ten years working in Cobb County, these are the causes we see most.

Tree Roots in Aging Sewer Lines

Tree roots are drawn to the water inside sewer pipes and grow in through small cracks, then expand until they block the line. Marietta's mature oaks, maples, and magnolias, combined with old clay pipes near Indian Hills and the Marietta Square, make this the top cause.

Clogs From Grease and Wipes

Grease hardens in the line, and "flushable" wipes, paper towels, and hygiene products do not break down. Over time they build up and block the main line, sending sewage back through several drains at once.

Aging Clay and Cast Iron Pipes

Many pre-1990 Marietta homes still have clay or cast iron sewer pipes. These materials corrode, crack, and collapse over decades, which blocks flow and lets sewage back up.

Clay Soil Shifting the Pipes

Marietta's red clay expands when wet and shrinks when dry. Over years, that movement cracks and misaligns underground sewer lines, the same soil behavior that causes basement flooding and foundation problems.

Municipal Sewer Overflow in Heavy Rain

During heavy storms, the public sewer system can reach capacity and push wastewater back into homes through floor drains. Cobb County publicly reports sanitary sewer overflows into Noonday Creek and Blackjack Creek, showing how often this happens during Marietta's heavy rains.

Sump Pump or Septic Failure

A sump pump failure during a storm lets water and sewage rise with nowhere to go. In homes on septic, a tank overdue for pumping or overwhelmed by rain can back up into the house.

Who Is Responsible?

Is a Sewer Backup Your Responsibility or the City's?

This is the question most homeowners do not know the answer to, and it decides who pays. The answer comes down to where the blockage is.

Your lateral (your responsibility)

You own the sewer pipe that runs from your house to the main line under the street, called the lateral. If the blockage is in that pipe, from tree roots, a clog, or a cracked line, it is your responsibility to clean up and repair.

The city main (the county's responsibility)

Cobb County owns the main line under the street. If the backup came from a blockage or overflow in that main, the county may be responsible and you may be able to file a claim for damages.

If you think the county sewer main caused the backup, report it to Cobb County right away and keep records. But do not wait on cleanup. Sewage is a health hazard that has to be removed quickly, no matter who ends up responsible for the cost.
Insurance

Does Insurance Cover Sewage Backup in Marietta?

Here is the honest answer, and it catches many homeowners off guard. A standard homeowner policy usually does not cover sewage or sewer backup on its own. Coverage normally requires a separate add-on, often called a water backup or sewer backup endorsement, that you have to buy ahead of time. It typically costs $40 to $100 a year. If you added it before the backup, you likely have coverage. If you did not, you may not.

This is different from a burst pipe, which is usually covered, and different from a flood, which needs flood insurance. Sewage backup sits in its own category.

  • We document the source, the contamination, and the damage from our first visit.
  • We tell you honestly what to check on your policy, including whether you have a backup endorsement.
  • We work with your carrier and adjuster if you have coverage.

How We Work

How We Clean Up a Sewage Backup Safely

Sewage cleanup follows strict biohazard steps to protect your family and prevent the contamination from spreading. Here is how we work. For the full detail, see our restoration process.

Containment and safety setup.

We seal off the area, put on protective gear, and check for gas and electrical hazards before we start.

Sewage and waste extraction.

We remove the standing sewage and solid waste with commercial equipment made for the job.

Removal of contaminated materials.

Porous materials the sewage touched are removed and disposed of safely, following proper handling rules.

Cleaning and HEPA vacuuming.

We clean every hard surface and HEPA vacuum to capture fine contamination.

Disinfection.

We treat all affected surfaces with EPA-approved antimicrobial products to kill bacteria and viruses.

Drying and clearance.

We dry the structure fully, then confirm the area is clean and safe before any repairs.

What Stays, What Goes

What Has to Be Removed After a Sewage Backup

With sewage, the deciding factor is whether something can be fully cleaned and disinfected. Porous materials soak up the contamination, and the smell, in a way that cannot be safely reversed.

Usually has to be removed

  • Carpet and carpet padding that contacted sewage
  • Drywall and insulation below the contamination line
  • Upholstered furniture and mattresses
  • Particleboard and pressed-wood furniture
  • Food, dishes, and containers that cannot be sanitized

Usually can be saved

  • Tile, sealed concrete, glass, and metal — after disinfection
  • Solid wood furniture, if treated quickly
Will the smell ever go away? Yes, but only after the contaminated porous materials are removed and the area is properly disinfected. Surface cleaning alone leaves the smell and the bacteria behind. We document every item we remove for your insurance claim.
What It Costs

How Much Does Sewage Backup Cleanup Cost in Marietta?

Sewage backup cleanup in Marietta usually costs $2,000 to $10,000 for most homes, and more for severe or widespread contamination. It costs more than a clean-water job because of the biohazard protocols, safe disposal, disinfection, and material removal involved. The final price depends on how much sewage there was, how far it spread, and how much material has to be replaced.

How Far It Spread

A contained bathroom backup costs far less than sewage across a finished basement.

Material Removal

Carpet, drywall, and insulation that contacted sewage must be removed and replaced.

Contamination Level

More sewage means more disinfection, disposal, and drying time, which affects the total.

Common Questions

Sewage Backup Cleanup FAQs

Yes. Sewage is Category 3 black water, the most contaminated type. The CDC warns it can carry bacteria and viruses like E. coli, Salmonella, and Hepatitis A, plus toxic gases. Even a small backup can make your family sick, and it can grow mold within a day. Keep everyone away and call professionals.
It is not safe. Sewage carries pathogens that ordinary cleaning cannot remove, and mopping or running fans turns it into an airborne mist that spreads through your home. Porous materials it soaks into cannot be disinfected. Professional cleanup uses containment, protective gear, and disinfection to make your home safe.
It depends on where the blockage is. You own the lateral, the pipe from your house to the street, so blockages there are your responsibility. Cobb County owns the main line, so if the backup came from the main, the county may be liable and you may be able to file a claim.
Usually not without an add-on. Standard homeowner policies typically exclude sewage backup unless you bought a water backup or sewer backup endorsement ahead of time, often $40 to $100 a year. This differs from a burst pipe, which is usually covered. We document everything to support your claim if you have coverage.
A single slow drain is usually a clog. A sewer backup shows up in more than one place at once, like several drains backing up, gurgling toilets, a sewer smell from drains, or slow drains throughout the house. A greener patch in the lawn can signal a cracked line outside.
Yes, but only after the contaminated porous materials are removed and the area is fully disinfected. The smell soaks into carpet, drywall, and insulation, so surface cleaning alone leaves it behind. Proper removal, disinfection, and drying take the smell out for good, which is why professional cleanup matters.
Porous materials that contacted sewage usually cannot be saved, including carpet and padding, drywall and insulation below the contamination line, mattresses, upholstered furniture, and food or dishes that cannot be sanitized. Hard surfaces like tile, sealed concrete, and metal can often be cleaned and disinfected. We document every item removed.
For a small, contained backup handled quickly, extraction and disinfection often take one to three days. Larger jobs with material removal and structural drying take longer. If sewage sits for days and mold sets in, cleanup can stretch to weeks, which is why calling right away keeps it shorter.
Yes, quickly. The EPA says mold can start within 24 to 48 hours, and the moisture and nutrients in sewage speed it up. Any porous material left wet becomes a mold risk. Fast removal, disinfection, and drying prevent it, and we treat all affected surfaces with antimicrobial products as a safeguard.
Keep everyone away, stop using water in the house, and turn off power to the area only if you can reach the breaker safely. Do not touch the sewage, run fans, or use your HVAC, since that spreads it. Take photos from a distance for insurance, then call a professional crew right away.
