Main Line Backups
When the main clogs, waste comes up the lowest fixture, usually a basement floor drain or shower. Standing waste is pumped and extracted before any material removal starts.
- Extraction of standing waste
- Cleanout access checked
Raw sewage backing into your home carries bacteria and viruses that a mop and bleach will not handle. Call Water Heater Repairer and a live dispatcher will route you to an independent, licensed and insured cleanup contractor who works in full protective gear.

Under IICRC S500 guidance, sewage is Category 3 water, which means it is treated as grossly contaminated from the start. It needs a disciplined sequence and proper protection, otherwise the cleanup spreads the problem rather than ending it.
Calls are routed to licensed and insured independent contractors who suit up in respirators, Tyvek coveralls, nitrile gloves, and rubber boots. Plenty hold IICRC training, and you are welcome to ask for proof on arrival.
Because waste wicks into porous materials quickly, an active backup goes to the front of the queue. Response is usually fast, though a citywide surcharge can stack calls up for everyone.
You get a written, flat-rate scope listing every material to be removed before any tear-out begins. That paper also helps when you file with your insurer.
Expect EPA-registered disinfectants, HEPA vacuums, and air scrubbers built for contaminated jobs. If you want proof the area is clean, ask about ATP or swab testing at the end.
Most backups we hear about start with a clog in the main sewer line, often roots, grease, or a collapsed section of old clay pipe. Others come from the city side, when heavy rain overloads the municipal sewer and it surcharges back into basements. Either way, the cleanup is the same, but the fix to stop it happening again is not.
So we can line up a licensed plumber to run a camera through the line while the cleanup contractor works. Knowing what failed keeps you from paying for the same cleanup twice.

Every sewage job follows the same rule: contain, remove, clean, disinfect, then dry.
When the main clogs, waste comes up the lowest fixture, usually a basement floor drain or shower. Standing waste is pumped and extracted before any material removal starts.
A toilet that kept running over can saturate the subfloor and stain the ceiling underneath. The contractor checks the underlayment and ceiling cavity with a moisture meter before deciding what to remove.
Carpet and pad that sewage reached cannot be cleaned and go straight into contractor bags. Drywall gets cut well above the high-water line, and wet insulation behind it comes out too.
Hard surfaces are HEPA vacuumed, scrubbed, and treated with an EPA-registered disinfectant with proper dwell time. Negative air machines keep contaminated air from reaching the rest of the home.
A licensed plumber can run a camera through the cleanout to find roots, bellies, or collapsed pipe. If the city line surcharges, a backwater prevention valve can block it from coming into the home.
After removal and disinfection, the framing and slab need to be fully dry before anything new goes in. Expect air movers, dehumidifiers, and daily moisture logs, with HEPA air scrubbers handling the smell.
Four steps, handled by people who do this work every week.
We tell you to stop all water use, keep kids and pets away from the area, and shut off power if water is near outlets. Then we ask where it came up and whether neighbors on a shared line have the same problem.
An independent cleanup contractor near you heads over with PPE, extraction gear, and containment supplies. If the drain is still clogged, a licensed plumber can be lined up to open it.
The pro traces the contamination, checks moisture in walls and floors, and decides what must be removed. You get a written flat-rate quote and photos before tear-out begins.
Once materials are out and surfaces are disinfected and dry, you get a walkthrough and the moisture logs. Ask whether swab testing is available and whether their work carries a written warranty.
A bleach wipe-down may look clean, yet the waste trapped in drywall paper and carpet pad keeps breeding bacteria. A regular shop vac can aerosolize the contamination and spread it through the room. That lingering smell a week later is usually the sign something porous got left behind.

Stop all water use, keep everyone out of the area, and call.
After a big storm, the basement floor drain started bubbling and then just kept coming. The contractor showed up in full suits and respirators, pulled the carpet and the bottom two feet of drywall, and ran air scrubbers the whole time. They recommended a backwater valve, and a plumber installed one a week later.
With a small kid and a dog in the house, I was mostly worried about germs. They put up plastic containment, disinfected every surface, and did swab tests so I knew it was clean. Having actual results made it easy to let my son back in there.
The other half of our duplex shares the lateral, and their clog came up through my shower. The plumber ran a camera and found roots in the old clay pipe right at the property line. The cleanup contractor and the plumber both put everything in writing, which helped sort out who paid for what.
The smell hit me the second I opened the basement door, and I honestly did not know who to call first. The dispatcher told me to stop running water, sent a plumber to clear the main, and had a cleanup contractor there that afternoon. My adjuster took the itemized scope and photos as-is, which saved a lot of back and forth.
If the spill is limited to one room, staying elsewhere in the home is usually fine once containment goes up. Anyone vulnerable, including kids, seniors, and people with health issues, should keep clear until the area is disinfected.
Not safely, since IICRC guidance treats carpet and pad hit by sewage as material that must be discarded. Hard items like tile, concrete, and sealed wood can usually be cleaned and disinfected instead.
Most often the main sewer line is blocked by roots, grease, or a cracked section. After heavy rain, it can also be the municipal sewer surcharging back up the lateral, which a camera inspection can help sort out.
It is a one-way flap that shuts when the city line surcharges, blocking flow back into the home. It will not fix a clog on your own line, so a camera inspection still matters.
Many standard policies exclude sewer backup unless you added a specific water backup endorsement. Check with your insurer, document everything with photos, and hold onto the written quote and moisture records.
Ask the contractor about clearance testing, such as ATP readings or surface swabs sent to a lab. You should also get moisture readings showing framing and subfloor are dry before anything is rebuilt.
We route calls to independent cleanup contractors working throughout Memphis and the surrounding suburbs. Coverage reaches zip codes like 48041.
Older neighborhoods in Memphis tend to have clay or cast iron sewer laterals, prime spots for roots and breaks. Homes on lower ground get hit harder when storm water overloads the city system. Tell the dispatcher your home's age and whether it has backed up before, and we route accordingly.
