When sewage backs up under the house, it pools in the crawl space where you can't see it — soaking into insulation, sitting on the vapor barrier, and giving off odor that works its way up into the home. Affordable Sewage Backup Cleanup removes the sewage from the crawl space, takes out contaminated insulation and debris, and sanitizes the area. The plumbing that caused the backup is a separate, plumber's job.
Crawl space sewage cleanup Marietta GA is the process of removing raw sewage, contaminated standing water, and soaked insulation or vapor barrier from the space under your home, then disinfecting and drying it to IICRC standards. It is not a shop-vac job. We pump out the standing water with a truck-mounted extraction unit, bag and haul off saturated debris, treat every surface with antimicrobial disinfectant, and run dehumidifiers and air scrubbers until a moisture meter reads dry. Left alone, that water wicks into floor joists and subfloor within days.
Most calls we get start the same way: a toilet backs up, a sewer line clogs, or a septic backup pushes waste into the lowest point of the house. In Marietta that lowest point is almost always the crawl space. Homes near Fair Oaks and Westoak sit on clay-heavy soil that shifts with our wet winters and dry summers, and that movement cracks older PVC sewer pipe. Tree roots from mature pines and oaks do the rest. If you are searching for crawl space sewage cleanup in Marietta GA near me at., we answer.
Every job is scoped to the actual contamination, but these are the core items we handle on a standard crawl space sewage backup cleanup in Marietta GA. If your situation needs something beyond this list, like full vapor barrier replacement or duct cleaning, we will tell you upfront and price it separately.
Truck-mounted extraction units and submersible pumps pull standing sewage and contaminated water out of the crawl space. We work around piers, ductwork, and plumbing runs so nothing gets missed and the space is dry enough to walk safely.
Soaked insulation, ruined vapor barrier, cardboard, and any porous material that touched sewage gets bagged and hauled off. These items cannot be dried and reused, and leaving them behind is how mold growth after water damage starts.
We apply antimicrobial disinfectant and biocide to joists, subfloor, piers, and the soil surface. This step kills bacteria and viruses left behind by the sewage and is what actually eliminates the sewer gas smell at the source.
Dri-Eaz and Phoenix dehumidifiers plus HEPA air scrubbers run for two to four days depending on how saturated the framing is. We monitor with moisture meters and thermal cameras and adjust until readings are back to normal.
After the biocide dries, we treat the space with odor neutralizer to eliminate any lingering smell. This is different from masking it with fragrance, and it is the step most fly-by-night crews skip.
Photo log, moisture readings, scope of work, and equipment logs, all packaged for your adjuster. If your policy has a sewage backup endorsement, this documentation is what gets the claim approved without back-and-forth.
You call, we ask a few questions about where the water is and how long it has been there, and we dispatch. On arrival we suit up in PPE, check for sewer gas, and walk the crawl space with a flashlight and moisture meter to map the contamination. This takes 15 to 30 minutes.
Extraction is pointless if the line is still backing up. We run a sewer camera inspection system to find the clog or break, then clear it with a drain snake or hydro-jetter. If the problem is root intrusion or a collapsed pipe, we tell you what needs a plumber before we go further.
A truck-mounted extraction unit and submersible sewage pump pull the standing water out fast. Anything porous that soaked up sewage, like insulation batts, cardboard, or old vapor barrier, gets bagged and hauled off. We lay plastic sheeting to protect the access path through your house.
We spray or fog every surface with antimicrobial disinfectant, then set Dri-Eaz and Phoenix dehumidifiers plus HEPA air scrubbers. Depending on how wet the wood is, drying runs two to four days. We check readings daily and adjust equipment until the space is dry.
Final walk-through with a moisture meter and thermal camera to confirm every reading is back to normal. We pull our equipment, give you the photo log and drying report, and explain what to watch for. If a backwater valve makes sense for your line, we will say so.

Pulls large volumes of sewage and contaminated water out of the crawl space fast, far more than a wet/dry shop vac could handle. This is the first piece of equipment on site.
Used when standing water is too deep or too far from the access point for the extraction hose. Pumps the water out to a safe discharge point.
Lets us see inside the line to find the clog, root intrusion, or break before and after extraction. We use Spartan Tool and General Pipe Cleaners equipment.
Clears grease, roots, and scale from the sewer line when a drain snake is not enough. Restores full flow so the backup does not repeat.
Filters airborne bacteria, mold spores, and sewage particles out of the crawl space air during and after remediation. Critical for indoor air quality.
Pull moisture out of framing, subfloor, and soil over two to four days. We monitor with moisture meters and thermal cameras to confirm drying targets.
A 1978 ranch had sewage backing up into the crawl space for two days before the homeowner called. Standing waste covered about 300 square feet of vapor barrier, and insulation batts were saturated. The smell was strong throughout the house.
After: We extracted 180 gallons of contaminated water, removed 14 insulation batts and 300 square feet of vapor barrier, and sanitized the entire cavity. Drying ran three days. Final moisture readings were back to baseline across all 22 checkpoints.

A second-floor toilet overflowed overnight and water ran down through the subfloor into the crawl space. About 120 square feet of the crawl space was contaminated, and the bathroom floor above was saturated.
After: We extracted from both levels, removed soaked insulation, and sanitized the crawl space and bathroom. Drying equipment ran 48 hours. Moisture readings on the bathroom subfloor and crawl space framing both returned to normal.

A home on septic had a drain field failure that pushed waste back into the lowest drain, which drained into the crawl space. About 200 square feet was affected, and the homeowner had been dealing with the smell for a week.
After: We pumped out the standing water, removed contaminated material, and sanitized the space. We coordinated septic pumping and a drain field assessment. Drying ran four days because the soil was saturated. The smell was gone at final walk-through.
Book this service →Sewage under the house shows up in different ways depending on the source and how long it has been sitting. These are the calls we run most often for crawl space sewage cleanup and odor control Marietta GA homeowners need.
Ask a pro →We camera the line to locate the clog, clear it with a drain snake or hydro-jetter, then extract and sanitize the crawl space. If the pipe is cracked or root-invaded, we document it so your plumber can make the repair.
We pump out the standing water with a submersible sewage pump, stop the inflow by coordinating septic service, then dry and disinfect the entire cavity to IICRC standards.
We use thermal imaging and a moisture meter to find every wet pocket, remove contaminated material, apply biocide, and finish with odor neutralizer. The smell is gone because the source is gone.
We treat with antimicrobial disinfectant, HEPA-scrub the air, and dry the framing to target moisture content. For heavy growth we follow IICRC AMRT protocols and document everything for your records.
Most residential jobs run $1,800 to $6,500 in 2026, with the average around $3,200. Small, contained backups where we extract and sanitize a limited area land near the low end. Full tear-outs with soaked insulation, damaged vapor barrier, and several days of drying push higher. Square footage, contamination depth, and whether the source line needs repair are the three biggest cost drivers.

The four most common causes we find are tree root intrusion into older clay or cast-iron laterals, grease buildup in the line, a collapsed or offset pipe from soil movement, and septic system failure on properties outside city sewer. Marietta's mature tree canopy and clay-heavy soil make root intrusion the number one culprit, especially on homes built before 1990.
Most standard homeowner policies cover sudden and accidental sewage backup, often under a specific backup endorsement, and that usually includes extraction, sanitizing, and drying.
