About Sewage Backup Cleanup in Myrtle Beach
Sewage backup is a Category 3 biohazard emergency requiring immediate professional response. Services include sewage extraction with industrial equipment, full decontamination with EPA-registered disinfectants, HEPA air scrubbing, material removal, and documentation for insurance claims.
Myrtle Beach context: Myrtle Beach area water damage risk includes South Carolina's Atlantic hurricane exposure and intense subtropical rainfall. The Lowcountry and coastal plain face dual threats from storm surge and hurricane rainfall flooding. Midlands communities face river flooding from tributaries of the Congaree, Wateree, and Pee Dee Rivers. Upstate SC (Greenville, Spartanburg) receives 50+ inches of annual rainfall with thunderstorm-driven flash floods in summer. South Carolina's clay-rich soils create hydrostatic pressure challenges for basement and crawl space construction.

Quick answer
Sewage backup cleanup handles Category 3 water, which carries pathogens and cannot simply be dried. Porous materials the sewage touched — carpet, pad, drywall, insulation — are removed rather than salvaged, and surfaces are disinfected under containment with HEPA filtration. Typical cost is $2,000–$10,000 over about five days. This is not safe DIY work beyond a very small contained spill. In Myrtle Beach, SC, local crews average a 42-minute response and area rates run $1,725–$9,775.

What Sewage Backup Cleanup Involves
What causes it
- Municipal sewer system backup
- Root infiltration
- Blocked main line
- Heavy storm overwhelm of sewer capacity
- Aging infrastructure failure
How the work is done
- 1Evacuate everyone from the affected area immediately. Sewage contains E. coli, Salmonella, Hepatitis A, Norovirus, and other serious pathogens. Keep children, elderly individuals, and immunocompromised people out of the area entirely until professional cleanup is complete.
- 2Shut off the water supply to stop flow. Turn off the main water supply to prevent additional water from entering drain lines and worsening the backup. Do not run any drains, toilets, or appliances until the blockage is cleared.
- 3Do not use any drains or toilets in the home. Using any drain in the home pushes more sewage into already-backed-up lines. This can worsen the backup and spread contamination further. Wait for professional clearance.
- 4Document the contamination for insurance. Photograph the extent of sewage backup, water lines, and all affected materials. Note the time of discovery. Check your homeowners policy for a sewer backup rider — coverage depends on having this endorsement.
- 5Call a certified sewage cleanup company. Category 3 sewage remediation requires professional-grade PPE, EPA-registered disinfectants, proper disposal of all porous materials (drywall, carpet, insulation), and post-remediation testing. Do not attempt DIY cleanup.
Work follows IICRC S500. Typical duration 5 days; national cost range $2,000–$10,000.

Why Myrtle Beach Homes Face Sewage Backup Cleanup Risks
Local geography, climate, and housing stock all affect how water damage occurs in Myrtle Beach. These are the most common causes our certified teams respond to in this area.
- 1Atlantic Ocean storm surge is the dominant water damage threat for Myrtle Beach; Hurricane Hugo in 1989 and repeated tropical systems since have pushed several feet of seawater across the Grand Strand barrier island and into coastal homes with no elevated foundations.
- 2The Intracoastal Waterway runs directly behind the beachfront strip and rises during coastal storms, flooding low-lying properties from the backside simultaneously with ocean surge from the front.
- 3The Waccamaw River, which drains a massive interior watershed upstream through Conway, backs up and floods low-lying Horry County neighborhoods for weeks after major rain events, as documented extensively during Hurricane Florence in 2018.
- 4Socastee area drainage channels and swales are tidally influenced and experience nuisance flooding during king tides and moderate storms because land elevation is only a few feet above sea level.
- 5Myrtle Beach's sandy coastal soils offer little resistance to groundwater intrusion; during heavy rain events the water table rises to within inches of the surface, saturating crawlspaces and flooding below-grade foundations throughout the city.
Local Risk Notes
The Market Common neighborhood, built on the former Myrtle Beach Air Force Base, sits on relatively flat land with limited natural drainage and has experienced significant flooding during tropical systems including Hurricane Florence. Atlantic Beach and the low-lying sections of Ocean Drive in North Myrtle Beach are especially exposed to combined storm surge and Intracoastal backwater flooding, with many properties having flooded in multiple named storm events.
SC Insurance Tip
In Horry County, private flood insurance carriers have begun withdrawing or dramatically increasing premiums in high-risk coastal zones — get competing quotes from at least two private flood insurers alongside the NFIP before your renewal date, as one may offer substantially lower rates for your specific elevation certificate.
