Sewage backups and drain overflows in Hampton are among the most hazardous water damage events a property can experience. Category 3 black water — raw sewage, backed-up drain lines, toilet overflows — carries bacteria, viruses, and pathogens at concentrations that make any contact a serious health risk. COS Water Damage Restoration's Hampton sewage cleanup team is trained, equipped, and certified under IICRC S520 protocols for Category 3 biohazard remediation — from containment through full restoration.
📞 Call +1-844-499-0972 — Hampton Sewage ResponseThe four factors that make our Hampton Sewage Cleanup service different from a general water damage company handling a sewage call.
IICRC certification is the standard that defines whether a sewage cleanup was done correctly. Our Hampton team is certified. The difference is measurable.
Sewage-contaminated materials removed from Hampton properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our Hampton crew bags, labels, and disposes of all contaminated material to applicable MN regulatory requirements. No dumping in standard refuse. No leaving contaminated materials in dumpsters that aren't rated for biohazard waste.
One application of sanitizer after a sewage event is not sufficient. Our protocol uses multiple applications with documented dwell times.
Sewage cleanup claims in Hampton typically proceed under homeowner's policy coverage for drain backup and water damage. Our Hampton coordinators are experienced with backup coverage riders and know how to document Category 3 events for claim approval. For commercial properties or clients requiring clearance testing, we coordinate third-party air quality and surface sampling after remediation to provide a written clearance certificate before reconstruction begins.
COS Water Damage Restoration handles the complete scope of Sewage Cleanup in Hampton — from containment and extraction through material removal, sanitization, structural drying, and rebuild. Category 3 protocols, start to finish.
Containment is established before extraction begins. This is non-negotiable on every Hampton sewage job.
No material gets dried in place unless it passes decontamination protocol first.
Sanitization happens before drying equipment is staged. This sequence matters.
Odor neutralization is a final treatment step, not a product sprayed at the end to cover incomplete remediation.
Most MN homeowner's policies cover sewage backup events under a backup coverage rider. Our Hampton claim coordinators are familiar with the specific documentation that backup claims require — including the distinction between backup events (covered) and sewer line failures (may require separate coverage) — and build your claim file from the first day to match what your carrier's adjuster will look for. We file the claim, coordinate the adjuster visit, and follow the settlement through. You focus on your household; we handle the insurance.
One company from sewage backup to finished reconstruction. No coordination gap, no separate contractor handoff.


Call +1-844-499-0972 and a live Hampton dispatcher answers — not a recording. Describe the situation; our dispatcher confirms the sewage backup details, dispatches the nearest Category 3-equipped crew, and confirms estimated arrival. Evacuate the affected area and prevent household members and pets from entering while we're en route.
Containment before contact. Source identified and addressed before cleanup proceeds.
No extraction, no material removal before the written scope is reviewed and approved by you.
Extraction, material removal, multi-phase sanitization, structural drying, and reconstruction proceed under your approved scope. Daily progress updates keep you informed. Clearance testing is coordinated where required or requested. Final sign-off at a walkthrough with your project manager. Written satisfaction guarantee on every Hampton job.



"We have a young child and a dog and the moment the sewage smell hit I knew this was something I couldn't handle myself. COS Water Damage Restoration's Hampton team was there in under 60 minutes, contained the area so our family could stay in the upper floors, and handled every part of the cleanup in a way I trusted. The clearance testing they coordinated at the end gave me documented proof that the remediation was complete."
"Three years later, no odor, no mold, no recurring issues. COS Water Damage Restoration did the Hampton sewage cleanup right the first time. I'm telling every neighbor I know to call them first."
"I've used general contractors for water damage before with mixed results. After calling COS Water Damage Restoration for a sewage event in Hampton, I understand the difference between a certified Category 3 remediation team and a general restoration company that 'also does sewage.' The protocols aren't comparable."
