Why Choose Us

What Sets COS Water Damage Restoration Apart for Sewage Cleanup in Marietta

The four factors that make our Marietta Sewage Cleanup service different from a general water damage company handling a sewage call.

☢

IICRC S520 Category 3

COS Water Damage Restoration's Marietta sewage cleanup crew operates under IICRC S520 standard — the industry's governing protocol for Category 3 contaminated water remediation. This covers the specific containment requirements, the PPE standards that protect our crew from pathogen exposure, the material removal requirements (what can be safely dried versus what must be removed and disposed of as a regulated waste stream), and the multi-application antimicrobial sanitization protocol that must be completed before any structural drying begins.

🚫

Regulated Disposal

Sewage-contaminated materials removed from Marietta properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our Marietta crew bags, labels, and disposes of all contaminated material to applicable OK regulatory requirements. No dumping in standard refuse. No leaving contaminated materials in dumpsters that aren't rated for biohazard waste.

💧

Hospital-Grade Sanitization

One application of sanitizer after a sewage event is not sufficient. Our protocol uses multiple applications with documented dwell times.

📋

Insurance & Air Quality Coordination

Our Marietta claim coordinators handle the insurance piece. We can coordinate clearance testing when it's required.

Services

Sewage Cleanup Services Our Marietta Team Performs

COS Water Damage Restoration handles the complete scope of Sewage Cleanup in Marietta — from containment and extraction through material removal, sanitization, structural drying, and rebuild. Category 3 protocols, start to finish.

☢

Containment Setup & Source Control

Containment is established before extraction begins. This is non-negotiable on every Marietta sewage job.

🚫

Category 3 Extraction & Material Removal

Extracting Category 3 sewage water from a Marietta property requires specific PPE — full protective suits, respirators rated for biological hazard, and disposable boots — for every technician in the contamination zone. We use dedicated contaminated-water extraction equipment that is not shared with standard water damage jobs and is properly sanitized between uses. After extraction, all materials that contacted Category 3 water and cannot be decontaminated to a safe standard — carpet, pad, standard drywall, fiberglass insulation, and any non-cleanable surface materials — are removed as regulated waste, bagged in approved containers, and disposed of under OK biohazard material regulations.

💧

Multi-Phase Antimicrobial Sanitization

After material removal, every remaining structural surface — framing, subfloor sheathing, masonry, concrete, and any hard surface that contacted sewage water in your Marietta property — receives a multi-phase sanitization treatment using EPA-registered, hospital-grade antimicrobial and antifungal agents. The sanitization sequence includes spray application, documented dwell time, surface contact, and at minimum one additional application after the first dwell cycle. This is not a one-spray process. The S520 protocol our Marietta team follows is designed to address the pathogen load that Category 3 water deposits on structural surfaces.

💨

Odor Neutralization & Air Treatment

Odor neutralization is a final treatment step, not a product sprayed at the end to cover incomplete remediation.

📋

Insurance & Backup Coverage Claims

Our Marietta claim coordinators have processed Category 3 claims across OK carriers. We know what gets approved on first submission.

🏠

Post-Remediation Reconstruction

One company from sewage backup to finished reconstruction. No coordination gap, no separate contractor handoff.

Reviews

Marietta Customers on Our Sewage Cleanup Service

★★★★★

"When our basement drain backed up in Marietta, I didn't realize I was dealing with a sewage event until the smell made it obvious. COS Water Damage Restoration arrived within the hour, set up containment before anyone entered the space, and explained the Category 3 protocols clearly — including why certain materials had to be removed and couldn't just be dried in place. They disposed of everything properly, treated all surfaces with a sanitization protocol I could actually track through each step, and filed the insurance claim the same day. The reconstruction brought the basement back completely. I feel good about the space now, and that was not a given after the event."

"The thing that stood out with COS Water Damage Restoration's Marietta sewage cleanup team was the containment setup — I've seen other companies skip it or do it loosely, and you can tell they don't understand why it matters. This team had proper negative-pressure containment up before they extracted a gallon of water. The two-phase sanitization after material removal, the hydroxyl generator running during drying, the final surface swab coordination — this was a Category 3 remediation done to the actual standard, not a watered-down version of it."

"I've used general contractors for water damage before with mixed results. After calling COS Water Damage Restoration for a sewage event in Marietta, 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."

FAQs

Common Questions — Sewage Cleanup in Marietta

Why is sewage water treated as a biohazard in Marietta properties?

Sewage water — including backed-up drain water, raw sewage, and toilet overflow contents — is classified as Category 3 under the IICRC S500 water damage standard. Category 3 water is defined as grossly contaminated and contains pathogenic bacteria, viruses, parasites, and other biological agents at levels that pose a direct health risk to humans and animals. Contact without appropriate PPE, breathing air in an uncontained Category 3 space, and exposure of household members to inadequately remediated surfaces are all real health risks. This is why proper containment, full PPE, and compliant sanitization are non-negotiable steps in Marietta sewage cleanup — not optional upgrades.

What materials are removed versus saved during Sewage Cleanup in Marietta?

Under IICRC S520 Category 3 protocol, porous materials that contacted sewage water and cannot be decontaminated to a safe standard are removed as regulated waste. In a typical Marietta sewage event, this includes: carpet and pad (always), standard wallboard drywall that was submerged or splashed, standard fiberglass or cellulose insulation, and any other porous finish material that absorbed Category 3 water. Hard, non-porous surfaces — concrete, ceramic tile, metal framing, pressure-treated lumber — can typically be decontaminated in place using the sanitization protocol. Our Marietta project manager evaluates each material individually and documents the removal decision in the written scope.

Does homeowner's insurance cover sewage backup in Marietta?

Coverage for sewage backup events in Marietta typically depends on whether your homeowner's policy includes a backup coverage rider. Standard homeowner's policies generally exclude sewer and drain backup damage unless this specific rider is included. Backup coverage riders are relatively inexpensive to add and cover most drain backup events. Our Marietta claim coordinators review your policy details and document your claim to match your specific coverage terms — including the important distinction between a backup event and a sewer line failure, which may be covered differently.

Is clearance testing required after Sewage Cleanup in Marietta?

Third-party clearance testing — air quality and surface swab sampling performed by an independent industrial hygienist — is not universally required after sewage cleanup in Marietta, but it is available and appropriate in several situations: commercial properties with regulatory requirements, rental properties where a landlord needs documented proof of remediation for tenants, situations where immunocompromised individuals occupy the property, or any case where a client wants independent verification beyond our own completion documentation. We coordinate third-party clearance testing on request and can schedule it immediately after the final sanitization cycle.

How long does Sewage Cleanup take in Marietta?

A typical Marietta sewage cleanup project runs: Day 1 for containment, extraction, and material removal; Days 1-2 for sanitization cycle (multiple applications with documented dwell times); Days 2-6 for structural drying under daily monitoring; clearance testing coordination if needed (24-48 hours for lab results); and then reconstruction, which ranges from a few days to several weeks depending on the scope of material removed. Your Marietta project manager provides a realistic timeline at the initial assessment and updates it as the drying program progresses.

Can I stay in my Marietta home during sewage cleanup?

Whether you can remain in your Marietta home during sewage cleanup depends on the contamination zone and the containment configuration our team establishes. For events confined to a basement or a single room where negative-pressure containment can isolate the remediation area from the occupied portions of the home, remaining in place is often feasible. For events that affect living areas, bedrooms, or the main floor, temporary relocation is strongly recommended during the active remediation phase — typically 1-3 days. Our Marietta project manager evaluates the specific situation and advises on habitability at the initial assessment.
