Why Choose Us

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

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

☢

IICRC S520 Category 3

IICRC certification is the standard that defines whether a sewage cleanup was done correctly. Our Clawson team is certified. The difference is measurable.

🚫

Regulated Disposal

Proper disposal is a regulatory requirement, not a premium upgrade. It's standard on every Clawson job.

💧

Hospital-Grade Sanitization

After contaminated material is removed and Category 3 extraction is complete, every structural surface that contacted sewage water receives multiple applications of EPA-registered, hospital-grade antimicrobial and antifungal treatments. The sanitization sequence — spray application, dwell time, surface wipe-down, second application — is protocol-driven, not judgment-call driven. Our Clawson crew follows the sequence on every surface, every time.

📋

Insurance & Air Quality Coordination

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

Services

Sewage Cleanup Services Our Clawson Team Performs

Here's what our certified Clawson Sewage Cleanup crew handles on every job.

☢

Containment Setup & Source Control

The first action our Clawson sewage crew takes on any Category 3 event is establishing negative-pressure containment — critical plastic sheeting barriers that prevent sewage contamination from spreading into unaffected areas of the property through airborne particles, foot traffic, and air circulation. Containment also controls odor migration within the property while remediation is underway. Simultaneously, we identify and coordinate the correction of the blockage or failure that caused the backup — whether that's a main line obstruction, a failed cleanout, or a sump failure — so that remediation isn't interrupted by a secondary event.

🚫

Category 3 Extraction & Material Removal

Extracting Category 3 sewage water from a Clawson 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 MI 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 Clawson 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 Clawson team follows is designed to address the pathogen load that Category 3 water deposits on structural surfaces.

💨

Odor Neutralization & Air Treatment

Category 3 sewage events leave odor-causing compounds embedded in structural materials, in the air space above the affected area, and — in HVAC systems — potentially distributed throughout the property. Our Clawson team uses hydroxyl generator technology and botanical-based counteractant treatments to neutralize sewage odor compounds in the air and on surfaces, not mask them. For properties where HVAC ductwork may have been exposed to Category 3 contamination, duct isolation and decontamination is included in our scope evaluation.

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

Our Process

How Sewage Cleanup Works in Clawson — Category 3 Protocol

Call — Biohazard Dispatch

Call +1-844-499-0972 and a live Clawson 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.

Arrival — Containment First

Containment before contact. Source identified and addressed before cleanup proceeds.

Assessment & Written Scope

After initial containment and source control, our Clawson project manager assesses the full Category 3 contamination extent, identifies all materials requiring removal, and prepares a written Xactimate-based scope covering extraction, material removal, sanitization, structural drying, and reconstruction. You review the scope and the cost before any material removal or treatment begins. If insurance is involved, the claim is filed the same day.

Remediation & Rebuild

From sewage event to finished property — documented, guaranteed, and handled by one company.

Reviews

Clawson Customers on Our Sewage Cleanup Service

★★★★★

"When our basement drain backed up in Clawson, 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."

"Three years later, no odor, no mold, no recurring issues. COS Water Damage Restoration did the Clawson sewage cleanup right the first time. I'm telling every neighbor I know to call them first."

★★★★★

"Managing a rental property in Clawson means sewage backups occasionally happen, and the response you choose matters enormously because you have tenant health and habitability on the line. COS Water Damage Restoration handled a Category 3 event at one of our properties with complete transparency — documented scope before work started, clear removal decisions explained in writing, and a clearance certificate at the end that we could show our tenant as proof the property was properly remediated. The insurance claim was settled without any dispute."

FAQs

Common Questions — Sewage Cleanup in Clawson

Why is sewage water treated as a biohazard in Clawson 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 Clawson sewage cleanup — not optional upgrades.

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

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 Clawson 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 Clawson project manager evaluates each material individually and documents the removal decision in the written scope.

Does homeowner's insurance cover sewage backup in Clawson?

Coverage for sewage backup events in Clawson 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 Clawson 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 Clawson?

Third-party clearance testing — air quality and surface swab sampling performed by an independent industrial hygienist — is not universally required after sewage cleanup in Clawson, 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 Clawson?

A typical Clawson 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 Clawson project manager provides a realistic timeline at the initial assessment and updates it as the drying program progresses.

Can I stay in my Clawson home during sewage cleanup?

Whether you can remain in your Clawson 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 Clawson project manager evaluates the specific situation and advises on habitability at the initial assessment.
