Why Choose Us

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

The four factors that make our Hillsdale 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 Hillsdale team is certified. The difference is measurable.

🚫

Regulated Disposal

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

💧

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

Sewage cleanup claims in Hillsdale typically proceed under homeowner's policy coverage for drain backup and water damage. Our Hillsdale 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.

Services

Sewage Cleanup Services Our Hillsdale Team Performs

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

☢

Containment Setup & Source Control

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

🚫

Category 3 Extraction & Material Removal

Extracting Category 3 sewage water from a Hillsdale 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 Hillsdale 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 Hillsdale 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 Hillsdale claim coordinators have processed Category 3 claims across MI 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.

Our Process

How Sewage Cleanup Works in Hillsdale — Category 3 Protocol

Call — Biohazard Dispatch

Call +1-844-499-0972 and a live Hillsdale 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 Hillsdale 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

Hillsdale Customers on Our Sewage Cleanup Service

★★★★★

"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 Hillsdale 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."

★★★★★

"The thing that stood out with COS Water Damage Restoration's Hillsdale 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 Hillsdale, 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 Hillsdale

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

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

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

Does homeowner's insurance cover sewage backup in Hillsdale?

Coverage for sewage backup events in Hillsdale 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 Hillsdale 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 Hillsdale?

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

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

Can I stay in my Hillsdale home during sewage cleanup?

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

This area is located in the rolling, fertile hills of South Central Michigan, bordering Indiana and Ohio, according to the boundaries set up under United States settlement. It was long occupied by the Potowatomi, an Algonquian-speaking people who were part of a long-term alliance, called the Council of Three Fires, with the Ojibwe and Odawa (Ottawa). A Potowatomi band of about 150 people, led by the chief known as Baw Beese, had a base camp near the large lake in the area.
