Why Choose Us

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

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

🚫

Regulated Disposal

Sewage-contaminated materials removed from Madison properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our Madison crew bags, labels, and disposes of all contaminated material to applicable NJ 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 Madison claim coordinators handle the insurance piece. We can coordinate clearance testing when it's required.

Services

Sewage Cleanup Services Our Madison Team Performs

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

☢

Containment Setup & Source Control

The first action our Madison 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 Madison 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 NJ biohazard material regulations.

💧

Multi-Phase Antimicrobial Sanitization

Sanitization happens before drying equipment is staged. This sequence matters.

💨

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 Madison 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.

📋

Insurance & Backup Coverage Claims

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

🏠

Post-Remediation Reconstruction

After Category 3 remediation is confirmed complete by instrument readings and — where required — by third-party clearance testing, our licensed Madison reconstruction team rebuilds your property: new drywall, fresh insulation, flooring, paint, trim, and any affected cabinetry or millwork. All reconstruction is performed to the same documentation standard as the remediation phase, providing a complete recovery record from sewage event to finished property that your insurance carrier and any future property transaction will find clear and complete.

Our Process

How Sewage Cleanup Works in Madison — Category 3 Protocol

Call — Biohazard Dispatch

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

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 Madison job.

Reviews

Madison 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 Madison 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 Madison 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 Madison, 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 Madison

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

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

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

Does homeowner's insurance cover sewage backup in Madison?

Coverage for sewage backup events in Madison 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 Madison 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 Madison?

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

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

Can I stay in my Madison home during sewage cleanup?

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