Why Choose Us

What Sets COS Water Damage Restoration Apart for Sewage Cleanup in North Hills

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

☢

IICRC S520 Category 3

COS Water Damage Restoration's North Hills 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 North Hills properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our North Hills crew bags, labels, and disposes of all contaminated material to applicable CA regulatory requirements. No dumping in standard refuse. No leaving contaminated materials in dumpsters that aren't rated for biohazard waste.

💧

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 North Hills crew follows the sequence on every surface, every time.

📋

Insurance & Air Quality Coordination

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

Services

Sewage Cleanup Services Our North Hills Team Performs

COS Water Damage Restoration handles the complete scope of Sewage Cleanup in North Hills — 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 North Hills sewage job.

🚫

Category 3 Extraction & Material Removal

Extracting Category 3 sewage water from a North Hills 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 CA biohazard material regulations.

💧

Multi-Phase Antimicrobial Sanitization

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

💨

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 North Hills claim coordinators have processed Category 3 claims across CA 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 North Hills 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 North Hills — Category 3 Protocol

Call — Biohazard Dispatch

Sewage events require immediate evacuation of affected areas. Our dispatcher will confirm this on the call.

Arrival — Containment First

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

Assessment & Written Scope

After initial containment and source control, our North Hills 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

North Hills Customers on Our Sewage Cleanup Service

★★★★★

"When our basement drain backed up in North Hills, 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 North Hills 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."

★★★★★

"Managing a rental property in North Hills 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 North Hills

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

What materials are removed versus saved during Sewage Cleanup in North Hills?

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

Does homeowner's insurance cover sewage backup in North Hills?

Coverage for sewage backup events in North Hills 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 North Hills 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 North Hills?

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

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

Can I stay in my North Hills home during sewage cleanup?

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