Why Choose Us

What Sets COS Water Damage Restoration Apart for Sewage Cleanup in Old Westbury

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

☢

IICRC S520 Category 3

COS Water Damage Restoration's Old Westbury 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

Proper disposal is a regulatory requirement, not a premium upgrade. It's standard on every Old Westbury 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 Old Westbury typically proceed under homeowner's policy coverage for drain backup and water damage. Our Old Westbury 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 Old Westbury Team Performs

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

🚫

Category 3 Extraction & Material Removal

No material gets dried in place unless it passes decontamination protocol first.

💧

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 Old Westbury 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

Most NY homeowner's policies cover sewage backup events under a backup coverage rider. Our Old Westbury claim coordinators are familiar with the specific documentation that backup claims require — including the distinction between backup events (covered) and sewer line failures (may require separate coverage) — and build your claim file from the first day to match what your carrier's adjuster will look for. We file the claim, coordinate the adjuster visit, and follow the settlement through. You focus on your household; we handle the insurance.

🏠

Post-Remediation Reconstruction

After Category 3 remediation is confirmed complete by instrument readings and — where required — by third-party clearance testing, our licensed Old Westbury 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 Old Westbury — Category 3 Protocol

02

Arrival — Containment First

Our Old Westbury crew arrives in full Category 3 PPE with containment materials, dedicated contaminated-water extraction equipment, and sanitization products. Containment is established before extraction begins — no exceptions. After containment, we identify the source of the backup and coordinate correction if needed before the cleanup scope is assessed.

03

Assessment & Written Scope

No extraction, no material removal before the written scope is reviewed and approved by you.

04

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 Old Westbury job.

Old Westbury 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 Old Westbury 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 Old Westbury 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 Old Westbury 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 Old Westbury

Why is sewage water treated as a biohazard in Old Westbury 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 Old Westbury sewage cleanup — not optional upgrades.
What materials are removed versus saved during Sewage Cleanup in Old Westbury?
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 Old Westbury 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 Old Westbury project manager evaluates each material individually and documents the removal decision in the written scope.
Does homeowner's insurance cover sewage backup in Old Westbury?
Coverage for sewage backup events in Old Westbury 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 Old Westbury 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 Old Westbury?
Third-party clearance testing — air quality and surface swab sampling performed by an independent industrial hygienist — is not universally required after sewage cleanup in Old Westbury, 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 Old Westbury?
A typical Old Westbury 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 Old Westbury project manager provides a realistic timeline at the initial assessment and updates it as the drying program progresses.
Can I stay in my Old Westbury home during sewage cleanup?
Whether you can remain in your Old Westbury 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 Old Westbury project manager evaluates the specific situation and advises on habitability at the initial assessment.
