Why Choose Us

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

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

☢

IICRC S520 Category 3

COS Water Damage Restoration's Lanham 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 Lanham 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 Lanham typically proceed under homeowner's policy coverage for drain backup and water damage. Our Lanham 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 Lanham Team Performs

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

☢

Containment Setup & Source Control

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

🚫

Category 3 Extraction & Material Removal

Extracting Category 3 sewage water from a Lanham 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 MD 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

Most MD homeowner's policies cover sewage backup events under a backup coverage rider. Our Lanham 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 Lanham 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 Lanham — 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 Lanham 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

Lanham Customers on Our Sewage Cleanup Service

★★★★★

"When our basement drain backed up in Lanham, 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 Lanham 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 Lanham, 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 Lanham

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

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

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

Does homeowner's insurance cover sewage backup in Lanham?

Coverage for sewage backup events in Lanham 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 Lanham 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 Lanham?

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

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

Can I stay in my Lanham home during sewage cleanup?

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