When sewage backs up in a Trenton property, the cleanup has to be done correctly from the first step. Incomplete containment, improper material disposal, or skipped sanitization steps leave biological contamination in the structural materials — creating an ongoing health risk long after the visible mess is gone.
📞 Call +1-844-499-0972 — Trenton Sewage ResponseThe four factors that make our Trenton Sewage Cleanup service different from a general water damage company handling a sewage call.
IICRC certification is the standard that defines whether a sewage cleanup was done correctly. Our Trenton team is certified. The difference is measurable.
Proper disposal is a regulatory requirement, not a premium upgrade. It's standard on every Trenton job.
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 Trenton crew follows the sequence on every surface, every time.
Our Trenton claim coordinators handle the insurance piece. We can coordinate clearance testing when it's required.
Here's what our certified Trenton Sewage Cleanup crew handles on every job.
Containment is established before extraction begins. This is non-negotiable on every Trenton sewage job.
No material gets dried in place unless it passes decontamination protocol first.
After material removal, every remaining structural surface — framing, subfloor sheathing, masonry, concrete, and any hard surface that contacted sewage water in your Trenton 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 Trenton team follows is designed to address the pathogen load that Category 3 water deposits on structural surfaces.
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 Trenton 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.
Our Trenton claim coordinators have processed Category 3 claims across OH carriers. We know what gets approved on first submission.
One company from sewage backup to finished reconstruction. No coordination gap, no separate contractor handoff.


Call +1-844-499-0972 and a live Trenton 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.
Containment before contact. Source identified and addressed before cleanup proceeds.
After initial containment and source control, our Trenton 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.
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 Trenton job.



"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 Trenton 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 Trenton 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 Trenton, 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."
