When sewage backs up in a Nunn 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 — Nunn Sewage ResponseSewage cleanup in Nunn is not a standard water damage job. The contamination levels, regulated disposal requirements, containment procedures, and sanitization standards that apply to Category 3 events are fundamentally different — and using a company without specific Category 3 training and equipment leaves your property and your household at risk.
IICRC certification is the standard that defines whether a sewage cleanup was done correctly. Our Nunn team is certified. The difference is measurable.
Sewage-contaminated materials removed from Nunn properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our Nunn crew bags, labels, and disposes of all contaminated material to applicable CO regulatory requirements. No dumping in standard refuse. No leaving contaminated materials in dumpsters that aren't rated for biohazard waste.
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 Nunn crew follows the sequence on every surface, every time.
Sewage cleanup claims in Nunn typically proceed under homeowner's policy coverage for drain backup and water damage. Our Nunn 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.
Here's what our certified Nunn Sewage Cleanup crew handles on every job.
Containment is established before extraction begins. This is non-negotiable on every Nunn sewage job.
Extracting Category 3 sewage water from a Nunn 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 CO biohazard material regulations.
Sanitization happens before drying equipment is staged. This sequence matters.
Odor neutralization is a final treatment step, not a product sprayed at the end to cover incomplete remediation.
Our Nunn claim coordinators have processed Category 3 claims across CO carriers. We know what gets approved on first submission.
After Category 3 remediation is confirmed complete by instrument readings and — where required — by third-party clearance testing, our licensed Nunn 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.


Sewage events require immediate evacuation of affected areas. Our dispatcher will confirm this on the call.
Our Nunn 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.
After initial containment and source control, our Nunn 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 Nunn 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 Nunn 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."
"Three years later, no odor, no mold, no recurring issues. COS Water Damage Restoration did the Nunn sewage cleanup right the first time. I'm telling every neighbor I know to call them first."
"I've used general contractors for water damage before with mixed results. After calling COS Water Damage Restoration for a sewage event in Nunn, 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."
