Sewage backups and drain overflows in Leupp are among the most hazardous water damage events a property can experience. Category 3 black water — raw sewage, backed-up drain lines, toilet overflows — carries bacteria, viruses, and pathogens at concentrations that make any contact a serious health risk. COS Water Damage Restoration's Leupp sewage cleanup team is trained, equipped, and certified under IICRC S520 protocols for Category 3 biohazard remediation — from containment through full restoration.
📞 Call +1-844-499-0972 — Leupp Sewage ResponseSewage cleanup in Leupp 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 Leupp team is certified. The difference is measurable.
Sewage-contaminated materials removed from Leupp properties — carpet, pad, drywall, insulation, and any porous material that absorbed Category 3 water — require regulated waste handling and disposal. Our Leupp crew bags, labels, and disposes of all contaminated material to applicable AZ 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 Leupp crew follows the sequence on every surface, every time.
Our Leupp claim coordinators handle the insurance piece. We can coordinate clearance testing when it's required.
Here's what our certified Leupp Sewage Cleanup crew handles on every job.
Containment is established before extraction begins. This is non-negotiable on every Leupp sewage job.
No material gets dried in place unless it passes decontamination protocol first.
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 Leupp claim coordinators have processed Category 3 claims across AZ 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 Leupp 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.
Containment before contact. Source identified and addressed before cleanup proceeds.
No extraction, no material removal before the written scope is reviewed and approved by you.
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 Leupp 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 Leupp 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 Leupp 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 Leupp, 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."
