Sewage backups and drain overflows in Guadalupe 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 Guadalupe 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 — Guadalupe Sewage ResponseThe four factors that make our Guadalupe 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 Guadalupe team is certified. The difference is measurable.
Proper disposal is a regulatory requirement, not a premium upgrade. It's standard on every Guadalupe job.
One application of sanitizer after a sewage event is not sufficient. Our protocol uses multiple applications with documented dwell times.
Our Guadalupe claim coordinators handle the insurance piece. We can coordinate clearance testing when it's required.
COS Water Damage Restoration handles the complete scope of Sewage Cleanup in Guadalupe — from containment and extraction through material removal, sanitization, structural drying, and rebuild. Category 3 protocols, start to finish.
Containment is established before extraction begins. This is non-negotiable on every Guadalupe 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 Guadalupe 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 Guadalupe team follows is designed to address the pathogen load that Category 3 water deposits on structural surfaces.
Odor neutralization is a final treatment step, not a product sprayed at the end to cover incomplete remediation.
Our Guadalupe 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 Guadalupe 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.


Call +1-844-499-0972 and a live Guadalupe 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.
Our Guadalupe 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 Guadalupe 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 Guadalupe 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 Guadalupe 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 Guadalupe 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 Guadalupe 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."
