Sewage backups and drain overflows in Hollywood 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 Hollywood 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 — Hollywood Sewage ResponseSewage cleanup in Hollywood 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 Hollywood team is certified. The difference is measurable.
Proper disposal is a regulatory requirement, not a premium upgrade. It's standard on every Hollywood job.
One application of sanitizer after a sewage event is not sufficient. Our protocol uses multiple applications with documented dwell times.
Our Hollywood 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 Hollywood — from containment and extraction through material removal, sanitization, structural drying, and rebuild. Category 3 protocols, start to finish.
The first action our Hollywood sewage crew takes on any Category 3 event is establishing negative-pressure containment — critical plastic sheeting barriers that prevent sewage contamination from spreading into unaffected areas of the property through airborne particles, foot traffic, and air circulation. Containment also controls odor migration within the property while remediation is underway. Simultaneously, we identify and coordinate the correction of the blockage or failure that caused the backup — whether that's a main line obstruction, a failed cleanout, or a sump failure — so that remediation isn't interrupted by a secondary event.
Extracting Category 3 sewage water from a Hollywood 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 SC 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 Hollywood claim coordinators have processed Category 3 claims across SC carriers. We know what gets approved on first submission.
One company from sewage backup to finished reconstruction. No coordination gap, no separate contractor handoff.


Sewage events require immediate evacuation of affected areas. Our dispatcher will confirm this on the call.
Our Hollywood 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.
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 Hollywood job.



"When our basement drain backed up in Hollywood, 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."
"Three years later, no odor, no mold, no recurring issues. COS Water Damage Restoration did the Hollywood sewage cleanup right the first time. I'm telling every neighbor I know to call them first."
"Managing a rental property in Hollywood 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."
