Sewage Backup.
Get Everyone Out.
Then Call Us.
Sewage is a Category 3 biohazard. It contains bacteria, viruses, and pathogens that are immediately dangerous to your family's health. This is not a cleanup job — it is a professional remediation event.
Cleaner Guys provides certified sewage backup cleanup and biohazard remediation across Skagit County. We contain it, extract it, sanitize it, and document it — 24 hours a day.
This Is A Health Emergency
Sewage Isn't Just Unpleasant. It's Biologically Dangerous.
Raw sewage — whether from a backed-up toilet, a failed drain line, or a municipal sewer overflow — is classified as Category 3 black water by the IICRC. It contains E. coli, Hepatitis A, Salmonella, Norovirus, and dozens of other pathogens that cause serious illness through skin contact, inhalation, and indirect exposure.
Children, the elderly, and anyone with a compromised immune system face the highest risk — but no one in the household should be in contact with affected areas until professional remediation is complete and clearance testing confirms the space is safe.
The secondary risk is mold. Sewage water is warm, nutrient-rich, and organic — ideal mold growth conditions. Without complete extraction and antimicrobial treatment, mold colonization begins within 48 hours of a sewage event.
The tertiary risk is your insurance claim. Sewage remediation requires specific documentation protocols to satisfy carrier requirements. Improper or incomplete cleanup — even well-intentioned DIY efforts — can void coverage.
E. coli & Salmonella
Bacterial pathogens present in all sewage events causing severe gastrointestinal illness
Airborne Pathogens
Aerosols from sewage contain viable viral and bacterial particles that are inhaled during exposure
Hepatitis A
A virus transmitted via sewage contact that causes serious liver disease
Rapid Mold Growth
Sewage provides the ideal nutrient environment for mold colonization within 24–48 hours
Insurance Voidance Risk
Improper DIY cleanup creates documentation gaps that carriers use to deny or reduce claims
How We Handle It
Certified Sewage Remediation — Step By Step
Every sewage cleanup follows strict IICRC Category 3 protocols — fully documented for your insurance carrier from first arrival to final clearance.
Containment & Safety Setup
Before any extraction begins, we establish physical containment barriers and negative air pressure to prevent cross-contamination to unaffected areas. All technicians work in full PPE — respirators, Tyvek suits, and chemical-resistant gloves — from first entry to final clearance.
Sewage Extraction & Removal
Industrial extraction equipment removes all standing sewage and black water. All extracted material is handled and disposed of in compliance with Skagit County biohazard disposal regulations — nothing is sent into the municipal drain system.
Contaminated Material Removal
Porous materials that have been contacted by sewage — drywall, insulation, flooring, subflooring, and cabinetry — cannot be sanitized and must be removed. We document all removed materials for your insurance claim before disposal.
Disinfection & Antimicrobial Treatment
All affected structural surfaces receive hospital-grade disinfectant treatment followed by EPA-registered antimicrobial application. This kills active pathogens and inhibits mold colonization in the treated area.
Structural Drying & Dehumidification
After disinfection, industrial air movers and dehumidifiers run continuously until moisture readings confirm the structure has reached dry standard. We monitor daily and adjust equipment until clearance criteria are met.
Clearance Testing & Documentation
Upon completion, we provide a full remediation report including pre/post photos, moisture readings, product application records, and disposal documentation. This package satisfies carrier requirements and gives you a certified clean bill of health for the space.
What Causes Sewage Backup
It's More Common Than You Think
Sewage backup is not always the result of neglect. Many causes are outside the homeowner's control — and most are covered by insurance when properly documented.
Municipal Sewer Overflow
Heavy rainfall overwhelms city sewer infrastructure and reverses flow into residential lines.
Tree Root Intrusion
Root systems infiltrate and crack older clay or cast-iron drain lines underground.
Drain Line Blockage
Accumulation of grease, wipes, and debris creates complete blockages that force sewage backward.
Failed or Collapsed Pipe
Aging or improperly installed sewer lines crack, collapse, or separate underground.
Sump Pump Failure
Failed sump pumps during rain events allow groundwater and sewage to enter basements.
Improperly Vented Plumbing
Negative pressure in drain lines creates siphoning that pulls sewage back through fixtures.
Insurance Coverage
Sewage Backup Is Covered Under Most Homeowner Policies — If It's Documented Correctly.
Most standard homeowner insurance policies include sewage backup and sewer line coverage as either a base provision or an endorsement. The critical variable is documentation. Carriers require specific evidence — the source of the backup, the extent of contamination, material removal records, and remediation protocols followed — to process the claim.
This is where improper DIY cleanup creates serious problems. If materials are removed, areas are bleached, or fans are run before a professional assessment, the documentation trail is broken and carriers frequently use that gap to dispute or deny coverage.
Cleaner Guys arrives first, documents everything before any work begins, and produces a complete insurance package from that first visit forward. We've successfully supported sewage backup claims with virtually every major carrier serving Skagit County.
Even if you're unsure about your coverage, call us first. We can review the situation, document what's present, and help you understand what your policy likely covers — at no cost to you.
What Customers Say
Skagit County Trusts Cleaner Guys With The Worst Of It
"Our basement toilet backed up while we were at work. By the time we got home it had been running for hours. I was panicked. Cleaner Guys was there within the hour, had everything contained and extracted the same night, and handled all the insurance paperwork. Professional doesn't even begin to cover it."
— Greg T., Mount Vernon, WA

"I manage twelve residential units. Sewage events happen. Cleaner Guys is the only company I trust to handle them correctly — proper containment, correct disposal, full documentation, and they're always there when I call. They've saved me from several potential liability situations."
