What to Know
Understanding Sewage Damage
Why Sewage Is a Category 3 Health Hazard
Raw sewage contains bacteria, viruses, parasites, and fungal spores, including E. coli, hepatitis, and salmonella. IICRC S500 classifies it as Category 3, meaning anything it contacted (carpet, pad, drywall below the water line, insulation, particleboard) is typically non-salvageable and must be removed. Do not try to clean it yourself. Our technicians wear full Tyvek suits, P100 respirators, and follow OSHA bloodborne-pathogen protocols. Everything removed is disposed of as regulated waste.
Aging Combined Sewer System in Yonkers
Yonkers has older sewer infrastructure, including combined storm and sanitary lines that overflow during heavy rain. When capacity is exceeded, sewage pushes up through floor drains, toilets, and basement fixtures, especially in lower-elevation neighborhoods. Older clay and cast-iron lateral lines also crack and root-invade, causing single-home backups that are not the city's fault but are still the property owner's problem. We have worked with every pattern of sewer loss in Yonkers.
Multifamily and High-Rise Sewer Backups
Yonkers' density of multifamily and high-rise housing means a single main line backup can affect multiple units, common areas, lower-floor commercial tenants, and shared mechanical spaces simultaneously. Property managers face fast-moving habitability and lease issues, and condo associations face board-level decisions on shared common-area damage. We dispatch crews sized for the loss, coordinate with management and tenants, and deliver documentation that commercial and condo insurance carriers expect.
Extraction, Demolition, Sanitization, Drying
We extract contaminated water with truck-mounted and industrial pumps, remove all non-salvageable porous materials (carpet, pad, affected drywall, insulation), apply EPA-registered antimicrobial to all contacted surfaces, and set commercial dehumidifiers and air movers to dry the structure to safe moisture levels. The drying side of a sewage job is identical to a clean water damage job, and the same crews handle both. We monitor daily with moisture meters until clearance is reached, then we rebuild what was removed.
Mold Risk After a Sewage Event
A sewage backup is one of the highest-risk events for follow-on mold growth, because the water is contaminated and the materials it soaks into are often porous and warm. Without immediate professional drying and antimicrobial treatment, mold can colonize within 48 hours. Our sewage and mold remediation teams coordinate so the structure is properly decontaminated, dried, and verified before any rebuild begins.
We Work With Your Insurance
Sudden sewage backups are often covered by homeowners insurance, especially with a sewer backup endorsement. Coverage varies by carrier and policy, and documentation matters. We bill in Xactimate, the estimating software adjusters require, and our team includes former insurance professionals who know what to document and how to present the claim.
How Sewage Cleanup Works
Our sewage cleanup follows strict safety protocols to protect your health and fully restore your property.
Emergency Response
We dispatch certified technicians within 60 minutes. The affected area is secured and occupants are advised to avoid contact with contaminated materials.
Sewage Extraction
Using specialized equipment and full PPE, we extract all sewage and contaminated water. All affected porous materials that cannot be sanitized, including carpet, drywall, and insulation, are removed and disposed of properly.
Sanitization and Odor Removal
Every affected surface is cleaned with hospital-grade disinfectants. We then perform full odor removal using professional deodorizers and air treatment to eliminate sewage smell completely, not just mask it. HEPA air scrubbers filter airborne contaminants during the entire process.
Structural Drying
Industrial fans and commercial dehumidifiers dry the affected area to limit the possibility of mold growth. We monitor moisture levels daily until everything reaches dry standard.
Rebuild and Restoration
We document everything for your insurance claim and handle direct billing. Then we rebuild the affected area as needed, replacing drywall, flooring, and finishes to restore your property.
