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.
Heavy-Rain Backups in Stamford Basements
Stamford has had repeated heavy-rain events that overwhelm storm drains and sewer mains, pushing sewage up through floor drains, toilets, and basement fixtures across older neighborhoods in Springdale, Glenbrook, Belltown, and downtown. Hurricane Ida and other storm events exposed how quickly combined storm and sewer overflow can fill a residential basement with contaminated water. 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 homeowner's problem.
Multifamily and Commercial Sewer Backups
Multifamily buildings and commercial properties face higher exposure when a main line backs up, because the contamination can affect multiple units, common areas, and lower-floor commercial tenants simultaneously. Downtown Stamford's mix of high-rises, retail, and ground-floor restaurants creates additional exposure. Property managers face fast-moving habitability and lease issues. We dispatch crews sized for the loss, coordinate with management on access and tenant communication, and deliver documentation that commercial carriers expect.
Extraction, Demolition, Sanitization, Drying
We extract contaminated water with industrial pumps and water extractors, 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.
