Sewage Backup Cleanup in Long Island

Yes. Raw sewage is classified as Category 3 "black water" and contains bacteria, viruses, parasites, and chemicals that can cause serious illness. Stay out of any affected areas, keep children and pets away, and avoid contact with surfaces, items, or air the sewage may have touched. Call us immediately — our crews arrive in full PPE.

The most common causes are tree-root intrusion in older clay pipes (very common in older Nassau and Suffolk neighborhoods), municipal sewer overflow during heavy rain, sewer-line collapses or offsets, and blockages from grease, wipes, or roots inside the home's plumbing. Heavy storms can overwhelm both private septic systems and municipal lines.

Standard homeowners policies usually do not cover sewer backup unless you have added a specific endorsement (sometimes called sewer-and-drain or water backup coverage). If you have it, the cleanup is typically covered. We help identify your coverage on arrival and document everything for the claim.

Most porous items in direct contact with sewage — drywall, carpet, pad, insulation, upholstered furniture, particleboard, paper goods — must be removed and disposed of for health reasons. Hard, non-porous items (sealed concrete, glazed tile, glass, metal, sealed hardwood) can usually be cleaned and disinfected.

Most residential sewage backup jobs take 4 to 7 days end-to-end: same-day extraction and demolition of contaminated materials, 3 to 5 days of drying and antimicrobial treatment, then rebuild. Larger commercial or multi-room events take longer. We do not close the job until air-quality testing confirms the area is safe.
