A sewage backup in Nashua is a health emergency, not just a mess. 24/7 Water Damage treats it that way. Our crews are IICRC-certified for Category 3 losses and follow OSHA bloodborne pathogen standards with dedicated extraction equipment, hospital-grade antimicrobials at full concentration, and EPA-approved biohazard disposal through licensed haulers.
Our Sewage Cleanup Process
Identify the Backup
We identify and stop the sewage source — shut-off valve, pipe blockage, or municipal issue. The flow has to stop before cleanup can begin.
Hazmat Extraction
Contaminated water gets extracted using sealed equipment separate from our clean-water fleet. Full PPE — Tyvek suits, respirators, rubber boots. No shortcuts on safety.
Remove & Treat
Every porous material that contacted sewage gets removed and properly disposed of. Remaining surfaces are scrubbed and treated with hospital-grade antimicrobials.
Dry & Rebuild
After decontamination, we dry the structure with commercial equipment and rebuild — new drywall, flooring, trim, and paint. Your property comes back clean and safe.

Why Choose 24/7 Water Damage for Sewage Cleanup?
Fast 24/7 Response
Sewage doesn't wait for business hours. Our Nashua crew responds around the clock. The faster we start extraction, the less material needs removing and the lower the restoration cost.
Cause Identification
We don't just clean up — we help identify why it happened. Sewer camera inspection, root assessment, backup prevention recommendations. Fix the cause and it won't happen again.
EPA-Compliant Disposal
Contaminated materials go into sealed biohazard bags and get hauled by licensed waste facilities. Not dumped in a regular dumpster. Proper disposal, documented chain of custody.
Hazmat-Trained Crew
Our sewage cleanup team is trained in IICRC Category 3 protocols and OSHA bloodborne pathogen standards. Full PPE, sealed equipment, proper procedures. This isn't a job for general cleanup crews.

Our Nashua process follows IICRC S500 Category 3 standards: full PPE with Tyvek suits and N95 respirators, sealed extraction, removal of contaminated porous materials, antimicrobial treatment, HEPA filtration, and clearance testing. We also address the cause — sewer camera inspection, root assessment, or backup valve recommendation to prevent recurrence.
