If sewage backed up into your Merrimack property, stop walking through it. Sewage contains E. coli, hepatitis A, rotavirus, and dozens of other pathogens. Our hazmat-trained crew arrives in full PPE with dedicated equipment that never touches clean-water jobs. We extract contamination, remove affected materials, and sanitize to a safe level.
Our Sewage Cleanup Process
Stop the Flow
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
Our hazmat crew pumps out contaminated water using dedicated equipment with sealed discharge. Cross-contamination prevention is non-negotiable on sewage jobs.
Material Removal & Decontamination
Every porous material that contacted sewage gets removed and properly disposed of. Remaining surfaces are scrubbed and treated with hospital-grade antimicrobials.
Restore Your Property
Once the structure is decontaminated and dry, our crew handles the full rebuild. New materials, fresh finishes, and peace of mind that the contamination is completely gone.

About Our Merrimack Sewage Cleanup Services
The danger with sewage isn't just what you see — contaminants soak into drywall, subfloor, and concrete. Our crew cuts drywall 12-24 inches above the highest visible contamination because wicking carries bacteria higher than the waterline. Removed materials get bagged, sealed, and disposed through licensed biohazard haulers.
After 15 years cleaning sewage events in Merrimack, we've seen every cause: root intrusion, aging clay pipes, grinder pump failures, main backups, grease blockages. We address the contamination and the cause. Sewer camera inspection or root removal coordinated too. Call (866) 993-3605.
