A sewage backup isn't a job for a mop and bucket. Our Sewage Cleanup crews arrive in full PPE, classify the contamination, and follow IICRC S500 blackwater protocols from the first step.

The decision to remove a material rather than dry it in place isn't a cost-cutting call on a sewage job — it's a safety standard, since porous materials that contact blackwater can't be fully sanitized no matter how long you dry them.
None of this is unique to a big loss either — the same standard applies whether it's a single-room sewage cleanup call or a larger one.
We built this list around what typically goes wrong when sewage cleanup gets handled by a generalist rather than a specialist.
None of these standards are unique to us in theory, but they're worth confirming before you let anyone start sewage cleanup work on your property.
S500 protocol governs PPE, containment, and disposal on every Category 3 call we handle.
Technicians suit up in full protective gear before entering a contaminated area.
Disposal documentation is provided as part of the job record.
We treat contamination calls with urgency, since delay increases exposure risk.
We don't treat sewage cleanup as a single generic task — each part of the process below gets its own specific approach.
Classification determines PPE level, containment approach, and which materials must be removed.
We extract with full PPE and controlled disposal of extracted contaminated water.
Porous materials can't be fully sanitized after blackwater contact, which is a safety call, not a cost-cutting one.
Every surface that had contact with contaminated water gets disinfected with hospital-grade antimicrobial treatment.
We address the contamination causing the odor rather than just deploying an air freshener.
Final verification includes both moisture and contamination checks before sign-off.
This is the same sequence every sewage cleanup job follows, regardless of size.
Dispatch gathers just enough detail to load the right equipment before the truck leaves.
Local staging is what makes rapid arrival possible, rather than a promise with nothing behind it.
A technician assesses the scope on-site and provides a written flat-rate quote before any work begins.
A job isn't closed on a visual check — it's closed on a verified reading.
"They didn't rush the disinfection step even though it clearly slowed the job down."

Preston G., Somerville"Disposal documentation came through clean and organized for our property records."
Victor N., Somerville"Full PPE and proper containment meant we could reopen the rest of the dining room the same evening."
