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.
Ask for credentials before the work starts, not after — a legitimate sewage cleanup specialist will have them ready.
Every sewage job follows documented contamination standards, not an improvised cleanup approach.
We isolate the affected zone before starting any removal to limit cross-contamination.
Contaminated materials get disposed of according to local regulations, not just tossed in a regular dumpster.
Sewage backups get priority dispatch given the health risk involved.
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.
Sewage odor gets treated at the source through disinfection and controlled airflow, not masked with fragrance.
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.
We stand behind the result with a documented sign-off, not just a verbal assurance.
