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.

Containment goes up before extraction starts, because the goal on a contamination job isn't just removing the water, it's making sure the contamination doesn't spread to rooms that were never affected.
We'd rather explain the sewage cleanup process in plain terms upfront than have you find out the hard way what a shortcut costs later.
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.
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.
Contaminated materials get disposed of according to local regulations, not just tossed in a regular dumpster.
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.
Water gets classified as Category 3 blackwater on arrival, which sets the entire response protocol.
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.
We verify the space meets a safe standard before calling the job complete.
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.
The assessment sets the whole plan, so we don't rush it even when the visible damage looks minor.
Work continues until the job meets our documented completion standard, verified before we call it done.
"They didn't rush the disinfection step even though it clearly slowed the job down."
