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.
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.
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.
Every piece of sewage cleanup work below follows the same documentation standard, whether it's a small job or a larger one.
Classification determines PPE level, containment approach, and which materials must be removed.
Extraction equipment dedicated to contaminated water keeps cross-contamination from clean-water jobs.
Carpet, pad, and drywall that contacted blackwater almost always require removal rather than drying in place.
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.
Four steps, no guesswork, from your first call to a verified sewage cleanup result.
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.
A job isn't closed on a visual check — it's closed on a verified reading.
