Category 3 blackwater is a health hazard, not a cleaning job. Our Sewage Cleanup crews arrive in full PPE and follow IICRC S500 protocol from the first step, not just the parts that are convenient.

Containment goes up before extraction starts, because the goal isn't just removing the water, it's making sure contamination doesn't spread into rooms that were never affected.
None of this changes for a small job 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 instead of a specialist.
S500 governs PPE, containment, and disposal on every Category 3 call we take.
Technicians suit up in complete protective gear before entering any contaminated zone.
Contaminated materials are disposed of per local regulation, not just tossed in a standard bin.
Sewage calls get priority dispatch given the actual health risk involved.
We don't treat sewage cleanup as a single generic task — each piece of the process below gets its own specific approach.
Water gets classified as Category 3 blackwater immediately, which sets the entire response protocol.
Dedicated extraction equipment prevents cross-contamination from clean-water jobs.
This is a safety call based on contamination science, not a cost-cutting shortcut.
Disinfection follows removal of unsalvageable materials, covering the entire affected zone.
Odor gets addressed through disinfection and controlled airflow, not masked with fragrance.
The space gets verified against a safe standard before we call the job complete.
Four steps, no guesswork, from your first call to a verified sewage cleanup result.
A real person answers, asks a few fast questions, and routes the nearest available crew.
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.
Work continues until the job meets our documented completion standard, verified before we call it done.
We don't cherry-pick which sewage cleanup jobs get reviewed — this is a representative cross-section.
