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.
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.
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.
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.
Carpet, pad, and drywall that contacted blackwater almost always require removal rather than drying in place.
Disinfection follows removal of unsalvageable materials, covering every remaining surface in the affected zone.
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.
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.
