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.
We isolate the affected zone before starting any removal to limit cross-contamination.
Disposal documentation is provided as part of the job record.
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.
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.
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.
The truck that arrives is stocked specifically for Sewage Cleanup jobs, not a generic handyman setup.
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."
