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.
Every sewage job follows documented contamination standards, not an improvised cleanup approach.
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.
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.
Porous materials can't be fully sanitized after blackwater contact, which is a safety call, not a cost-cutting one.
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.
This is the same sequence every sewage cleanup job follows, regardless of size.
A real person answers, asks a few fast questions, and routes the nearest available crew.
Crews staged locally get to your address quickly, equipment already loaded for Sewage Cleanup work.
A technician assesses the scope on-site and provides a written flat-rate quote before any work begins.
We stand behind the result with a documented sign-off, not just a verbal assurance.
