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.

The decision to remove a material rather than dry it in place isn't a cost-cutting call on a sewage job — it's a safety standard, since porous materials that contact blackwater can't be fully sanitized no matter how long you dry them.
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.
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.
We isolate the affected zone before starting any removal to limit cross-contamination.
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.
Final verification includes both moisture and contamination checks before sign-off.
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.
Crews staged locally get to your address quickly, equipment already loaded for Sewage Cleanup work.
You approve the number before equipment turns on — no surprise invoice after the fact.
Work continues until the job meets our documented completion standard, verified before we call it done.
