Sewage Cleanup in Denver, CO
Two things matter when you call a sewage cleanup: how fast they show up, and whether they fix it the first time. We try hard at both. We carry our own insurance, pull our own permits, and service everything we install. Same shop, all the way through.
What you're paying for
Sewage cleanup is regulated as Category 3 (black water) work under IICRC S500. That means biohazard PPE — Tyvek suits, respirators, full eye protection — for the crew, plus containment-zone protocol around the affected area.
Porous materials in direct contact with sewage cannot be effectively decontaminated. Carpet, padding, drywall to 12 inches above the line, baseboards, and unfinished wood typically require removal and disposal as biohazard waste.
Hard surfaces are sanitized with EPA-registered antimicrobials. Air scrubbers with HEPA and activated-carbon filters run during the work to control airborne pathogens and odor.
Documentation is critical. Insurance adjusters reject sewage claims that don't show category determination, S500 protocol followed, and EPA-product use logs.
