Frequently Asked Questions
Why does black water cost so much more to clean?
Category 3 water requires biohazard PPE, HEPA containment, antimicrobial treatment, hazardous waste disposal, and removal of porous materials that cannot be decontaminated. Labor and disposal costs are 2–4x Category 1.
Can Category 1 water become Category 3?
Yes. Category 1 water left untreated for 48–72 hours absorbs organic material and bacteria, escalating to Category 2 or 3. Fast professional response keeps costs at Category 1 levels.
Does insurance pay more for Category 3 cleanup?
If covered (sudden sewage backup with endorsement, or internal pipe burst), insurance pays for appropriate Category 3 protocols. Flood water from rivers requires separate flood insurance.
