Cat-3 black water · live dispatch

Detroit sewer backup cleanup — stop the source, contain the contamination, document for insurance

A sewer backup is not a "flood." It's Category 3 black water — raw waste, pathogens, and groundwater mixed. The cleanup protocol is different than a clean-water leak. Detroit Drain Pros arrives PPE-equipped, clears the source line, zones the contamination, and documents everything your insurance carrier will ask for.

IICRC water categories

Not all backup water is the same. Cleanup depends on which category.

The IICRC (cleaning industry standard) classifies water-damage events into three categories. Sewer backups are Category 3 — the most contaminated, with a specific PPE and disposal protocol.

Category 3 · Black Water DANGER

Sewer backup

Wastewater from the sewer line, basement floor drain overflow, toilet backup with sewage. Contains pathogens, bacteria, organic matter, possible chemicals.

Full Tyvek + N95 + chemical-resistant gloves
Affected porous materials (carpet, drywall) discarded
Hard surfaces sanitized with EPA-registered biocide
Drying equipment + dehumidifiers for 48-72 hours
Documentation for homeowner's insurance claim
Air-quality re-test before closure

Category 2 · Gray Water CAUTION

Dishwasher / washing-machine overflow

Used water with detergents, food particles, or laundry residue. No raw sewage, but still contaminated enough to make people sick if left untreated.

Gloves + light PPE
Carpet may be salvaged with extraction + sanitization
Drywall checked, replaced if saturated
Drying within 48 hours to prevent mold
Mild biocide on hard surfaces
Documented but lower insurance involvement

Category 1 · Clean Water SAFE

Supply-line leak

Broken supply pipe, water-heater leak, refrigerator-line leak. No contamination at the source — but becomes Category 2 within 48 hours if left untreated.

Standard gloves only
Most materials salvageable with prompt drying
Extraction + air movers
No biocide required
Drywall checked but rarely replaced
Standard homeowner's coverage applies

Cat-3 response protocol

Five things that happen the moment we arrive at a Detroit backup

Sewer backup cleanup isn't just "wet vac the floor." There's a specific sequence that protects your health, your home, and your insurance claim.

Stop the source

Clear the blocked line first. If the line still restricts, every wet vac just adds more contamination.

Zone the area

Mark contaminated boundary. Plastic sheeting on doorways. No foot traffic in/out without changing PPE.

Document everything

Photos before extraction. Affected items listed. Water-line measurements. Insurance file built as we work.

Extract + sanitize

Wet vac through HEPA filtration. EPA-registered biocide on hard surfaces. Porous materials bagged for disposal.

Dry + verify

Air movers + dehumidifiers for 48-72 hrs. Moisture meter check. We don't close until readings are dry.

Insurance documentation

Most Detroit homeowner policies include or can endorse sewer backup coverage. We build the documentation file your carrier will ask for — before they ask.

Time-stamped photos at arrival and during work
Cause-of-loss statement (technical, signed)
Itemized list of damaged property
Square footage of affected area
Moisture-meter readings before and after drying
Disposal manifest for discarded materials

Prevent the next one Backwater valve

If you've had one Detroit sewer backup, you'll likely have another — especially in Downriver and basement-finish homes. A backwater valve closes automatically when sewer water tries to flow backward into your line.

One-time install $895-$1,495 flat rate
Sits in the basement floor or cleanout line
Passive operation — no electricity
Often partially insurance-reimbursed after a claim
City permits handled by us
10-year mechanical warranty
