A Clear Way Forward
Sewage Needs More Than a Mop and Bleach
Sewage carries bacteria and contaminants that soak into carpet, drywall and anything porous. Even after the water is gone, what’s left behind can make your home unsafe.
We remove the sewage, take out materials that can’t be safely cleaned, disinfect every surface, and dry the area completely. Then we rebuild it.

Sewage Backup? Do This First
- 1.Keep kids and pets away from the area.

- 3.Stop flushing and running water.
- 4.Turn off HVAC that serves the affected area only from a safe, dry location. Don’t enter contaminated water or touch wet electrical equipment to reach controls.
- 5.Call us at (248) 320-3245.
What’s Included
Complete Sewage and Biohazard Cleanup

Sewage Extraction
Contaminated water and waste removed with the right equipment and full protective gear. This is not a shop vac job.

Contaminated Material Removal
Carpet, pad, drywall and insulation that can’t be safely saved come out, get bagged and are disposed of properly.

Cleaning and Disinfection
Every affected surface cleaned and sanitized, not just wiped down. Looking clean and being safe are two different things.

Deodorizing
Odors treated at the source so the area smells normal again, not masked with fragrance.

Drying
The structure dried completely with moisture readings to confirm it, so mold doesn’t get a chance to start.

Restoration
Flooring, walls and finishes rebuilt so the space is safe and usable again, handled by the same team.
Step by Step
How Sewage Cleanup Works
Assess and Protect
We assess the affected area and set up protection to keep contamination from spreading. Our crew wears protective gear, and we explain which areas to avoid.
Extract Sewage
We remove contaminated water and waste with equipment suited to the job. We also identify whether the backup source needs a plumber before cleanup can continue.
Remove Contaminated Materials
Porous materials that can’t be safely cleaned are removed and disposed of properly. We explain what needs to go and document it for your claim.
Clean and Disinfect
We thoroughly clean affected surfaces before applying appropriate disinfectants. It takes more than wiping away visible waste to address the contamination.
Dry and Deodorize
We dry the remaining structure and check moisture readings before closing anything back up. Odor is treated at its source, not just covered with fragrance.
Rebuild
After cleanup and drying, we replace damaged flooring, walls and finishes. One team handles the work through the final repairs.
