Sealed work zones

Containment walls and HEPA filtration keep sewage odors and particles from spreading through the house.

Confirm license and insurance on arrival. Biohazard jobs should only go to properly insured pros.

Clear quotes before work

R

Removing Raw Sewage

Sewage is pumped and vacuumed out with equipment reserved for contaminated water, then disposed of properly.

P

Porous Material Removal

Anything porous that absorbed sewage, like carpet, drywall, and insulation, is removed and bagged.

D

Sanitizing Every Surface

Concrete, framing, and tile are cleaned and disinfected with EPA-registered products at the correct dwell time.

O

Deodorizing After Sewage

Air scrubbers and odor treatments clear the smell so it does not return once the area dries.

V

Confirming the Area Is Clean

Cleanliness is checked, sometimes with ATP swab testing, before drying gets the area ready for rebuild.

What Sewage Backup Callers Said

Our main line backed up into the basement. They sealed it off, suited up, removed everything contaminated, and the smell was completely gone.

Carmen E.Main line backup, basement

Honest about what had to be thrown away and why. I appreciated the explanation.

Steve R.Toilet overflow into finished room

With kids in the house, I wanted it contained. The plastic barrier and air scrubber kept it all downstairs.

Jenna P.Sewage backup, family home

FAQ

Sewage Cleanup Questions Answered

It is Category 3, meaning grossly contaminated. That category triggers full biohazard protocols.

Small, contained jobs may be fine. For large backups or vulnerable family members, staying elsewhere is often safer.

A very small hard-surface spill can be cleaned with gloves, boots, and a disinfectant. If sewage reached carpet, drywall, or a large area, professional cleanup is the safer choice.

Many standard policies exclude sewer backup unless you have a specific sewer or drain backup endorsement. Check your policy with your agent.

Tree roots, grease clogs, damaged pipes, and city sewer overloads are the usual culprits.

No. A Water Damage is a free referral service connecting you with independent, licensed and insured local contractors who do the work and bill you directly.
