How is sewage cleaned up in a crawlspace?
Crawlspace sewage cleanup involves repairing the leak first, then removing contaminated insulation and vapor barrier, removing or treating affected soil and gravel, cleaning and disinfecting joists, subfloor and foundation surfaces, drying the space, and installing a fresh vapor barrier when appropriate. The goal is to remove the contamination and the odor source.
The hidden sewage problem
Many Nashville houses are built over crawlspaces, and the drain lines run right through them. Cracked cast iron, separated joints and failed connections can leak wastewater onto the ground for a long time. The first sign is often an odor in the house, flies, or insulation hanging from the joists.
Crawlspace work is tight, dirty and hazardous. Our crews have the equipment and protection to work in confined spaces, remove contaminated materials and treat the framing so the odor does not come back.
Signs of sewage in the crawlspace
- Sewage odor in rooms above
- Flies near vents or the access door
- Wet or sagging insulation
- Damp soil or standing water under the house
- Rising humidity or musty smell
- A leak found during a plumbing inspection
Why crawlspace sewage is serious
The crawlspace connects to the air you breathe.
Air quality
Air from the crawlspace moves up into the living space.
Wood damage
Moisture and waste can weaken joists and subfloor.
Mold
Humidity plus organic material is ideal for mold.
Pests
Sewage attracts insects and rodents.

Crawlspace sewage cleanup in Nashville
Older neighborhoods across Nashville often have original cast iron drain lines under the house. As they age, they crack and separate, and the leak goes straight into the crawlspace.
Masking the smell does not work. The contaminated materials have to come out, and the framing has to be cleaned and dried. After cleanup, our sewage odor removal services can address any remaining odor in the home.
If framing or subfloor is damaged, see subfloor and structural remediation.
