Sewage Cleanup Services for Houston, TX Homes and Businesses
Sewage cleanup is the removal of raw sewage and everything it soaked into, followed by cleaning and disinfection of the affected area. Because sewage carries bacteria and viruses, it is handled as a biohazard.

With a Very High river flood risk rating from FEMA for Harris County, flood events here can mix floodwater with sewage, which is treated as Category 3 contamination. About 47% of homes in Houston were built before 1980, and older clay or cast iron sewer pipes crack and clog with roots over time.

- Cleaning and sanitizing of salvageable furniture, appliances and stored belongings

Sewer Backup Questions Answered for Houston, TX
How long does sewage cleanup take?
Small jobs may be finished in a day, while larger ones with tear-out, drying and odor treatment take longer. The time depends on the area affected and what had to be removed. The crew can tell you what to expect after assessing the space.
How do I clean up a sewer backup?
Keep people and pets out, turn off power if water is near outlets, and avoid touching the sewage. Safe cleanup needs protective gear, extraction, removal of soaked materials and disinfection. For anything more than a small spill, a cleanup company is the safer choice.
Does homeowners insurance cover sewage backup?
Often only with an added endorsement. Many standard policies treat sewer or drain backup separately from sudden water damage. Call your insurer before cleanup begins, take photos and keep receipts, and ask what they need to see.
Why does drywall have to be removed after sewage?
Drywall is porous and holds contamination that can spread germs and odor long after the surface looks clean. Crews usually cut out wall board that sewage touched, and often take out a margin above the wet mark to reach clean material.
How long does it take to get sick from raw sewage?
Symptoms such as stomach cramps, vomiting and diarrhea can start within hours or take a few days. Anyone with symptoms after exposure should contact a doctor. Children, older adults and people with weak immune systems are at higher risk.
Can a sewage cleanup service work at night or on weekends?
Yes. Sewage backups do not wait for business hours, so you can call Houston Biohazard Cleanup Help any time, 24/7. Describe what happened and you get the next safe step explained.
