Sewage & Biohazard Cleanup in Texas
Sewage backups, contaminated floodwater and other biohazards are Category 3 losses. They need protective equipment, removal of porous materials that were touched, cleaning and disinfection of everything else, and careful drying.

Houston's bayous, Hill Country rivers and the Gulf Coast flood during heavy rain and tropical storms.
In Fort Worth: Low areas near the Trinity River's forks and creeks such as Sycamore and Marine Creek see flash flooding during heavy spring storms. In Irving: Parts of Irving near the Elm Fork of the Trinity River are low-lying, and heavy rain can overwhelm local drainage. In Garland: Original cast-iron sewer lines in 1950s–70s homes are past their typical service life. Backups and under-slab leaks often trace back to them. In McKinney: Homes near McKinney's historic square often have century-old clay or cast-iron sewer laterals. Tree roots from mature pecans and oaks get into the joints and cause backups that come up through floor drains and tubs. A camera inspection of the line is worth doing after any backup.
Most homes are slab-on-grade with water lines and HVAC equipment in the attic, from post-war ranches to large master-planned communities.
Texas doesn't license general contractors statewide, but it licenses mold assessors and mold remediation contractors through the Texas Department of Licensing and Regulation (TDLR) for projects of 25 contiguous square feet or more.

Sewage & Biohazard Cleanup questions
Do I need a licensed mold company in Texas?
Yes, for jobs of 25 contiguous square feet or more. Texas requires a TDLR-licensed remediator, plus an independent licensed assessor to write the protocol.
Is a slab leak covered by insurance in Texas?
Many policies cover the water damage and the cost to access the pipe, but not the pipe repair itself. Your policy wording decides.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
