Sewage backup cleanup in Texas
Sewage cleanup treats the water as Category 3 (grossly contaminated): crews in protective gear remove it, discard porous materials it touched, clean and disinfect hard surfaces, and dry the structure. Don't try to clean sewage with household products and a mop.

Sewage backup cleanup in Texas: local conditions

Call with your ZIP to confirm a company serves your address.
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. In Houston: Decades of groundwater pumping caused subsidence across the Houston area. Combined with shifting clay, that movement cracks older cast-iron and clay sewer lines under slab homes, which leads to backups and slow under-slab leaks. In Sugar Land: Levee systems protect much of Sugar Land, but extreme river levels, as in 2016 and 2017, and local drainage backups still cause flooding concerns.
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 backup 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.
Does homeowners insurance cover sewage backup?
Often only with a water or sewer backup endorsement, which most insurers offer as an add-on. Check your declarations page.
Is sewage cleanup dangerous?
Yes. Sewage contains bacteria, viruses and parasites. Professional crews use protective equipment and disinfectants for this reason.
