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.
Three-story townhomes put laundry and bathrooms above living space, so a single leak can run down through two floors. Older homes in the Heights are often pier-and-beam, where water collects in the crawlspace. Slab ranches near the bayous have the highest flood exposure.

Other risks in Houston
Bayou and street flooding
Brays, White Oak, Buffalo and Greens Bayous overflow in major storms, and flat streets flood in heavy rain even outside mapped floodplains. Hurricane Harvey in 2017 flooded neighborhoods across the city.
Humidity and mold
High year-round humidity means wet materials grow mold quickly, and sweating AC ducts cause mold even without leaks.
Hurricane season
From June through November, tropical systems bring wind-driven rain, roof damage and power outages that leave homes without AC to control humidity.
Signs you need sewage backup cleanup
- Water coming up from floor drains, tubs or toilets
- Gurgling drains
- Sewage odor in the house
How the work is done
Protect, then Remove, then Disinfect, then Dry. See the full sewage backup cleanup process.
What affects the cost
Prices depend on the job, so restoration companies in Houston quote after an assessment. The main drivers are how much area is affected, how long it stayed wet, and what has to be removed or rebuilt. See the full list of sewage backup cleanup cost factors.
Sewage backup cleanup questions
Do I need a permit to repair water damage in Houston?
Cleanup and drying don't. Rebuild work involving plumbing, electrical or structure requires a City of Houston permit, and substantially damaged homes in the floodplain may face elevation requirements.
How fast does mold grow after a leak in Houston?
In Houston's humidity, mold can begin growing on wet drywall and wood within 24–48 hours, which is why drying should start the same day if possible.
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.
