Immediately stop running water, including washing machines, dishwashers, sinks, and showers. Do not pour caustic chemical drain cleaners into a completely blocked sewer line, as corrosive chemicals will sit in the pipes and present safety risks to servicing technicians.

Houston's subsoil consists primarily of expansive gumbo clay that swells significantly during wet periods and shrinks during summer droughts. This continuous ground movement places immense shear stress on underground sewer lines, leading to cracked joints, bellies, and root penetration from mature live oaks and pine trees.

In many cases, yes. Trenchless technologies such as cured-in-place pipe (CIPP) lining or pipe bursting allow technicians to rehabilitate damaged sewer lines through small access pits without digging continuous trenches through landscaping, driveways, or patios. Suitability depends on pipe structural integrity.

Ask whether the technician will perform a video camera inspection before and after work, whether they offer trenchless alternatives, what city permits are required, whether cleanouts will be installed, and what warranty terms apply to materials and labor.

Standard homeowners insurance policies typically exclude wear-and-tear or root intrusion on exterior sewer laterals unless an optional sewer/water line endorsement or utility line coverage was added to the policy. Check with your insurance carrier regarding your specific policy riders.
