Cast Iron Pipes in Older Houston Homes
If your Houston home was built before the 1980s, especially inside the Loop, there is a good chance your drains are cast iron. That pipe does not last forever, and clay-soil movement speeds up the end.
How cast iron fails
Cast iron corrodes from the inside out, scaling shut and growing rough enough to catch everything that passes. Outside, soil movement cracks it and roots work into the cracks.
The result is recurring backups that no amount of snaking truly fixes, because the pipe itself is the problem.
Signs it is time
Repeated main-line clogs, sewage smells, slow drains throughout the house at once, and patches of unusually lush grass over the sewer line all point to a failing line.
A camera inspection settles it: you can see the scaling, cracks and root intrusion on screen.
Replacement options
Depending on the line, options range from a targeted spot repair to a trenchless replacement that pulls new pipe through the old path with minimal digging.
A good plumber walks you through what the camera shows and recommends the least invasive fix that actually solves it.
