Plumbing in Houston: what to know
Houston is hot and humid for most of the year, with heavy rain events and hurricane risk from June through November. Many homes sit on slab foundations over expansive clay soil, which shrinks in drought and swells in rain.
- Heavy rain can overload sewer lines and cause backups; a backwater valve can help.
- After a storm, check for sewer backups and damaged outdoor lines before running water heavily.
- Shifting clay soil can crack slab plumbing and sewer lines, so unexplained high water bills deserve a leak check.
How much does plumbing cost?
- Plumber (per hour): $70 – $150
- Burst pipe repair: $190 – $970
- Main sewer line unclog: $340 – $630
