Plumbing questions, answered
How much does a plumber cost in San Antonio?
Service calls run $75–$150. Drain clearing is $100–$300, toilet/faucet repairs $100–$400, water heater repair $150–$500. Bigger jobs: water heater replacement $1,200–$2,500, repiping $4,000–$15,000, sewer line $3,000–$8,000.
What is a slab leak and why is it common in San Antonio?
Most SA homes sit on concrete slabs over expansive clay soil that shifts with wet/dry cycles — stressing water lines under the foundation. Signs: warm floor spots, hissing water sounds, unexplained high water bills, or cracks. Detection runs $150–$400; repairs $1,500–$4,000+ depending on access.
How long does a water heater last in San Antonio?
SA's water is very hard (~15–20 grains) — sediment buildup kills tanks faster than the national average. Expect 8–10 years instead of 12, shorter without annual flushing. A licensed flush runs $100–$200 and extends tank life.
Is a running toilet or dripping faucet worth a service call?
A running toilet can waste 200+ gallons a day — it shows up on your SAWS bill. The fix is usually a $100–$250 flapper/fill-valve job, cheaper than ignoring it for a billing cycle.
Do plumbers charge extra for emergencies?
After-hours, weekend, and holiday calls typically add $50–$150 or a higher dispatch fee. A true emergency (burst line, sewage backup, gas smell — call 911 first for gas) is worth it; a slow drip usually isn't.
What should I do if a pipe freezes or bursts in San Antonio?
Shut off the main water valve first — on most SA homes it is at the meter box near the curb or where the line enters the house. Open faucets to drain pressure, then call a plumber. Freeze bursts here usually show up as slab leaks or attic line failures within a day of thawing, so even a self-repaired line is worth a pressure check after a hard freeze.
