Red Flags β€” When to Call a Second Plumber

  • βœ•Quotes a full sewer line replacement without first running a camera to diagnose the problem
  • βœ•Can't quote a flat or range price β€” charges "time and materials" with no estimate
  • βœ•Recommends hydro-jetting for a simple hair clog that a snake would clear for $150
  • βœ•No state plumbing license β€” most states require licensed plumbers for work beyond simple fixture swaps
  • βœ•Refuses to provide a written estimate before starting work
  • βœ•Doesn't pull a permit for water heater replacement or major pipe work (most jurisdictions require it)

Frequently Asked Questions

How do plumbers price their work β€” and how can I tell if I'm being overcharged?

Most plumbers use one of three models: flat-rate pricing (fixed price per job, you know the cost upfront), time-and-materials (hourly rate plus parts), or a hybrid. Flat-rate is generally better for the homeowner because there's no incentive to work slowly. For time-and-materials jobs, ask for a not-to-exceed cap. As a benchmark: a licensed plumber in most US markets charges $85–$150/hour for labor. Jobs over 3 hours should have a written estimate.

Should I repair or replace a water heater over 10 years old?

Tank water heaters last 8–12 years (gas) and 10–15 years (electric). If your unit is over 10 years old and needs a repair costing more than $300–$400, replacement is usually smarter β€” both for reliability and efficiency. New units are 15–25% more efficient. Tankless water heaters (which last 20+ years) cost more upfront ($1,500–$3,500 installed) but can save $80–$150/year in energy costs.

What causes recurring drain clogs β€” and is hydro-jetting worth it?

Recurring clogs are caused by three things: grease buildup (common in kitchen lines), root intrusion (common in sewer lines in older neighborhoods), or pipe scale/mineral deposits (hard-water markets). A camera inspection ($100–$300) identifies the cause. Snaking removes blockages but leaves the pipe walls coated. Hydro-jetting ($350–$900) scours the pipe walls clean and is worth the extra cost if the camera shows buildup, not just a one-time clog.

What plumbing work requires a permit?

Rules vary by jurisdiction, but these almost always require permits: new water heater installation, sewer line repair or replacement, adding new plumbing fixtures, re-piping significant sections, and water service line replacement. Simple repairs (faucet replacement, toilet flapper, drain cleaning) typically don't require permits. A contractor who skips required permits saves time but leaves you with unpermitted work that can complicate home sales and insurance claims.
