Estimated cost
$300

Plumber hourly rates in 2026 average $85-$155 nationally, with emergency after-hours calls at $175-$300 per hour plus trip charges. Most plumbers also charge flat-rate book pricing for common jobs — swapping a toilet is $200-$450, installing a water heater $1,500-$4,000, and running a new gas line $600-$1,800 for a typical range.

Whole-house re-pipe — when and why

If your home has polybutylene (PB pipe), galvanized steel, or failing copper from 1970s-80s aggressive water territories, re-piping is inevitable. 2026 pricing: PEX re-pipe $4,000-$9,000 for a typical 1,500 sq ft home, copper re-pipe $8,000-$15,000 for the same house. PEX is now accepted in virtually every jurisdiction and outperforms copper in freeze resistance, water quality, and install speed. Don't let anyone talk you into copper unless local water chemistry genuinely requires it.

Water heater replacement — tank vs tankless

Standard 40-50 gallon tank water heater: $1,500-$2,800 installed in 2026. Heat pump water heater: $2,800-$4,500 installed (qualifies for 30% federal 25C credit up to $2,000). Tankless gas water heater: $3,500-$6,500 installed with potentially new gas line and venting. Heat pump water heaters have the fastest payback at 4-7 years in most markets because of the federal credit plus electricity vs gas cost math.

Plumber vetting

Verify: state plumbing license (separate from general contractor license in all 50 states), master plumber on staff for anything beyond fixture swaps, $1M general liability and workers comp, and upfront flat-rate pricing on common jobs. Avoid any plumber who won't provide written estimates before starting work, who requires cash payment, or who says permits aren't needed for work that clearly requires them (water heater replacement, gas line work, re-pipes).

Frequently asked questions

What does a plumber cost per hour in 2026?
National average $85-$155/hour for standard hours, $175-$300 for emergency after-hours calls. Most plumbers also use flat-rate 'book pricing' for common jobs — usually cheaper than hourly for standard installs. Expect a $60-$150 trip/dispatch charge on most service calls regardless of job duration.
Do I need a permit to replace a water heater?
Yes in virtually all jurisdictions. Permit costs $75-$200 and requires inspection. Unpermitted water heater installs are the #1 cause of insurance claim denials after water heater leaks and flood damage — the insurance company uses the missing permit to deny coverage.
How long does a whole-house re-pipe take?
2-4 days for a typical 1,500-2,500 sq ft home in PEX, 4-7 days in copper. Work involves cutting access holes in drywall at every fixture — budget $1,500-$4,000 in drywall repair on top of plumbing cost. Water service interruption is usually limited to 4-8 hours total across the project.
When should I call an emergency plumber vs waiting?
Call emergency: active flooding, sewer backup into house, complete loss of water service, natural gas smell. Wait for regular hours: slow drains that still work, minor drips that aren't causing damage, running toilets, low water pressure. Emergency calls run 2-3x regular rates; wait for business hours when safe.
How long do plumbing fixtures last?
Toilets: 15-25 years (replace when flush mechanism repeatedly fails). Faucets: 10-20 years for quality brands (Moen, Kohler, Delta); 3-8 years for big-box cheap brands. Garbage disposals: 8-15 years. Water heaters: tank 8-12 years, tankless 20+ years, heat pump 13-15 years. Supply lines to fixtures: 5-10 years for braided stainless; replace during any fixture work.
