How plumbers usually price
Most service plumbers charge a trip or diagnostic fee and then a flat price per task from a price book. Bigger jobs get a written estimate with options.
Our guide on pricing plumbing work walks through it step by step, from your labor rate to the price on the estimate.
Where the ranges come from
11 of the 14 services carry a range. Each one comes from a koira.ai calculator that lists the cost guides behind it and the date they were checked: plumbing cost estimator, water heater replacement cost calculator. They are national figures; the calculators scale the labor share to your state's wages when you enter a ZIP.
Lines marked "Set your own" have no range we could source well enough to publish. Price them from your own hours and parts.
What it takes to deliver this menu
The starter kit behind these services: pipe wrenches in two or three sizes and adjustable wrenches; basin wrench and a faucet socket set; tubing cutters and a pvc or pex cutter; torch kit, flux, solder and a flame protector; pex crimp or expansion tool; hand auger and a closet auger; multimeter; step ladder; wet and dry vacuum; knee pads, gloves, eye protection and a respirator. The full tools list adds the pro kit and van stock, with maker prices where we could check them.
