How water treatment companies usually price
Water treatment companies test first, then quote the system installed. Service visits, filters and salt are sold as a plan or per visit.
Our guide on pricing water treatment work walks through it step by step, from your labor rate to the price on the estimate.
Where the ranges come from
5 of the 12 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: water softener installation cost calculator, radon mitigation 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: total hardness test kit; water test strips or a multi-parameter kit; tds meter; pipe cutters for copper and pex; pex crimp or expansion tool; adjustable wrenches and pipe wrenches; cordless drill and driver; hand truck with straps; buckets and a wet vacuum. The full tools list adds the pro kit and van stock, with maker prices where we could check them.
