These are typical or estimated ranges, not quotes. Prices for your well can be higher or lower.
What moves the price
- How deep the well is and how deep the pump sits. See typical depths by town.
- Pump size, and how much pipe and wire the job needs.
- Code updates found during the job, such as a short casing, a buried cap or an old well pit.
- Work past the pressure tank. House plumbing and water softeners are separate jobs for a licensed plumber.
Help paying
- Some owners qualify for state grants or USDA loans. See grants and help.
- Homeowners insurance usually excludes wear and tear. Lightning or fire damage may be covered, and some policies offer an equipment breakdown add-on. Check your policy.
Getting an estimate
- Ask for a written estimate from a DNR-licensed pump installer or well driller.
- Wisconsin requires licensed contractors to show their license number on estimates and invoices.
- Ask what is included: parts, labor, disposal and a bacteria test after the work.
When you need a licensed professional
- Pump, pressure tank and pressure switch work.
- Drilling, deepening, or filling and sealing a well.
- Wisconsin rules require a DNR-licensed pump installer for pump and pressure-tank work on a drinking-water well; check with DNR if you’re unsure.
