How do you find water well drillers near you?

  1. Start with your state's licensing agency. Most states license or register water well contractors. NGWA (Wellowner.org): Licensing Several publish searchable lists: Pennsylvania's licensed driller database can be searched by county served and service type, Pennsylvania DCNR: Licensed Water Well Drillers New York's DEC offers a registered water well contractor search, NYSDEC: Water Well Contractor Program and Ohio publishes lists of registered private water systems contractors. Ohio Department of Health: Information for Private Water Systems Contractors Water well permits by state lists the agencies we have checked.
  2. Ask your county health department. Where it issues well permits, it knows which contractors work locally.
  3. Check nearby well reports. State well records name the driller of each well, which shows who has actually drilled near you; see how to find water well logs.
  4. Use an independent membership lookup. NGWA's contractor lookup lists member professionals; NGWA does not endorse or guarantee them, and membership is not a license.

What services do water well drillers offer?

Service When you need it — comparison worksheet
ServiceWhen you need it
Well drillingA new well or a replacement well
Well deepeningAn existing well with a falling water level or too little storage
Pump installation and controlsNew wells, failed pumps, pressure problems
Well rehabilitationDeclining yield from clogging or encrustation
Water treatment and disinfectionPositive bacteria tests or water-quality problems
Well inspection and testingHome purchases, annual checkups
Well abandonment and sealingRetiring an unused or replaced well

Not every company does all of these. Some drill only; others focus on pumps and service. Ask what they do in-house and what they subcontract.

How do you choose a well driller near you?

Get written, itemized quotes from more than one contractor and compare them line by line. Check each license with the issuing agency, ask for proof of liability and workers' compensation insurance, and ask for references from nearby jobs. NGWA (Wellowner.org): How to Hire a Water Well Contractor Agree a maximum depth and what happens if the hole is dry before signing. The vetting questions, quote checklist and cost calculator walk through each step, and who pays for a dry hole covers the contract terms that matter most. [NGWA-HIRE source note]

Red flags when hiring

  • A single lump-sum price with no itemized lines or exclusions
  • No written contract, or no maximum depth
  • A promise of water at a specific depth or yield
  • Unwilling to share a license number you can check with the state
  • No mention of who files the permit and the well report

Questions to ask when you call

When you contact well drilling companies near you, ask the same questions of each so the answers are comparable:

  1. Are you licensed or registered for water well work in this state, and under what number?
  2. How many wells have you drilled near this property, and how deep were they?
  3. What depth and yield do you expect, and what is that based on?
  4. What casing, grout and well cap will you use?
  5. How will you test the well's yield, and will I get a written report?
  6. Who files the permit or notice and the well report?
  7. What is the most you will drill without my written approval, and what do I owe if the well is dry?
  8. Do you install the pump, pressure tank and water line, or does someone else?

Write the answers down; the quote checklist has space for two offers side by side.

Well drillers vs. pump and well service companies

Drilling contractors build new wells and deepen existing ones. Pump and well service companies focus on existing systems: replacing pumps, pressure tanks and controls, diagnosing low pressure, and disinfecting wells. Many companies do both. If your existing well has lost water, a service visit to check the pump and controls usually comes before any drilling, since a failed pump is the most common cause of losing water.

How listings on this directory work

Listings preserve the supplied source observations, including distinct licence holders, business records, registrations, employer locations and certificate observations. Available names, licence numbers, work details and contacts are shown; missing fields remain missing. Texas retains TDLR endorsements and expiry dates. Other sources identify their supplied roster edition when known and the date the directory file was received, which is not a fresh agency verification. A county describes a recorded address, not a service area. Shared names or phones do not merge different licences or establish a company affiliation. Nothing is paid for placement. See how listings work for the source details, and what affects well drilling cost before you call.

Common questions

How do I find a reputable well driller near me?

Start with your state's licensing agency, ask your county health department, and look at who drilled nearby wells in state well reports. Then compare written quotes, check licenses and insurance, and ask for local references.

Are well drillers licensed?

In most states, yes. Licensing or registration is usually handled by a state department of natural resources, environment or health. Not every state requires it, so check with your state.

What questions should I ask a well driller?

Ask about their license, insurance, local experience, expected depth, method, casing and grouting, how they test yield, the maximum depth they'll drill without your approval, and what happens if the well is dry.

Do well drillers also install pumps?

Many do, but not all. Some states license pump installers separately from drillers. Ask whether the pump, pressure tank and water line are included in the quote.
