How to Hire a Licensed Well Driller

What to check, what to ask, and the red flags that should make you keep looking, before you sign anything.

Check Licensing Requirements Where You Live

Licensing rules for water well contractors are set state by state, and they vary widely. A peer-reviewed 2019 study in the journal Water Policy found that all 50 states have some form of legal requirement covering the drilling or construction of new wells, but beyond that baseline, states differ dramatically in how comprehensive their rules are, some regulate licensing, bonding, and construction standards closely, others leave much more to the individual contractor. Some states also incorporate exam content from the National Ground Water Association (NGWA) into their own licensing process; NGWA reports that 14 states and two counties do this as of its most recent count.

Because there is no single national standard, the most reliable way to check requirements for your state is to look up your state's water resources agency, environmental agency, or well-construction board directly, they are the licensing authority, not any private directory. Our well drilling license requirements by state table links straight to each state's official licensing board and shows whether a license is required and who issues the permit. You can also browse this site's state-by-state pages to see the contractors listed for your area.

Ask the Right Questions Before Hiring

A few questions can save you from a bad outcome later:

• How many years have you been drilling wells in this specific area, and do you know the local geology?
• Can you provide references from recent jobs nearby, ideally ones with similar depth or ground conditions?
• What happens to the price if you hit rock or have to drill deeper than expected? Get the answer in writing.
• What's included in the quote, drilling, casing, pump, pressure tank, testing, or are some of those separate?
• Who pulls the permit, and who is responsible for well abandonment or plugging if the well fails?
• What warranty do you offer on the well and the pump system?

Get Multiple Quotes

Get at least two or three quotes from different licensed contractors before deciding. Make sure each quote itemizes the same components (drilling, casing, pump, tank, testing) so you're comparing like for like rather than one contractor's all-in price against another's drilling-only estimate. See our well drilling cost guide for what each of those components typically costs, so you can spot a quote that looks unusually high or suspiciously low.

Confirm Insurance and Bonding

Ask for proof of general liability insurance and, where your state requires it, a contractor's bond, then verify the certificate is current rather than just taking the contractor's word for it. Insurance protects you if equipment damages your property during drilling; bonding gives you a path to recovery if the contractor fails to complete the work or violates licensing rules. If a contractor is reluctant to provide documentation, that's a reason to keep looking.

Watch for Red Flags

• Refuses to provide a license number or asks you to skip the permit process.
• Demands full payment up front before any work begins.
• Won't put the scope of work, price, and timeline in writing.
• Has no fixed business address or can't provide local references.
• Pressures you to sign the same day, or quotes a price far below every other bid without explanation.

Review the Contract Before You Sign

A solid well-drilling contract should spell out the scope of work (depth range, casing type and diameter, pump specifications), who is responsible for permits, the payment schedule, an estimated timeline, and what warranty applies to the well and equipment. If the contract is vague on any of these, ask for it to be spelled out before you sign, not after drilling starts.
