Well Drilling Cost in 2026
Water well drilling costs $3,000 to $15,000 or more for a complete residential system, with most projects averaging $5,500 to $9,000. The cost to drill a well is priced per foot — $25 to $85 depending on rock type — and your local water table, not you, sets the footage.
Depth is the number that moves the estimate most, followed by geology: sand and gravel drill cheaply, granite and hard crystalline rock drill slowly and cost the most. The pump, pressure tank, casing, and county permit round out the full-system total.
Well Drilling Pros connects you with licensed local drillers who check nearby well logs before quoting per foot. The ranges below are honest 2026 national figures from Angi, HomeGuide, and HomeAdvisor — treat them as a planning number and insist on a written per-foot quote.
Typical national range
$3,000 – $15,000
Complete systems average $5,500–$9,000. Deep hard-rock wells in New England and the Rockies run well past this.

Cost breakdown
| Item | Typical range | Notes |
|---|---|---|
| Drilling & casing — sand / gravel | $25 – $40 | Per foot. Soft soil is the fastest, cheapest formation to drill. |
| Drilling & casing — sedimentary rock | $35 – $55 | Per foot. Limestone, sandstone, and shale. |
| Drilling & casing — granite / crystalline rock | $55 – $85 | Per foot. Hard rock is the slowest, most expensive to drill. |
| Well pump, installed | $1,000 – $2,500 | Submersible for most drilled wells; sized to depth and household demand. |
| Pressure tank, installed | $400 – $1,500 | Stores pressurized water so the pump isn't running constantly. |
| Well permit (varies by county) | $100 – $500 | Usually pulled by the driller and itemized on the quote. |
What changes the price
Providers quote their own work — these are the factors that consistently move the number.
- Depth: the single biggest cost driver, set by your local water table — the national average is about 150 ft, but New England and Rocky Mountain wells commonly run 300–800 ft.
- Geology: drilling runs $25–$40/ft through sand and gravel, $35–$55/ft through sedimentary rock, and $55–$85/ft through granite and crystalline rock.
- Casing and grouting: unstable formations need extra casing beyond the standard footage, billed on top of the per-foot rate.
- Pump and pressure tank: a complete system adds $1,000–$2,500 for the installed pump and $400–$1,500 for the pressure tank if you're not reusing equipment.
- Well use: irrigation and livestock wells are priced the same per foot but higher flow demands can mean a larger pump or larger-diameter bore.
- County permits and access: permits run $100–$500 by jurisdiction, and remote or hard-to-reach drill sites add mobilization cost.
How location changes the number
Regional depth norms drive most of the price spread: Gulf Coast wells (Louisiana, Mississippi) often finish at 85–100 ft, the Midwest and Southeast at 200–400 ft, and New England and the Rockies at 300–800 ft.
State anchors show the extremes: Mississippi's shallow water tables make it the cheapest state for a complete well (around $6,200), while deep hard-rock states like Hawaii, New Hampshire, Maine, and Massachusetts can run $32,000–$38,500.
Frequently Asked Questions
How much does it cost to drill a well?
Most complete residential well systems cost $5,500–$9,000, with a full range of $3,000 to $15,000+. Drilling itself runs $25–$85 per foot depending on geology, plus $1,000–$2,500 for an installed pump, $400–$1,500 for a pressure tank, and $100–$500 for the permit.
How much does it cost to drill a well per foot?
Roughly $25–$40 per foot through sand and gravel, $35–$55 through sedimentary rock like limestone or shale, and $55–$85 through granite. Quotes usually cover drilling plus standard casing per foot; extra casing through unstable formations is billed separately.
How deep does a well need to be?
Whatever depth reaches a reliable aquifer under your property — the national average is around 150 ft, but Gulf Coast wells often finish at 85–100 ft while New England and Rocky Mountain wells commonly run 300–800 ft. Local drillers estimate from nearby well logs before drilling.
Does the drilling quote include the pump and pressure tank?
Often not — many drillers quote the borehole, casing, and grouting per foot and price the pump system separately. Ask for a complete-system quote so you can compare apples to apples: pump ($1,000–$2,500 installed), pressure tank ($400–$1,500), trenching, and the permit.
How much does a well inspection cost?
A well inspection runs about $250–$550 and is worth ordering before buying a home on a well — it covers water quality testing, flow rate, and the condition of the pump and pressure system, so you know what you're inheriting before closing.
