Well Drilling Cost Per Foot (2026)

Drilling a well is one of the largest single expenses a rural homeowner faces, and the per-foot price is the number every contractor quotes first. The average well drilling cost per foot in 2026 runs $25 to $65 per foot, with most residential wells landing between $35 and $55 per foot for a complete drilled and cased well. That means a typical 200-foot well costs $7,000 to $13,000 for drilling and casing alone, before the pump, pressure tank, and electrical work. Depth, geology, and location swing the total by thousands of dollars, so this guide explains what the per-foot rate actually includes, what it leaves out, and how to get a quote you can trust.

Average Well Drilling Cost Per Foot in 2026

The per-foot rate quoted by most drillers covers the drilling itself, the steel or PVC casing that lines the borehole, and basic grouting to seal the casing. In soft ground such as sand, gravel, and clay, rates run $25 to $45 per foot. In hard rock such as granite or basalt, rates climb to $50 to $65 per foot or higher, because drilling is slower and wears out bits faster. Some contractors quote a lower per-foot rate but charge separately for casing, which can add $15 to $30 per foot, so the headline rate can be misleading. A complete per-foot price, including casing and grouting, is the only number worth comparing between bids. Regional differences are significant. Areas with deep water tables, such as parts of the West, see higher total bills simply because wells run deeper. Areas with shallow water and soft soils, such as parts of the Southeast and Midwest, see lower totals. Permit fees also vary by state and county, from under $100 to over $1,000. When comparing quotes, ask each driller to state the per-foot rate, the casing material and diameter, and exactly what is included, in writing.

Total Well Drilling Cost by Depth

Depth is the multiplier that turns a per-foot rate into a total bill. The table below shows typical total drilling and casing costs at the average $35 to $55 per foot range, before pump and tank costs.

These totals cover drilling and casing only. The complete well system, including the pump, pressure tank, wiring, and piping into the home, typically adds $2,500 to $5,000. Our well pump installation cost guide breaks down that portion in detail. Also note that drillers cannot guarantee depth in advance. The well goes as deep as the water requires, so most contracts price by the foot actually drilled, with an estimated total and a cap you agree on beforehand.

What Affects the Per-Foot Price

Geology is the biggest variable. Soft sedimentary ground drills quickly with standard rotary equipment, while hard rock requires air rotary or cable tool methods and frequent bit changes, which slow the job and raise the rate. Depth itself raises the per-foot rate on very deep wells, because the crew must handle longer drill strings and more casing. Casing diameter matters too. A 6-inch residential well is standard, but larger diameters for high-yield wells cost more per foot in both material and labor. Site access affects price as well. A drilling rig is a large truck, and if it cannot reach the well location easily, the crew may need to clear a path, bring in a smaller rig at a premium, or use a crane, all of which add cost. Water quality requirements also play a role. Some states require grouting the full casing length to protect aquifers, while others require only a surface seal. Full-length grouting adds material and time. Finally, the local market matters. In areas with many licensed drillers, competition keeps rates near the low end. In remote areas with one or two drillers, rates trend higher, and scheduling may take weeks or months.

Drilling Methods Compared

Three drilling methods dominate residential work, and the method your driller uses affects both price and timeline. Rotary drilling is the most common. A rotating bit grinds through soil and rock while drilling fluid carries cuttings to the surface. Rotary rigs handle most geology, drill 100 to 200 feet per day in favorable ground, and cost $25 to $55 per foot for typical residential wells. Air rotary drilling uses compressed air instead of fluid and is preferred in hard rock, where it drills faster and keeps the borehole cleaner. Air rotary rates run $40 to $65 per foot in rock. Cable tool drilling, also called percussion drilling, repeatedly drops a heavy bit to crush rock. It is slower, often 20 to 50 feet per day, but it works well in certain fractured rock formations and can produce less disturbance to the aquifer. Cable tool rates vary widely, $30 to $60 per foot, and the method is less common today. Your driller will choose the method based on local geology and experience, not on your preference, but it is worth asking which method they plan to use and why. A driller experienced in your local geology is worth more than a slightly lower per-foot rate from someone unfamiliar with the area.

Costs Beyond the Drilling Itself

The per-foot rate is only part of the bill. Permits and inspections typically cost $100 to $1,000 depending on jurisdiction, and some counties require a licensed driller to file a well completion report with the state. Water testing after drilling costs $100 to $400 for a standard panel covering bacteria, nitrates, and minerals, and more if you test for arsenic, radon, or other regional contaminants. A well cap, pitless adapter, and electrical hookup are sometimes included in the pump installation rather than the drilling contract, so confirm who provides them. If the well produces sediment or low yield, additional work such as well development, hydrofracturing, or a deeper re-drill can add $1,000 to $5,000. In dry areas, a low-yield well may also need a storage tank and booster system, adding $1,500 to $4,000. Trenching from the wellhead to the house, if not included in the pump installation, runs $10 to $25 per foot. The safest approach is to ask for a total project estimate that lists drilling, casing, grouting, permits, testing, pump, tank, and electrical work as separate lines, so there are no surprises when the final invoice arrives.

How to Get an Accurate Drilling Quote

A reliable quote starts with local knowledge. Ask neighbors with wells how deep their wells are and what they paid, since wells in the same area usually hit water at similar depths. Check with your state water agency or county health department for well logs from nearby properties, which list depth, yield, and geology. These records are often free and give drillers a much better basis for an estimate. Get at least three written quotes, and make sure each one states the per-foot rate, casing material and diameter, grouting scope, permit responsibility, and what happens if the first hole comes up dry. Ask about the dry-hole policy explicitly. Some drillers charge full price for a dry hole, others offer a reduced rate for a second attempt, and a few guarantee water. Also ask about the estimated timeline, the payment schedule, and whether the quote includes water testing. Be cautious of quotes far below the local average, which may exclude casing or grouting, or come from an unlicensed operator. Verify the driller license with your state agency and ask for references from recent jobs in your area. A reputable driller will welcome these questions and will explain the geology they expect to encounter.

Is Drilling a New Well Worth It

For most rural properties without access to municipal water, drilling is not optional, it is the only path to running water. The question is whether the investment pays off compared with alternatives. A complete new well system typically costs $10,000 to $20,000 all in, which sounds steep until compared with the alternatives. Hauling water costs $100 to $300 per delivery and quickly exceeds well costs within a few years. Connecting to a distant municipal line can cost $15,000 to $50,000 or more in extension fees, if it is available at all. A well also adds property value, often recovering much of its cost at sale, and it eliminates monthly water bills, though it adds electricity, testing, and maintenance costs of roughly $300 to $600 per year. The main risks are dry holes, low yield, and poor water quality, all of which are mitigated by researching local well logs and hiring an experienced local driller. If you already have a well and are weighing repair against replacement, the math is different. A failing pump or tank is far cheaper to fix than drilling anew, so start with our well pump repair cost guide and pressure tank replacement cost guide before considering a new well.
