Straight 2026 numbers for rural Fresno County: what a new well, a pump replacement, and the extras in between actually run, what moves the price, and how to get a quote you can trust.
These are typical ranges for rural Fresno, Madera, and northern Kings County properties. Depth is the master variable: almost every line below scales with how far down the water is.
$15,000 to $40,000+ drilled, cased, developed, and pumping. That includes the borehole, casing and grout seal, a submersible pump sized to the well, pressure tank, and basic electrical. Shallow, easy ground lands at the low end; deep wells in hard formations run past the top of the range.
$2,000 to $6,000 for a like-for-like submersible pump swap, including pulling the old unit, the new pump and motor, drop pipe inspection, and a control box if needed. Larger horsepower pumps for deep wells or ag use sit at the top of the range.
Typically $600 to $1,800 installed depending on tank size. A waterlogged tank is the most common cause of the short-cycling that burns pumps out, so it is often replaced alongside the pump rather than after it fails again.
Typically $3,000 to $10,000+ when a well is structurally sound but the water table has dropped. It is the cheaper path when the casing is good; when the casing has failed, a new well is usually the honest recommendation.
Agricultural wells are a different scale entirely: bigger diameters, bigger pumps, and deeper bores routinely run well into six figures. The ranges above are for residential and small-ranchette systems, which is what most Fresno County homeowners are budgeting for.
Two neighbors a mile apart can get quotes thousands of dollars apart and both be fair. Here is why.
Depth to water: Drilling is priced largely by the foot, and Fresno County water tables have been falling. A 180-foot well and a 420-foot well differ by five figures before any equipment is discussed. Your contractor should talk expected depth, and what happens to the price if the bore has to go deeper, before the rig rolls.
Geology: Sand and gravel drill fast. Cobble, hardpan, and fractured rock slow the bit, wear tooling, and can force a larger casing or a different drilling method. Ground conditions are the biggest reason honest quotes carry a range instead of a single number.
Casing size and pump horsepower: A 5-inch residential casing with a 1 HP pump is standard. Step up to a 6-inch casing, a 3-5 HP pump for a big home or small farm, or a constant-pressure system, and equipment costs climb quickly.
Electrical and trenching: If power has to be trenched a long way from the panel or meter to the wellhead, that distance is real money in copper and labor. Wells set close to existing power are cheaper to finish.
Permits and testing: Fresno County well permits, required water testing, and final inspection add a few hundred to a couple of thousand dollars depending on the work. Contractors who "skip the permit to save you money" are creating a problem you will own at resale.
A real well quote cannot be given over the phone, and any contractor who names a firm price sight-unseen is guessing with your money. An accurate quote starts with a site visit: the contractor looks at access for the drill rig, checks the distance to power, reviews nearby well logs for expected depth, and talks through what the well has to supply (house only, house plus landscape, or house plus acreage).
Ask for the quote in writing with the depth assumption stated, the per-foot rate if the bore goes deeper than expected, and the pump and tank equipment listed by size and brand. Get the permit and testing fees itemized rather than buried. Two or three written quotes built on the same assumptions will cluster closely; the outlier, high or low, is the one to question.
Through this site the estimate is free and there is no obligation. Tell us your property location, what the well needs to serve, and whether you have an existing well, and a licensed local contractor will schedule the site visit that a real number requires.
Call now if: You have no water at all, the pump is short-cycling (clicking on and off every few seconds), breakers keep tripping, or you see sand and sediment surging into the house. Short-cycling in particular destroys pump motors fast, so a "wait and see" week can turn a tank repair into a full pump replacement.
It can usually wait if: You are planning a new home, a second well for irrigation, or replacing an aging but working system on your own schedule. Planned work is cheaper work: you can collect written quotes, schedule outside the summer emergency rush, and time the job around your construction or planting calendar.
Straight answers on the questions we hear most. Ranges are typical for the area, not quotes.
A complete new residential well in Fresno County typically runs $15,000 to $40,000+, with depth as the biggest driver. That range covers drilling, casing, the pump system, pressure tank, and standard electrical. Deep wells, difficult geology, or long electrical runs push past the top of the range; shallow wells in easy ground with nearby power land at the bottom.
A like-for-like submersible pump replacement typically runs $2,000 to $6,000 installed, including pulling the old pump, the new pump and motor, and a control box if yours is due. Deep wells and higher-horsepower pumps for large homes or small farms price at the top of the range. If the pressure tank is waterlogged, expect it to be quoted at the same time, and that is usually money well spent.
Because the job underground is invisible until the rig drills it. Quotes differ in the depth they assume, whether permits and testing are itemized or buried, the pump brand and warranty, and whether the price is fixed or per-foot past a stated depth. Compare written quotes on the same assumptions: depth, equipment, and what happens if the bore must go deeper. The cheapest quote that assumes 200 feet is the most expensive one if your water is at 380.
Deepening or rehabilitating a sound well typically runs $3,000 to $10,000+, well under a new bore, and it is the right move when the casing is intact and the problem is a falling water table. If the casing is corroded, collapsed, or the well was poorly constructed, money spent saving it is usually wasted. A drawdown test and a camera inspection, a few hundred dollars, will tell you which well you actually own.
Drilling itself is typically 1 to 3 days. The full project, including the county permit, pump and tank installation, water testing, and inspection, usually runs 2 to 6 weeks from signed quote to water in the house. Emergency pump replacements are much faster: most are completed in a single visit once the parts are on the truck.
