Water well service businesses drill, repair, and maintain private wells for homes, farms, and small commercial sites. Invoices usually cover new well drilling, pump and pressure tank replacement, well pump repair, water testing, and hydrofracturing or cleaning of existing wells. Most work is done by a small crew with a drill rig, a pump hoist truck, or both.

Drilling is priced per foot, with a separate charge for casing, and often a different rate for rock versus overburden. Pump and tank work is priced as equipment plus labor, with a markup on parts, and service calls carry a trip charge or a minimum. Troubleshooting and repair are billed hourly with a truck or hoist fee. Many contractors quote drilling as a price per foot with an estimated depth, and bill actual footage drilled, so the final total can differ from the estimate. Pump installs are commonly a flat price for a package that includes the pump, pipe, wire, and fittings. Add-ons such as water testing, disinfection, hydrofracturing, and permit fees are listed separately.
| Service | Priced | Typical range |
|---|---|---|
| Well drilling (drilling and labor) | per foot | $25-65 |
| Steel or PVC well casing, installed | per foot | $10-35 |
| Submersible pump replacement (pump, labor, fittings) | flat fee | $1,200-3,500 |
| Pressure tank replacement | flat fee | $800-2,200 |
| Service call and troubleshooting | per hour | $100-185 |
| Pump hoist truck / pulling a pump | flat fee | $350-900 |
| Well disinfection (shock chlorination) | flat fee | $150-400 |
| Hydrofracturing to increase yield | flat fee | $1,500-6,000 |
Typical US ranges. Rates vary by region, experience, and job size.

Notes: Static water level 42 ft, yield 12 GPM at completion. Well log filed with the state as required. Deposit of $5,000 received. Balance due on receipt. Lab results are sent directly from the testing lab.
Many properties have more than one well, and the record needs to show which one you worked on.
Many states require well drillers and pump installers to be licensed and to show the number on contracts and records.
Per-foot billing needs actual footage that matches the well log, and the customer will want it for their records.
These show what the customer got for the money and help in any later dispute about water supply.
Pump HP, tank size, and brand matter for warranty claims and future repairs.
Pass-through fees should be itemized so the customer sees they were not markup.
Hitting rock early or drilling deeper than estimated changes the total, and the invoice should show what was agreed.
Drilling jobs usually require a deposit of 25 to 50 percent before mobilizing the rig, often with a progress payment when drilling is complete and the balance due when the pump is running or at completion. Pump and tank replacements are often due on completion, sometimes with a deposit for special-order equipment. Service calls are typically due on the spot. Late fees of 1 to 1.5 percent per month are common if stated in the contract. Checks, card, and ACH are common, and larger drilling jobs sometimes involve a bank draw or a payment from a lender. Check your local rules on lien rights and notice requirements.
Put in the quote that the price is per foot and that final cost depends on depth reached. State how you handle a dry hole or low yield so there are no surprises when you invoice.
Itemize drilling, casing, pump, tank, and testing as different lines. If the customer disputes one item, the rest of the invoice stays clear.
Extra casing, a deeper well, or a larger pump should be agreed in writing or a text before you do it, then added as its own line.
Rigs are expensive to move. Add a mobilization or trip charge for remote sites so a short job does not lose money.
Attach or reference the well log number on the invoice. It protects you if the well performance is questioned later.
Most drillers charge for work performed, since drilling time and materials are spent regardless of the result. Put this in your contract and explain it before starting, and say whether you will drill a second hole at a reduced rate.
Per foot is standard because depth is unknown. A flat rate works for pump and tank replacements, where the scope is more predictable. Some contractors quote a fixed price for a set depth and bill per foot beyond that.
It varies by state. Some states tax materials, parts, or the whole job, and others treat drilling as a nontaxable service. Check with your state department of revenue or a tax professional.
List them as separate pass-through lines at cost, or include them in the price and say so in the quote. Keep the receipts.
Many states allow mechanics liens for well drilling and pump work, but deadlines and notice rules vary. Check your state rules early, because filing windows can be short.
Send a Water Well Service estimate for approval, then turn it into an invoice when the work is done.
