Well Inspection Cost in 2026: Home-Sale Inspection & Water Test Prices
A well inspection costs $300–$600 for most homeowners, averaging $450, with a full range of $150–$900 (Angi, updated Jul 9, 2026). HomeGuide puts it at $250–$550, or $350–$900 with a lab water test. Booking a septic inspection in the same visit brings the combined bill to $400–$650.
A professional well inspection costs $300 to $600, and most homeowners pay about $450 (Angi, updated Jul 9, 2026; HomeAdvisor's Jun 20, 2026 guide publishes the same figures). Depth and add-ons set the full spread of $150 to $900: Angi puts wells up to 50 feet at $250–$350 and wells over 500 feet at $500 or more. HomeGuide's July 2025 guide is a little lower, at $250 to $550, or $350 to $900 with lab water testing.
For a home purchase, a well inspection has three parts: a flow test of the pump and system output, an equipment check of the wellhead, casing, pump, pressure tank and wiring, and a water sample sent to a certified lab. HomeGuide notes a standard home inspection covers none of that beyond a basic visual look, which is why buyers with a private well book it separately.
Well Drilling Pros connects you with independent local well pros who run well inspections and water tests. The prices below come from Angi, HomeAdvisor, HomeGuide and a state lab's posted fee schedule, all listed at the end of this guide.

What changes the price
Providers quote their own work — these are the factors that consistently move the number.
- Well depth: Angi puts wells up to 50 feet at $250–$350, 50–500 feet at $300–$500, and over 500 feet at $500 or more. HomeGuide says most sounding equipment only reaches 500 feet.
- Well type: drilled wells have more components to check, and dug wells need more water testing because they're more prone to contamination (Angi; HomeGuide).
- Pump type: a submersible pump down the well is harder to reach and check than a jet pump above ground (Angi; HomeGuide).
- Water test scope: a lab test adds $100–$350 (HomeAdvisor), and Angi prices a comprehensive inspection with bacterial analysis, mineral testing and flow-rate measurement at $700–$750.
- Location: homes near farming, mining or heavy construction often need an extended water test, and rural homes may pay a $1–$2 per mile travel fee (Angi; HomeGuide).
- Home age: HomeGuide says homes built before the 1970s, or with lead solder in the pipe joints, may need extra drinking water tests.
- Bundling: a home and well inspection together costs $400–$830, and a well and septic inspection $400–$650 (HomeGuide).
What does a well inspection include for a home sale?
The equipment check comes first. HomeGuide (Jul 29, 2025) lists a visual inspection of the casing, cap, gaskets, seals, vents, electrical conduit, storage tank and wellhead, a look around the well for nearby sources of contamination, tests of the pump motor, gauges, pressure relief valve and pipes, and checks of the control box, capacitors and wiring.
The flow test checks what the system delivers. The National Ground Water Association's recommended checkup includes a flow test to determine system output, a check of the water level before and during pumping where possible, pump motor performance (amp load, grounding and line voltage), and the pressure tank and pressure switch contacts. Angi lists flow-rate measurement as part of its $700–$750 comprehensive inspection, so ask whether a lower quote includes it.
The water test closes it out: the inspector draws a sample and sends it to a certified lab, then delivers a written report with results and recommended repairs. HomeGuide says the inspection takes 2 to 3 hours, and lab results take 3 to 10 days.
One limit to know: HomeGuide notes a well inspection doesn't evaluate the water table to confirm the well will supply water long-term. The flow test tells you what the well delivers on inspection day.
What water tests do lenders and buyers need?
HUD requires specific tests on private well water before it will accept a house for FHA mortgage insurance, and the VA has the same requirements, according to the Wisconsin State Laboratory of Hygiene's fee schedule. That lab's FHA/VA loan package covers total coliform, E. coli, lead, nitrate and nitrite for $146 (prices effective Jul 1, 2026). Requirements vary by lender and state, so ask your loan officer for the exact list before the sample is taken.
Beyond the lender's list, CDC recommends testing for total coliform, nitrate, total dissolved solids and pH, and asking the local health department about local concerns such as arsenic or radon. The well water testing cost guide has test-by-test lab prices.
How much does a septic and well inspection cost?
A well and septic inspection in the same visit costs $400–$650 (Angi, Jul 9, 2026; HomeGuide, Jul 29, 2025). Booked on its own, a septic inspection adds $150–$400 to a well inspection, depending on the location and size of the system (Angi; HomeAdvisor).
HomeGuide notes that homes with a well often rely on a septic system too, and the two are linked: CDC lists septic systems among the sources of nitrate in well water. Booking both in one visit costs less and gives you one picture of the property's water and wastewater.
Who pays for a well inspection when buying a house?
The buyer usually pays, according to HomeGuide, and mortgage companies often require a well inspection and water test before approving a loan. Because the inspection is the buyer's due diligence, get the written report and lab results before your inspection contingency runs out.
Well inspection near me: how to hire an inspector
Look for a licensed water well contractor or an inspector with InterNACHI or NGWA certification, and confirm they're licensed, bonded and insured (HomeGuide). NGWA's wellowner.org site has a Find a Contractor directory for certified water well contractors.
Before you book, ask whether the quote includes a lab water test and which contaminants it covers, where the sample will be taken, whether the flow test measures water level during pumping, and how long the report takes. A quote that leaves out the lab test isn't comparable with one that includes it.
What happens if a well fails inspection?
The report will list the repairs, and their costs are a fair basis for negotiating with the seller. Angi's figures for common repairs (Jul 9, 2026): pressure tank $300–$700, well pump $975–$2,800, a leaky well pipe $100–$300, and well casing replacement $375–$2,500. A positive bacteria test usually means disinfecting the well, which costs $80–$200 by a pro (Angi), followed by a retest.
HomeGuide's list of fixes runs from replacing the pump, pressure tank or controls, to cleaning the well, shock chlorination, a filter or UV purifier, and cleaning up contaminants around the wellhead. Drilling a new well is the last resort. See the pressure tank, pump replacement and drilling cost guides for those prices.
How often should a well be inspected?
NGWA recommends an annual checkup by a licensed or certified water well professional. Angi also says once a year, and HomeGuide says every 1 to 2 years. Also get one when you buy a home with a private well, when the well cap is opened, after septic repairs, and after flooding (Angi; HomeGuide).
How we built these numbers
The short version. Every price on this page comes from a published, cited cost guide or a lab's posted fee schedule. When no source publishes a figure we need, we make an estimate, label it as an estimate, and show how we got it. These are planning ranges, not quotes. This page is published by Cornelia Cove LLC.
How each range was built:
Headline range ($300–$600), average ($450) and full spread ($150–$900). Copied as published from Angi's well inspection cost guide (updated Jul 9, 2026). HomeAdvisor's guide (updated Jun 20, 2026) publishes the same figures. Angi and HomeAdvisor are the same company, so we count them as one source and cite the more recently updated page.
Depth bands, add-ons (septic $150–$400, advanced water testing $100–$350, comprehensive inspection $700–$750), travel fees and common repair costs. As published by Angi (Jul 9, 2026).
HomeGuide figures (inspection $250–$550, with water testing $350–$900, well and septic $400–$650, home and well $400–$830), what an inspection includes, and timing. As published by HomeGuide (Jul 29, 2025). We show HomeGuide beside Angi because the two differ.
FHA/VA water test package ($146). As published in the Wisconsin State Laboratory of Hygiene's fee schedule (prices effective Jul 1, 2026). It's one state lab's price, not a national figure.

How we choose figures: As published. We copy a source's range exactly. We don't round, blend or adjust for inflation. When sources disagree, we show both. Same numbers everywhere. This page and our water testing and pressure tank cost guides use the same figures.
