How much does a well inspection cost?

A well inspection is a visit from a well professional who checks the parts you can’t easily see working: the pump, the pressure tank and switch, the wiring, the casing and the cap. Water testing is often sold with it, but it is a separate lab service, and it is the part that moves the price most.

There is no official price list. The figures below come from commercial cost guides, with their dates. Treat them as estimates and compare local quotes.

What it costs

Service	Typical cost
Well inspection	$250 to $550
Lab water testing only	$100 to $350
Well inspection and water testing	$350 to $900
Well and septic inspection, same visit	$400 to $650
Home and well inspection, same visit	$400 to $830

HomeGuide, July 2025. These are averages; your local market may be higher or lower.

All five rows come from HomeGuide¹. Forbes Home gives a lower figure, $150 to $300, for a basic yearly inspection and maintenance visit, and says to expect more if repairs are needed². That is closer to a routine checkup on a well you already own. For a full inspection with lab tests and a written report, plan on HomeGuide’s range.

What a full inspection includes

The National Ground Water Association (NGWA) says a professional inspection should include a flow test, a full visual inspection, water quality testing and a written report³:

• Flow test. It checks the pump motor’s performance (amp load, grounding and line voltage) and whether the pressure tank and pressure switch work properly.
• Visual inspection. The wellhead, casing, cap, seals, electrical connections and the area around the well.
• Water testing. At minimum, coliform bacteria and nitrate.
• Report. A summary of what was found and what is recommended, with all the lab results.

HomeGuide’s list is similar and adds the control box, the pressure relief valve and the pipes, plus a check of the surroundings for possible sources of contamination¹. It also points out one limit that matters to buyers: an inspection does not evaluate the water table to confirm the well will keep supplying water in the long term¹.

Water testing is where prices differ

A basic test can tell you whether bacteria are there. A wider panel looks for metals, chemicals and radioactive elements, and costs more.

Test package	Typical cost	Usually covers
Basic	$130 to $200	Coliform and E. coli, metals and minerals, lead, nitrate and nitrite
Advanced	$220 to $450	The basic list plus volatile organic compounds and industrial chemicals
Extended	$700 to $750	Adds pesticides, plasticizers, flame retardants and radiological elements
Radiological	$200 to $500	Uranium, radon, gross alpha and beta, radium

The packages are from HomeGuide¹. This Old House gives a similar overall range for professional testing, $100 to $500⁷.

You don’t always need the biggest package. EPA recommends testing every year for total coliform bacteria, nitrate, total dissolved solids and pH, plus anything that is a known problem where you live⁵. Your local health department can tell you what that is. Our well water testing guide explains what to test for and how to find a certified lab, and the planner below builds a list for your situation.

What adds to the price

HomeGuide lists these cost factors¹:

• Well type. Drilled wells have more parts to check. Dug wells are more prone to contamination and may need more testing.
• Depth. Wells deeper than 500 feet usually cost more, because most measuring equipment only reaches that far.
• Pump type. A submersible pump, down in the well, is harder to get at than a jet pump.
• Age of the house. Homes built before the 1970s, or with lead solder in the pipes, may need extra tests.
• Location. Homes near mining, farming or heavy construction may need an extended water test.
• Travel. Some companies charge $1 to $2 per mile, which adds up for rural homes.

Buying a house with a well

This is when an inspection pays for itself. Minnesota’s Department of Health says wells are not typically looked at as part of a home inspection, and suggests contacting a licensed well contractor⁶. HomeGuide adds that a standard home inspection may include only a basic visual check¹.

• Book it early. HomeGuide estimates 2 to 3 hours on site and 3 to 10 days for lab results¹. That needs to fit inside your inspection deadline.
• Combine visits. Doing the well and the septic system together costs about $400 to $650, and many companies discount a home and well inspection booked together¹.
• Who pays. HomeGuide says the buyer typically pays¹. If the report finds a problem, get a written repair quote and use it in the negotiation.

Our checklist for buying a house with a well and septic system covers the records to ask for and the septic inspection.

If the well fails the inspection

A failed report is a list of problems with a price on each, not necessarily a reason to walk away. HomeGuide lists the usual fixes: replacing the pump, pressure tank or controls, cleaning the well, disinfecting it, adding a filter or UV unit, or cleaning up pollution sources around it¹. It gives $400 to $2,500 for a new pump and, as a last resort, $6,000 to $16,000 for a new well¹. Our guide to what a new well costs breaks that number down.

If bacteria show up, the fix is often a disinfection rather than new equipment: see what to do after a positive coliform test.

When to book one if you already own the well

NGWA recommends a professional inspection every year³. CDC’s minimum is to check the well every spring for mechanical problems and to test the water at least once a year⁴. Don’t wait for the yearly visit if something changes. Call a professional or test the water when³⁴:

• the water changes in taste, smell or color, or turns cloudy;
• the pressure or flow drops, or the pump turns on and off often;
• a water test comes back positive;
• the well was flooded, or the ground near it was disturbed;
• any part of the system was repaired or replaced.

How to pay less

• Test through the health department. EPA notes that local health departments may test private wells for free⁵, and HomeGuide says county test kits cost $20 to $75¹. That covers the water, not the equipment.
• Combine visits. Well and septic, or home and well, in one trip¹.
• Match the test to the risk. Pay for the wide panels when there is a reason: an old house, nearby farming or mining, or a known local problem.
• Compare three written quotes that list the same tests¹.
