What well work costs here

Real ranges, including the ones nobody enjoys reading. A contractor should be able to explain where in these ranges your job falls and why, before you spend anything.

Well pump replacement

The most common job, and the one you are probably here for. Nationally, replacing a well pump runs about $900 to $2,500 fitted, and the spread inside that is almost entirely about how deep your well is.

• Wells around 100 to 200 feet: roughly $1,500 to $3,000.
• Wells around 300 to 400 feet: roughly $2,800 to $5,500.

The pump itself is usually $400 to $1,500 of that. The rest is drop pipe, fittings, wire and the labour of pulling several hundred feet of pipe out of the ground and putting it back, which is the part people are surprised by.

Pressure tank

$300 to $700 for most homes, and adding one to a pump replacement already in progress typically costs $200 to $500 rather than the full price, because the labour overlaps. If your pump is failing and the tank is old, ask about doing both while the system is open.

A new well

This is where being in Robeson County genuinely helps you.

North Carolina has three geological provinces and they do not cost the same to drill. We are in the Coastal Plain, where wells go into sand aquifers and drill relatively fast, and it is the cheapest of the three:

• Coastal Plain, which is us: about $6,500 to $11,500.
• Piedmont, fractured rock and real dry-hole risk: about $9,200 to $16,500.
• Mountains, deep and slow: about $10,500 to $18,500.

Statewide the average residential well works out around $9,240 at roughly $28 to $60 a foot. If a quote you have been given sits well above the Coastal Plain range, that is a fair question to ask, and a straight answer exists: depth, casing, a difficult site, or a pump sized for something unusual.

Testing and disinfection

Small money against the rest of this list, and the reason it is on the page at all is that skipping it is how people spend the large money twice. Shock chlorination by a contractor is a short job. See what to do if your well flooded.

Common questions

How long should a well pump last?

Eight to fifteen years is normal, and hard water, sediment and frequent cycling all shorten it. A pump that is short cycling is often telling you the pressure tank has failed rather than the pump, which is a much cheaper repair. That is worth diagnosing before anyone quotes you for a pump.

Is it worth repairing or should I replace?

If the pump is under about eight years old and the fault is electrical or a fitting, repair. If it is at the end of its life and several hundred feet down, the labour of pulling it is most of the cost either way, and replacing while it is out is usually the cheaper decision over the next five years.

Why does a quote vary so much between houses?

Depth, mostly. Two houses on the same road can have wells at very different depths, and everything about the job scales with how much pipe has to come out of the ground.
