Well pump replacement cost in NH (2026)

The biggest factor is how deep the pump sits. In our towns, the median drilled bedrock well is roughly 365–505 feet deep, so many local jobs fall in the upper ranges below. These are published national figures, not quotes.

Typical ranges by depth (submersible pumps)

Source: The Well Guide, 2026. These ranges assume scheduled weekday work. The same source says emergency or weekend service adds 25–50% to the labor portion. One regional comparison puts New England costs about 15–25% above the national average because of labor costs and deep frost lines (WellPumpReplacementCost.com).

What’s in a quote

• The pump: roughly $300–1,500 depending on horsepower and brand.
• Pipe and wire: replacing them adds about $1–3 per foot of depth, or about $400–1,200 on a 400-foot well.
• Control box (on 3-wire pumps): about $100–400.
• Labor and the hoist truck: pulling a pump from 400 feet can take a two-person crew 4–8 hours.

Source for all four: The Well Guide. A pressure tank replacement is a separate line item, typically $600–1,500 all-in (The Well Guide). See pressure tanks.

How to compare quotes

• Ask for the pump brand, horsepower and warranty.
• Ask whether drop pipe, wire, check valve and torque arrestor are being replaced.
• Ask whether the pressure tank was tested, and whether it should be replaced at the same time.
• Confirm the installer’s NH pump installer license on the NHDES lookup.
