Sump pump installation cost (2026)

By USA Expert Plumbing Editorial Team. Updated . 1 min read.

Short answer

Installing a new sump pump with a new pit typically costs about $800 to $1,500 in 2026, with Angi putting the average near $1,100 and complex jobs reaching $3,000 or more. Replacing a pump in an existing pit is much cheaper, usually about $300 to $750. A battery backup adds several hundred dollars.

A sump pump sits in a pit at the lowest point of a basement or crawl space and pumps groundwater away from the foundation. The biggest cost factor is whether you already have a pit.

Figures are 2026 national estimates compiled from published cost guides such as Angi, HomeGuide and This Old House. Prices in high-cost metro areas often run above these ranges.

What drives the price

  • A new pit. Cutting through the basement slab, digging the pit and setting a basin is most of the labor on a new install.
  • Pump type. Pedestal pumps cost less and are easier to service; submersible pumps are quieter and more powerful.
  • Horsepower. Homes with a lot of groundwater need a stronger pump.
  • Discharge line. A longer or buried line costs more. It must carry water well away from the foundation.
  • Electrical work. A dedicated, properly protected outlet may be needed.
  • Drain tile. An interior perimeter drain system is a waterproofing project and costs far more than the pump alone.

Is a battery backup worth it?

Storms that bring heavy rain also knock out power, which is exactly when a sump pump is needed. In a finished basement or an area with frequent outages, a battery backup or water-powered backup is usually worth the extra cost.

How long a sump pump lasts

Most sump pumps last about 7 to 10 years. Replacing an aging pump before it fails costs far less than cleaning up a flooded basement. Test it a few times a year by pouring a bucket of water into the pit and making sure it starts and shuts off.

Common questions

Can I replace a sump pump myself?

Swapping a pump in an existing pit is a common DIY job for handy homeowners. Cutting a new pit, electrical work and discharge lines are better left to a pro.

Does a sump pump need a permit?

Some cities require permits for new installations or for connecting the discharge. Check with your local building department.
