Sump Pump Installation Cost

A sump pump is the last line of defense for basements and crawl spaces that take on groundwater. It sits in a pit at the lowest point of the floor, switches on when water rises, and pushes it out through a discharge line away from the foundation. Homes with a high water table, interior drain tile or a history of basement flooding need one.

This guide covers installed prices by pump type and horsepower, the extra cost of a new pit or a backup pump, a line-item breakdown and how to compare quotes. A pump is often part of a bigger fix; see our basement waterproofing cost guide if water gets in through the walls or floor joint.

Sump pump installation cost by type

Installed cost by horsepower

Angi's installed ranges by pump size. Most homes need 1/3 to 1/2 HP; very wet sites may need more.

Cost breakdown: materials, labor, permits and extras

Line-item estimate for installing a new 1/3–1/2 HP submersible pump in a prepared basin with an above-ground discharge line and check valve. Ranges are national, as of October 8, 2026.

Labor is often 65%–80% of the bill, so the biggest swing comes from whether the crew has to cut concrete for a new pit.

What affects the price

• Pump type (pedestal or submersible) and horsepower. Pedestal pumps cost about $800–$1,500 installed and submersible pumps $1,200–$3,000. Moving from 1/3 HP ($800–$1,200 installed) to 3/4 HP or more ($1,600–$2,500) adds capacity for very wet sites.
• Whether a new basin or pit has to be cut. Breaking through a concrete floor for a new pit costs about $2,500–$5,000, while digging into a dirt floor costs a few hundred dollars. If a basin and drainage already exist, a new pump can be installed for as little as about $500.
• Discharge piping length. An above-ground discharge line runs about $150–$400, and a buried line that carries water farther from the house costs $250–$2,000, depending on length and trenching.
• Battery backup or water-powered backup. A battery backup adds about $1,000–$2,000 installed, and a water-powered backup about $1,200–$2,500. Backup batteries cost about $50–$150 to replace every few years.
• Electrical work. Pumps need a nearby grounded outlet, ideally on its own circuit. Cost guides don't publish a standard figure for adding one, but it's billed at electrician rates, and a permit ($50–$250) may be required when wiring changes.
• Existing drainage. A pump only works if water can reach the pit. Homes without drain tile may need an interior drain ($40–$120 per linear foot) or a French drain ($2,800–$6,500); see our French drain basement cost guide.

Ways to save

• Replace the pump before it fails. Swapping a worn pump in the existing pit ($350–$1,000) costs far less than emergency service plus water damage cleanup.
• Choose the pump size the site needs. HomeGuide suggests about 1/4 HP for drier areas and 1/3–1/2 HP for homes that flood often; bigger pumps cost more to buy and install.
• Bundle the pump with drain tile or waterproofing work so you pay for one concrete cut and one mobilization.
• Get at least three written quotes from plumbers or waterproofing contractors and compare pump brand and model, backup option, discharge route and warranty.
• Ask your city or utility about flood-mitigation or backflow-prevention rebates; some local programs help pay for sump pumps or backups.
• Skip extras you won't use, such as smart monitoring ($100–$500), unless you travel often or have a finished basement.

Related questions people ask

What is the cost of sump pump installation?

Angi reports a national average of about $1,100, with most installs between $800 and $1,500; HomeGuide puts the average at about $1,600 ($600–$2,500). The difference is mostly whether a pit already exists.

How much does a sump pump cost with installation?

The pump itself costs about $100–$800, and labor and materials bring the installed total to $600–$2,500. A primary pump with a battery backup runs higher, and a new pit in concrete can make the full job $2,500–$5,000.

How much does sump pump installation cost near me?

Local prices follow plumber rates, which run about $45–$150 per hour, plus any permit fee ($50–$250). Expect the upper end of the national range in big metro areas; the fastest way to a firm number is three on-site quotes from local plumbers or basement waterproofing companies.

How to get an accurate quote

Get at least three written quotes from licensed plumbers or basement waterproofing contractors. Give each the same information:

• Whether you have an existing pit, the floor type (concrete or dirt) and where water appears.
• How often the current pump runs, if you have one, and whether the basement is finished.
• Where the discharge line can exit and how far water must be carried from the house, plus whether an outlet is nearby.
• Ask each bidder to list the pump brand, model and horsepower, basin and lid, check valve, discharge route, backup option, permit and warranty.

FAQ

How long does a sump pump last?

Angi says most pumps last 7–10 years. Pedestal pumps can last up to 30 years because the motor stays dry, while submersible pumps typically last 5–15 years.

Can I install a sump pump myself?

Swapping a pump in an existing pit is a common DIY job; Angi puts DIY materials at about $300–$800. Cutting a new pit in concrete or adding a circuit is best left to pros, and electrical work may need a permit.

Does a sump pump need maintenance?

Yes. Test it a few times a year by pouring water into the pit. Professional maintenance runs about $100–$300 per visit, and backup batteries need replacing every few years.
