Sump Pump Installation Cost
Short answer: Installing a sump pump costs about $1,100 on average, and most homeowners pay $800 to $1,500, according to Angi. HomeGuide puts the range at $600 to $2,500. Submersible pumps cost more than pedestal pumps, and cutting a new pit through a concrete floor can push the total to $2,500 to $5,000. A battery backup adds $1,000 to $2,000.
A sump pump sits in a pit at the lowest point of a basement or crawl space and pumps groundwater away from the foundation. Angi puts the 2026 national average for a new installation at $1,100, with most homeowners paying $800 to $1,500. HomeGuide's range is $600 to $2,500, with a national average of $1,600.
If you already have a pit and are only swapping the pump, the job is much cheaper; see sump pump replacement cost.
Cost by pump type
| Type | Installed (Angi) | Unit only (HomeGuide) |
|---|---|---|
| Pedestal | $800 – $1,500 | $100 – $400 |
| Submersible | $1,200 – $3,000 | $100 – $800 |
| Water-powered | $1,200 – $2,500 | $100 – $700 |
| Battery backup (add-on) | $1,000 – $2,000 | $150 – $800 |
| Crawl space / exterior | $1,500 – $4,000 | – |
Pedestal pumps sit above the pit, so they are easier to service but louder. Submersible pumps sit in the water, are quieter and handle more volume. Water-powered backups use municipal water pressure to run during a power outage, and battery backups keep a second pump running when the power fails.
Cost by pump size
| Size | Installed |
|---|---|
| 1/3 HP, up to 2,000 GPH | $800 – $1,200 |
| 1/2 HP, up to 3,000 GPH | $1,000 – $1,600 |
| 3/4 HP or higher | $1,600 – $2,500 |
| Dual pumps or multiple pits | $2,000 – $4,000+ |

The pit and the floor
Digging the pit is the main labor cost on a new install. HomeGuide says a concrete floor that needs a jackhammer or concrete saw puts the total at $2,500 to $5,000. Dirt floors in crawl spaces are faster to dig. A new or upgraded perimeter drainage system costs $4,000 to $12,000 (HomeGuide).
Labor
HomeGuide puts labor at $500 to $1,700, about 65% to 80% of the project. Angi lists hourly rates of $50 to $150, with minimum service fees starting at $100. Electrical upgrades, such as a dedicated outlet near the pit, add to the bill.
Other costs
| Item | Cost | Source |
|---|---|---|
| Permits | $50 – $250 | Angi |
| Check valves, pit covers, discharge lines | $50 – $300 each | Angi |
| Smart monitoring / Wi-Fi alerts | $100 – $500 | Angi |
| Annual electricity | $30 – $50 | Angi |
| Professional maintenance | $100 – $300 per visit | Angi |
| After-hours emergency surcharge | $50 – $150 more | HomeGuide |
Ways to save
- Install before the wet season rather than during a flood, when after-hours surcharges apply.
- Add the battery backup at the same visit instead of a second service call.
- Ask whether the discharge line, check valve and pit cover are included in the quote.
What a sump pump does
A sump pump sits in a pit at the lowest point of a basement or crawl space and pumps out water that collects there, sending it away from the foundation through a discharge line. It turns on automatically when the water level rises.
Types of pumps
- Submersible. Sits in the pit, quieter and less visible. The most common choice for finished basements.
- Pedestal. The motor sits above the pit. Cheaper and easier to service, but louder.
- Battery backup. A second pump that runs on a battery when the power fails, often during the storms that bring water.
- Water-powered backup. Uses municipal water pressure instead of a battery, where codes allow.
What affects the price
- Digging a new pit in a concrete floor versus replacing a pump in an existing pit.
- Discharge line length and routing to the outside.
- Electrical work if there is no outlet near the pit.
- Drainage such as interior drain tile that feeds the pit.
- Check valves and alarms, which are worth adding.
Questions to ask
- Is the pump sized for the amount of water you expect?
- Where will the discharge line exit, and will it carry water far enough from the foundation?
- Do you recommend a battery backup or a high-water alarm?
Maintenance
Test the pump a few times a year by pouring water into the pit, keep the pit free of debris, and make sure the discharge line outlet is clear.
In Texas
Basements are uncommon in most of Texas, so sump pumps are more often installed in crawl spaces or yard drainage systems. Homes in flood-prone or low-lying areas, and properties with heavy clay soil that holds water, are the most common candidates.
Where the sump pit goes
The pit is usually placed at the lowest point of the basement or crawl space, where water naturally collects. It should be away from the foundation footing and close enough to an exterior wall for a practical discharge route. If the home has interior drain tile along the foundation, the pit is tied into it so the tile drains to the pump.
Discharge routing
The pump discharges water through a pipe out of the house. It should end far enough from the foundation that water does not flow back toward the house. Many local codes do not allow sump pumps to discharge into the sanitary sewer. Some homes discharge into a storm drain, a dry well or a drainage area on the property. Ask the installer what your local rules allow.
Backup pumps
A backup pump protects against a primary pump failure or a power outage, which often happen during the same storms when the pump is needed most. Battery backup pumps run on a deep-cycle battery. Water-powered backups use city water pressure to remove water without electricity, but they use a lot of water and need a backflow preventer. A backup alarm that warns of high water is a simple, low-cost addition.
More on maintenance
Clean the pit and the pump inlet screen of debris, test the pump before heavy rain, and check the discharge line for blockages. Replace the battery in a backup pump as recommended by the manufacturer.
Permits and inspection
Some cities require a permit for a new sump pit or a new discharge line, especially if the discharge connects to a storm sewer. Ask the installer.
Is a sump pump the right fix?
A sump pump handles water that reaches the foundation. If water enters because gutters overflow or the yard slopes toward the house, fixing the grading and extending downspouts may solve the problem for less. Many homes need both.
