Cost Snapshot
$800 – $1,500
Installing a sump pump typically costs between $800 and $1,500, with a national average of about $1,100, based on Angi's 2026 cost data. Pedestal pumps run $800 to $1,500 and submersible pumps $1,200 to $3,000. A battery backup adds $1,000 to $2,000, and dual-pump or crawl space systems can reach $4,000. The pump itself is a small part of the bill: a Home Depot 1/3 HP aluminum pump was listed at $131.72 on 2026-10-09, with the rest going to labor, the pit, and accessories.
Typical planning range based on the published references reviewed for this guide. Use it to prepare questions and compare written, itemized contractor proposals. Actual costs vary with project scope, materials, access, permits, and local conditions.
Parts vs. Labor Breakdown
| Component | Typical range | What it covers |
|---|---|---|
| Materials / equipment | $130 – $600 | Sump pump and basin hardware. Home Depot listed an Everbilt 1/3 HP aluminum pump with a vertical float switch (model HDPS33V) at $131.72 on 2026-10-09; the upper end is a planning assumption for larger submersible pumps, since the reference covers one 1/3 HP model. Equipment only. |
| Labor | $200 – $1,200 | Plumber or drainage contractor labor, including removal, excavating or enlarging the pit, and cleanup. Angi reports $50 to $150 per hour with minimum service fees from $100. Hours are a planning assumption. Benchmark: BLS reports a May 2025 national median wage of $30.67 per hour for plumbers and pipefitters. |
| Permits | $50 – $250 | Permit where the local code requires one for a new pump or discharge line, which Angi lists at $50 to $250. |
| supplies additional | $50 – $300 | Check valve, lid, or an improved discharge line, which Angi lists at $50 to $300 per accessory. |
Cost by Size & Scope
| Size / scope | Typical coverage | Estimated installed cost | Average |
|---|---|---|---|
| 1/3 HP Pump (up to 2,000 GPH) | Typical basement or crawl space with moderate groundwater | $800 – $1,200 | $1,000 |
| 1/2 HP Pump (up to 3,000 GPH) | Higher-volume or longer discharge runs | $1,000 – $1,600 | $1,300 |
| 3/4 HP or Larger Pump (3,000+ GPH) | High water table or heavy flow | $1,600 – $2,500 | $2,050 |
| Two Pumps or Multiple Pits | Large or high-risk basement; Angi lists $2,000 to $4,000 or more | $2,000 – $4,000 | $3,000 |
Cost by Equipment & Installation Method
| Type | Spec | Typical cost | Details |
|---|---|---|---|
| Pedestal Pump | Entry level | $800 – $1,500 installed | Motor mounted above the pit on a stand, easier to service and usually less expensive. |
| Submersible Pump | Standard for finished basements | $1,200 – $3,000 installed | Sits inside the pit, quieter and better suited to heavier use. |
| Water-Powered Backup Pump | Backup system | $1,200 – $2,500 installed | Runs on household water pressure and needs no electricity or battery. |
| Crawl Space or Exterior System | Specialty installation | $1,500 – $4,000 installed | Basin and discharge arrangement for a crawl space or outside the structure. |
Additional Line Items Often Needed
| Item | Typical cost | Necessity | Notes |
|---|---|---|---|
| Battery Backup System | $1,000 – $2,000 | Recommended | Added on top of the installation; keeps the pump running during power outages. |
| Water-Powered Backup | $1,200 – $2,500 | Optional | An alternative backup that does not use batteries. |
| Alarm or Wi-Fi Monitor | $100 – $500 | Optional | Alerts you when the water level rises or the pump fails. |
| Valve, Lid or Improved Discharge | $50 – $300 | Common | Priced per accessory. |
| Electrical Work, New Drain Line and Restoration | Not quantified by the source | As Needed | Angi says these can add to the total but does not give a price. |
Frequently Asked Questions
How much does it cost to install a sump pump?
The national average is about $1,100, and most installations cost between $800 and $1,500, according to Angi's 2026 data. Pump type, horsepower, and whether you need a new pit or a battery backup change the total.
How much does a sump pump itself cost?
Equipment is a small share of the project. A Home Depot Everbilt 1/3 HP aluminum pump was listed at $131.72 on 2026-10-09. The rest of an installed price pays for labor, the basin, accessories, and any permit or backup system.
What is the difference between a submersible and a pedestal sump pump price?
Angi lists pedestal pumps at $800 to $1,500 installed and submersible pumps at $1,200 to $3,000 installed. Submersible pumps sit in the pit and are quieter; pedestal pumps are easier to reach and cheaper.
How much does a battery backup sump pump cost?
A battery backup adds $1,000 to $2,000 to the installation, and a water-powered backup adds $1,200 to $2,500. If a power outage during a storm could flood your basement, a backup is worth pricing in.
How does horsepower change the cost?
Angi lists $800 to $1,200 for a 1/3 HP pump (up to 2,000 GPH), $1,000 to $1,600 for 1/2 HP (up to 3,000 GPH), and $1,600 to $2,500 for 3/4 HP or more. Two pumps or multiple pits cost $2,000 to $4,000 or more. Angi's flow figures are guides and do not account for discharge height.
What extra costs should I expect?
Permits run $50 to $250, alarms or Wi-Fi monitors $100 to $500, and a check valve, lid or better discharge $50 to $300 each. Electrical work, a new drain line, and restoration can add more, but the source does not price them.
