What drives the price
- New pit or existingCutting through a basement slab, digging the pit and adding drainage is most of the cost of a new install.
- Pump typeSubmersible pumps are quieter and more powerful. Pedestal pumps are cheaper and easier to service.
- Backup powerStorms that flood basements often knock out power, so a battery backup is a common add-on.
- Discharge routeThe water has to exit away from the foundation, and long or complicated discharge runs cost more.
How this estimate works
The calculator starts from the installed price range for the type you pick, then adds any extras you tick. The headline number is the midpoint of your range. Low-end prices fit simple jobs in lower-cost areas. High-end prices fit complex jobs, premium brands and high-cost metros.
Get at least three written quotes before you hire. Ask each contractor to list materials, labor, permits and disposal separately so you can compare them line by line. Read how we build our ranges.
