Sump pump replacement costs $800 to $3,000 in 2026
Angi puts a professional install at about $1,100 on average. A Chicago area contractor puts 2026 installs at about $1,400, with a range of $500 to $4,000. Swapping a pump in an existing pit is the cheap end. Digging a new pit and running new discharge pipe is the top.

These rows are our estimate. We took the typical national range and adjusted it for local labor costs, which run about 20 percent lower in the cheapest states and about 30 percent higher in the dearest ones. Basements, and so sump pumps, are most common in the Midwest and Northeast.
The backup is the part that saves you
A sump pump fails in two common ways: the motor wears out, or the power goes out in the same storm that fills the pit. The second one is why a backup matters. Angi's basement waterproofing guide puts a new backup battery at $100 to $300 every 3 to 5 years, and warns that a system without one can fail in the first storm that cuts the power.
If you are replacing a pump, this is the cheapest time to add a backup, because the plumber is already there and the pit is open.
When to replace before it fails
Angi's guide gives pumps a life of about 7 to 10 years. If yours is near that age, replacing it on your schedule costs less than an emergency call at night with water on the floor. Test it twice a year by pouring a bucket of water into the pit and watching it cycle.
Why this costs more in 2026
Pumps are motors and cast housings shipped by truck, and PVC discharge pipe is made from oil and gas.
Fuel is the common thread. AAA's national average for diesel passed $6 a gallon for the first time on September 11, 2026, up from about $3.70 a year earlier (CBS 8 reporting AAA). Every truck roll and every delivery carries that. Materials moved too. Associated Builders and Contractors reported construction input prices up 4.8 percent in a year as of March 2026, the largest annual gain since January 2023, and the Associated General Contractors said diesel jumped 37.8 percent in one month, the largest one month rise since 1990 (Roofing Contractor, April 2026). Some suppliers added freight surcharges this year. Ask how long your quote is good for.
How to judge the quote in your hand
- Ask pit or no pit. A swap in an existing pit should be at the low end.
- Get the pump brand and horsepower.
- Ask for a new check valve. It is cheap and often skipped.
- Ask about a backup price while the pit is open.
- Check the discharge. It should carry water well away from the house.
Ways to pay less
- Replace before it fails. At 7 to 10 years, on your schedule.
- Test twice a year with a bucket of water.
- Add the backup now, not after a flood.
- Keep the old pit if it is in good shape.
