If your sump pump is humming but not pumping, cycling nonstop, or just turned 10 years old, you are probably wondering what a replacement will cost. In Lombard and across DuPage County, where spring storms, snowmelt and a high water table keep pumps busy, it is a question worth answering before the next big rain, not during it.
Here is what homeowners in the Chicago suburbs typically pay, what drives the price up or down, and how to tell whether you need a replacement at all.
Typical Sump Pump Replacement Cost in the Lombard Area
According to Angi’s 2026 cost data for the Chicago area, most homeowners pay between $829 and $1,554 to have a sump pump installed, with an average of about $1,140. Lombard prices tend to fall in that same range, since local plumbers work under the same Chicago-area labor costs.
If you already have a working pit and discharge line and you are simply swapping an old pump for a new one, the job is usually on the lower end. This Old House puts a straightforward pump replacement, including parts and labor, at roughly $350 to $1,000 nationally.
Cost by Type of Sump Pump
Here are typical installed ranges for the Chicago area from Angi’s 2026 data:
- Submersible pump: $800 to $1,500. The most common choice in finished basements because it sits inside the pit and runs quietly.
- Pedestal pump: $500 to $1,500. The motor sits above the pit, which makes it easier to service, but it is louder.
- Battery backup system: $1,000 to $2,900 as an add-on. It keeps water moving when a storm knocks out power.
- Water-powered backup: $1,200 to $2,500. It uses city water pressure instead of a battery.
Pump size matters too. A 1/3 horsepower pump, enough for many Lombard basements, typically runs $800 to $1,600 installed, while a 3/4 horsepower pump or larger for heavy water flow can reach $1,600 to $3,600.
What Affects the Price
- Existing pit and discharge line. Reusing a good basin and discharge pipe keeps costs down. A new pit cut through a concrete floor costs more.
- Pump size and quality. Cast iron pumps with a stronger motor cost more up front but usually last longer than plastic models.
- Check valve and piping. A worn check valve or a cracked discharge line is often replaced at the same time.
- Backup protection. Adding a battery or water-powered backup is the biggest single upgrade.
- Timing. Replacing a pump during a storm or after hours can cost more than a planned replacement on a dry day.
Repair or Replace?
Most sump pumps last about 7 to 10 years. A stuck float switch or a bad check valve can often be repaired. Replacement usually makes more sense if:
- The pump is 7 or more years old
- It runs constantly or cycles on and off rapidly
- You hear grinding or rattling from the motor
- You see rust or corrosion on the pump
- It failed a bucket test, where you pour water into the pit and it does not turn on

Is a Battery Backup Worth It in Lombard?
For most finished basements, yes. The heaviest storms often knock out power at the exact moment your pump is needed most. A backup system costs less than most flooded-basement cleanups, and it protects carpet, drywall, furniture and anything stored below grade.
Winter matters too. A frozen discharge line can make a pump run nonstop until it burns out, so keep the outlet clear of ice and snow. Our guide to preventing frozen pipes in Lombard has more cold-weather tips.
Tips to Get the Most From Your New Pump
- Replace before it fails, ideally in late winter before spring storm season.
- Ask about replacing the check valve at the same time.
- Make sure the discharge carries water well away from your foundation.
- Test your new pump every few months and check the backup battery once a year.
