On average, expect to pay $309 to $755 for a professional sump pump replacement, according to our research. Costs may exceed that range; depending on where you live, labor costs and other factors, you could pay around $1,500 or more.
Pump type
There are two types of sump pumps: pedestal and submersible.
Pedestal: Pedestal pumps are smaller and thinner than submersible pumps, with the motor at the top. They’re usually less expensive to buy and repair, though they’re typically noisier and more prone to issues.
Submersible: Submersible pumps are much larger than pedestal pumps and are installed in a sump pit. They’re usually quieter and safer, but they typically cost more because they're more powerful.
Labor
Labor costs around $45 to $200 per hour to install a replacement sump pump, though costs vary widely by location and company. Fortunately, the process usually takes only about an hour.
When should a sump pump be replaced?
Usually, you'll notice signs that your sump pump needs to be replaced. Some big signs that your sump pump needs to be replaced include:
Water in your basement isn’t draining as it should be
Mold growing in the basement
Strange sounds or vibrations coming from the sump pump
Short cycling, meaning the pump continuously cycles on and off
Can you replace a sump pump by yourself?
If you replace a sump pump yourself rather than hiring a professional, you can save hundreds of dollars in labor. Your local home improvement store should have new sump pumps for sale, and plenty of online tutorials can guide you through the process. It just takes a few steps and very few tools.
Do home warranty plans cover sump pump replacement?
Many home warranty plans cover sump pump replacement, along with many other home appliances and systems. This means you may only need to pay a deductible to replace your sump pump, which can save you a lot of money.
Check your home warranty contract for any coverage limitations. For example, some companies may only cover the repair up to a certain amount. If your replacement price exceeds that cap, you’ll need to pay the difference out of pocket.
