Labor costs range anywhere from $255-$377. How much you'll pay for labor will vary widely depending on your location and the expertise of the professional you hire. 

A professional will consider how long the project will take, how difficult it will be, and the cost of materials and equipment when creating your quote. 

Repairing a sump pump costs less than replacing one. National average pricing for sump pump repairs range from $85-$650, according to Thumbtack data.

There are a lot of factors that determine the cost of your sump pump replacement. Here are some of the factors that can impact costs:

New installation vs. replacement.

In most cases, replacing an existing sump pump is cheaper than installing a brand-new one. On average, sump pump installation costs $728-$1,100. New sump pump installation often requires more work and materials, which increase the cost.

"Replacing a sump pump is relatively inexpensive compared to installing one for the first time," says Xavier Kirksey Ivery, owner of Xcellent Renovations in Galloway, Ohio. "Installing a sump pump when one isn't existing will require jackhammering, digging, and new piping."

Also, "there would need to be a perimeter drain tile that would need to be installed, along with the pit itself and electrical work to power the pump," says Mike Turney, service manager at Lifeline Plumbing, Heating, and Cooling in Dundee, Illinois. "If the homeowner has an existing sump pit installed, it would be cheaper than if there was no pit installed in the home."

Type of sump pump.

The type of sump pump you choose will naturally impact the cost. Several types are available today, including pedestal sump pumps and submersible sump pumps.

"The most common type of replacement is a submersible pump," says Xavier. "The difference between a submersible pump and pedestal pump would be that a submersible pump is designed to be underwater and, most of the time, installed in deep basins."

Submersible pumps are typically more expensive than pedestal and battery backup models. However, the extra cost may be worth it. Submersible sump pumps tend to be quieter, more powerful, and less likely to overheat than pedestal pumps.

Sump pump capacity and horsepower.

The sump pump's capacity, measured in gallons per hour (GPH) or gallons per minute (GPM), can affect its price. A higher-capacity pump is usually more expensive. 

"The most common pricing model used to determine a sump pump is the horsepower of the sump pump," says Xavier. "For example, when replacing a sump pump, it is also good practice to install the same or more horsepower. The horsepower of a sump pump determines the gallons per minute that can be discharged. So, typically, a 1/2 horsepower pump would cost more than a 1/4 horsepower pump." 

Project complexity.

Several details can complicate this project, which may increase the cost. For example, the installation cost may be higher if the sump pit is hard to access.

Does your project require additional plumbing or electrical work? This may also increase the cost and time it takes to complete the project.

Are you thinking about DIY-ing this project? Before you replace the sump pump on your own, consider the potential damage you may accidentally cause if you don't install the pump correctly.

For example, leaks and basement flooding can occur if the pumps or fittings are not primed and glued correctly, says Mike.

"If the pump fails or is not installed correctly, it may result in more projects needing to be done," says Xavier. For example, you may need to pay more for "dry-out services, mold remediation, and the replacement of porous materials."

So "while a homeowner may be able to perform the task, it is better to have a professional install a sump pump," adds Xavier. "There is a risk of flooding your basement, so it is best to pass that risk on to a licensed professional."

Replacing a sump pump can be costly, but there are several ways to save money without compromising quality. Here are some tips:

• Understand cost-saving options and alternatives. Look for sump pump models that offer the best value for your money, considering factors like durability, warranty, and energy efficiency. While it may be tempting to choose the cheapest option, investing in a high-quality sump pump can save you money in the long run by reducing maintenance and replacement costs.
• Compare quotes from multiple contractors. Don't settle for the first contractor you find. Get quotes from multiple contractors to compare prices and services. This will give you a better idea of the average cost for sump pump replacement in your area.
• Maximize energy efficiency and longevity. Opt for an energy-efficient sump pump to save on your utility bills. Look for models with high energy efficiency ratings.
• Regular maintenance and proper installation can also extend the lifespan of your sump pump, saving you money on premature replacements.
• Opt for a reliable, mid-range pump from a reputable brand rather than the most expensive option. As long as the brand offers good customer service, this is a great way to balance cost and quality.
• You can consider handling the replacement yourself, but only if you're well-versed in the plumbing skills needed to complete the job.
• Watch for promotions or discounts offered by manufacturers or local suppliers.

You can replace your sump pump without breaking the bank by making informed choices and finding small ways to cut costs.

Recognizing the signs of a failing sump pump is essential to prevent costly damages and protect your property. Common indicators include:

• Unusual noises, such as grinding or rattling, suggest mechanical issues. Also, you might need a replacement "if the pump is making a pumping noise, but there is no water coming out of the discharge pipe outside of the home," says Mike.
• If it constantly runs or cycles on and off frequently, it could indicate a malfunctioning float switch or a clogged impeller.
• Water pooling around the sump pump or a foul odor may indicate a leak or damage to the pump.
• The sump pump is taking longer than normal to eject water out of the pit. If water is reaching the top of the pit but is not being pumped out, Mike says, that could be another sign that a replacement is needed.

Timely sump pump replacement is critical to maintain the effectiveness of your basement waterproofing system and prevent flooding. A failing sump pump can cause extensive damage to your property, including mold growth, rotting wooden structures, and the destruction of valuable belongings.

Don't wait until it's too late. Replace your sump pump at the first sign of trouble to avoid the headache and expense of a flooded basement. Investing in a new, reliable sump pump will give you peace of mind, knowing your basement is protected from water damage.
