Cost to Repair a Sump Pump by Type

Sump pumps come in two types: submersible and pedestal. The type you have directly impacts the cost of your repairs because each has unique features and characteristics. Different problems can occur with each type, and the costs vary accordingly.

TypeAverage Costs (Labor Included)
Pedestal$150 - $500
Submersible$175 - $550

Pedestal Sump Pump Repair

The average cost of pedestal sump pump repairs is between $150 and $500. They have the motor at the top, where it stays dry, with the drawtube at the base of the sump pit. These types are less expensive to install and maintain, and there is less risk of motor issues. However, problems can still occur with these pumps, such as impeller faults and valve issues.

Submersible Sump Pump Repair

Homeowners pay between $175 and $550 for submersible sump pump repairs. They are designed to be submerged in water and sit right at the base of the sump pit. They are more expensive to purchase and repair because these pumps are usually complex and involve extra labor. Common problems include motor issues, float problems, and broken impellers.

Cost to Repair a Sump Pump by Location

Location is another factor impacting the cost of sump pump repairs. Pumps can be placed in various spaces around the home, such as crawl spaces, basements, and outdoor areas. Some areas are easily accessible, while others require more work to get to, leading to higher labor costs.

LocationAverage Costs (Labor Included)
Basement$150 - $550
Garage$150 - $550
Bedroom$175 - $575
Crawl Space$200 - $600

The average cost of basement sump pump repair is between $150 and $550. The basement is the most common location for nstallation. This is because the basement is the lowest point in the house, ideal for collecting water building in the sump basin and removing it. Repair workers are used to working in basements and should charge standard fees for working with this pump.


To repair a sump pump in a garage, expect to pay between $150 and $550 to have it fixed. Just like the basement, the garage is another common location to install them. The costs are generally identical to basement pump repairs because garages are easy to access and do not pose unique challenges.


If you have a sump pump in the bedroom, repairs range from $175 to $575. The bedroom is not common for installation, but you can have pumps in bedrooms, typically in a closet space. You may want to install one in your bedroom if it is on the ground floor or the basement due to the risk of flooding. Accessing these pumps can be a little harder because they are in the closet, leading to slightly higher repair costs.

Crawl Space

Repairs for crawl space sump pumps average $200 to $600. Crawl spaces are common locations for installation, but the costs of repairing these are often higher because access can be restricted. This makes it harder for workers to do the repairs, leading to higher labor costs.


Homeowners pay between $200 and $600 for outdoor sump pump repairs. These pumps require special landscaping and usually must be installed in their own trenches under the surface. This means accessing outdoor units can be difficult. More problems can occur with them because they are exposed to the elements. Issues like freezing and rust are common.

Cost to Repair a Sump Pump by Type of Repair

Sump pumps have a range of components, including the motor, impeller, and discharge pipe. Issues can arise with each major component of your unit, and some repairs are much simpler and cheaper to complete than others. The table below shows common repairs and the average prices for each.

Type of RepairAverage Costs (Labor Included)

Impeller$100 - $225
Discharge Pipe$100 - $225
Motor$100 - $225

Sump Pump Float Switch Repair

Sump Pump Impeller Repair

Homeowners pay between $100 and $225 for sump pump impeller repairs. The impeller pushes the water out of the sump pit. It performs a lot of work and can be exposed to tough conditions, meaning the impeller may break or become stuck or dirty. This component may require cleaning, readjustment, or patching to repair minor damages.

Sump Pump Discharge Pipe Repair

The average cost of sump pump discharge pipe repair is between $125 and $300. The discharge pipe transports water from the sump basin and out of the home. Like other pieces of piping, it can become damaged with cracks or holes. It may also become clogged. Plumbers may need to patch superficial damages or flush the pipe to remove the blockages.

Sump Pump Motor Repair

To repair a sump pump motor, expect to pay between $150 and $300. The motor is the workhorse of the unit, providing the power the system needs to drain water via the discharge pipe. Several issues can arise with motors, but some simple readjustments and rewiring can solve minor issues.

The average cost of sump pump float switch replacements is between $100 and $150.

Luckily, this is a simple and affordable job because replacement switches are inexpensive and easy to install.

Sump Pump Valve Replacement

Sump pump valve replacements range from $125 to $200. The check valve controls the flow of water and prevents the pump from re-pumping water that has already been discharged. Valves can be damaged and may need to be replaced if water flows back into the pit after being discharged.

Sump Pump Impeller Replacement

The cost of sump pump impeller replacements averages $125 to $250. The impeller is a vital part of the system, and if yours is broken, you need to replace it as soon as possible. New impellers are relatively cheap, but it can take time to install them, so most costs are for labor.

Replace a Sump Pump Discharge Pipe

The cost of replacing a sump pump discharge pipe is between $175 and $600. The total price of the replacement depends on how much piping must be replaced. Some units have short discharge pipes, but others have longer sections of piping. It mostly depends on the location. Longer pipes cost more and take longer to install.

Sump Pump Motor Replacement

To replace a sump pump motor, expect to pay between $250 and $500. The motor is usually the most expensive component, so it can be an expensive part to fix. You may need a new motor if the existing one burns out or is seriously damaged and no longer works.
