How much does sump pump repair cost

Installed prices. HomeGuide says after-hours emergency repairs cost $50 to $150 more.

Do this now: sump pump stopped and water is rising

1. If water has reached outlets, cords or the electrical panel, stay out of the basement. The Red Cross warns not to touch electrical equipment that is wet or while standing in water.
2. Check the power: HomeGuide's first checks are the outlet and the fuse or breaker.
3. Pour a bucket of water into the pit and watch whether the float rises and starts the pump (HomeGuide).
4. Unplug the pump before you reach in to clear debris from the pit or the impeller (HomeGuide).
5. Photograph the damage before you clean up, then call your insurer. FEMA says to take photos before cleanup begins.
6. Call the plumber line if the pump still will not run, and ask for the after-hours charge; HomeGuide puts it at $50 to $150 extra.

Is it urgent? When a sump pump failure cannot wait

A dead sump pump is urgent when the pit is filling or rain is on the way, and HomeGuide says after-hours repairs add $50 to $150 to the bill.

• Call now: water rising in the pit or already on the basement floor.
• Same day: a pump that runs nonstop; HomeAdvisor prices that repair at $150 to $500.
• Same day: a pump that hums but moves no water. Unplug it and check the impeller first.
• Can wait: dry weather and a pump more than 10 years old. HomeAdvisor advises replacing pumps that old; book it before the wet season.

Sump pump not working: causes and fixes

Most sump pumps that stop working have lost power, have a float that never rises, have a failed check valve, or have debris blocking the impeller, according to HomeGuide's February 2026 guide. Its checks, in order:

1. Confirm the pump is plugged in and has power: check the outlet and the fuse or breaker.
2. Pour a bucket of water into the pit and watch the float rise and start the pump.
3. Clear loose items and debris out of the pit.
4. Pour water in again to test the check valve. If water flows back into the pit, the valve needs replacing.
5. Unplug the pump before removing the bottom screen to clear the impeller.

If those checks do not fix it, the symptom points to the part. HomeGuide names the likely cause; HomeAdvisor prices the repair:

How long do sump pumps last

A sump pump lasts about 10 years with proper maintenance, HomeAdvisor says, and HomeGuide puts the range at 7 to 10 years, or about 5 for a pump that runs often.

Pump type matters. HomeGuide gives pedestal pumps 10 to 15 years or more and submersibles 7 to 10; Fixr's ranges are wider, 15 to 30 years for pedestal and 5 to 15 for submersible. HomeAdvisor advises replacing a pump more than 10 years old, and its replacement average is $1,363.

• Test it monthly in the rainy season with a bucket of water in the pit (HomeGuide).
• Clean the pit, pump, check valve and float once a year (HomeGuide).
• Add a battery backup so the pump runs in a power outage; Fixr puts adding one at $150 to $250.

How often should you replace a sump pump

Plan on replacing a sump pump by the time it is 10 years old: HomeAdvisor advises replacing any pump older than that, and InterNACHI's life expectancy chart lists a sump pump at 7 years. Fixr says to replace it sooner if you notice any of these:

• A strong foul odor, excessive noise, or standing water in the basement.
• Smoke, or a float that keeps catching and has to be freed.
• Repairs that keep coming back, or a pump that only runs briefly before it needs attention again.

How much is a sump pump

The pump alone costs $80 to $800 for a pedestal model and $90 to $1,000 for a submersible in Fixr's guide. By motor size, Fixr lists a 1/3 HP submersible at $90 to $250 and a 1/2 HP at $160 to $400. Installed replacement prices are in the next section. If water already got in, see basement flooding for what to do first.

Sump pump replacement cost: submersible vs pedestal

Sump pump replacement averages $1,363 in HomeAdvisor's 2026 data, with most homeowners paying $645 to $2,120. HomeGuide's straight swap is cheaper, $400 to $700, and Fixr's is $350 to $1,000. HomeAdvisor says pedestal pumps usually last longer than submersibles, and its repair and replacement prices for submersibles run higher.

HomeGuide, Feb 2026; Fixr, Jan 2025; HomeAdvisor, June 2026.

HomeAdvisor says sump pumps last about 10 years with maintenance and advises replacing pumps older than that. HomeGuide says a pump that runs often may last only about five years, and that plumbers often recommend replacing a failed pump because repair and replacement costs are close.

Sump pump installation cost

A new sump pump installation averages $1,400 in Fixr's guide, with a typical range of $800 to $2,000. The low end, about $500, is a pedestal pump in an existing pit; the high end, about $4,000, adds a new pit, two pumps, underground drainage, a battery backup and an alarm. Fixr prices digging a new pit at $500 to $1,200 and says permits are generally not required unless the job includes electrical or structural work. By location, Fixr lists crawl spaces at $650 to $1,500 and basements at $800 to $2,000.

Battery backup sump pump: cost and why it matters

A battery backup keeps the pit from filling when a storm knocks out power, which is when you need the pump most. FEMA advises buying sump pumps with backup power and making sure the system can run on backup batteries or a generator. Fixr puts adding a battery backup to an existing pump at $150 to $250, and a backup unit at $150 to $2,000. A water-powered backup runs $200 to $900 and a combination unit $500 to $1,500. HomeGuide lists a battery backup at $150 to $500 installed, and HomeAdvisor prices a replacement battery at $250 to $500.

A standby generator can also run the pump; whole house generator cost has the prices.

Sump pump maintenance

Test a sump pump monthly in the rainy season by pouring a bucket of water into the pit, HomeGuide advises. It also suggests a quarterly test, a yearly cleaning of the pit, pump, check valve and float, and taking off the discharge hose in winter so it does not freeze. A maintenance plan runs $100 to $250 a year in HomeGuide's figures.

Does insurance cover a failed sump pump

Standard homeowners policies do not cover flood damage, FEMA says. Fixr lists a water backup insurance rider at $50 to $250 a year on top of the premium; ask your insurer what it covers. If water got in, call your insurer before cleanup and do not sign over your claim to a contractor. FEMA also recommends having a licensed plumber install sewer backflow valves to keep floodwater and sewage from backing up through drains. If sewage did back up, see sewage cleanup.

Sump pump repair near me: what to ask before you book

• Is there a diagnostic fee, and is it credited to the repair? HomeGuide says to ask both.
• What is the hourly rate? HomeGuide lists plumbers at $45 to $150 an hour; HomeAdvisor's range is $45 to $200.
• Repair or replace? On a pump older than 10 years, ask for both prices.
• Battery backup: ask what the battery costs to replace and how long it runs.
• License and insurance: ask for the license number and proof of insurance.

If the basement already flooded, drying comes first: the EPA's 24 to 48 hour window applies, and water damage restoration covers it. Other plumbing jobs are on the plumbing hub, including burst pipe repair and drain cleaning. Prices for other trades are on home repair costs.
