Sump pump repair costs $150 to $870, with national averages of $300 to $540 depending on the reference.123 Pedestal pumps run $100 to $500 to repair; submersible units $175 to $1,000 because they come out of the pit for service (HomeAdvisor, Fixr).13 Prices below are national averages* for 2026.
*National averages, not local quotes. Your price depends on pump type, the failed part, accessibility, and timing — emergency or after-hours calls add $50 to $150 (HomeGuide).2

Quick math: Fixr’s $300 average sits well below HomeAdvisor’s $531 and HomeGuide’s $540 because Fixr centers on standard fixes (its low end is a $75 float-switch fix), while the others fold in emergency calls and complex submersible jobs, our reading.123
Cost by pump type
| Pump type | HomeAdvisor | HomeGuide | Fixr |
|---|---|---|---|
| Pedestal | $100 – $500 | $100 – $480 | $150 – $500 |
| Submersible | $200 – $1,000 | $200 – $1,000 | $175 – $550 |
HomeAdvisor and HomeGuide publish identical bands for this table — they draw on shared project data, our note — while Fixr’s tighter $175 to $550 submersible range excludes emergency work, our reading.123 Pedestal pumps are cheaper to fix because the motor sits above the pit, dry and easy to reach (HomeAdvisor, Fixr).13
Cost by part (HomeAdvisor)
| Part | Repair | Replace |
|---|---|---|
| Float switch | $75 – $125 (adjustment) | $100 – $150 |
| Check valve | $10 – $30 | $125 – $250 |
| Impeller | $100 – $225 | $25 – $250 |
| Discharge pipe | $125 – $300 | $175 – $600 |
| Motor | $150 – $300 | $250 – $500 |
| Backup battery | not repairable | $250 – $500 |
The float switch is the most common failure and the cheapest fix — sometimes just a repositioning at $75 to $125 (HomeAdvisor); Fixr’s $75 low-end job is exactly this fix.13
Cost by symptom (HomeAdvisor)
| Symptom | Repair cost |
|---|---|
| Float stuck | $100 – $250 |
| Rust / corrosion | $150 – $450 |
HomeGuide pegs hourly rates at $45 to $150 for plumbers and $50 to $80 for handymen; HomeAdvisor’s band runs to $200 per hour for emergency work.12
Repair or replace?
Replacement runs $400 to $600 for a pedestal and $800 to $2,000 for a submersible (HomeAdvisor); HomeGuide puts new installation at $600 to $2,500 and notes plumbers often recommend replacement when a repair quote approaches those figures.12 A motor or battery replacement ($250 to $500 each) on an older pump is close to halfway to new, our judgment. See our sump pump installation cost guide for full replacement pricing.
Worked examples
Example 1 — stuck float, pedestal. $75 to $250 depending on whether it needs adjustment or replacement (HomeAdvisor).1
Example 2 — submersible motor repair. $150 to $300 for the motor work, toward $1,000 if the unit needs full removal and rebuild (HomeAdvisor, HomeGuide).12
Example 3 — storm-night failure (emergency). $300 average repair + $50 to $150 after-hours premium = $350 to $450, our arithmetic (Fixr, HomeGuide).23
FAQ
What fails most often? The float switch — it gets stuck or knocked out of position, and the fix can be as cheap as $75 (HomeAdvisor, Fixr).13
How much is yearly maintenance? $100 to $250 per year (HomeGuide) or $150 to $250 (HomeAdvisor) — it catches float and valve problems before a storm does.12
Can a handyman do it? For simple fixes yes, at $50 to $80 per hour; motor or pit work belongs to a plumber at $45 to $150 (HomeGuide), our judgment.2
Is repair worth it on an old pump? When the quote nears the $400 to $600 pedestal or $800 to $2,000 submersible replacement range, replace (HomeAdvisor), our judgment.1
Why did my pump die during a storm? Power outages stop the pump; a battery backup ($250 to $500 installed, HomeAdvisor) keeps it running, their pricing.1
