Short answer: most pool pump repairs in Jacksonville are a capacitor, a shaft seal or a motor, at an estimated $150–$900. We diagnose at the pad, show you the failed part, and price a repair and a replacement side by side when the pump is near the end of its life.
What your pump is telling you
- Humming, not spinning. Usually a failed start capacitor or a seized bearing. The capacitor is cheap; the bearing means a motor.
- Screeching or grinding. Worn motor bearings. They do not recover, and they get louder until the motor stops.
- Tripping the breaker. A shorted motor winding, water in the motor from a failed seal, or a wiring fault at the pad. This one needs a meter, not a guess.
- Dripping under the motor end. The shaft seal has gone. Caught early it is a seal kit; left alone the water ruins the motor bearings too.
- Running, but weak flow. A clogged impeller, a full basket, a dirty filter or air on the suction side. Often no parts at all.
Filters that have stopped filtering
Cloudy water that will not clear despite good chemistry is usually the filter. Cartridges wear out and tear; DE grids split and let powder back into the pool; sand filters channel, so water takes the easy path straight through. Northeast Florida adds its own load in spring, when the oak pollen arrives and coats everything, including the pool. Filters that were borderline in winter often fail in March and April. A rising pressure gauge that drops back after cleaning is normal; one that reads low and clean water that will not come is not.
Salt cells, lights and automation
Salt chlorine generators are common on newer Jacksonville pools, and the cell is a wear part with a working life measured in seasons, not decades. Before we price a new cell we check the salt reading, flow switch and board, because a cell that reads as failed is sometimes a flow problem. Control panels and automation systems are the other quiet failure, and Florida's summer lightning is hard on them. A panel that has stopped switching the pump, heater or lights often needs one board or relay rather than a whole system.
Repair prices on the pad
| Job | Estimate | What it covers |
|---|---|---|
| Pump capacitor replaced | $150–$300 | The usual fix for a pump that hums and won't start |
| Shaft seal and o-ring kit | $200–$450 | Stops a drip at the motor end |
| Pump motor replaced | $450–$900 | Keeps the existing pump housing |
| Single-speed pump, supplied and installed | $700–$1,300 | Like-for-like replacement |
| Variable-speed pump, supplied and installed | $1,200–$2,500 | Lower running cost; programming included |
| Filter cartridge, installed | $120–$350 per element | Size and brand set the price |
| Filter rebuild: DE grids or sand change | $250–$650 | Grids, manifold or laterals, new media |
| Filter replaced, supplied and installed | $500–$2,000 | Tank, valve and plumbing tie-in |
| Salt cell replaced | $700–$1,800 | Depends on cell size and the system it plugs into |
| Control board or automation repair | $300–$900 | Diagnosed first; often a board or relay |
These are estimates built from Florida pool contractors' published pricing and parts costs, gathered for this page. Brand, horsepower and how the pad is plumbed all move the number. You get a written price for your equipment before we order a part. The full table, with leak, heater, tile and surface work, is on our pool repair price guide for Jacksonville.
When a new pump is the better money
Since 2021, federal efficiency rules have pushed most replacement pool pumps toward variable-speed models, and for a Florida pool that runs its pump every day of the year that is good news. A variable-speed pump run at low speed for longer moves the same water for a fraction of the power. If your single-speed pump needs a motor and is already a decade old, we will show you the motor price next to a variable-speed replacement and let you decide. Call (904) 890-0717 to set up a visit.
Common questions
Should I repair my pool pump or replace it?
If the housing is sound and the motor is the only fault, a new motor or capacitor is the cheaper fix. Once the housing is cracked, the motor is a discontinued size, or the pump is single-speed and running long hours, a variable-speed replacement usually pays for itself in power savings.
Why does my pump lose prime?
Air is getting in on the suction side: a loose pump lid, a dry lid o-ring, a cracked fitting before the pump or water low enough that the skimmer is sucking air. We check them in that order, because that is the order of how often each one is to blame.
Can you work on equipment we did not buy from you?
Yes. We service equipment from the major manufacturers whoever installed it. If a part is no longer made, we explain the replacement options and what each one costs before anything is ordered.
