A full leak detection in Greenville — pressure testing every line, dye testing the shell and listening for underground breaks — typically runs $250–$500, with the repair priced separately:
| Job | Typical Greenville price |
|---|---|
| Full leak detection (pressure + dye + electronic) | $250–$500 |
| Pressure test only | $150–$300 |
| Skimmer or return fitting repair | $300–$1,150 |
| Light niche / conduit seal | $250–$875 |
| Vinyl liner patch | $100–$300 |
| Structural crack repair (staples, epoxy) | $500–$2,400 |
| Underground plumbing repair | $500–$2,900 |
South Carolina labor rates are close to the national baseline used for these estimates. Most leaks turn out to be at fittings, the skimmer throat, the light niche or the equipment pad — cheap fixes once found. Underground line breaks that need the deck cut cost the most, so ask how the company pinpoints them before digging.
A 24-hour bucket test tells you whether the loss is evaporation and whether it happens with the pump on or off — the two facts that shape the detection visit.

Coastal builds sit in sandy soil with high water tables — dewatering, hydrostatic relief, and never fully draining are standard practice, and salt air pushes equipment choices toward corrosion-resistant hardware. Upstate clay behaves like Georgia's: drainage design matters. Soil movement, tree roots and old fittings are the usual culprits; a leak that appears after a drought or a wet season often traces to the ground shifting around the plumbing.

Run a bucket test for 24 hours with the pump on, then off, and note the difference — losing water only with the pump running points to the pressure side, only with it off to the suction side or shell. Check the pad for wet ground and the backwash line. That information lets the company quote the right test and often shortens the visit.
A full leak detection in Greenville, SC — pressure testing the lines, dye testing the shell and electronic listening — typically runs $250–$500, with a pressure test alone at $150–$300. Repairs are priced separately: a skimmer or return fitting $300–$1,150, a light niche seal $250–$875, a structural crack $500–$2,400, and an underground plumbing repair $500–$2,900 depending on how much deck has to be opened. South Carolina labor is close to the national baseline used for these estimates.
Do a bucket test: set a bucket of pool water on a step, mark both water levels, and compare after 24 hours with the pump running, then repeat with it off. Evaporation drops both marks equally; a leak drops the pool more. Summer evaporation runs roughly a quarter inch a day, more with wind, heat and a spa spillover. Losing an inch or more a day, wet spots around the deck or pad, or air in the pump basket point to a leak.
Usually. Fittings, skimmer throats, light niches, small plaster cracks and vinyl patches are repaired underwater with epoxy, putty or patch kits. Underground plumbing is repaired by cutting a small section of deck, or by relining or rerouting the line. Draining is reserved for large structural cracks or a full resurfacing.
Evaporation alone typically costs an inch or two a week in Greenville during late April through early October, more in hot, dry or windy weather and when a heater or spa spillover is running. Splash-out and backwashing add to it. If you are topping off more than a couple of inches a week, or the autofill runs constantly, get a detection visit — a small leak wastes thousands of gallons and the chemicals in them.
The outdoor season in Greenville runs late April through early October — about 6 months unheated, with a heater adding several weeks on each end. Winters are mild enough that many owners idle equipment with a partial close instead of a full winterization. The Lowcountry swims from late April into October with subtropical humidity that raises sanitizer demand. The Upstate runs a little shorter and has colder winter nights. Coastal owners also need a hurricane-season equipment and water-care plan.
Upstate Pool Repair has the highest customer rating on this Greenville list at 5 stars across 110 reviews. PoolPad orders the list with a weighted score that combines customer rating and review count, so a long track record counts for more than a handful of scores.
Rarely for the leak itself: wear, tear and gradual damage are excluded from most policies. Sudden events — a pipe burst by a freeze, or damage caused by a covered peril — may be covered along with resulting damage to the deck or house. Keep the detection report and photos; some policies reimburse the detection fee when the resulting repair is covered.
A full detection visit usually takes two to four hours: pressure testing each line, dye testing the shell, listening for underground breaks and, if needed, a diver. Simple repairs at fittings are often done the same day; underground plumbing repairs that require cutting and patching the deck take one to three days including concrete cure.
