the United States 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.
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 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.
Narrow the options to your city, then confirm the scope and the price before anyone comes out.
Companies are ordered by a weighted mix of customer rating and review count; specialists for this work are listed ahead of the companies that routinely handle it.
Review rating, review count and contact details, then ask the questions above so every quote covers the same job.
Share the pool size, equipment and current condition so each company prices the same scope, and compare at least two.
A full leak detection in your area, the United States — 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–$1,200, a light niche seal $250–$900, a structural crack $500–$2,500, and an underground plumbing repair $500–$3,000 depending on how much deck has to be opened. the United States 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 your area during the local swim season, 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.
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.
