Pool Leak Detection & Repair Cost in Reno & Sparks
As of September 2026, inground pool leak detection typically costs $400-$1000, and repair runs $500-$1500+ depending on where the leak is. Reno Pool Repair Pro doesn't do leak detection ourselves — we match you with an independent, NSCB-licensed contractor who has the equipment to actually find it.

That liner-replacement range above is a national benchmark. The closest thing we've found to a genuine Reno/Sparks-specific figure is a ZIP-tagged estimate (89510 Reno / 89431 Sparks) from ProMatcher, a syndicated cost-aggregator — not a named local contractor's real quote, and dated late 2020 — putting a 16'x32' vinyl liner replacement at $2324.29-$2901.57 as a fixed fee, below the national range shown above. Treat both as starting points, not a quote.
How to tell if you actually have a leak
Evaporation alone can account for a quarter-inch to half an inch of water loss per day, more in Reno's dry summer heat and wind. Before assuming a leak: mark the water line with tape, turn the pump off, and compare the drop over 24 hours against a bucket of water left at the same depth nearby (this controls for evaporation). Water loss clearly beyond the bucket's, wet spots in the yard, a damp equipment pad, or a pool that only loses water while the pump is running (pointing to a pressure-side leak) are the signs worth having checked.
What a leak-detection visit actually involves
We don't perform this work ourselves — an independent contractor typically starts with a pressure test on the plumbing lines, dye testing at suspect spots (skimmers, returns, lights, visible cracks), and for harder cases, electronic listening equipment to pinpoint an underground leak without unnecessary digging. Above-ground leaks (visible cracks, fitting failures, equipment-pad connections) are usually diagnosed faster and cheaper than a hidden underground or shell leak.
What drives the price
- Where the leak is. A visible fitting or skimmer leak is far cheaper to find and fix than one in underground plumbing or the pool's shell/liner.
- How hard it is to locate. A leak that shows up clearly under dye testing costs less to diagnose than one that needs electronic listening equipment or exploratory digging.
- Scope of the fix. A patch or fitting replacement is inexpensive; a liner replacement or a repair requiring excavation is a different cost tier entirely.
Before you hire
Ask for an NSCB license number and verify it yourself at https://app.nvcontractorsboard.com — leak diagnosis and repair falls under Classification A-10e (Maintenance and Repair of Pools and Spas). Not sure your symptom is actually a leak? Check pump & filter repair if the water loss only happens while running, or see the full cost hub.
