Pool leak detection cost
Pool leak detection: what it costs and why it comes first.
A full leak detection has three parts: equipment inspected under pressure, the structure inspected in the water with dye testing, and a plumbing pressure test. Our founder charged $275/hour with a two-hour minimum; flat-rate peers run around $500 for a single-pump pool plus $175–200 per additional pump.

Tell the app if you suspect a leak
Leak concerns change the remodel path before the price conversation.
PoolSavr routes leak and crack concerns toward contractor review first, because drainage and new tile should not start on top of an unknown leak.

Why it comes first.
Before anyone drains your pool, get a full leak detection — with the water still in it. I tell every homeowner the same thing: it’s insurance for both of you. If there’s a pipe leaking under your deck, you want to know before you budget that money to new tile — an underground line repair runs $2,000–7,000, and that’s the water feature you were saving for.
And if your pool gets a documented clean bill of health and it’s leaking after the remodel, there’s no argument about whose problem it is: the contractor broke something, and a good one owns it and fixes it at no cost. Mistakes happen in construction. What separates good contractors from shady ones is what happens next.
A full leak detection has three parts: the equipment inspected visually under pressure, every square inch of the structure inspected in the water with anything suspicious dye-tested, and a pressure test of the plumbing.
Full detection
A pressure test alone is not the whole job.
Equipment, under pressure
Every union, pump lid, filter mechanism, and valve is inspected visually while the system runs.
Structure, in the water
A technician gets in the pool and dye-tests suspicious cracks, fittings, lights, and skimmer mouths.
Plumbing, isolated
Lines are pressurized. If pressure drops, the detector pinpoints where before the remodel money moves.

When to test again.
After any plumbing work, always. An isolated section tests quickly, and it is the difference between saying it was fixed and proving it was fixed.

If we have leak-detection professionals in your area, we will have one reach out. We also recommend finding one yourself or asking your contractor, who may offer it in-house. A documented result is what matters.
FAQs
Leak detection questions.
How long does a leak detection take?
A thorough single-pump residential job typically fits a two-hour window. Extra pumps, water features, and spas add time. Beware anyone done in twenty minutes.
Is dye testing reliable?
Yes. It is the standard for distinguishing a surface blemish from a structural crack moving water, and it only works with water in the pool.
My autofill runs constantly. Is that a leak?
It is the most common way homeowners discover one. An autofill hides a leak by feeding it; when it runs more than it used to, something is drinking the difference.
Do I need this if the pool seems fine?
Before a remodel, yes. A clean bill of health protects your budget going in and settles responsibility coming out.
National averages can’t price your pool. They don’t know its size.
