Pool leak detection and gunite structural repair across the WNC mountains — dye testing, plumbing pressure testing, and acoustic leak detection to find where your pool loses water, then crack injection, spall and rebar repair, and skimmer, return, and main-drain fixes. We diagnose first and repair to ANSI/APSP/ICC-5 standards, so you never pay for a rebuild a sound shell doesn't need.

Pool leak detection is the systematic process of finding exactly where an in-ground pool loses water — and structural repair is fixing the shell, plumbing, and fittings once the source is known. The two go together because a leak that's ignored almost never stays cosmetic. Water escaping a gunite shell tracks down to the steel reinforcing grid, and once that rebar starts to rust it expands, spalls the surrounding concrete, and turns a $500 fitting fix into a structural repair. The goal of detection is to catch the loss while it's still cheap.
You need detection when the numbers stop adding up. The classic signs in Western North Carolina are a water level that drops more than 1/4 inch per day beyond normal evaporation, an auto-fill that runs constantly, soggy or sinking ground near the equipment pad or deck, air bubbling back through the returns, or an unexplained jump in your water and chemical bills. Some owners notice it as a pool that's fine all winter but drops fast once the pump runs daily — a tell-tale sign of a pressure-side plumbing leak rather than the shell. Whatever the symptom, the first move is always a bucket test to confirm a real leak before spending a dollar chasing it.
The other trigger is visible damage: a crack in the shell or coping, drummy (hollow-sounding) spots when the plaster is tapped, or rust stains bleeding up through the finish. Those point to cracks and structural concerns rather than a simple fitting leak, and the diagnosis — cosmetic surface check versus a true structural crack — drives everything about the cost and the fix. Most of the gunite pools we see across Hendersonville, Asheville, and the surrounding counties were built decades ago on shifting clay slopes, so a measure of cracking is normal; the skill is telling the harmless from the serious.
Detection matters even more on a transaction timeline. A pool inspection before buying or selling a home routinely flags water loss, and an unaddressed leak can stall a closing or knock thousands off a price. Catching and documenting it early — with a clear scope of what's wrong and what it costs — protects the deal and the shell at the same time.
Every figure below is an installed 2026 range for the Western North Carolina mountains, by repair tier. Detection is a flat service call; repairs are priced once the source is known. Most owners spend the least possible because the bucket test and dye test resolve the majority of leaks before any concrete is opened.
Ranges reflect 2026 installed pricing for the WNC region and are calibrated to the ANSI/APSP/ICC-5 residential-inground standard, ASTM pool-plumbing pressure-testing practice, ACI gunite repair practice, and VGBA anti-entrapment requirements for any main-drain rework. Your actual cost depends on the leak's location, access, and how much deck or shell must be opened — see the resurfacing cost calculator if a repair turns into a resurface.
Before anyone gets paid to dig, we confirm there is actually a leak. A bucket test brackets normal evaporation (about 1/4 inch per day in WNC summers) against your real loss. If the auto-fill is running constantly or you're losing 1/2 inch or more a day, we move to detection. This single step saves owners hundreds of dollars chasing a leak that turns out to be a hot, dry July.
With the pump off, we run phenol-red dye along the waterline tile, behind the skimmer throat, around return fittings, the main drain, and any light niche, watching for the dye to draw into a crack or fitting gap. Drummy (hollow-sounding) plaster is sounded out by hand. This locates the obvious shell and fitting leaks that account for a large share of WNC pool water loss.
Suspected plumbing leaks are isolated with pressure-test plugs and a rig per ASTM pool-plumbing practice — each suction, return, and main-drain line is sealed and pressurized separately so a line that won't hold pressure is identified without guesswork. Main-drain and sump work is brought into VGBA anti-entrapment compliance during any rework, which matters most on HOA and commercial pools.
When a pressurized line is losing water underground, we pinpoint the break with LeakTronics acoustic equipment and a geophone/listening disc before opening any concrete or deck — so the excavation is a small surgical cut, not a torn-out patio. This is the difference between a $600 line repair and a deck demolition.
Fixes are matched to the failure: hydraulic cement (Quikrete) and epoxy/polyurethane injection for cracks, two-part Pool Putty for underwater fitting seals, a Hayward SP1056 hydrostatic relief valve where ground water is the culprit, and PVC line repair for plumbing breaks. Cosmetic cracks are patched and feathered so they disappear under a new finish.
True structural cracks are addressed with rust-converter on exposed rebar, fresh rebar and gunite/shotcrete per ACI repair practice, and staple/stitch reinforcement across the crack — all to ANSI/APSP/ICC-5 residential-inground standards. We then bond-coat and resurface the affected area and run a controlled NPC-method start-up so the repair is invisible and the new plaster cures correctly.
Our process is built to diagnose before we dig. Each step narrows the source from "the pool loses water" to "this fitting, this line, or this crack," so the repair is surgical and the bill is honest. The same six phases apply whether it's a hairline shell check on a Brevard residential pool or a main-drain leak on an HOA community pool — the difference is scale, not method.
If your pool is actively draining or the shell is already exposed, that timeline compresses. Call (828) 555-0142 for same-day triage — getting water back over exposed rebar quickly is the single best thing you can do to stop a cheap leak from becoming an expensive structural one.
Dye testing is the workhorse for shell and fitting leaks. With the pump off and the water still, phenol-red dye released next to a suspected crack, skimmer throat, return, or light niche will visibly draw into the gap — a direct, no-guess confirmation that costs nothing but patience. Pressure testing handles the plumbing: each suction, return, and main-drain line is isolated with test plugs and pressurized separately, so a line that won't hold pressure is identified without opening a single foot of deck. Acoustic and electronic detection (LeakTronics geophone and listening discs) then pinpoints where a pressurized underground line is actually broken, turning a potential patio demolition into a small surgical cut. Together these three methods locate the overwhelming majority of leaks on a residential gunite pool.
The repair materials are matched to the failure, not sold from a catalog. Cosmetic and hairline cracks get hydraulic cement (Quikrete) and epoxy or polyurethane injection; underwater fitting and skimmer seals get two-part Pool Putty epoxy; and where ground water is forcing its way in, a Hayward SP1056 hydrostatic relief valve is set in the main drain so pressure can equalize instead of cracking the shell. True structural cracks are reinforced with fresh rebar and gunite/shotcrete and staple-stitch ties across the crack, with rust-converter applied to any exposed steel first. Once the structure is sound we bond-coat and resurface the area so the repair vanishes under new plaster, quartz, or pebble.
Because so many leaks travel up the waterline and behind the tile band, leak repair frequently overlaps with tile and coping replacement — frost-cracked grout and loose coping are both leak paths and freeze-thaw casualties in the mountains. When the diagnosis reveals an aging shell with several issues at once, it's usually smarter to fold the repair into a planned full remodel and pay for one drain-down and one start-up instead of several. We make that call with you after detection, with the numbers in front of you — and we follow PHTA water-balance guidance on the refill so a fresh repair isn't etched by aggressive start-up chemistry.
Expansive clay and slope. The soils under most pools in Henderson, Buncombe, and Transylvania counties are clay-heavy and built into hillsides. Clay swells when saturated and shrinks in drought, and that constant flex works on the rigid gunite shell and the PVC plumbing buried alongside it until a fitting pulls loose or a crack opens at a stress point — typically a corner, a step, or a penetration. On the steep, terraced lots common around South Asheville and Tryon, ongoing settlement adds movement at the deck-to-shell joint, the most common spot for a slow waterline leak.
Freeze-thaw. Elevation is the multiplier. Hendersonville sits near 2,200 ft and Waynesville above 2,600 ft, and both see dozens of nights below freezing each winter. Water that has seeped into a hairline crack, behind a tile, or under loose coping freezes, expands roughly 9%, and pries the gap a little wider with every cycle — the reason a crack that was cosmetic in October is a leak by April. Frost-rated tile, dense coping, and properly sealed expansion joints are not optional details here; skimping on them is the single most expensive mistake mountain pool owners make, and it shows up first as a leak.
Access and water table. Many WNC pools sit where a leak repair can't be reached by machine, so excavation for a buried line is slow and deliberate — another reason acoustic pinpointing pays for itself. And lakeside or low-lying properties around Lake Lure and Lake Toxaway often carry a high seasonal water table, which makes a hydrostatic relief valve essential: drain such a pool for repair without one and ground-water pressure can literally float or crack the shell. We account for all of it before quoting, and for community and commercial pools we bring main-drain work into compliance with NC public-pool rules (15A NCAC 18A .2500) and VGBA anti-entrapment requirements as part of the repair.
