A slab leak hides in the water lines buried under your home's concrete foundation. Acoustic listening detects the hiss of pressurized water escaping pipes beneath the slab. Thermal imaging reveals the warm footprint a hot-water leak paints across the floor. Pressure testing isolates which pipe run is losing water. We combine all three to mark the leak's position within inches, without breaking concrete to look. Leesburg homeowners call (352) 703-8206 at the first warm spot or strange sound, and we arrive in 30–45 minutes.
Pressurized water escaping a pipe makes a distinct hiss that travels through concrete. Our sensitive ground microphones sweep the slab and rank every sound by intensity. The loudest point marks the leak, often within inches. This is the star method of slab forensics, and it works without touching the concrete.
A hot-water line leaking under the slab warms the concrete and tile above it. Thermal cameras paint that warmth as a glowing patch on an otherwise cool floor. We map these hot spots room by room, and their shape often traces the leaking pipe's exact path.
We cap and pressurize individual hot and cold runs, then watch which one loses pressure. This test proves which line is leaking before the acoustic gear ever touches the floor. Knowing the exact run narrows the search from the whole house to a single pipe.
Water escaping under a slab often surfaces at the foundation's edge or through expansion joints. We walk the perimeter looking for damp soil, efflorescence, and moisture at the slab line. These exterior clues confirm an interior leak and help aim the listening gear.
Once we find it, we mark the exact spot on the floor and document it with photos and measurements. Your repair plumber gets a target, not a treasure hunt. Precise marking means the smallest possible opening and the fastest possible repair.
A patch of floor that feels warm under bare feet, especially near bathrooms, signals a hot-water line leaking below. The slab conducts the heat upward. Warm spots that never cool down deserve immediate investigation.
You hear water moving inside the floor when nothing is running. That sound is pressurized water escaping a buried pipe. A quiet house at night makes this clue unmistakable.
Slab leaks run twenty-four hours a day, and the meter records every gallon. A sudden, sustained bill increase with no visible leak often means the water is escaping where you cannot see it: under the concrete.
Water under the slab erodes soil and shifts concrete, and the flooring above shows the stress. Cracked tiles, buckling wood, or lifting laminate near plumbing walls can all trace back to a slab leak.
Moisture wicking up through the slab edge dampens carpet, baseboards, and lower drywall. The water travels farther than you expect. Persistent dampness along an exterior wall often starts under the floor.
A hot-side slab leak drains hot water continuously, forcing the heater to run far more than normal. If the heater never rests and the bill climbs, the leak may be hiding in the hot line under your slab.
We interview the symptoms: warm spots, sounds, bill history, and heater behavior. Then we run a meter isolation test to prove the leak is on your side and active. Only when the evidence points under the concrete do we deploy the slab-specific gear.
Ground microphones scan the slab room by room while the system stays pressurized. We mark the loudest points and compare them across multiple passes. Consistent loud spots, not one-off noises, earn the leak's location.
The thermal camera scans floors for the heat signature of a hot-water leak or the cool signature of cold-water evaporation. We overlay the thermal map on the acoustic results. When both methods point to the same square foot, confidence is high.
We mark the leak location on the floor, photograph everything, and write a plain-language report with measurements from fixed reference points. You hand your repair plumber an exact target, which keeps the opening small and the repair fast.
A slab leak terrifies homeowners because the fix sounds like demolition. Our job is to make sure nobody breaks concrete on a guess. Acoustic listening hears the leak, thermal imaging sees its heat, and pressure testing proves which line is guilty. We have spent 19 years refining this three-method cross-check on Florida slabs, and it routinely locates leaks within inches. The result is one small, planned opening instead of a floor torn up on hope.
Speed matters too, because slab leaks never pause. Water under pressure keeps eroding soil and feeding moisture into your home around the clock. We answer 24/7 and we arrive in 30–45 minutes, so the listening starts the same day you call. Leesburg homeowners rate us 4.8/5 from 30 reviews, and many of those reviews describe the relief of watching us mark one small X on the floor instead of tearing up rooms.
A warm patch on tile that persists for days is the classic hot-side slab leak signature. Mark its edges with painter's tape and watch whether it grows. Early acoustic detection at this stage finds the leak while the repair is still small.
Slab leaks are easiest to hear between midnight and dawn, when traffic and appliances go silent. Put your ear to the floor near bathrooms and the water heater. A faint hissing or rushing sound with everything off is worth a professional listen.
A heater that cycles constantly or runs out of hot water faster than it used to may be feeding a hot-line slab leak. Note the change and mention it when you call. Heater behavior is one of the strongest corroborating clues we use.
A repair plan should start from a marked, documented leak location, not a guess. If someone proposes breaking concrete without acoustic or thermal evidence, get a second opinion. Precision now saves thousands in unnecessary demolition later.
Cracked tiles, damp baseboards, and warm spots all evolve. Dated photos show the leak's progression and help your insurer understand the timeline. Bring the photos to our visit; they sharpen the investigation.
If you suspect a slab leak under a room, avoid loading that area with heavy furniture. Extra weight on compromised soil is unhelpful, and clear floor space lets our listening gear and thermal camera work without obstruction.
A slab leak becomes an emergency when water is visibly flooding floors, the water heater runs nonstop, or flooring is buckling across a room. Under-slab water erodes supporting soil and can keep a home's foundation wet for months. Do not wait for the damage to spread. Our emergency slab leak detection in Leesburg FL pinpoints the source without demolition, and we arrive in 30–45 minutes. Learn about our Emergency Slab Leak service in Leesburg, FL.

Three non-invasive methods do the work. Acoustic listening hears the hiss of pressurized water escaping the pipe through the slab. Thermal imaging sees the heat a hot-water leak paints on the floor. Pressure testing proves which pipe run is losing water. Together they triangulate the leak's position, usually within inches, and the concrete stays intact until the repair plumber makes one precise opening.
Through our ground microphones it sounds like a distinct hiss or rushing noise, louder as the sensor nears the break. To the unaided ear, homeowners often describe a faint running-water sound in the floor when everything is off, usually noticed at night. Not every slab leak is audible without equipment, which is why we cross-check sound with thermal imaging and pressure tests.
Persistent warm spots are the classic sign of a hot-water line leaking under the slab. The escaping hot water warms the concrete, and the tile above conducts that heat to your feet. A warm patch that never cools, especially near bathrooms or the water heater, deserves professional investigation promptly, because hot-side leaks waste energy as well as water.
Yes. We answer 24/7 and serve every Leesburg neighborhood, including Downtown, Briarwood, Woodland Hills, Rolling Meadows, Southside, and Bridgewater, plus ZIPs 34748, 34788, 34749, and 34789. Call (352) 703-8206 any time and we arrive in 30–45 minutes with acoustic and thermal gear ready.
Damage starts the day the leak starts and compounds silently. Pressurized water erodes the soil supporting the slab, moisture wicks into flooring and baseboards, and hot-side leaks run the water heater constantly. Because none of this is visible at first, months can pass before symptoms appear. Early detection is the difference between a small repair and a major restoration.
Coverage varies widely by policy, and only your insurer can answer for your home. Many policies distinguish between the cost of finding the leak, accessing it, and repairing resulting damage. We provide dated documentation, photos, and a written report describing what we found, which gives your adjuster the facts needed to evaluate the claim.
Most slab investigations take one to three hours on site, depending on the home's size and how many pipe runs need testing. The acoustic sweep and thermal mapping are the longest steps, because we verify every loud or warm spot with repeat passes. You get the marked location and written report the same visit, with no return trip needed for the diagnosis.
If water is actively flooding or the meter shows heavy continuous flow, shutting off the main valve limits damage and waste. For a suspected slow leak with no visible water, you can leave the system on so our acoustic gear can hear the pressurized hiss. When in doubt, call us first at (352) 703-8206 and we will advise based on your symptoms.
