Plumbing Leak Detection in Rhode Island
A hidden leak can waste thousands of gallons and hundreds of dollars before it ever shows a stain, and by the time it does the damage is already done. Leak detection is the diagnostic step that finds water escaping inside a wall, under a slab, or below the yard — precisely — so the repair opens one small area instead of chasing the leak through half the house. We combine acoustic listening equipment, thermal imaging, moisture metering, and system pressure testing to locate the source without guesswork or demolition.
The tools each read a different signature. Acoustic sensors amplify the hiss of pressurized water escaping a pinhole, which we trace to the loudest point over a slab or wall. Thermal cameras see the temperature difference a hot-water slab leak leaves on the floor. A pressure test isolates supply from drain — if the system holds pressure with the water off, the leak is on the drain side; if it bleeds down, it's a supply line. Putting the three together turns a mystery water bill into a marked spot on the floor.
Not every leak announces itself with a puddle. A spinning water meter with every fixture off, a warm patch on a {city} floor, a musty smell with no visible source, or a foundation crack that stays damp all point to water escaping where you can't see it. We locate it, mark it, photograph the reading, and hand you a repair quote for exactly that section — and if the leak turns out to be a simple fixture or a running toilet, we'll tell you that too before anyone opens a wall across {county}.
Signs you need leak detection
Water bill jumped with no change in use
A bill that climbs while your habits stay the same is water escaping somewhere unseen. A leak-detection visit finds where before the waste compounds another month.
Sound of running water with everything off
A faint hiss or trickle in the walls when no tap is open is pressurized water escaping a hidden line. We trace the sound acoustically to its exact source.
Warm spot on the floor
A patch of the United States floor that's warm underfoot usually means a hot-water line is leaking under the slab. Thermal imaging confirms it without breaking concrete to look.
Musty smell or unexplained mildew
A persistent damp or moldy odor with no visible leak means water is feeding mildew inside a wall or cabinet. Moisture metering finds the wet cavity.
Meter dial spins with no water running
Shut every fixture, watch the meter — if it still creeps, you have a leak on the pressurized side. It's the simplest confirmation that a hidden leak exists, and our cue to locate it across your area.
Common causes & what we fix
Slab leaks
Supply lines run under the concrete slab in many the United States homes, and a pinhole there leaks straight into the foundation. Acoustic and thermal locating pinpoints it so only a small area is opened.
Pinhole leaks inside walls
Copper pitted by aggressive water weeps behind drywall long before it stains. Catching it at the detection stage keeps the repair small.
Underground supply-line failures
The buried line from the meter to the house corrodes or gets crushed by roots and settling, leaking into the yard. We trace it above ground before digging.
Failed fittings and connections
Solder joints, compression fittings, and valve bodies weep at the connection first. Pinpointing the exact fitting avoids opening a whole wall run around the United States.
Drain and sewer leaks
Not every hidden leak is pressurized — a cracked drain line leaks only when a fixture runs. Isolating supply from drain by pressure test tells us which system to chase.
