Plumbing Leak Detection — New Glarus, WI
What makes leak detection last in New Glarus is local knowledge — the climate, the water, the housing stock. Set in Wisconsin's cold northern climate — a cold northern climate of long, snowy winters, deep sub-freezing cold, and short, warm summers — homes here contend with deep sub-freezing cold that freezes and bursts supply lines and a long frost season that keeps buried pipe cold enough to crack, so we spec corrosion- and climate-rated pipe, fittings, and fixtures rather than whatever's cheapest on the shelf. The failures we see most around Green County are sewer lines sheared by frost heave and frozen exterior spigots through much of winter, and our leak detection trucks are stocked for them. With 70% of local homes built before 1980, original galvanized pipe and aging fixtures past their service life are common — we size every fix to the system in front of us.
The setting for New Glarus is Wisconsin's cold northern climate — a cold northern climate of long, snowy winters, deep sub-freezing cold, and short, warm summers. That load lands on plumbing as deep sub-freezing cold that freezes and bursts supply lines, a long frost season that keeps buried pipe cold enough to crack, and frozen exterior spigots and hose bibs through much of winter — we answer it with corrosion- and freeze-rated pipe, fittings, and water heaters.
Our New Glarus call log is dominated by sewer lines sheared by frost heave, frozen exterior spigots through much of winter, and split pipe and cracked fittings from freeze-thaw. It's not random — 152 days below freezing a year freeze and split supply lines and outdoor spigots, 52 inches of snow and a long frost season keep buried lines cold enough to crack at the joints, 70% of local homes predate 1980 (median build year 1958), so many still run original galvanized steel or polybutylene pipe and fixtures well past their service life, and 69% are detached houses with their own service lateral, water heater, and outdoor spigots to maintain. That's the exact wear and corrosion our New Glarus trucks carry parts for, fixed in a single visit.
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 New Glarus 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 Green County.

Symptoms that call for leak detection
In New Glarus, this most often shows up as frozen exterior spigots through much of winter.
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.
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 New Glarus.
Warm spot on the floor
A patch of New Glarus 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.
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.
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.
Common causes & what we fix
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.
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 Green County.
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.
Slab leaks
Supply lines run under the concrete slab in many New Glarus homes, and a pinhole there leaks straight into the foundation. Acoustic and thermal locating pinpoints it so only a small area is opened.
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.
Local climate wear in New Glarus
Local context matters: in Wisconsin's cold northern climate, seasonal snowmelt that floods basements and strains sump pumps, which is why sewer lines sheared by frost heave top the New Glarus call log. We stock for it.
