Plumbing Leak Detection: Ann Arbor, MI
The difference in Ann Arbor leak detection is fit-to-place — parts chosen for the conditions they'll live in. Set in Michigan's continental-climate region — a humid continental climate — hot, humid summers and cold, snowy winters, with sharp freeze-thaw swings between seasons — homes here contend with freeze-thaw cycles that crack pipe and split fittings and deep winter cold that freezes exposed and uninsulated supply lines, 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 Washtenaw County are slow drains from grease that congeals in the cold and sump pumps overwhelmed by seasonal snowmelt, and our leak detection trucks are stocked for them. With 65% 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.
Climate-wise, Ann Arbor belongs to Michigan's continental-climate region, with a humid continental climate — hot, humid summers and cold, snowy winters, with sharp freeze-thaw swings between seasons. For a home's plumbing that means contending with freeze-thaw cycles that crack pipe and split fittings, deep winter cold that freezes exposed and uninsulated supply lines, and summer heat and humidity that strain water heaters and sweat pipes — so we spec corrosion- and freeze-rated pipe, fittings, and equipment to match the local climate.
The pattern across Ann Arbor homes is consistent — slow drains from grease that congeals in the cold, sump pumps overwhelmed by seasonal snowmelt, and failing water heaters strained by cold inlet water. The causes are local: 149 days below freezing a year freeze and split supply lines and outdoor spigots, 59 inches of snow and a long frost season keep buried lines cold enough to crack at the joints, and 65% of local homes predate 1980 (median build year 1971), so many still run original galvanized steel or polybutylene pipe and fixtures well past their service life. That's the wear our Ann Arbor trucks are stocked against, one-visit fixes included.
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 Ann Arbor 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 Washtenaw County.

How to tell you need leak detection
Around Ann Arbor, the tell-tale version is sump pumps overwhelmed by seasonal snowmelt.
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.
Warm spot on the floor
A patch of Ann Arbor 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.
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 Logan.
Root causes we repair with leak detection
Slab leaks
Supply lines run under the concrete slab in many Ann Arbor 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.
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.
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 Washtenaw County.
The Ann Arbor climate factor
Ann Arbor sits in Michigan's continental-climate region, and road salt and groundwater that corrode buried service lines — around here that shows up as slow drains from grease that congeals in the cold. Our local trucks carry parts for exactly that wear.
