About this service

What Water Leak Detection in Pontaic actually involves

Water Leak Detection in Pontaic is the process of locating water escaping from supply lines, drains, or fixtures using acoustic listening equipment, thermal imaging cameras, and pressure testing kits, rather than opening walls and floors on a hunch. We start by isolating the system, pressurize it, and listen for the signature hiss of a pinhole in copper pipe or the steady drip behind a PEX tubing run. A moisture meter confirms the wet zone, and a video pipe inspection camera or pipe locator maps exactly where the break sits before we cut anything.

Pontiac homes and commercial buildings deal with a specific mix of leak problems. The city's older housing stock still runs a lot of original copper pipe that has been stressed by decades of freeze-thaw cycles, while newer builds use PEX tubing and PVC pipe that fail at fittings and joints. When you search for water leak detection in Pontiac Michigan near me at 2 a.m. because you hear water under the slab, we answer. We also handle the underground water leak detection Pontiac property owners need when the meter spins with every fixture shut off.

What's included

What our Water Leak Detection service includes

Every detection call includes the full diagnostic package, not just a listening pass. Here is what is covered in the base price and what we quote separately once we know what failed.

✓

Full system pressure test

We isolate the supply side from the drain side and pressurize each section with a pressure testing kit. This tells us which side of the system is leaking before we start scanning, which saves 20 to 30 minutes of guesswork on every call.

✓

Acoustic and thermal scan

Acoustic leak detection equipment walks the line for the hiss of a pinhole, and a thermal imaging camera confirms the wet zone behind walls or under slabs. Two independent confirmations before we mark a spot for access.

✓

Moisture mapping

A moisture meter maps how far the saturation has spread from the leak point. This matters for insurance claims and for knowing whether drywall, insulation, or subfloor needs to come out in addition to the pipe repair.

✓

Video pipe inspection

For drain-side leaks we run a video pipe inspection camera through the cleanout to see root intrusion, cracked joints, or bellies in the line directly. You see the footage on the monitor with us, so there is no mystery about what we found.

✓

Written findings and repair quote

You get a written summary of what failed, where it is, and what it takes to fix it, with photos attached. The repair quote is itemized so you can see parts, labor, and access work as separate lines before you approve anything.

How it works

How our leak detection process runs

01

Phone triage

You call 248-749-5329 and describe what you are seeing: a spinning meter, a warm floor, a stain on the ceiling, or water pooling near the water heater. We ask four or five questions, tell you what it sounds like, and give you a two-hour arrival window. Most calls in Pontiac get a same-day slot.

02

System isolation

On arrival we shut off the main, drain the lines, and isolate the supply side from the drain side. This takes 15 to 25 minutes and tells us whether the leak is on a pressurized line or a waste line, which changes every tool we reach for next.

03

Pressure and acoustic testing

We pressurize the isolated section with a pressure testing kit and walk the line with acoustic leak detection equipment. A pinhole in copper pipe makes a distinct high-frequency hiss that the microphone picks up through concrete. This step usually runs 30 to 45 minutes.

04

Thermal and video confirmation

A thermal imaging camera shows the temperature delta where water is moving behind a wall or under a slab. If the leak is in a drain line, we run a video pipe inspection camera through the cleanout to see root intrusion or a cracked joint directly. Two tools, two confirmations, one answer.

05

Repair and pressure test

We mark the spot, make the access cut, and repair the line with new copper pipe, PEX tubing, or a proper pipe fitting and solder joint. Then we re-pressurize the system and hold it for 30 minutes. If the gauge moves, we are not done. You get photos of the repair and the final pressure reading.

Tools & methods

Tools and methods we use to find leaks

Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.

Acoustic leak detection equipment

Picks up the high-frequency hiss of a pinhole in copper pipe or a pressurized PEX tubing line through concrete, drywall, and soil. Our primary locating tool on every call.

Thermal imaging camera (Fluke)

Shows the temperature delta where water is moving behind a wall or under a slab. Confirms the acoustic hit and shows how far the wet zone spreads, which guides the access cut.

Pressure testing kit

Pressurizes an isolated section of the system so we can watch the gauge for a drop. Tells us which side of the system is leaking before we start scanning.

Video pipe inspection camera (RIDGID)

Runs through the cleanout to show root intrusion, cracked joints, and bellies in drain lines directly on the monitor. Essential for any drain-side leak.

Moisture meter (General Tools)

Maps how far saturation has spread from the leak point. The readings go into your insurance documentation and tell us what else needs to come out.

Pipe locator and tracer gas leak detector (Sewerin)

Maps the exact run of underground and in-slab lines and confirms leaks in low-pressure systems where acoustic listening alone is not enough.

Real results

Before and after.

Slab leak under a Pontiac Central kitchen

Before

A homeowner in Pontiac Central had a water bill that jumped from $72 to $310 in one cycle. The floor near the kitchen was warm to the touch and the meter spun with every fixture off. Two other companies had quoted full floor replacement to find the leak.

After

We located the break in a hot water line under the slab in 40 minutes using acoustic equipment and thermal imaging. One 14-inch access cut, a new copper pipe section, and a 30-minute pressure hold. The next water bill came in at $68.

Underground service line leak in Downtown Pontiac

Before

A Downtown Pontiac property owner noticed a wet patch in the yard that never dried and a meter that kept ticking overnight. The service line ran 60 feet from the curb to the house, and the leak was somewhere in that run with no visible break.

After

Our pipe locator mapped the line and acoustic equipment found the break at the 38-foot mark. We excavated one 3-foot section, replaced the failed pipe fitting and a 4-foot run of copper pipe, and pressure-tested the line at 80 psi for 30 minutes with no drop.

Toilet leak flange in a North Hill rental

Before

A North Hill rental had a musty smell in a closet and a stain spreading on the ceiling below the bathroom. The tenant had not reported anything because there was no visible water on the floor. Moisture meter readings showed saturation 4 feet from the toilet base.

After

We found a failed toilet leak flange that had been running slowly for months. We replaced the flange, re-seated the toilet with a new wax ring, and documented the moisture spread with photos for the owner's insurance claim. The drywall and subfloor repair was covered.

01

Water bill doubled with no visible leak

We isolate the supply line, pressurize it, and walk it with acoustic leak detection equipment until we hear the break. Most hidden leaks are located in under an hour, and we repair the line the same visit with new copper pipe or PEX tubing.

↗
02

Warm spot on the floor near the bathroom

Our thermal imaging camera confirms the temperature delta, and the pipe locator maps the exact run. We make one access cut, repair the line, and pressure-test it for 30 minutes before closing up.

↗
03

Musty smell and peeling paint on a wall

We scan the wall with thermal imaging and confirm with a moisture meter. Once we find the source, we repair the pipe fitting or solder joint and give you a written scope for the drywall and insulation repair so nothing gets missed.

↗
04

Water heater leaking before a holiday

We shut the unit down, confirm whether the leak is the tank, the T&P valve, or a fitting, and give you a straight answer on repair versus replacement. If it is a fitting or valve we fix it on the spot and pressure-test the line.

What Water Leak Detection costs in Pontaic

$189 - $850 depending on scope and access

Detection pricing in Pontiac for 2026 runs $189 to $450 for most residential calls, and $350 to $850 for commercial or long underground runs. The detection price is flat and quoted before we start. The repair is quoted separately once we know what failed, with parts, labor, and access work itemized on one page. We do not run an hourly meter while we think about it, and we do not pad the repair quote because we already found the leak. If the detection leads to a repair you approve, we credit a portion of the detection fee toward the repair on most jobs.

A hidden leak wastes 10,000 gallons a month and can undermine a slab or feed mold in 48 hours. Detection at $189 to $450 is the cheapest part of the job. Finding it fast is what keeps the repair small and the insurance claim clean.

01Access difficulty

A leak behind an open basement wall takes less time than one under a finished slab or behind tile. Access difficulty is the single biggest driver of detection time, and we tell you which category your job falls into on the phone.

03Number of suspect zones

A single bathroom with one wet wall is a quick scan. A whole-house search with three or four possible leak points takes longer and costs more, but we tell you the zone count before we start.

04Repair material and scope

A pipe fitting replacement on copper pipe is a different job than a 4-foot PEX tubing run or a slab access cut. The repair quote reflects the actual material and labor, not a flat rate that overcharges small jobs.

Frequently Asked Questions

2487495329 →

Most residential detection calls in Pontiac run $189 to $450 in 2026, depending on whether we are scanning a single wall or the whole slab. Underground water leak detection Pontiac jobs on long service lines sit at the higher end because they take longer to isolate. The repair is quoted separately once we know what failed. You get the detection price before we start.

The five we see most: a water bill that jumps 30 percent or more with no change in use, a warm spot on a slab floor, the sound of running water when every fixture is off, a musty smell near a baseboard, and a meter that keeps spinning after you shut the main. Any one of those is worth a call. Two or more means stop waiting.

Yes. Acoustic leak detection equipment hears a pinhole through 4 inches of concrete, and a thermal imaging camera shows the temperature difference where water is moving behind drywall. For drain-side leaks we run a video pipe inspection camera through the cleanout. Between those three tools we locate hidden leaks in walls, under slabs, and underground without exploratory demolition.

Most Pontiac homeowner policies cover the resulting water damage and the access needed to reach the leak, and many cover the detection itself when it is part of a covered loss. The pipe repair is sometimes excluded as maintenance. We document everything with photos and meter readings so your adjuster has what they need to decide quickly.
