About this service
What Commercial Leak Detection in Pontaic actually involves
Commercial Leak Detection in Pontaic is the process of finding hidden water, sewer, or gas leaks in a commercial building without tearing the place apart. We start with a full pressure test on the affected line, then use acoustic leak detection equipment and a thermal imaging camera to hear and see where water is escaping. A moisture meter confirms the wet zone, and a video pipe inspection camera checks for root intrusion or cracked PVC. Most buildings get a written location report the same day.
Pontiac's older commercial stock - brick storefronts downtown, mid-century office blocks, and converted industrial spaces - runs on a mix of copper pipe, galvanized steel, and PEX tubing that has been patched for decades. Freeze-thaw cycles from November through March stress those joints, and a slab leak under a restaurant kitchen can run for weeks before anyone notices. That is why business leak detection Pontiac Michigan owners call us most often after a spike in the water bill or a soft spot in the floor.

What's included
What our commercial leak detection service includes
Every commercial leak detection visit includes the diagnostics, the documentation, and a repair plan. Add-ons like gas testing or multi-building surveys are quoted separately so you only pay for what your building needs.
✓
Full pressure testing
We isolate and pressurize the suspect line with a calibrated pressure testing kit. This tells us whether the leak is on the supply side, the drain side, or in a fixture. It is the first step on every job and it takes 20 to 40 minutes.
✓
Thermal and acoustic scan
A Fluke thermal imaging camera shows temperature differences where water is moving behind a wall or under a slab. Acoustic leak detection equipment picks up the sound of escaping water. Together they narrow the search to a 12-inch zone.
✓
Moisture mapping
We take readings with a General Tools moisture meter at multiple points and map the wet zone on a floor plan. This shows how far water has traveled and whether mold risk is present. You get the map in the written report.
✓
Pipe locating and marking
A pipe locator traces the exact path and depth of the leaking line. We mark the spot on the floor or wall so your plumber knows where to cut. This step alone saves most clients hundreds in exploratory demo.
✓
Written leak report
You get a report with photos, thermal images, moisture readings, pipe material, and a recommended repair scope. It is written for a plumber or an insurance adjuster to read. Most reports are delivered the same day as the visit.
How it works
How our leak detection process works
01
Phone intake
You call 248-749-5329 and tell us what you are seeing - high bill, wet floor, gas smell, or a tenant complaint. We ask for the building address, the type of space, and whether the issue is water, sewer, or gas. That call takes about five minutes and lets us load the right gear before we roll.
02
On-site survey
A licensed technician walks the building with you, checks the meter, and maps the suspect lines. We note every fixture, shutoff, and riser. This survey usually takes 20 to 40 minutes depending on square footage and how many units share a meter.
03
Non-invasive testing
We pressurize the line with a pressure testing kit, then sweep the walls and slab with a Fluke thermal imaging camera and an acoustic leak detection unit. For gas, we introduce a tracer gas and read it with a Sewerin detector. Nothing gets opened up at this stage.
04
Pinpoint and mark
Once we hear or see the leak, we mark the exact spot with a pipe locator and confirm depth. You get a photo of the mark and a moisture meter reading so your plumber knows exactly where to cut. Pinpointing typically takes one to three hours on a mid-size commercial building.
05
Report and repair plan
We hand you a written report with the leak location, the likely cause, and a repair scope. If you want us to handle the fix, we quote it on the spot. If you use your own plumber, the report gives them everything they need to do the job right the first time.
Tools & methods
Tools and methods we use on every job
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Acoustic leak detection equipment
Listens for the sound of pressurized water escaping a pipe. Works through concrete, drywall, and tile without opening anything up.
Fluke thermal imaging camera
Shows temperature differences caused by moving water. Used to scan walls, ceilings, and slabs for hidden moisture zones.
Sewerin tracer gas detector
Picks up trace gas introduced into a suspect line. The go-to tool for gas line leaks and hard-to-hear water leaks.
RIDGID video pipe inspection camera
Sends a camera down a drain or sewer line to spot root intrusion, cracked PVC, or offset joints.
General Tools moisture meter
Reads moisture content in drywall, wood, and concrete. Confirms the wet zone and tracks how far water has spread.
Pipe locator
Traces the exact path and depth of a buried or in-slab line so the repair crew cuts in the right spot.
Pressure testing kit
Isolates and pressurizes a line to confirm whether a leak exists and which side of the system it is on.
Real results
Before and after.
Restaurant slab leak stopped in one visit
Before
A Downtown Pontiac restaurant had a water bill that jumped from $620 to $1,480 in one month. The kitchen floor was warm in one spot and a tile had started to lift. Two plumbers had quoted full slab replacement.
After
We pinpointed the leak to a 10-inch section of copper under the dish station in under two hours. The plumber cut one small access point, repaired the line, and the next bill came in at $640.
Office building musty smell resolved
Before
A Pontiac Central property manager had a tenant complaining about a musty smell for six weeks. Two ceiling tiles had been replaced twice. No visible water was found by the building's regular plumber.
After
Acoustic testing traced the leak to a pinhole in a copper riser two floors above the stained tile. The fix took one hour of plumbing work and the tenant complaint stopped within a week.
Warehouse gas leak isolated same night
Before
A warehouse near Pontiac's industrial edge smelled gas near the boiler room on a Friday at 9 p.m. The utility had been called but had not arrived. Operations were on hold.
After
We arrived in 75 minutes, introduced tracer gas, and isolated the leaking joint with a Sewerin detector before the utility showed up. The joint was repaired the same night and the building opened Saturday at 6 a.m.

Tenant reports musty smell or damp drywall
We use a moisture meter to map the wet zone and a thermal camera to trace the source. You get a documented report that supports both the repair and any tenant communication you need to send.
Gas odor near a boiler or kitchen line
We respond 24/7 with a tracer gas leak detector and Sewerin equipment, isolate the bad section, and document the reading for the utility and your insurer. Most gas calls are pinpointed within 90 minutes of arrival.
Warm spots or cracked tile on a slab floor
Acoustic detection and thermal imaging locate the break to within a foot. Your plumber cuts one small access point instead of breaking up the whole slab, saving thousands in concrete and finish work.
Transparent pricing
Commercial leak detection pricing in Pontiac
$249 - $850 depending on building size and number of lines tested
Commercial leak detection in Pontiac runs $249 to $850 in 2026 for most buildings. A single-line survey on a small office or retail space starts at $249. A multi-line job with water and gas testing on a larger commercial property lands in the $500 to $850 range. Emergency after-hours calls carry a modest surcharge. You get the detection price quoted before we start, and the report is included. If you want us to handle the repair too, we quote that separately so you can compare.
One undetected slab leak can add $400 to $1,200 a month to a Pontiac commercial water bill. A detection visit costs less than one month of that loss, and it prevents the concrete and finish damage that turns a $400 repair into a $6,000 one.
01Building square footage
Larger buildings take longer to survey and may have multiple zones to test. A 2,000 sq ft office is a one-hour job. A 20,000 sq ft warehouse can take three to four hours.
02Number of suspect lines
Testing one supply line is fast. Testing water, gas, and drain lines in the same visit adds time and equipment. We quote per line so you can prioritize.
03Access difficulty
Lines behind finished walls, under slabs, or in tight chases take longer to scan. We tell you upfront if access will affect the price.
04After-hours or emergency timing
We run 24/7, but emergency dispatch outside normal hours carries a surcharge. Most Pontiac clients find the surcharge is far less than a day of lost business.

The four most common signs are a water bill that jumped 20 percent or more, damp or stained ceiling tiles, a musty smell in one zone, and warm spots on a slab floor. In Pontiac restaurants we also see warped kitchen flooring and constantly running meters. Any one of those is worth a detection visit.
Yes. We run 24/7 commercial leak detection Pontiac open now coverage for active flooding, gas line leaks, and supply breaks that are shutting down a business. Call 248-749-5329 any hour and we dispatch. Emergency arrival inside Pontiac is usually under 90 minutes.
Once a year is the right cadence for most Pontiac commercial buildings, ideally in early fall before the freeze season starts. Buildings over 40 years old, restaurants, and any property with a history of slab leaks should go every six months. A yearly check costs far less than one undetected leak.
