Gas Leak Detection in Pontaic is the fastest way to confirm whether that sulfur smell, hissing line, or dead patch of grass is a real gas line leak. Leak Fix Pros runs electronic leak detectors, tracer gas, and pressure testing across Downtown Pontiac and Pontiac Central, then repairs the line the same visit. If you smell gas, call 2487495329 and get out of the house first.
Gas Leak Detection in Pontaic is a diagnostic service that pinpoints escaping natural gas or propane in supply lines, fittings, and appliances before it becomes a fire or health hazard. We pressurize the line, sweep it with an electronic leak detector, confirm with tracer gas where readings are ambiguous, and mark the exact failure point. Most homes we test have a single failed fitting or a pinhole in a copper pipe run, not a whole-system problem. You get a written location, a repair quote, and a clear yes-or-no answer the same day.
Pontiac's housing stock drives most of the calls we run. Century-old homes near Downtown Pontiac still have original black steel gas piping, and the joints on those runs corrode from the inside out. Newer builds with PEX tubing and PVC pipe venting sometimes hide a gas line leak behind finished walls where you can't see or smell it. If you've been searching for gas leak detection in Pontiac Michigan near me at 2 a.m. because the dog won't stop pacing near the furnace, that's exactly the call we take.
Every gas leak detection service Pontiac Michigan call includes the full diagnostic sweep, a written location, and a repair quote. If the leak is accessible and you approve the repair, we fix it the same visit. Here's what's in the standard scope.
We isolate and pressurize the gas line with a calibrated pressure testing kit. A pressure drop confirms a leak; a stable reading clears the run. This is the first test we run and the one that tells us whether we're chasing a real problem.
Every fitting, valve, and appliance connection gets walked with an electronic leak detector. We log readings in parts per million so you can see how strong the leak is at each point, not just where it is.
When readings are ambiguous or the line runs behind finished walls, we introduce tracer gas and re-sweep. This narrows the location to within a few inches, which means smaller access holes and less drywall to patch.
You get a one-page report with the leak location, the test readings, and photos of the failure point. Useful for insurance, home sale inspections, or just knowing what you paid for.
If the leak is at an accessible fitting or pipe run, we quote the repair on the spot. Approve it and we do the work before we leave. No second appointment, no second trip charge.
We ask three questions: where do you smell it, how long has it been happening, and is anyone feeling dizzy or nauseous. If the answer points to an active leak, we tell you to leave the house and call 911 before we dispatch. Otherwise we book you same-day, usually within a two-hour window.
Our tech parks short of the driveway, walks the exterior with a combustible gas meter, and shuts the meter valve if readings are elevated. We vent the structure, then start the interior sweep. This first pass takes 10 to 15 minutes and tells us whether we're dealing with a supply-side or appliance-side leak.
We isolate the gas line and pressurize it with a pressure testing kit. A drop in pressure confirms a leak; a stable reading clears the line. From there we walk every fitting, valve, and appliance connection with an electronic leak detector, then cross-check hot spots with tracer gas.
Once we've got a reading, we narrow it with a pipe locator and, where the line runs under slab, a video pipe inspection camera. We mark the exact spot with paint or tape so you can see it. You get a written location, a photo, and a repair price before we touch a wrench.
We replace the failed section with new copper pipe or approved fittings, seal joints with pipe sealant rated for gas service, and re-pressurize. The line holds pressure for the full test window or we don't call it done. You get the test record and a walkthrough of what we changed.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Reads gas concentration in parts per million at each fitting and valve. Our primary tool for pinpointing leaks on interior runs.
Confirms leak location when readings are ambiguous or the line runs behind finished walls. Narrows the location to within inches.
Shows temperature shifts along a gas run that indicate escaping gas. Useful on underground lines and behind walls.
Traces the path of buried gas lines so we dig at the leak, not at a guess. Cuts excavation time and yard damage.
Pressurizes the isolated gas line and holds it for the test window. A drop confirms a leak; a stable reading clears the line.
Looks inside the line where accessible. Used on slab leaks and underground runs to confirm the failure type before we open anything up.
Battery-powered cutting, fitting, and testing tools so we're not running cords through your home or waiting on an outlet.
A homeowner in Downtown Pontiac smelled sulfur near the water heater for three weeks. Two previous companies told her it was the water heater itself and quoted a replacement. The smell got stronger.
We pressure tested the gas line, found the drop in the section feeding the water heater, and located a failed union with an electronic detector. Replaced the fitting and retested. The line held pressure for the full test window and the smell was gone the same day.
A Pontiac homeowner had a straight line of dead grass across the front yard for two summers. Two lawn companies told him it was grub damage. His gas bill had crept up 30 percent with no usage change.
We pressure tested the underground run, traced it with a RIDGID pipe locator, and dug at the marked point. Found a pinhole in the copper line where it passed under a root. Replaced the section, retested, and backfilled. Gas bill dropped back to normal the next cycle.
A restaurant near Pontiac Central failed a gas line inspection two days before reopening. The inspector flagged a pressure drop on the main run and gave them 48 hours to fix it or stay closed.
We ran an emergency sweep after close of business, isolated the leak to a failed valve on the main run, and replaced it with a new gas-rated valve and fittings. Pressure test passed and we provided the documentation the inspector needed. They reopened on schedule.
Most gas calls fall into a handful of patterns. Here's what we see most often and what happens if you let it ride.
Ask a pro →We sweep the appliance connections with an electronic leak detector, isolate the failed fitting, and replace it with new pipe fittings and gas-rated sealant. Pressure test confirms the fix before we leave.
We pressure test the underground run, use a pipe locator to trace the line, and dig at the marked point. Most underground repairs are a single section replacement with new copper pipe or approved poly.
We shut the valve, replace the failed component, and re-pressurize. If the meter-side fitting is the problem, we coordinate with your utility so the repair is done to their spec.
We run a full pressure test and tracer gas sweep to find the loss. Once located, we repair the section and retest. Most customers see the bill normalize the following cycle.
$180 - $450 for standard residential detection; $280 - $700 with underground or slab work
Typical 2026 pricing for gas leak detection in Pontiac runs $180 to $450 for a standard residential sweep, with underground or slab work adding $100 to $250. Repair is quoted separately once we've located the leak. Emergency after-hours dispatch carries a higher rate, and commercial jobs are quoted per site. We give you the detection price and the repair price before we start, so there's no hourly meter running while we work. If the repair turns out to be more involved than the initial sweep suggested, we stop and requote.
The detection price buys you a documented answer, not a guess. If we find nothing, you know your line is clear and you have the pressure test record to prove it. If we find a leak, you have a location, a photo, and a repair price before anyone touches a wrench.
A single furnace connection is a quick sweep. A full home with a furnace, water heater, range, dryer, and outdoor grill takes longer and adds to the detection price.
Exposed basement runs are fast. Lines behind finished walls or under slab require tracer gas and a video pipe inspection camera, which adds time and cost.
Underground leaks need a pipe locator and excavation. Interior leaks at accessible fittings are the least expensive to find and fix.
Standard business hours are the base rate. Nights, weekends, and holidays carry an emergency dispatch premium because we're pulling a tech off rotation.
Most residential gas leak detection in Pontiac runs $180 to $450 in 2026, depending on how many appliances and how much accessible line we're testing. Add $100 to $250 if the leak is under slab and we need a video pipe inspection camera to locate it. Repair is quoted separately once we know the failure point. Emergency after-hours calls carry a higher dispatch rate.
The four signs we hear most: a sulfur or rotten-egg smell near the furnace or water heater, a hissing sound at a gas valve, dead grass in a straight line across the yard, and headaches or nausea that clear when you leave the house. Any of those means call us or the utility before you flip another switch.
