The Importance of Scheduling a Gas Leak Detection in Milwaukee

A gas leak is one of the most dangerous issues a property can face, yet it’s often hidden. They can lead to fires, explosions, carbon monoxide poisoning, or serious health problems if left undetected.

At Feltner Sewer & Drain, we believe prevention is the best protection. That’s why we offer professional gas leak detection. Our trained technicians use state-of-the-art equipment to identify even the smallest leaks before they escalate.

If you’ve never had your gas lines inspected or if you suspect a leak, now is the time to schedule a check-up.

Warning Signs of a Gas Leak You Should Never Ignore

If you notice any of these warning signs, call a professional right away.

  • A strong rotten egg or sulfur smell in your home or yard
  • Hissing or whistling sounds near gas lines or appliances
  • You’re feeling nauseous, dizzy, fatigued, and have a headache
  • Dead grass, plants, or vegetation near buried gas lines
  • Air bubbles in standing water or mud around your property
  • An unexpected spike in your gas bill

How We Detect Leaks: Advanced Tools, Accurate Results

At Feltner Sewer & Drain, finding residential leaks isn’t guesswork; it’s tried-and-true methods backed by years of experience and specialized training. We combine time-tested techniques with cutting-edge diagnostic tools to give our Milwaukee clients fast, accurate, and non-invasive leak detection.

Combustible Gas Detectors

We use calibrated handheld gas detectors, also known as electronic sniffers, that sense and measure combustible gases at extremely low concentrations. These tools allow us to trace leaks to exact locations, even when behind walls, under floors, or along outdoor lines.

Precision Pressure Testing

For suspected leaks inside piping systems, we perform controlled pressure-drop tests. By isolating sections of the gas line and applying air or inert gas, we can monitor for pressure loss over time, a sure sign of a hidden leak.

Soap Solution Leak Tests

To pinpoint leaks, we use a professional-grade soap solution that forms visible bubbles when applied to leaking joints, valves, or fittings. This method is especially useful in exposed areas or appliance hook-ups.

Thermal Imaging & Infrared Sensors

Using infrared thermography, we can detect subtle temperature changes caused by escaping gas or its impact on nearby materials. This is especially helpful for gas lines hidden behind drywall or in concrete slabs.

Ultrasonic and Acoustic Leak Detection

In more complex or high-pressure systems, we use ultrasonic listening devices to detect the high-frequency sounds that gas makes as it escapes through even the smallest pinhole. This non-invasive method is highly effective on underground or hard-to-access piping.

Had a pipe break in the basement. Called Feltner's and the next day Steve and Andrew came out, fixed the pipe quickly and professionally. Got me in contact with a restoration company that could come out the same day to do a free assessment for the condition of our insulation behind the dry-wall within a few hours. Highly recommend.

At Feltner Sewer & Drain, we’re local, reliable, and ready to help. Explore our current service areas.

Suspect a Leak? Here’s Exactly What to Do Before Help Arrives

Propane and natural gas line leaks can be very dangerous; they are highly flammable and can cause serious health risks. That’s why you should leave the repairs to our licensed gas leak detection plumbers, who know how to handle gas line emergencies safely and effectively.

Call Feltner Sewer & Drain at (866) 335-8637 and follow these steps:

  1. Evacuate the area immediately. Get everyone out of the building as quickly and calmly as possible.
  2. Leave doors and windows open on your way out to help ventilate the space.
  3. Avoid anything that could cause a spark. Do not turn on or off any electrical switches, appliances, or lights. Do not use your phone, lighters, or anything electronic while inside the building. 
  4. If it’s safe to do so, shut off your gas supply at the main valve (usually located near the gas meter). If you’re unsure how, or it’s unsafe, skip this step. Alternatively, call your utility company to request an emergency gas shutoff. 
  5. If the situation appears dangerous, you detect a strong gas odor, or someone isn’t feeling well, call 911 once outside and at a safe distance.
  6. Wait for Feltner’s trained professionals to arrive. We’ll inspect and clear the area before re-entering the property.

FAQs

How do I know if it's safe to stay in my home if there’s a gas leak?

If you suspect a gas leak, the safest choice is to leave immediately. Even if you’re unsure, it’s always better to step outside and call a professional than risk exposure or ignition inside your home.

If you even suspect a gas leak, it’s best to treat it seriously. It’s always safer to call a professional for detection. We’d rather check and find nothing than have you risk your safety.

Most appointments take about 60 to 90 minutes, depending on the complexity of your property.
