Signs You May Have a Gas Leak

Knowing what to look for can help you act quickly and protect your family. Gas leaks often start small and can be difficult to detect without the right tools, but there are several warning signs to watch for.

  • A strong smell of rotten eggs or sulfur
  • Hissing or whistling sounds near gas lines or appliances
  • Dead or discolored vegetation around outdoor gas lines
  • Unexplained dizziness, fatigue, or nausea indoors
  • Higher-than-normal utility bills without increased use

If you notice any of these warning signs, leave your home immediately, avoid using electronics or open flames, and call for professional help.

At Landry Mechanical, we provide complete gas line solutions designed to protect your home, ensure safety, and restore proper system performance. Our licensed technicians are trained to detect and repair leaks quickly using proven methods and advanced diagnostic tools. Every service we perform meets local codes and industry standards, giving homeowners confidence that their gas system is operating safely and efficiently.

Gas Leak Detection

We use state-of-the-art detection technology, including pressure testing and gas sensors, to locate even the smallest leaks in your system. Our technicians carefully inspect your lines, appliances, and connections to pinpoint the exact source of the problem. Once identified, we explain your repair options clearly and make precise, lasting fixes to prevent future risks.

Gas Line Repair

If your gas line shows signs of corrosion, cracking, or leaks, our experts can perform detailed repairs that restore your system to safe working order. We replace worn components, reseal joints, and verify that each connection is secure. After repairs are complete, we perform additional testing to confirm that your gas line is fully sealed and compliant with safety regulations.

Gas Line Installation and Replacement

When a gas line is too damaged for repair, we install a new system built for durability and safety. Our technicians use high-quality piping materials and follow strict installation procedures to ensure reliable operation for years to come. Each new line is thoroughly tested for proper pressure and performance before we restore service to your home.

Preventative Gas Line Maintenance

Routine maintenance is essential for keeping your gas system safe and efficient year-round. Our preventative services include inspecting connections, testing valves, and identifying early signs of wear before they become hazards. By scheduling regular maintenance, homeowners can avoid costly repairs and enjoy peace of mind knowing their system is being professionally monitored.

I needed a repeat for a light fixture install that went bad and took out power to my garage. Mike and Josh showed up first thing in the morning and immediately spotted the issue and restored power, installed the light fixtures and also replaced a transformer for a video doorbell. All the work was clearly explained and done quickly and cleanly. So, I was very pleased with the experience and the electricians and will be calling Landry again next time I need some work done!

Mr. Humphrey sorted out the problem quickly - out of propane. So, I got on to the dealer quickly. I was glad the tankless water heater unit was fine. The unit was less than a year old so still under warranty.
