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.

Our Gas Leak Detection & Repair Services

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.

Samyson was an absolute superstar - after being without hot water for a few days, he swooped in to save the day (and wouldn't quit when faced with a bit of rust/bolts that refused to budge!) Highly recommended and our dogs loved that he would throw a ball for them anytime he had to go back to his van

I recently had some electrical work done, as well as all of the smoke detectors. Everything went well, then a few weeks later they started going off on the second floor. I called and they sent someone right away. It was a defective alarm. Thank you Landry for sending someone right away.

5 stars to Landry Mechanical. The scheduler got me setup for service next day. I received a text message confirming I was on the schedule the morning of service. Then they sent me photos of the electricians with verified background checks that would be servicing my exhaust fan issue. Mike Dowd and Nick Chappelle were FANTASTIC and resolved my electrical issue and set me up with a new Panasonic bathroom exhaust fan which is much quieter and brighter. Mike and Nick were timely, professional, friendly and very helpful in resolving my problem and answering my questions. Great experience with Landry - thank you!

I had an emergency with my shower pipe coming from behind the wall which corroded at the fittings and it blew the shower head off the wall spewing water everywhere. I turned water off and called Landry. They came immediately the next day and told me via text on arrival time. The technician was absolutely pleasant to talk to and his service was perfection 🥰 I will be calling again for upstairs apartment as soon as possible.
