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.

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.

Frequently Asked Questions

Hear From Our Satisfied Customers

Landry has been looking after my HVAC system for a couple of years now and I have been very happy with their work. The expertise of the technicians is evident, they are always thorough and effective in their work. If the occasion arises they will go the extra mile--for example recently hard wiring my thermostat so I don't need to worry about batteries. As a bonus, I have found them all to be just nice people to have in my house.

The LAST time Landry was here, it was to replace another pipe elbow and a bit more. The technician replaced that OK. However. What the technician DID NOT do fine was turn off the water beforehand. Instead of turning off the water to only my townhouse, he turned off the water to my entire building. This is very bad, because it can mess up the water and pipes for the other tenants in my building. He guessed on the valve. What he should’ve done was ask me which valve it was, instead of guessing. I am NOT happy. The job was ok.

Five Stars -- Landry Mechanical Delivered from Start to Finish When our heating and cooling system gave out, we needed a company we could trust to move fast, communicate clearly, and get the job done right. Landry Mechanical checked every box. From the initial diagnostic visit on our failed system to the completed installation of our new heat pump, the turnaround was remarkably quick. There was no waiting around for weeks wondering what came next. They assessed the situation, quoted the job professionally, and worked with us to design the right system for our home and our family's needs. The quote itself was straightforward and thorough -- no guesswork, no surprises. The install team was outstanding. They worked cleanly, moved efficiently, and left the job fully complete. This was not a crew that cuts corners or leaves loose ends. Every phase of the project felt organized and deliberate. What really stood out was their communication. Before anyone showed up at our door, we received clear notice of who would be arriving and when. Every update along the way was prompt, professional, and easy to understand. In an industry where homeowners often feel left in the dark, Landry Mechanical kept us fully informed throughout the entire process. Perhaps the simplest testament to their reliability: they said they would be there, and they were. Every time. If you are in the market for HVAC work and want a company that respects your home, your time, and your investment, I would not hesitate to recommend Landry Mechanical.
