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.

Wonderful experience with Landry from start to finish. Scheduling was easy, reminders were helpful (& not overwhelming). Rosalie was professional, knowledgeable, friendly & courteous. She explained everything post service, gave me some education/advice/options and did so without making me feel like she was trying to sell. One of the best tech experiences I’ve had in 30ish yrs. 10s across the board!

The technicians replaced my gas water heater and related plumbing. They initially provided several estimates, based on the equipment to be updated. Once I chose an estimate, they kept me updated about the installation progress. They were both professional and congenital and stayed to insure everything was working properly throughout the house. This was my first time using Landry but it won't be my last!

Prompt arrival and quick remediation. My outdoor hose was fused to spout. Provided options that helped me decide course of action based on cost and outcome. Provide advice for how to prevent future problems. Brass on brass/don’t forget to remove hose before winter. I would recommend Landry Mechanical and Plumbing to friends.

Ivan came to my house to do my fall maintenance service. You can't ask for a better person! He explained everything he was doing as he did it. Felt more at ease with him testing the part of the systems he was checking, knowing the values that the systems need to run at, and making sure they are working.

I will be asking for him from now on to service my system.

What did I pay? I pay $20 a month for a service contract and get 2 maintenance checkups, per year, free. Also an emergency call is a flat fee of $299 or $399 each call (Can't remember which one it was). If you have the contract, you pay $99 for the call, plus whatever work and parts they need.

Great company as long as they have people like Ivan. I only gave him 5 stars because i was prevented from giving him 10 stars.

Working with Landry was very easy. I most appreciate that they send a picture of the technicians, along with a background check clearance before anyone comes to the house. Friendly, professional, and thorough. Cost is given up front with no surprises.

I had a leaking connection on my water heater. The technician came and assessed and gave me options to repair or replace but said I could probably get a few more years out of the tank. He provided 3 quotes. Repair only. Replace with new tank. Replace with a tankless water heater. No push to go with. Full replacement which I appreciated. Friendly, professional, respect for my property. All things I look for.
