Gas Leak Repair questions, answered by experts

Capping a gas line costs approximately $125. The final price varies from $75 and $150 depending on your contractor’s hourly rate. To completely remove a gas line and cap it at the base can cost up to $250. Most contractors will charge a flat fee instead of by the hour since capping is often part of a larger project.

Not all gas fireplaces need a chimney. If you install a ventless gas fireplace, it will release low levels of combustion byproducts back into your living space (instead of pushing them outside through a chimney or vent). Ventless fireplaces burn fuel efficiently, so the emissions are minimal—but they could bother people with allergies or respiratory issues.

Replacing a gas valve on a water heater will take a professional plumber between 1 and 1½ hours. However, they may require extra time to diagnose the problem with your water heater, particularly since so many of the surrounding parts work together. Speak with your plumber before the job to confirm the pre-hour price and the approximate length of the job.

Although a gas company supplies gas to homes, connecting gas appliances, like a dryer, is not their responsibility. The primary role of a gas company is to safely deliver gas to a property and maintain the gas supply lines up to a specific point, typically the gas meter or shut off valve. The task of installation is usually taken on by the homeowner or professional dryer installer. 

In some cases, the answer is yes. Being licensed to work on gas lines requires additional specialized training beyond being a licensed plumber. If the plumber is also licensed as a natural gas plumber, they will be able work on natural gas lines. If the plumber is only licensed to work on water and sewer lines, then you’ll have to find another professional to do gas line work.
