"Very professional! They have done two different jobs. The first was a problem with my sewer line backing up. They found that it was full of tree roots. The plumber worked for hours cutting through the roots. It was a long, hard job and he was determined to get it cleaned out. The second job was to clean the kitchen drain. Obviously, the previous owner dumped lots of grease down the drain. It was a lot to clean out. The cost wasn't bad considering that the tree roots ended up being a day and a half project."

Gas Leak Repair questions, answered by experts

The best sealant for gas pipes is usually a pipe joint compound, or pipe dope. It creates a durable, leak-proof seal that is resistant to high pressure and vibrations, and it doesn’t break down like tape can. Yellow Teflon tape, or PTFE tape, can also be a good option and is a safe and reliable sealant for gas pipes when you or a pro apply it correctly.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

The biggest disadvantage of propane is that heating systems and appliances powered by propane tend to cost more than gas-powered ones. Propane is also dangerous since it can create frostbite if it touches the skin and can easily combust if mishandled. It’s also quite cumbersome to buy or replace propane tanks, so many people choose to have propane delivered to their homes—an extra cost and logistical challenge that can be a headache.

Before you hire a natural gas plumber, it’s a good idea to get quotes from multiple pros to find the best value. When speaking with prospective plumbers, ask them if they’re licensed to work with gas lines, what precautions they take to ensure safety during the project, and how to handle an emergency if there’s a leak after the job. You may also want to know about warranties or guarantees, additional costs, how to prep your home, and if you’ll need to relight your pilot lights.

Yes, it’s possible to cap a gas line yourself if you’re no longer using it or are simply going out of town for an extended period of time. It’s essential to follow the steps on properly capping a gas line yourself. If you’re uncomfortable with any of the steps, you may want to bring in a natural gas plumber for added reassurance.
