"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

I had planned to work a half day from home but ended up working the whole day from home. (I am fortunate that my employer is flexible.) Other than that, everything was great. They were professional, friendly, did good work, put down a tarp to protect my laminate flooring, and cleaned up after themselves. I would recommend them to others and would use them again."

Gas Leak Repair questions, answered by experts

Only yellow Teflon tape is approved for use on gas lines. Also called yellow PTFE tape, it is thicker and specifically rated for use on natural gas and propane connections. Standard white Teflon tape is not safe for gas applications. If you have questions about sealing gas line connections, contact a pro like a gas line contractor or plumber who installs or runs gas lines.

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

Leaks, low pressure, or inefficient flow are common problems needing professional repairs.

Installing a gas line is no simple task. From start to finish, you’re looking at anywhere from six to 12 weeks to acquire the correct permits, dig a trench, and connect your appliances. Naturally, the longer the gas line, the longer it will take to complete. If your plumber needs to hire additional contractors to dig trenches and navigate around or remove obstacles, this could put you at the longer end of the timeframe. 

Once the land is prepped and licenses acquired, installing the actual line may only take a few days to a few weeks, weather permitting.

Some cities or states may require you to have an earthquake gas shut-off valve. Your insurance provider may also have requirements for installing this valve. Even if you don’t have to have one by law, it’s wise to have a natural gas plumber install one anyway. These devices can be lifesaving and prevent fires or explosions in the event of a gas leak.
