"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."

Gas Leak Repair questions, answered by experts

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

  • Cap a gas line: $75–$150

  • Gas system inspection: $150

  • Pressure test: $75–$500

  • Damaged or corroded pipe: $6–$7 per linear foot

  • Repair gas leak: $120–$5,000

Because of the potential danger associated with incorrectly capping the gas line that serves the gas fireplace, many people will choose to hire a professional to do the work. Some homeowners may choose to hire a pro to only handle the gas line for them. They then may attempt to remove the actual insert on their own, which is a challenging—but not impossible—DIY project.

Temporarily capping a gas line—for renovations or during travel—doesn’t require a permit. If you plan to remove a gas line and cap it completely, you’ll need to apply and pay for one through your town or city. Depending on your region and its local codes, you may pay between $25 and $100. To avoid a gas leak or other hazards, some cities take the job of permanently adjusting or capping a gas line out of the hands of homeowners. Instead, they require hiring a professional gas plumber.  

No, fixing or patching a hole in a gas line may not seal it completely. A patch should be a temporary solution because the damaged area will be weaker than the rest of the pipe, increasing the likelihood of future leaks. Therefore, if a gas line incurs damage, call a licensed plumber and have it replaced right away.

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.
