"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

Most qualified local plumbers in your area should be able to help with this job. However, it's always best to check with your utility company before starting any gas-related project. Speak with them about your needs and request recommendations for licensed plumbers who can pull permits and properly install the line.

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

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.

Gas lines are built for longevity, so they can last up to 50 years when installed properly. However, normal wear and tear are possible, especially in moderate climates. Having a plumber or local gas company inspect your gas lines every year is best to ensure there are no hidden leaks or other dangerous problems.

Costs depend on furnace size, ductwork modifications, labor, and efficiency ratings of the chosen system.
