"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

Installing a gas line can be extremely time-consuming and dangerous, so you will want to hire a seasoned professional. Perform a thorough search ahead of time to find a reputable and reliable plumber. Pay special attention to licensing and insurance as you go about choosing the best contractor for your needs.

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.

Many people find switching from an electric stove to a gas stove well worth the hassle. After all, gas stoves last up to 15 years, whereas most electric stoves only last up to 13 years. Plus, the sentiment and joy of cooking over a real fire is indeed irreplaceable—and offers more precise temperature controls than electric cooktops. The cost of converting an electric cooktop to a gas stove depends on whether your kitchen already has gas supplies, and the cost can range from $125 to $2,000. Also, make sure your new stove’s dimensions match the old one.

You can maneuver your gas grill into place, but you cannot connect the grill to your gas source yourself. All municipalities mandate that a certified plumber carry out this work, so you’ll have to reach out to a plumber or a gas grill installation company in your area. Given how dangerous a gas leak can be, gas lines and connections are highly regulated, so you’ll need a professional’s help and a permit to install a gas grill.

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.
