"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

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

If you're connecting your gas line to appliances, the pro doing the work may recommend flexible corrugated stainless-steel tubing (CCST). Polyvinyl chloride (PVC) with high-density polyethylene (HDPE) is another relatively inexpensive material commonly used for residential pipes. Ultimately, you'll need to find out what is permitted based on the code requirements in your area.

The cost to move a gas line is around $500 on average or $20 per linear foot . A pro will carefully disconnect the existing gas line and reroute it to its new path. This may involve excavation if the line is underground or drywall work to repair your walls and ceilings. The project will finish with a pressure test to check for leaks and turning the gas line back on.

Local codes often mandate specific fittings, permits, and vent considerations for permitted function and safety, which are enforced by professionals.

Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
