Should a plumber be licensed and certified to install gas lines?

<div><p>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 <a href="https://www.angi.com/angi-license-check.htm">state licensing tool</a> to review the local plumber guidelines.</p><p>As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:</p><ul><li><p>The owner, principal, or relevant manager passed a criminal background check</p></li><li><p>Required to have applicable state and local licenses</p></li><li><p>Maintain an average star rating of 3.0 or better on our network, if they have at least one review</p></li><li><p>Paying to advertise their services</p></li><li><p>Meeting any other eligibility criteria required by Angi</p></li></ul><p>Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.</p></div>

How much does it cost to fix a gas leak?

<div><p><a href="https://www.angi.com/articles/average-gas-line-repair-and-installation-costs.htm">Fixing a gas leak costs</a> about <b>$45 to $150 per hour</b> for a plumber or gas line specialist. The job’s overall cost will vary depending on the location of the leak. A leaky junction or connection behind the stove or dryer will likely cost about <b>$120 to $170</b>. But for a leak that requires a gas fitter or plumber to excavate a pipe in the yard, the cost could rise to <b>$1,500 to $5,000</b>. Keep in mind that gas leaks are very serious issues, so don’t hesitate to contact a plumber or gas line specialist immediately.</p></div>

How long does it take to fix a gas leak?

<div><p>Fixing a gas leak can take anywhere from <b>one to 24 hours</b>, depending on the location and magnitude of the problem. A gas line specialist or gas plumber should be able to give you an estimated time to completion once they evaluate the situation. If your city’s utility company works to fix a gas leak, it will likely have information available about the anticipated time for gas service to be restored. </p></div>

What are common gas line repair costs?

<div><p>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:</p><ul><li><p>Cap a gas line: $75–$150</p></li><li><p>Gas system inspection: $150</p></li><li><p>Pressure test: $75–$500</p></li><li><p>Damaged or corroded pipe: $6–$7 per linear foot</p></li><li><p>Repair gas leak: $120–$5,000</p></li></ul><p></p></div>

Who should fix a gas leak?

<div><p>A <a href="https://www.angi.com/nearme/natural-gas-plumbers/">local natural gas plumber,</a> gas fitter, or gas line specialist should fix gas leaks. Installing gas lines and connections improperly can lead to dangerous gas leaks and explosions. Only a certified plumber or gas line specialist should run gas lines. This is not a job to try out DIY skills, so hire a professional gas plumber or gas line specialist immediately to find the cause of the leak and fix it quickly. </p></div>

"Tri State was prompt—they had a tech out within hours when our 20-year-old HVAC broke down. The repair estimate was $800–$1,200, and they also sent a salesman, Mike, to discuss replacement. Mike was courteous and knowledgeable, but, when we sat down to review the quote, the sales process turned into a bad car-buying experience. They started at $34,000, then "discounted" to $29,300—$10,000 -$12,000 higher than other quotes for the exact same unit. Even factoring in their warranty, they remained $8,000–$10,000 overpriced. Mike also claimed they were a four-generation family-owned business, but I later found out they’re owned by Sila Services, a Goldman Sachs private equity firm—which feels misleading. To their credit, canceling was easy (though I hadn’t signed a financing agreement or put money down). Bottom line: Get multiple quotes. Their pricing was excessive, and the sales tactics felt manipulative."

"UPDATE: My previous review still stands from a couple years ago for that specific plumber only - but my most recent experience has been a nightmare. Will never recommend this company ever again. They definitely have changed since my last experience. Not only did the plumber they sent (12/9/24) not do anything to make any effort to clear a clog ( I won’t be petty and provide a name, even though I should) - after signing agreements and I asked if I should pay now -he said I probably should so he could get started - I know I should’ve just sent him on his way, but wanted to get this fixed (astronomical for what was -or in this case wasn’t done- and was told that prices had gone up a lot since my previous experience). He also had to inform me that normally they send the new guys to do this type of work ( implying unclogging drains was beneath his “expertise “). Then proceeded to tell me he was convinced it was a collapsed drain (after snaking the drain for less than a few mins)and that I probably had water flooding under the foundation said he needed to get a hold of their camera guy to be sure - he went to his truck to call him came back in, about 20-25 mins later to tell me he couldn’t get a hold of their camera guy and left a message for him. He then said he would try one more time with the snake - did the same amount of effort as the first time and said we would have to wait until he could get a camera down there and that we would have to let the drain dry out a bit so it would probably be the following week. Packed up his stuff and said I should call him in an hour to see if he heard from the camera guy (why should I do the calling for follow up??) When he left, he seemed to struggle backing out and damaged our lawn (have security camera footage). I called the company the next day and was sent to voicemail (left a message that said I had some concerns but didn’t leave a lot of detail) and was told that I should hear from someone that day - I did not. Called the next day and was told by the supervisor of the phone people that the phone person should have told me it was 24-48 hours before a manager would respond and she would not allow me to speak to anyone else. I did not hear back from anyone in 72 hrs, so I called back and then was told that the manager was out (conveniently). I gave up calling them and called another plumbing company who fixed the issue in a short amount of time (no collapsed drain, just a good ol’ clog). Decided to call Len the Plumber one more time ( 12/23/24) 2 weeks AFTER my original call and was told that there was a note in my file that said the mgr did call 3 days prior to this call (there had been no conversation or missed calls or voicemail received by me - so either he called a wrong number or this was a lie) and in the notes the mgr (Brian, I was told by the phone person)stated that I was told about the pricing and that was it. Not sure where he got his information of what he thought my issue was, since I didn’t leave a lot of info when I spoke to the phone people other than it was frustrating to be told I would get a call in 24-48 hrs. This last phone person said she would send an email to all managers with my concerns and would hope someone would assist. No response. (12/28/24). Think twice before using this company. It has changed ownership twice since the original owner- history has shown as ownership changes in companies , so do priorities and not to the benefit of the customers."

"Everything went very smoothly. Sam, the plumber, and is highly professional and knowledgeable. He replaced 3 faucets, 2 sink plugs, two valves, and two supply lines. Sam inspected the p traps, and he added adhesive where it was necessary. Sam also took a look at my two year old hot water heater, and he assessed my water supply to this unit. We discussed performing a complete drain, and check of the components of the heater at a later date. Sam also advised me that a toilet in the basement should be replaced with a more updated commode. We rarely use this toilet, but it's 35 years old. I felt comfortable speaking with Sam. I did not sense he was doing a sales pitch."
