"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

While working with Alliance Service Pros, you're guaranteed to get that fast, attentive service, but you'll also receive a variety of additional benefits: Above & beyond service: We go that extra mile to ensure total, 100% satisfaction in everything we do. Community driven: As a locally owned & operated company, we always give back directly to the communities we serve. 5-star reputation: Our reviews are solely from customers in the local, immediate area, like you.

This company is nowhere near professional and all they do is steal money . stay far away !!!!!! If anyone wants to join my lawsuit contact 848-248-6834"

"this company is the scum of the earth. their google reviews have to be made by friends and family because they robbed me. They didn’t do their job properly and charged insane prices. I called to have a line clog cleared out and paid extra for the camera, they still have not provided the camera 3 weeks after I paid for it. When I called to complain about the clog not being fixed and the camera still not being provided, they told me I’d have to pay again even though the guy didn’t do the proper job the first time and they lied and said that the camera wasn’t part of the price but “complimentary“, even though the plumber told me it was an extra charge. this company is awful, half a mortgage payment for 15 minutes of labor, and they didn’t even get the job done, these are disgusting people."

Gas Leak Repair questions, answered by experts

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

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

In most cases, yes, it’s safe to light a gas water heater manually, but you should shut the gas off first, open a window, and let the space air out for about 10 minutes. Modern water heaters shut the gas off entirely if the pilot light goes out, but airing out the area beforehand is good practice and will ensure it’s safe to relight your pilot light manually. Just make sure you turn the gas valve to “pilot” before lighting. If the light keeps going out or won’t light at all, call in a professional.

Some cities or states may require you to have an earthquake gas shut-off valve. Your insurance provider may also have requirements for installing this valve. Even if you don’t have to have one by law, it’s wise to have a natural gas plumber install one anyway. These devices can be lifesaving and prevent fires or explosions in the event of a gas leak.

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