"Dreadful experience. We had been customers of Astacio since 2015 when they installed our first tankless boiler which failed completely after 7 years and needed to be replaced in late 2022. ($10,000+) Their second one just stopped working; a dodgy board? The part is under warranty but they want almost $1,000 to replace it in the boiler; probably less than 2 hours work. I thought they used to be a good local business with ties to the community but be careful; their tankless boilers are unreliable and they'll try to rip you off when your heat goes out in the winter. So much for standing by their work. I'll never use them again."

"The upgrade of a new water heater and the removal of the old water heater seem like it was a good job. However, the plumber did too much haggling for more money. I checked the price of this job ahead of time as I always do with any work that needs to be done at my home. Parts and labor, I always need to know up front. I do not like it when any workers come off as greedy and try to insult my intelligence. I hope the work of this young man lasts. However, I would have been able to give him 5 stars, if he had chosen to fully conduct himself as a professional in the end. This plumber was paid $1700. The price I paid was completely within the range of what it cost for parts and labor to upgrade an old water heater, with a new water heater. I wish his well..."

Gas Leak Repair questions, answered by experts

Safety steps include proper vent installation, connector tightness, and leak testing. A safe environment must be maintained throughout.

Almost all new buildings in California need an earthquake shut-off valve. The requirements for an earthquake gas shut-off valve (and who can install it) depend on where you live. For example, according to the Los Angeles Municipal Code, you’re required to hire a licensed contractor to install one whenever you build, sell, or renovate a home. Check with your local building department for your city’s laws on installing, permitting, and inspecting earthquake shut-off valves.

No, you shouldn’t leave a gas line uncapped because it can allow gas to escape into your environment, which can lead to fires, explosions, and health hazards. That’s why it’s critical to properly cap and seal any unused gas lines as soon as you can. If you’re not comfortable with that, you can always call a licensed plumber to safely handle it for you. 

No, homeowners should never attempt to fix a gas leak themselves. Gas leaks pose serious health and fire hazards. Exposure to leaking gas can make you sick, and accumulated gas can ignite and explode. So always take leaks seriously and seek the help of a pro right away. While you may be able to detect a gas leak, always call a licensed professional to handle repairs and replacements.

The cost to install a gas line is $540 on average, but most spend between $260 and $820. In extreme cases, your total cost could reach $1,350.

Factors that influence the cost of a new gas line installation include your geographic location, materials, and labor. Gas line installation costs are higher in urban versus rural areas due to the drilling technique required to get under road structures.
