What San Jose Customers Say About Our Gas Services

Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

Gas Line FAQs for San Jose

How much does it cost for a gas line?
The cost of a gas line installation or repair can vary depending on the scope of the project. On average, gas line repairs cost between $200 to $800, while gas line installations can range from $1,200 to $4,500. Factors influencing the cost include the type of service, the complexity of the job, and any necessary permits. For a more accurate estimate, it’s best to schedule a consultation with CPI Services.
Is a gas line leak covered by insurance?
In most cases, gas line leaks are covered by homeowner's insurance, but this depends on the specifics of your policy. Insurance coverage for gas line repairs can vary, so it's advisable to check with your insurance provider to understand your policy details. Be sure to document any damage and repairs, as this will help when filing a claim.
How long does it take to fix a broken gas line?
The time required to fix a broken gas line can depend on the severity of the damage and the complexity of the repair. Typically, a gas line repair takes between 2 to 6 hours, but it may take longer for more extensive damage or if multiple repairs are required. A professional inspection will give you a more accurate estimate of the time needed to complete the repair.
Can I use plumber's tape to seal a gas line?
No, you should never use plumber's tape to seal a gas line. Plumber’s tape is not designed to handle the pressures or chemical properties of natural gas. It’s essential to use materials and methods that are specifically intended for gas lines, such as gas-rated thread sealant or gas tape that meets the necessary standards. Always rely on a licensed professional for gas line repairs.
How far does a gas line have to be from a property line?
The distance a gas line must be from a property line varies by local codes and regulations. In San Jose, gas lines typically must be installed at least 3 to 5 feet from property boundaries. This is to ensure safety and proper installation. Always consult with a licensed plumber to ensure compliance with local regulations.
