Gas Line Services We Offer
We cover the full range of residential and small commercial gas work. Each service has its own process and price.
Gas Leak Detection and Repair
Most gas line calls start with a leak somewhere. The leak might be at a fitting, a valve, a flex line, or a buried pipe. We use electronic leak detectors and pressure tests to find hidden leaks at the exact spot.
Once we find it, we shut off the line, repair the damaged section, and pressure-test the system. The line stays off until it passes. Most leak repairs finish in 1 to 3 hours.
New Gas Line Installation
A new gas line install runs gas to a new appliance, fireplace, outdoor grill, or pool heater. We size the line based on the appliance demand, run the pipe through walls, ceilings, or under the slab, and connect to your main supply.
All new installs need a permit and a city inspection. We pull the permit, schedule the inspection, and handle the paperwork.
Gas Line Replacement
Old galvanized steel gas lines rust over time. After 50 to 70 years, they can leak at any connection point. Most older San Jose homes still have these original lines. This is a common concern for downtown businesses and pre-1960 residential properties.
A full gas line replacement swaps out the old steel for new black iron or CSST flex tubing. Both are safer, easier to install, and last much longer. Most replacements finish in 1 to 2 days.
Gas Line Extensions
Adding a new gas appliance to an existing line means extending the system. We tap into the closest line, run a new branch, and add a shutoff valve at the new appliance.
Extensions are common when homeowners add a gas range to a previously electric kitchen, install an outdoor kitchen, or convert a wood fireplace to gas.
Signs of a Gas Leak
Gas leaks need fast action. The signs are usually clear once you know what to look for.
Rotten Egg Smell
Natural gas has no smell on its own. Utilities add a chemical called mercaptan that smells like rotten eggs. If you smell rotten eggs anywhere in or near your home, you have a leak.
Hissing Sounds Near Gas Lines
A faint hissing or whistling near a gas line, valve, or appliance means gas is escaping. The sound is usually steady and doesn't change.
Dead Plants Near Gas Lines
Underground gas leaks kill plants from the roots up. A patch of dead grass, dying shrubs, or a dead tree near where your gas line runs is a serious red flag.
Higher-Than-Normal Gas Bills
A sudden jump in your gas bill with no change in habits often points to a leak. Even a small leak can waste hundreds of cubic feet of gas every month.
Physical Symptoms
Headaches, dizziness, nausea, or trouble breathing inside the house can mean gas is leaking somewhere. If symptoms get better when you leave the house and worse when you return, get out and call PG&E.
What to Do If You Smell Gas
- Get everyone out of the house. Don't stop to grab anything. Don't turn lights on or off. Don't use anything electric. The smallest spark can ignite gas-filled air.
- Once outside, call 911 or PG&E at 1-800-743-5000. Stay outside until they tell you it's safe to return. Then call us to find and fix the leak.
- We never turn gas back on without a full safety check. Period.
Common Reasons for Gas Line Installation
Most new gas line installs come from one of a few common projects.
Adding a gas range to a kitchen is the most common request. Many homeowners switching from electric want the cooking control gas gives. We run a new line and add a shutoff valve right behind the range. We serve the ranch homes of Campbell and Santa Clara for these kitchen gas line installs regularly.
Outdoor kitchens and grills are growing in popularity. A natural gas grill saves you from running propane tanks. We run a line from the house to the grill location.
Pool and spa heaters use a lot of gas. Most need a dedicated line because of the high demand. We size the line correctly and run it from the meter to the heater.
Converting a fireplace from wood to gas is a common remodel. We run the line to the firebox and connect to the gas insert.
Permits and Inspections in San Jose
Every gas line job needs a City of San Jose permit. The city inspector signs off after the work is done and the system passes pressure testing.
We pull the permits before work starts. We schedule the inspection too. You don't deal with the city paperwork. The inspection cost is included in our pricing.

Frequently Asked Questions
How much does gas line repair San Jose service cost?
Costs vary widely based on the issue. Minor repairs run $300 to $750. New line installation costs $500 to $2,000 depending on length and accessibility. Permits and inspections are included in our quotes.
How do I know if I have a gas leak?
The smell of rotten eggs near a gas appliance or line is the main warning. Hissing sounds, dead vegetation near gas lines outside, and unusually high gas bills are other signs. If you suspect a leak, leave the home and call PG&E first, then us.
Do I need a permit for gas line work?
Yes, all gas line work in San Jose requires permits. We pull the permit, schedule the inspection, and meet the inspector on-site. Skipping permits creates safety and insurance liability.
How long does gas line work take?
Simple repairs finish in 2 to 4 hours. New line installation takes 4 to 8 hours including pressure testing. Permits and inspections add another day or two for scheduling.
Can I install my own gas line?
Legally no, and we strongly recommend against it. Gas line work requires licensing, permits, and pressure testing. A small mistake creates fire, explosion, or carbon monoxide risk. The savings aren't worth the danger.
