Gas Leak Detection & Repair in Fontana
Fontana spans a wide range of housing ages — from 1950s and 1960s central Fontana homes with aging gas infrastructure to newer North Fontana and Sierra Lakes developments built to modern code. The mix of residential and industrial corridors near Auto Club Speedway means we see everything from old-school iron pipe gas lines to recent CSST runs. Older homes often need gas line upgrades during remodeling work. Regal Plumbing & Rooter, a licensed family-owned plumbing company based at 2141 E Philadelphia St, Suite R in Ontario, CA (CA License #1097482), uses electronic combustible gas detection to pinpoint leaks in 30–90 minutes. Gas leaks are emergencies — same precision detection equipment we use for slab leaks. Serving all of Fontana 24/7.

Gas Line Services
Gas Line Services for Fontana Homeowners
Gas line upgrades during remodels are common in central Fontana. When homeowners replace water heaters, furnaces, or kitchen appliances in 1950s and 1960s homes, the existing gas lines often do not meet current code. We re-pipe and bring everything up to current standards in the same visit.
Seismic shut-off valves are essential in Fontana given the city's proximity to the San Andreas and San Jacinto Fault systems. CA SB 1445 requires them on new construction; for existing homes, retrofitting is a simple safety upgrade. The valve trips automatically at about a 5.4 magnitude shake.
New gas line installations for BBQs, fire pits, pool heaters, dryers, and stoves are a regular part of our Fontana work. Gas leaks are emergencies — we use the same equipment as our slab leak detection service.
KNOW THE SIGNS
Warning Signs of a Gas Leak in Your Fontana Home
The most obvious sign is the rotten egg or sulfur odor SoCalGas adds. A hissing or whistling sound near a gas line, meter, or appliance signals a pressurized leak. Dead or dying vegetation near buried lines can indicate an underground leak displacing oxygen in the soil — common in older central Fontana yards.
Pay attention to your body. Dizziness, nausea, or persistent headaches indoors can mean low-level exposure. An unexplained spike in your gas bill often reveals a slow leak. Visible corrosion on connections is a red flag in older Fontana homes. Professional gas leak detection in Fontana, CA is one phone call away.
EMERGENCY ACTION
What To Do If You Smell Gas in Fontana — Emergency Steps
The moment you detect gas in your Fontana home, your first instinct might be to flip a light or grab your phone — don't. Any electrical spark can ignite accumulated gas. Do not light matches and do not start a vehicle in an attached garage. Leave everything as it is.
Evacuate immediately. Get every person and pet out, leaving doors open to ventilate. Move at least 100 feet away. Call 911 from a cell phone or a neighbor's, then SoCalGas at 1-800-427-2200. Once they have secured the property, call Regal Plumbing at (909) 600-4561. Our 24/7 emergency team dispatches from our nearby Ontario shop.
OUR PROCESS
Our Gas Leak Detection Process in Fontana
Every Fontana gas call starts with an initial safety assessment. Our technician evaluates the area for hazards, checks ventilation, and confirms it is safe. If conditions are unsafe, we coordinate with SoCalGas before entering.
Next we use electronic combustible gas detectors to sweep every line, fitting, valve, and appliance connection — from old-school iron pipe in central Fontana to modern CSST in North Fontana. These instruments find concentrations far below what the human nose can sense. Once we identify elevated readings, we pinpoint the exact leak location with no demolition guesswork.
After repair, we run a full pressure test and monitor for any drop before service is restored. Most Fontana detection visits take 30 to 90 minutes.
