Certified Gas Testing & Leak Detection Services
Static pressure testing and gas leak surveys for residential and commercial systems.
A gas test is a critical safety measure to prevent dangerous leaks and is often required by utility companies or city inspectors in several common situations. We dispatch immediately with specialized detection equipment to verify your system's integrity.
Gas Testing — What Every Homeowner Should Know
When is a Gas Test Required?
When installing a new gas appliance (e.g., water heater, furnace, stove).
If you smell gas (a rotten egg or sulfur odor).
After your gas service has been shut off for an extended period.
As required for a building permit or during a home renovation.
During the buying or selling of a property.
After an event that could damage gas lines, like an earthquake or foundation work.
Gas Testing Process
Step 1: Initial Safety Assessment
Our technician arrives and discusses your concerns. We perform a visual inspection of your gas system and appliances to ensure the area is safe before proceeding.
Step 2: System Isolation & Pressurization
We safely turn off the gas supply at the meter and isolate the system. A specialized pressure gauge (manometer) is connected, and the lines are filled with air to a specific, safe pressure.
Step 3: Pressure Monitoring
The gauge is monitored for a set period as required by local code. If the pressure remains stable, the system passes. A drop in pressure indicates a leak.
Step 4: Leak Location (If Necessary)
If a leak is detected, we use electronic gas detectors and soap solution to pinpoint its exact location. We don't cause unnecessary damage to your property.
Step 5: Repair & Re-Test
We provide clear, upfront pricing for necessary repairs. Once approved and completed, we perform the pressure test again to certify the system is secure.
Step 6: Documentation & Service Restoration
Upon successful testing, we provide all necessary documentation for city permits, insurance, or real estate transactions. We safely restore your gas service.
