Why Gas Leak Detection Matters

Safety First: Natural gas is highly flammable. A leak—even a slow one—can lead to dangerous buildup and explosive conditions. We help prevent accidents before they happen.
Protects Your Heating & Plumbing Systems: Gas-powered appliances rely on proper pressure and flow. Undetected leaks can shorten the lifespan of water heaters, boilers, and stoves.
Required for Code Compliance: Landlords, contractors, and homeowners must ensure their systems are sealed and functioning properly. We help you meet New York State safety codes with confidence.

How We Detect Gas Leaks

Combustible Gas Indicators (CGIs)

We use specialized combustible gas detectors that are approved by New York State to locate leaks with precision—no guesswork.

Air Pressure Testing

We perform air pressure tests on gas piping to verify the entire system is sealed. This is a key part of system inspections and new installations.

Soap Bubble Testing

For exposed joints and connections, we use soap solution to visually detect slow or pinpoint leaks.

Odor Detection & Response

If you smell that “rotten egg” odor in your home, it could mean a gas leak. We’ll investigate immediately and take action if needed.
