Gas Line Repair & Leak Detection
Gas leaks are a serious safety hazard. Whether you notice a sulfur-like odor, hear a hissing sound near a gas appliance, or see dead vegetation above a buried line, don't ignore it. Our licensed technicians use electronic combustible gas detectors to locate leaks precisely — without unnecessary excavation or pipe exposure.
After locating a leak, we perform pressure testing on the repaired section to confirm the line is sealed before putting it back into service. Common causes of gas line leaks on Long Island include:
- ✓Corroded or aging iron pipe connections (common in homes built before 1970)
- ✓Damage from settlement or shifting soil
- ✓Improper fittings from DIY or unlicensed work
- ✓Appliance connections that weren't pressure-tested at installation
- ✓Vibration loosening threaded fittings over time
New Gas Line Installation
Whether you're adding a new gas appliance, extending service to a new part of your home, or establishing gas service for the first time, a licensed contractor must pull the permit and perform the work. All gas line installations in Nassau and Suffolk County require county permits and a final inspection before gas service can be turned on.
We handle the full process: permit application, installation, pressure testing, and coordination with the utility for final inspection. Residential gas line installation typically costs $500–$2,000+, with price varying by line length, pipe material, and county permitting timelines.
Gas Appliance Hookups
Adding a gas appliance — or replacing an electric one with gas — requires a proper licensed hookup and pressure test. We install dedicated gas supply lines and connection fittings for:
- ✓Gas dryers — dedicated gas line and proper flexible connector
- ✓Gas stoves and ranges — supply line, shutoff valve, and flexible connector
- ✓Standby generators — correctly sized line for BTU demand
- ✓Outdoor BBQ gas lines — buried line run to outdoor connection point
Appliance hookups typically cost $150–$400 each, depending on the appliance and whether a new dedicated supply line is needed. Every hookup includes a pressure test and leak check before the appliance is put into service.
Gas Line Permitting on Long Island
All gas line work in Nassau and Suffolk County requires permits — no exceptions. Work performed without a permit is illegal, may void your homeowner's insurance, and creates safety risks that won't be caught without an official inspection. When you hire us, we manage the entire permit process: application, scheduling the inspection, and coordinating utility involvement when required.
Permit approval typically takes 1–5 business days in most Long Island municipalities. We schedule the installation work to begin as soon as the permit is in hand so there's no unnecessary delay.
Our Process
Safety Assessment
We begin every gas job with a safety check of the existing lines and the area where work will be performed.

We apply for the required Nassau or Suffolk County permit before any work begins. Permit approval typically takes 1–5 business days.
Work Performed
Licensed technicians complete the installation or repair using permitted materials. All work follows Long Island building code requirements.
Pressure Test & Inspection
We pressure-test the repaired or installed line before backfilling or closing walls. Final county inspection confirms compliance.
