Why Choose James A Douglas Plumbing and Gas Fitting Image

Gas Appliance Hookup and Installation

Getting a new gas range, dryer, fireplace, or outdoor grill connected means tying into your home's gas supply safely — proper fittings, pressure testing, leak checks, and making sure the appliance is vented correctly. James A. Douglas Plumbing handles gas appliance hookup and installation for all major residential appliances, including running new supply lines when the existing setup doesn't reach.

Gas Line Installation

Whether you're extending gas service to a new part of the house, adding a line for a generator, or running gas to an outdoor kitchen — new gas line installation requires proper sizing, code-compliant materials, pressure testing, and inspection. We install residential gas lines from the meter to the appliance and handle all necessary testing before the system goes live.

Gas Line Leak Detection and Repair

If you smell rotten eggs near a gas appliance or along a gas line, that's the mercaptan additive telling you there's a leak. Don't ignore it. James A. Douglas Plumbing provides gas leak detection and repair using professional-grade equipment to locate the source, isolate the problem, and make the repair. If you suspect a gas leak, leave the area and call immediately.
