McLean is one of the highest-demand markets in the DMV for new gas line work, driven by the large-home market: whole-home generators, multi-zone outdoor gas appliances (grills, fire pits, fire tables, pool heaters, patio fireplaces), and dedicated gas lines for guest houses, pool houses, and detached structures. Tim Whistler Plumbing handles all of this with Virginia licensing (2710020030 and 2710059613) and Fairfax County permitting.
The McLean residential market drives more gas line work per home than typical DMV residential. Common McLean projects: whole-home generator installations (requires running a dedicated gas line from the meter to the generator, often a substantial distance); outdoor entertainment setups (multiple appliances served by a single sub-panel of gas distribution); dedicated lines to detached pool houses, guest cottages, and outdoor kitchens; and upsizing existing service to handle high-BTU additions like tankless water heaters or commercial-grade ranges.
We evaluate the existing gas service for capacity, plan the new line routing (including any sub-distribution panels for multi-appliance outdoor setups), pull Fairfax County permits, install per code, pressure test the entire system, and coordinate the inspection.
Single appliance gas line installations typically run $500 to $2,500. Whole-home generator gas lines (which often involve longer runs) run $2,500 to $7,000. Multi-appliance outdoor gas distribution (grill plus fire pit plus pool heater) often runs $5,000 to $12,000. We provide written, itemized quotes before any work starts.
Yes. Dedicated gas lines to pool houses, guest cottages, and detached workshops are routine in McLean. The line is sized to the structure's appliance load, run from the main service, pressure tested, and terminated with appropriate shutoffs.
Yes. The gas line is one of three things a generator install needs (gas, electrical, and the generator itself). Our team is licensed across all three trades and handles the full install under one schedule and one set of Fairfax County permits.
