Common projects
- Gas range or dryer: usually a short extension from an existing line, at the low end of the extension range.
- Tankless water heater: often needs a larger line than the old tank; see tankless installation cost.
- Outdoor grill, fire pit or pool heater: runs outside often require trenching or boring.
- New service from the street: the most expensive option, involving the gas utility and the longest run.
Trenching vs. boring
HomeGuide prices trenching at $5 to $15+ per foot for digging, laying pipe and backfilling. Directional boring at $10 to $30 per foot tunnels under driveways, sidewalks and landscaping without tearing them up, which can be cheaper overall once restoration is counted.
Safety and permits
Gas work requires a licensed professional and, in most places, a permit and pressure test before the line is put into service. Call 811 before any digging so buried utilities are marked. If you smell gas, leave the home and call your gas utility from outside.
