1 As a very general estimate, installing gas line costs $20 to $30 per foot. 2  In some areas and circumstances, however, the price could be $75 per foot or more. 3  This price should include the costs of trench digging and all necessary permits, drawings, and inspections.
For gas stoves, installation costs are $100 to $125 if there are already supply lines installed for the gas. If new lines must be installed, the costs can go up to $200 or more. If you need a stove hood or vent installed, the cost is $166 to $284, depending on the complexity of the job. Return to Top.
