Question: how much does it cost to convert my fireplace to gas?
Answer: Installing a gas line and either vented or vent-free gas logs will cost $500 to $2,500. (Note the cost of installing vent-free gas logs is often about $200 more than the cost for vented.) Gas inserts cost $2,000 to $5,500. Expect to pay more if installers are challenged to get the gas line to your fireplace.
