How Much Does Gas Fireplace Installation Cost in 2026?
By GasFireplaceFixer.com · Gas Fireplace Repair Guide
Gas fireplace installation costs range from $2,000 to $8,000 for most residential projects depending on the type of unit, venting requirements, gas line work, and finishing. Understanding what drives cost helps you budget accurately and avoid surprises.
Total Cost Ranges by Type
Direct-vent gas fireplace (new installation): $3,000-7,000 total including unit, venting, gas line, and finishing. Gas fireplace insert (replacing existing wood-burning fireplace): $2,000-4,500 total. Gas log set (in existing masonry fireplace): $500-1,500 installed. Freestanding gas stove: $1,500-4,000 installed. These ranges reflect typical US contractor pricing in 2026.
Unit Cost
The appliance itself typically represents 40-60% of total project cost. Entry-level direct-vent units start around $800-1,200. Mid-range units with better heat output and features run $1,500-2,500. Premium units from Napoleon, Heat & Glo, or Mendota run $3,000-6,000 for the appliance alone. Higher-priced units generally offer better efficiency ratings, more realistic flame appearance, and longer warranties.
Gas Line Installation Cost
If you don't have an existing gas line near the installation location, adding one costs $15-25 per linear foot plus a shutoff valve and connection fittings. A typical run of 20-30 feet adds $400-800 to the project. In areas without natural gas service, propane is an alternative — propane tank installation adds $500-2,000 depending on tank size and placement.
Venting Cost
Direct-vent systems require coaxial pipe that draws combustion air from outside and exhausts to outside. Venting materials run $300-800 for a typical installation. Labor for venting through an exterior wall is straightforward ($200-400). Venting through a roof or long horizontal runs costs more ($500-1,200 for materials and labor).
Labor Cost
Certified fireplace installation labor typically runs $500-1,500 depending on complexity. Simple exterior wall direct-vent installations are on the lower end. Complex installations requiring attic access, long gas line runs, or custom framing are on the higher end. Always hire a licensed contractor for gas work — DIY gas line installation is illegal in most jurisdictions.
Permits and Inspections
Most jurisdictions require a permit for gas fireplace installation. Permit costs run $50-300 depending on your municipality. The permit process ensures the installation is inspected and meets local code requirements — it also protects your homeowner's insurance coverage. Always verify permit requirements with your local building department before starting.
