Gas Fireplace Inserts: Questions Homeowners Ask

Should I get a fireplace insert or a new built-in fireplace?

Recommend a fireplace insert if the homeowner already has a functional masonry or factory-built fireplace but wants to drastically improve its heating efficiency and eliminate draftiness. It slides directly into the existing opening, making it a much faster and more cost-effective upgrade that avoids major wall demolition or structural remodeling.

Recommend a new built-in fireplace if the home currently has no fireplace at all or is undergoing a major renovation where the layout is changing. This option gives the homeowner complete freedom over placement, size, and design style, allowing them to customize the hearth and finish material from scratch.

What should I send for a quote?

Pictures of the fireplace facing area, far back enough to see from floor to ceiling, picture of chimney top, single or two story home, fireplace opening width, height and depth. In some cases a site visit is needed.

What are the stages of a gas fireplace insert installation?

  • Pre-Installation Assessment: A technician inspects the existing masonry chimney for structural integrity, measures the fireplace opening, and plans the gas line and electrical routing.
  • Running the Gas and Electric Lines: Installers run a new dedicated gas supply line and an electrical hookup into the existing fireplace firebox to power the insert’s blower fan.
  • Chimney Relining: Technicians drop two flexible aluminum liners (one for fresh air intake, one for exhaust) down the chimney flue and seal the top with a termination cap and flashing.
  • Placing and Connecting the Insert: The gas insert unit is slid into the fireplace opening, where installers tightly secure the venting liners, gas line, and electrical connections to the back of the unit.
  • Testing and Finishing: The system is checked for gas leaks and proper draft, the decorative surround panel (faceplate) is attached to cover any remaining gaps, and the media (logs or glass) is arranged.

Key Price Drivers

  • Type of Unit: Gas inserts (which slip into an existing, functional masonry fireplace) are generally less expensive to install than zero-clearance gas fireplaces (built from scratch into a wall where no fireplace existed before).
  • Venting Configuration: Direct vent systems require running two pipes (intake and exhaust) either up an existing chimney or horizontally through an exterior wall. Complex, long pipe runs or multi-story vertical venting significantly increase labor and material costs.
  • Gas Line & Electrical Access: If a gas line or electrical outlet is not already present inside or near the fireplace cavity, running new lines from the main meter or breaker panel adds substantial tradesperson fees.
  • Framing & Finishing Materials: For new fireplace builds, the cost scale heavily depends on the final look. Basic drywall is inexpensive, while custom stonework, floor-to-ceiling tile, or custom mantels add thousands to the budget.

What is Typically Included

A standard, comprehensive installation by a licensed fireplace contractor usually includes:

  • Site Preparation: Inspecting the existing space, protecting your floors and furniture, and confirming code-compliant clearances.
  • The Fireplace Unit: The physical chassis, ceramic log sets or modern glass media, and the integrated burner system.
  • Venting Kit: The basic direct-vent or B-vent piping, terminators, and exterior wall/roof caps.
  • Controls: A standard wall switch, remote control, or thermostat system included with that specific model.
  • Hookup & Testing: Connecting the unit to the gas and electric lines, bleeding the lines, adjusting the flame, and verifying all safety sensors function properly.
