Which is the bigger installation job — gas logs, a gas insert, or a full fireplace replacement?
In order: gas logs are the smallest job, an insert is the middle, and a full fireplace replacement is the biggest. A vented log set is often done in a day — gas line, set, test. An insert adds a chimney liner and surround. A replacement adds demolition, framing, new venting, and finish work, which is why it costs and disrupts the most.
Gas logs: the one-day job
A vented log set going into an existing masonry wood-burning fireplace is the lightest lift of the three. The real work is the gas line — run or extended by a licensed contractor, permitted with your county, and pressure-tested — plus setting and leveling the logs, securing the damper for vented operation, and testing everything. Most are done in a single day. It's the smallest job because nothing about the fireplace itself changes; you're adding a burner to a firebox that already exists and already vents.
A gas insert: a day of real work
An insert is a sealed heating appliance slid into the old firebox, so the scope grows: a new liner runs the full height of the chimney, a surround panel closes off the old opening, the gas line comes to the unit, and most inserts want an electrical connection for the blower. It's still typically one working day, but with several trades' worth of tasks packed into it — and the payoff is heat, since inserts commonly run 70 percent efficient or better while an open masonry fireplace can actually run a net heat loss.
Full replacement: construction, not installation
Tearing out a fireplace and building in a new one is a construction project — demolition, framing, new venting through the wall or roof, gas and electrical, then the finish work of surround and mantel. For budget context: gas fireplace installation typically runs $3,500–$8,000 installed, while a fully vented gas or wood fireplace with a new fuel line and chimney runs $4,000–$12,000, and wood and chimney jobs usually take two to three days where most gas work wraps in one.
