Instant heat for Marietta's mild but real winters.

Most gas fireplace and insert installations in Marietta run $3,500 to $9,500, depending on the unit, whether you're converting an existing masonry firebox, and how much gas line work is involved. An insert going into an existing wood-burning fireplace—common in the brick ranches and colonials scattered across zip codes like 30062 and 30064—sits on the lower end if a gas line is already nearby. New direct-vent units built into a remodel, with fresh gas line runs and framing, land toward the higher end. A local dealer will confirm the number after seeing your fireplace in person.

Yes, and it's one of the most common projects for older Marietta homes. Many houses built through the 1980s and 90s have a masonry firebox that was designed for oak, pine, or hickory but rarely sees a real wood fire—Marietta's mild winters just don't create much demand for cutting and stacking firewood. A gas insert uses your existing chimney with a stainless liner, typically running $3,800 to $8,000 depending on the model and gas line access, and gives you real flame and heat without the ash, smoke, or wood storage.

Most of Marietta and inner Cobb County sits within the Atlanta Gas Light distribution footprint, and Georgia's deregulated market means you select your own gas marketer for billing—Atlanta Gas Light just owns the pipes. If your address falls outside that service area, or you're farther out toward unincorporated Cobb, propane is the standard fallback, supplied by a regional propane company with either a leased or owned tank. Most gas fireplace models can be configured for either fuel; your installer sets the correct orifice and regulator.

Most modern gas fireplaces will, which matters in Marietta given how ice storms occasionally knock out Georgia Power or City of Marietta service for days at a time—the 2014 Atlanta-area ice event is still a fresh memory for a lot of Cobb County homeowners. Units with intermittent pilot ignition (IPI) run on a battery backup that kicks in automatically when the power drops, so the fireplace still lights on demand. Valor fireplaces go a step further: their pilot generates its own electricity through the thermocouple, so there are no batteries to remember at all. Ask your local dealer about the ignition system on any unit you're considering.

A gas fireplace is a fully built-in unit framed into a wall—typical for new construction or a major remodel. A gas insert drops into an existing masonry fireplace opening and uses the chimney as its vent path, which is the common route for Marietta's older brick homes. A gas stove is a freestanding cabinet unit, less common here than in colder markets but occasionally chosen for a sunroom or finished basement. For most Marietta homeowners with an existing wood-burning fireplace they no longer use, an insert is the straightforward answer.

Generally yes—a building permit and a gas line permit, pulled through either the City of Marietta or Cobb County's building department depending on whether your address falls inside city limits (Marietta's zip codes span both). The gas line connection itself needs a licensed gas-fitter. Most established hearth dealers handle this paperwork as part of the installation, coordinating the gas work, venting, and inspection so you're not managing separate trades yourself.

Vented (direct-vent) units draw combustion air from outside and exhaust it back outside through sealed venting—they're the option most Marietta dealers install and recommend by default. Vent-free units are legal in Georgia and burn without external venting, but they release some water vapor and combustion byproducts into the room. Given how much Marietta already deals with summer humidity, most local installers steer homeowners toward vented units to avoid adding indoor moisture, reserving vent-free for rooms where running venting simply isn't possible.

Plan on an annual inspection—a technician checks the burner, pilot or ignition system, venting, and gas connections, and cleans the glass and interior. It's a lighter job than wood chimney sweeping but just as important for safety, and most Marietta-area service providers charge $150 to $250 for the visit. Fall, ahead of the first cold snap, is the most common time homeowners schedule it.

Wood is genuinely uncommon here—with an average winter low around 32°F and only a light winter heating load, most Marietta homeowners don't need firewood as a real heat source, and there's little local infrastructure (cutting permits, firewood suppliers) built around wood heat the way there is in colder states. Electric fireplaces are the budget option, typically $400 to $1,500 installed, great for ambiance and light supplemental warmth but limited on real output. Gas splits the difference: real, immediate heat for those 30-degree nights and the occasional ice storm, without the upkeep of wood. For most homes in this climate, gas is the practical choice, with electric reserved for secondary rooms.

Yes—with an asterisk. Fireplaces are hot and TVs don't like heat. Either put a mantel between them to deflect rising warmth, or choose a fireplace with heat-management technology that creates a cool zone on the wall above—the wall stays around 125 degrees, barely warm, while the room still gets full heat. If you like clean lines and don't want a mantel, heat management is the answer.

Open fireplaces suck—literally. As the fire burns, it consumes air your furnace already paid to heat and pulls it out through the chimney, so the house is actually colder after the fire goes out than before you lit it. An insert fixes this: it seals the chimney, puts fixed glass across the front, and turns that hole in your house into a real heat source.

For an average home—covering the fireplace, the vent pipe, and basic installation—a budget between $3,900 and $5,500 gives you a lot of options across wood, gas, and pellet. By the time you add finish work, gas line, and electrical, the average complete installation lands between $5,000 and $12,000 all-in. In a remodel or new build, a good rule is to put about 2.5% of the total project cost toward the fireplace.

On average, a fireplace adds back to the home about the same amount you spent installing it. Add the monthly savings from heating the rooms you actually use instead of the whole house—often hundreds of dollars a year—and the value case is strong before you even count what a fire does for how your family uses the room.
