Find the right gas fireplace for your DeKalb County home.

A typical gas fireplace or insert installation in DeKalb County runs roughly $3,500 to $9,000, depending on the unit, the venting path, and whether you're on propane or in-town natural gas. A direct-vent insert dropped into an existing masonry fireplace with propane already on-site tends to land on the lower end. Homes that need a new propane tank set, a longer gas line run, or fresh venting through an exterior wall—common in older farmhouses around Liberty and Dowelltown—sit toward the higher end. A local dealer will give you a firm number after seeing the fireplace and chimney in person.

Yes, and it's a common project in older DeKalb County homes with existing masonry fireplaces built for oak or hickory cordwood. A gas insert typically slides into that same opening and uses a stainless liner run through the existing chimney, so you keep the look of the original hearth while gaining instant, consistent heat. Cost usually falls in the $3,500 to $7,500 range locally, with the swing driven mostly by whether propane service already reaches the fireplace or a new line and regulator setup is needed.

For most of DeKalb County, propane is the standard choice—natural gas mains, where they exist, are generally limited to in-town Smithville. If you're outside that footprint, which describes most of the county including Alexandria, Liberty, and the Center Hill Lake shoreline, your installer will set the fireplace up to run on propane, either from an existing tank or a new tank installed by a local propane supplier. Nearly every gas fireplace and insert sold today can be configured for either fuel, so availability doesn't limit your model choices—it just determines the fuel hookup.

Most modern gas fireplaces will, which matters in a rural county where ice storms can take out power lines for a day or more. Units with intermittent pilot ignition (IPI) run on a small battery backup that kicks in the moment power drops, so the fireplace lights on demand just like normal—you just need to keep fresh batteries in the unit. Valor fireplaces take a different approach: the pilot's thermocouple generates its own electricity, so there's no battery to remember at all. Either setup beats a fireplace with standing pilot only and no backup, which won't ignite once the power's out. Ask your local dealer which ignition system is on any model you're considering.

A gas fireplace is a fully built-in unit framed into a wall—the right call for new construction or a room without an existing chimney. A gas insert is built to slide into an existing masonry fireplace opening, using your current chimney as the vent path with a liner—the common upgrade for DeKalb County's older farmhouses and in-town Smithville homes with a wood-burning fireplace already in place. A gas stove is a freestanding unit that sits on the floor on its own hearth pad, similar to a wood stove but running on gas or propane—a good fit for a room with no chimney at all.

Yes—new gas fireplace and insert installations require a building permit through DeKalb County's permitting office, and any propane or natural gas line work needs to be handled by a licensed gas fitter. Most local hearth dealers coordinate the permit and the gas line work as part of the installation, so you're not left managing separate trades yourself. This is one of the reasons it pays to work with an established local dealer rather than a big-box install crew unfamiliar with the county's process.

Vented (direct-vent) gas fireplaces draw combustion air from outside and exhaust the byproducts back outside through sealed venting—they're the cleanest, safest option and the one most commonly installed in DeKalb County. Vent-free gas units burn directly into the room without external venting; Tennessee permits them, but they come with strict room-size and oxygen-depletion-sensor requirements, and they add water vapor to the indoor air. For most homes here, a direct-vent unit is the more straightforward and more universally recommended choice—your local dealer can walk through both if you want to weigh the tradeoffs for a specific room.

Plan on an annual inspection, ideally before the first cold snap each fall. A technician checks the burner, pilot assembly, venting, and any gas connections, and cleans the glass and interior—a much smaller job than a wood chimney sweep, but just as important for safe operation. Local gas appliance service providers typically charge $150 to $250 for this visit, and it's worth keeping on the calendar even for propane units that only run occasionally through a mild DeKalb County winter.

Wood is still a strong option here—oak, hickory, and pine are abundant locally, wood stoves run without electricity during ice-storm outages, and fuel costs stay low if you're cutting or buying cordwood locally. Gas trades that self-sufficiency for convenience: instant on-off heat, no ash or creosote to manage, and a cleaner look in a main living space. Given DeKalb County's relatively mild 4A climate and moderate heating degree day count, many homeowners here land on gas for the primary living area and keep a wood stove or fireplace elsewhere as backup—best of both when the power's out and the temperature drops.

If it was installed more than 15 years ago, probably. Older gas fireplaces keep a standing pilot light burning all the time, and that little flame can cost a couple hundred dollars a year. Newer models use pilot-on-demand ignition—the pilot lights only when you use the fireplace and goes out when you turn it off.

An insert does two things: it seals the chimney completely, so you stop losing air you already paid to heat, and it radiates warmth into the room through the firebox and glass. Most add a heat-exchange fan that pulls cool room air underneath, wraps it around the hot firebox, and pushes it back out warm. Your home is more efficient before you've even lit the first fire.

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.

If you're putting a fire in your house on purpose, it's best to work with an expert. Unless you're genuinely experienced in framing, gas line, vent pipe, and the national code on clearances to combustibles, have a professional do it—and ideally the same company that sells you the fireplace, so warranty, service, and liability all live under one roof.
