Instant Warmth for Sherman's Cold Snaps.

Most gas fireplace projects in Sherman run $3,500 to $8,500. A gas log set or insert into an existing masonry fireplace with a gas line already run to the room sits at the low end. A new direct-vent gas fireplace for a remodel or addition—with framing, venting through an exterior wall, and a fresh gas line from the meter—lands in the middle to upper range. Homes that need a longer gas line run or a propane tank installed for a rural Grayson County property will run higher. A local dealer will give you a firm number after seeing the room.

Yes, and it's one of the most common calls local hearth dealers get in Sherman. Many homes here were built with a traditional wood-burning masonry fireplace that rarely gets used because Sherman's mild winters don't demand daily fires—a gas log set or gas insert turns that same firebox into something you'll actually light on a cold February night without hauling oak or pecan firewood. Vented gas log sets typically run $1,500 to $3,500 installed; a full gas insert with a liner runs closer to $4,000 to $7,000 depending on the model and whether new gas line work is needed.

It depends on where in Grayson County you are. Inside Sherman city limits, Atmos Energy serves most neighborhoods, so if your home already has gas for cooking or water heating, adding a fireplace is straightforward. Outside city limits—in the more rural stretches around Grayson County toward Whitesboro or Denison—propane is the standard fallback, either from an existing tank or a new one set by a local propane supplier. Nearly every gas fireplace, insert, or log set on the market can be configured for either fuel; your installer just sets the correct orifice.

Most will, with the right ignition system. North Texas learned the hard way during Winter Storm Uri in February 2021 how fast a cold snap can knock out the ERCOT grid for days at a time. Gas fireplaces with IPI (intermittent pilot ignition) run on small AA batteries that kick in automatically when the power drops, so the fireplace still lights on demand. Valor units go a step further and generate their own electricity from the pilot's thermocouple, with no batteries needed at all. If backup heat during an outage matters to you, ask your local dealer about the ignition system before you buy.

A gas log set drops into an existing wood-burning masonry fireplace and mimics a real wood fire—it's the least expensive option and the most common upgrade in older Sherman homes. A gas insert also fits into an existing firebox but is a sealed, high-efficiency unit that actually heats the room, using your chimney (with a liner) as the vent path. A gas fireplace is a fully built-in unit for new construction or a remodel where there's no existing masonry fireplace to work with. For most homes here with a fireplace that's rarely used because it doesn't put out real heat, an insert or log set is the right call.

Yes—the City of Sherman requires a building permit for the appliance installation and a separate gas permit for any new gas line work, and a licensed gas-fitter has to handle that piping. Most established hearth dealers pull these permits as part of the job, so you're not coordinating the inspection yourself. If you're outside city limits, check with Grayson County directly, since permit requirements can differ from the city's process.

Vented (direct-vent) units pull combustion air from outside and exhaust it back outside through sealed venting—they're the safest option and put out real, sustained heat. Vent-free gas log sets and fireplaces burn directly into the room without any external venting; they're legal in Texas and popular in Sherman for retrofitting an existing masonry fireplace that has a damaged or hard-to-line chimney, but they come with room-size minimums and an oxygen depletion sensor requirement, and they add moisture to the room. For a fireplace you'll use often or for real heat on a cold front, direct-vent is the better long-term choice. For occasional ambiance in a fireplace you already have, vent-free log sets are a common, budget-friendly fix.

Plan on an annual inspection, ideally in the fall before the first real cold front comes through. A technician checks the burner, pilot assembly, gas connections, and venting, and cleans the glass and interior—a much smaller job than a wood chimney sweep, but still important since a lot of Sherman units sit unused for months at a time between cold snaps. Local gas appliance techs typically charge $125 to $225 for this visit.

Wood heat isn't really a fit here—with Sherman's mild winters and such a light overall heating load, hardly anyone relies on a wood stove for primary heat, even though oak, pecan, and mesquite are all locally available and popular for grilling and smoking. Electric fireplaces, run through Oncor or Texas-New Mexico Power at around 13.8 cents per kWh, are a low-cost, no-venting option for ambiance or a single room, but they don't put out the heat you'd want during a hard freeze. Gas splits the difference: it's the standard choice for homeowners who want real backup heat during an Arctic front and a fireplace they'll actually use the rest of the year.

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.

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.

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.

It's a visit where a hearth professional measures your space, confirms the model you picked actually works in your home, and walks the specs—framing, gas line, venting, finish work—before anything is ordered. Some details you just can't know until you see the house. Never make a down payment without one; it's the single most-skipped step that burns buyers.
