Find the right gas fireplace for your Grayson County home.
From Sherman to Denison to the shores of Lake Texoma, gas fireplaces bring instant ambiance to mild North Texas winters—and reliable backup heat when an ice storm knocks the power out. Find the right unit and connect with a trusted local dealer.
Every Project Starts From One of These Five Situations
Comfort and ambiance, not survival heat.
Grayson County sits in climate zone 3A along the Texoma border, where the winter low averages a mild 34 degrees and the county logs roughly 2,700 heating degree days a year—a fraction of what a place like Fargo, ND or Duluth, MN sees. Sherman and Denison anchor the county's population, with Pottsboro, Whitesboro, Tioga, and Southmayd rounding out the rural stretches near Lake Texoma. Wood heat has deep roots here—the post oak savannah and pecan bottomlands supply plenty of oak, pecan, and mesquite for burning—but in a county where hard freezes are the exception rather than the rule, gas fireplaces have become the default choice for most new construction and remodels, prized more for instant comfort and clean good looks than for keeping a house from freezing.
Atmos Energy runs natural gas service through Sherman and Denison and most of the surrounding incorporated areas, so homes already on the gas grid can usually add a fireplace without much extra plumbing. Out in unincorporated Grayson County—around Tioga, Southmayd, and the Lake Texoma shoreline—propane is the more common fuel, delivered and tanked by regional suppliers. Grayson County has no wood-smoke air quality restrictions or curtailment periods to navigate, which keeps gas installations straightforward from a permitting standpoint. The real draw is the flip-a-switch convenience paired with real backup value: when a February ice storm takes down the grid the way Winter Storm Uri did across North Texas in 2021, a battery-backup gas fireplace keeps one room warm and lit without a generator.

Frequently Asked Questions
How much does a gas fireplace installation cost in Grayson County?
Most gas fireplace installations in Grayson County run somewhere between $3,000 and $8,500, with the spread driven by the unit itself, the venting path, and whether new gas line work is required. A direct-vent insert dropped into an existing masonry fireplace that already has a gas line nearby sits at the lower end. A new build-in fireplace for a remodel, or a propane tank installation for a rural property outside Atmos Energy's service area, pushes toward the higher end. Homes around Sherman and Denison with existing natural gas service tend to install for less than rural properties near Tioga or Southmayd that need a propane tank set and a longer line run. A local dealer can give you a firm number after an in-home look.
Can I convert my existing wood fireplace to gas?
Yes, and it's a common project for the older farmhouses and brick ranch homes scattered across Grayson County that still have a masonry fireplace built for burning oak, pecan, or mesquite. A gas insert slides into that existing firebox and vents through a stainless liner run up your current chimney, so you keep the look of the original hearth while gaining instant on-off heat and no more ash or creosote to manage. Expect the conversion to run $3,500 to $7,500 depending on whether you're on natural gas through Atmos Energy or need to add propane service, and whether the chimney needs relining work before the liner goes in.
Do I need natural gas to install a gas fireplace, or can I use propane?
Either fuel works, and which one you'll use mostly comes down to where you live in the county. Atmos Energy serves natural gas throughout Sherman, Denison, and most of the incorporated areas in between, so if your water heater or range already runs on natural gas, adding a fireplace is a simple tie-in. Once you're out past city limits—around Lake Texoma, Tioga, or Southmayd—propane is the standard, supplied by a regional propane company with either an existing tank or a new tank set as part of the install. Nearly every gas fireplace on the market can be configured for either fuel; your installer just sets the correct orifice and regulator for the gas you have.
Will my gas fireplace work during a power outage?
Most modern gas fireplaces will, which matters in a county that has seen multi-day outages during major ice events like Winter Storm Uri in February 2021. Units with intermittent pilot ignition (IPI) run on a small battery backup that kicks in the moment the power drops, so the fireplace still lights on demand. Valor fireplaces take a different approach—their pilot assembly generates its own electricity through the thermocouple, so there's no battery to remember or replace. For a Grayson County home where an ice storm can take out power for days while temperatures hover in the 20s, that kind of self-powered backup heat in one room is a real asset. Ask your local dealer about the ignition system on any model you're considering.
What's the difference between a gas fireplace, gas insert, and gas stove?
A gas fireplace is a fully built-in unit framed into a wall, typically used in new construction or a full remodel. A gas insert is built to slide into an existing masonry fireplace opening, sealing it up and venting through the existing chimney with a liner—the common upgrade for Grayson County's older brick-hearth homes. A gas stove is a freestanding cabinet-style unit that sits on the floor like a wood stove but burns gas, useful in a room without an existing fireplace or chimney. For most homeowners here with a fireplace they want to upgrade, an insert is the straightforward answer; new rooms or new builds are better suited to a built-in fireplace or freestanding stove.
Do I need a permit to install a gas fireplace in Grayson County?
Yes—a building permit and a gas line permit are typically required, whether you're inside Sherman or Denison city limits or in unincorporated Grayson County, where the county building permit office handles the paperwork. The gas line portion has to be run by a licensed gas-fitter, which is one reason to work with an established local hearth dealer rather than a general handyman—they coordinate the gas work, venting, and inspection as one job instead of leaving you to manage separate trades. Unlike wood-burning installs in parts of the country with winter air quality curtailment, Grayson County has no burn restrictions to work around, so gas permitting here is a fairly clean process.
What's the difference between vented and vent-free gas fireplaces?
Vented (direct-vent) gas fireplaces pull combustion air from outside and exhaust the exhaust gases back outside through a sealed pipe—they're the cleaner, more universally code-friendly option and what most local dealers install by default. Vent-free units burn gas directly into the room with no external venting; they run more efficiently on paper but release some water vapor and trace combustion byproducts into your living space, and they come with strict room-sizing and oxygen-sensor requirements. Texas allows vent-free units, and they show up in some Grayson County installs where running venting to the exterior is difficult, but for most homes here a direct-vent unit is the safer, more commonly recommended choice. A local dealer can walk you through both.
How often should my gas fireplace be serviced?
Plan on an annual inspection, ideally before the cooler months arrive around Sherman and Denison. A certified 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, especially for battery-backup ignition systems you're counting on during an ice storm outage. Most gas appliance service providers in the area charge somewhere in the $125 to $225 range for a standard annual visit.
Gas vs. wood—which is right for my home?
Wood has genuine roots in Grayson County—oak, pecan, and mesquite are all locally abundant, and a wood-burning fireplace or insert works without electricity, which matters during an ice storm outage. But with only about 2,700 heating degree days a year and winter lows that average in the mid-30s, most Grayson County homes don't need wood as a primary heat source the way a colder climate would. Gas offers instant on-off convenience, no ash or creosote to manage, and a consistently clean look, which is why it's become the default for new construction and remodels across Sherman and Denison. If self-sufficiency and the ritual of a real fire matter most, wood is worth a look; if convenience and low-maintenance ambiance are the priority, gas is usually the better fit for this climate.
Why is my open fireplace making my house colder?
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.
What's the difference between an insert and a zero-clearance fireplace?
An insert is a fireplace that slides into a pre-existing wood-burning fireplace—if you don't have one, there's nothing to insert it into. A zero-clearance fireplace is built into a framed wall, which makes it the answer for remodels and new construction. Simple test: existing masonry fireplace means insert; blank or framed wall means zero-clearance.
Can I install a fireplace myself?
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.
How much should I budget for a fireplace?
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.
