Keep Your Family Warm and Safe—No Matter What

Not as a primary heat source—with only about 1,916 heating degree days a year and winter lows averaging 37°F, the vast majority of Cross Mountain homes rely on central HVAC year-round. When homeowners here do install a wood-burning fireplace or insert, it's almost always for ambiance during gatherings, the visual appeal in a custom Hill Country build, or as occasional backup heat rather than daily use. If you're set on wood, know that you're in a smaller pool of local demand than, say, a Bozeman or Duluth homeowner—but qualified installers do serve this niche around San Antonio.

Because wood heat is a specialty request rather than the local default, pricing tends to vary more here than in cold-climate markets with high installer volume. Expect a masonry-to-insert conversion or a new zero-clearance wood-burning fireplace to land in the same broad national ballpark—roughly $3,500 to $9,000 depending on the unit, chimney work, and hearth requirements—but get a firm quote from a local dealer, since fewer San Antonio-area installers specialize in wood compared to gas. Our free Project Guide & Parts List will spell out the parts and installer recommendation specific to your home before you commit.

Cross Mountain is unincorporated Bexar County, and much of the surrounding area falls within San Antonio's extraterritorial jurisdiction, so permit requirements depend on exactly where your property sits. Some unincorporated Hill Country parcels have limited county building code enforcement compared to inside San Antonio's city limits. Rather than guess, a local hearth dealer who regularly installs in the 78255/78256 corridor will know which jurisdiction applies to your address and pull whatever permit is required—that coordination is part of what you get when we match you with a trusted installer.

All three are common in the Hill Country and all burn reasonably well once properly seasoned. Oak is the local favorite for fireplace use—dense, long-burning, and widely available since it's also the region's dominant hardwood. Pecan burns hot and clean with a mild sweet smell, a byproduct of the area's pecan orchards. Mesquite is prized for barbecue but burns fast and hot with more resin, so it's better mixed with oak for fireplace use than burned alone. Whatever you choose, make sure it's seasoned at least 6-12 months—green mesquite and oak both smoke heavily and build creosote fast.

There's no national forest land near San Antonio, so unlike wood-heating regions out West, you won't find Forest Service cutting permits here. Firewood in the Cross Mountain area comes from local tree services, ranch clearing operations, and Hill Country firewood suppliers who sell seasoned oak, pecan, and mesquite by the rack or cord, typically delivered. Given how infrequently most local households burn, buying a small seasoned batch as needed is usually more practical than stockpiling a full winter's supply the way a cold-climate household would.

Bexar County doesn't carry the winter wood-smoke non-attainment status that some Western cities deal with, so there's no seasonal curtailment program restricting fireplace use here. That said, Central Texas does see periodic outdoor burn bans during drought conditions—those are aimed at brush and yard debris fires, not indoor wood-burning fireplaces, but it's worth checking current Bexar County burn ban status if you're also planning outdoor fire use on your property.

It's one of the more common reasons Cross Mountain homeowners give for wanting one. When the ERCOT grid failed in February 2021, parts of Bexar County went days without power in freezing temperatures, and homes without any non-electric heat source had no fallback. A wood-burning fireplace or stove doesn't depend on the grid at all—light it with a match and it works. If backup heat is your main motivation rather than daily ambiance, ask your local dealer about a freestanding wood stove over an open fireplace; stoves radiate far more usable heat per log, which matters if you're trying to keep one room livable during a multi-day outage.

For most homes here, gas is the more practical everyday choice—natural gas and propane service are both standard in the area, gas fireplaces light instantly, and there's no wood storage or ash cleanup to deal with in a climate where you might only use it a handful of nights a year. Wood makes more sense if you specifically want the ambiance of a real fire, the rustic Hill Country look, or a heat source that works without electricity during grid outages. Some homeowners split the difference: a gas log set for everyday convenience and a separate wood-burning option elsewhere on the property.

Even light use warrants an annual inspection, per CSIA guidelines—infrequent burning doesn't eliminate creosote risk, and a chimney that sits unused for months can also develop animal nests, debris blockages, or moisture damage between uses. Given how few burns a typical Cross Mountain fireplace sees compared to a cold-climate home, a single annual sweep and inspection before your first fire of the season (often around the holidays here) is usually sufficient rather than the mid-season cleanings a primary-heat household might need.

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.

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.

Yes—by creating a comfort zone. A furnace heats every square foot of the house just to warm the one room you're in; a gas fireplace on low burns roughly a sixth of the gas a typical furnace does. Set the furnace around 55–60 degrees as a baseline, then heat the rooms your family actually uses. Families who heat this way commonly save $20–$60 a month.

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.
