Wood-to-Gas Fireplace Conversion in Boerne, TX
Converting wood to gas is engineered work, not just dropping in a burner: the flue, the damper, and the gas supply all change at once. We size or reline the flue to prevent condensing and back-draft, lock the damper open to code, and run a BTU-correct gas line with a sediment trap and shutoff. The line is pressure-tested before first flame, and commissioning closes with a leak test and an ambient CO check — the conversion is verified safe by measurement before it's handed over. Serving Boerne (3 ZIP codes, 20k residents) and surrounding neighborhoods with same-week scheduling.
Wood-to-Gas Fireplace Conversion in Boerne
A wood-to-gas conversion changes your wood-burning fireplace to gas — a vented gas log set, a sealed direct-vent insert, or vent-free — handled as an engineered project, not just "add a burner." The appliance swap is simple; the venting changes, code damper lock, gas line, and CO verification around it are what make a conversion a clean, lasting system instead of a hazard behind a pretty flame. Every one is commissioned on instruments before handoff.
Local dossier · Boerne, TX
Boerne was settled by Germans who squared Hill Country limestone by hand, and the town still holds work from that first generation — thick stone walls, lime-bedded joints, chimneys built like the mason expected his grandchildren to check on them. Out here the enemy is mostly heat: caliche-dry summers that swing thirty degrees overnight, expanding mortar all afternoon and contracting it by dawn. That daily cycle, more than rain, is what opens joints in Hill Country stone. The newer side of Boerne is different work — stone veneer over wood framing, factory flues, thin stone glued where thick stone used to stack — and it needs caps, chase covers, and flashing more than it needs a trowel. We handle both, and we don't confuse them. On the old stock, the craft question is matching: new limestone against 150 years of patina, fresh lime mortar against joints that have weathered since Reconstruction. We'll be straight with you — no stone patch matches on day one. Anyone promising invisible stonework the afternoon they leave is selling something. We cut the stone right, match the mortar's strength and sand, tool the joint to the original profile, and let the weather finish the blend the way it always has. That's how Boerne's masonry got old in the first place.
Kendall County Courthouse
Why this matters in Boerne
Boerne is a historic Hill Country town in Kendall County — a German-rooted Main Street and luxury Cordillera Ranch estates — so the inspection documents period masonry repointing and clay-liner condition, large custom-home fireplace status, and rural spark-arrestor compliance. That local stock is exactly why our Boerne crews tailor wood-to-gas fireplace conversion to the homes here — not a generic checklist.
Common signs in Boerne homes
- Tired of hauling firewood, ash, and cleanup
- Want real-fire ambiance with a wall switch
- You want to turn a heat-losing open fireplace into a zone heater that actually warms the room.
- The existing wood firebox is sound, but you'd rather burn a cleaner fuel.
Wood-to-Gas Fireplace Conversion in Boerne (Kendall County) — what's local
Boerne sits in Kendall County (county seat: Boerne). Affluent Kendall County sets historic Boerne masonry beside large custom-home fireplaces and rural spark-arrestor work. We grade each system before certifying it safe to burn. For wood-to-gas fireplace conversion that means our Boerne crew sizes up the local housing stock before quoting — and follows Kendall County permit requirements for any work that needs an inspection sign-off.
Climate & code file · Greater San Antonio
San Antonio is a dozen chimney markets stacked in one city, and the only thing that holds them to one standard is the inspection. A century-old King William Victorian stack, a 1970s ranch firebox off Loop 410, and a 2015 Stone Oak prefab are three different systems with three different failure modes — so each gets the same diagnostic protocol and its own documented condition rating, not a one-size quote. What makes the metro specific is light annual burn and long idle seasons: a handful of fires across a short, mild winter, then nine months unused, which is exactly when undetected damage compounds.
The rare hard freeze on porous stone
A Feb-2021-class freeze is the limestone killer: water already sitting inside porous stone expands and pops the face, and a Level 2 scan exists to catch the cracked tile and open joints it leaves. The defense is verification before the cold — confirm the stone is dry and sound, then seal it with a vapor-permeable siloxane repellent, never a film-forming coating that traps moisture inside and accelerates the spalling at the next freeze.
Limestone & lime mortar — the one that matters most
Before any repointing on older Boerne masonry, the inspection identifies the original mortar — because soft limestone laid in a breathable high-lime mix can't be patched with hard gray Portland without driving the cracking into the stone face. The Portland is harder than the stone, transfers stress into it, and converts a repointing job into a stone-replacement job. We test and color-match the existing mix on record so the repair moves with the wall through every heat-and-freeze cycle.
Cedar (Ashe juniper)
In Boerne the cedar load is a documented fire-safety variable: Ashe-juniper needles and December–February pollen pack spark screens and crown washes, and a clogged cap is logged as both a draft fault and a fire-screen breach. The cap is cleared and inspected every sweep. On wood-burners the report sets the sweep interval to cedar's hot, resin-heavy burn — it glazes a flue far faster than seasoned oak — instead of defaulting to a calendar.
Long dormancy
Nine idle months, then a hard six-week burn, is enough time for a Boerne flue to take on a nest, collect debris, and hide a hairline crown crack the homeowner never sees. The pre-season sweep-and-scan exists to verify all three are clear and documented, so the first cold-front fire lands on a flue confirmed safe and code-ready rather than assumed to be.
Code note · Greater San Antonio
South-Texas / Hill-Country code reality the inspection is held to: porous historic stone is sealed only with a vapor-permeable siloxane repellent — never a film-forming coating — and the cracked-tile and open-joint damage a Feb-2021-class freeze leaves is exactly what a documented Level 2 scan is run to find and rate.
Built to code · Wood-to-Gas Fireplace Conversion in Boerne
Wood-to-Gas Fireplace Conversion is held to published national standards no matter the city. Our Boerne crew builds to these and documents the work; the locally-adopted code edition and permit requirements are confirmed with Kendall County's authority on every job.
- Damper permanently locked open — One rule is non-negotiable on a vented gas log conversion. The damper gets permanently clamped open or its plate comes out entirely, so a closed damper can never trap combustion products above a live gas flame.
- Flue relined / sized for gas — Swap the fuel and you swap the flue-gas temperature, volume, and acidity along with it. That is why the masonry flue is relined or downsized with a correctly-rated gas liner per NFPA 211, so it cannot condense, corrode, or back-draft.
- Gas connection (NFPA 54) — Sizing the gas drop to the appliance BTU load, fitting the NFPA 54 sediment trap and shutoff, and pressure-testing by manometer all happen before any flame is lit.
- Sealed insert: positive connection — From the appliance collar all the way to the cap, a sealed direct-vent insert gets a positive liner connection. Venting it into an open flue invites condensation and back-drafting, so that shortcut never passes here.
- CO check + ODS verification — During commissioning we take an ambient CO reading with the unit in operation, and on a vent-free conversion the oxygen-depletion-sensor (ODS) pilot is verified as well.
Scoped from a graded inspection
At Texas Chimney Experts, a wood-to-gas fireplace conversion is never guesswork. We scope every job from a graded, photographed inspection first — the NFPA 211 level the evidence calls for — so the work is matched to what your flue and masonry actually need, with the report to prove it. The documented inspection is the record the wood-to-gas fireplace conversion is built on.

Wood-to-Gas Fireplace Conversion in Boerne — FAQ
I want to convert my wood fireplace to gas. What is actually involved in that?
Far more than a burner swap. The flue gets sized or relined for gas service, the damper locked open as code requires for vented log sets, and a BTU-correct gas line installed with a sediment trap, then pressure-tested before any flame is lit. A CO check afterward confirms safe operation. That complete sequence is the difference between a conversion that merely lights and one that holds up.
Between gas logs, a sealed insert, and electric, which one should I pick?
Start from how you actually plan to use the room. Vented gas logs deliver the most convincing stand-in for a real open fire; a sealed direct-vent insert wins on heat output and efficiency; electric eliminates maintenance and fuel entirely. Our recommendation matches the conversion to that use, not to the largest invoice we could write.
If I am switching to gas, why does the flue need work when the chimney is already there?
Gas exhaust runs at a different temperature, volume, and acidity than the wood fire your chimney was sized for. Push it into an oversized or mismatched flue and you get condensation, corrosion, and back-drafting. Relining or downsizing the flue to match the new appliance is what makes the conversion safe and clean, and it is a requirement, not an option.
Can I convert back to wood later if I change my mind?
Frequently, yes — the answer depends on what your conversion required. A removable log set reverses easily; a built-in sealed insert with a permanent liner does not. Before you commit, we spell out exactly how reversible your specific configuration is, so the choice gets made with the facts on the table.
Is a vent-free gas conversion a good idea?
In the right space, used for supplemental heat, it can be a reasonable choice: vent-free units run an oxygen-depletion-sensor burner and require no chimney at all. The trade-off is real, though — the room absorbs the added humidity and combustion byproducts. We give you a straight assessment of where a vent-free unit fits and where a vented or sealed unit is the sounder answer.
Can you match new limestone to the weathered stone on my older Boerne house?
We can match the stone's bed, color range, and cut, and we match the mortar's strength, sand, and joint tooling. What nobody can rush is patina — weathered limestone earns its color over decades of sun and rain. A proper patch starts close and blends within a few seasons. We'll show you photos of our older repairs so you can see how the blend actually ages.
Do Hill Country chimneys really need freeze protection?
Yes, in a Hill Country way. Boerne only gets a few hard freezes a year, but they usually land on masonry that's been baked and micro-cracked all summer, and they tend to arrive wet. Water sitting in an open joint that freezes overnight does more damage here than a month of steady northern cold. Sound joints and a crowned, capped top handle it. That's the whole game.
My new build has a stone chimney — does it need masonry maintenance?
Check what's under the stone first. Most new Boerne builds are thin stone veneer over a framed chase with a factory flue, so there's no structural masonry to point. What those need is a fitted chase cover, a solid cap, and regular flashing checks, because water ruins them faster than anything else. If you've got true full-bed stone, that's a different story, and we treat it like one.
