Chimney Flue Installation in Boerne, TX
A new flue — clay tile, steel, or cast-in-place — is permitted, code-inspected work, and the sizing is the part that has to be right: the flue is calculated to the appliance's fuel and the chimney's height before any material goes in. We build to IRC and NFPA 211, pull the permit, and carry the job through municipal final inspection. That third-party sign-off, plus our own documentation, is the verification — a flue proven to code, not merely installed. Serving Boerne (3 ZIP codes, 20k residents) and surrounding neighborhoods with same-week scheduling.
Chimney Flue Installation in Boerne
Flue installation fits a flue or liner where a proper one never existed — a new-construction chimney getting its first flue, a newly added appliance needing its own vent path, or an unlined masonry chimney being lined for the first time. It's a first-time install rather than a replacement: there's no failed liner to remove, only a missing flue to build correctly from the start, measured to the appliance and listed to code before anything is set.
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 chimney flue installation to the homes here — not a generic checklist.
Common signs in Boerne homes
- A chimney still being built that needs its first flue set
- A masonry chimney run for years unlined, with no liner ever installed
- A stove, furnace, or fireplace newly added with nowhere for the flue gas to go
- An inspector who wants the flue in place before signing off on the appliance
Chimney Flue Installation 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 chimney flue installation 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 · Chimney Flue Installation in Boerne
Chimney Flue Installation 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.
- UL-1777 listed liner — A first-time flue built as a metal or cast liner has to be a UL-1777 listed system, with the listing documented for the building permit and the inspection; improvised pipe pushed down an unlined stack does not qualify.
- Sized per NFPA 211 / listing — We calculate the flue dimensions from the appliance outlet, the heat output, and the chimney height, checked against the NFPA 211 venting tables and the appliance listing. Sizing done right at install is the difference between a brand-new flue that drafts properly and one that drafts poorly from day one.
- Clay tile bedding (NFPA 211) — Refractory mortar bedding, a plumb set, and the expansion allowance NFPA 211 requires are the three details that keep a new clay-tile flue from cracking on its first heat cycle after the masons' first-time install.
- Clearance to combustibles — Clearance to combustibles is designed into the new flue from the first course, never retrofitted. Interior masonry holds 2 in, exterior holds 1 in per the IRC, and a factory-built chimney holds whatever its listing specifies.
Scoped from a graded inspection
At Texas Chimney Experts, a chimney flue installation 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 chimney flue installation is built on.

Chimney Flue Installation in Boerne — FAQ
When do I need a flue installation versus a reline?
Flue installation applies to chimneys or appliances that don't have a proper flue yet: a new-construction chimney receiving its first flue, a freshly added stove or furnace with no vent path, or an old masonry stack that's been burned unlined for years. Relining is the reverse situation, where an existing liner has cracked or spalled and needs replacing. If there's no liner to remove, it's flue installation; if there's a failed liner to swap out, it's relining.
How do I choose between clay tile, rigid steel, and cast-in-place for a first-time flue?
On a first install you get a clean choice. Clay tile, bedded in by the masons, is the traditional, low-cost option for a new masonry chimney. Rigid stainless is the usual selection for lining an unlined stack or venting a modern appliance, with the alloy matched to the fuel. Cast-in-place suits an unlined masonry chimney that's also structurally weak, since it lines and re-stiffens the stack in a single pour. Your appliance, your fuel, and the chimney itself make the call.
Why is sizing a brand-new flue so critical?
Because there's no existing draft to measure against, and sizing it wrong means the new chimney will never perform correctly. Per NFPA 211, the flue is sized to the appliance outlet, the BTU rating, and the chimney height: an oversized flue can't build draft while an undersized one chokes the appliance, and either way combustion gases spill. Setting a wood stove on an oversized masonry flue is the classic first-install error, and it drives creosote buildup and weak draft.
Does a first-time flue install need a permit and inspection?
Almost always, and it's normally rolled into the building or appliance permit instead of a separate visit, because the flue is part of new construction or the commissioning of a new appliance. We size and document the installation to the NFPA 211 tables and the appliance listing so the inspector can pass a brand-new flue and the appliance can be commissioned.
How long does it take, and can the appliance be used right away?
Clay-tile and rigid-steel flues are ready to use as soon as the installation passes inspection, usually one to two days of work. A cast-in-place flue has to cure before any fire, often a day or more depending on the product and the temperature, so build that wait into your plans if the unlined chimney requires that method.
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.
