Chase Cover Replacement in Boerne, TX
A pooling, rusted chase cover is the documented entry point for thousands in hidden firebox and framing damage — water sits where it should shed. We measure the chase precisely and fabricate a stainless or copper cover to fit, with the slope, overhang, and sealed flue-collar openings that drain instead of holding water — no rust-prone galvanized. The seal and the drainage are verified on install, so the new cover is proven to shed rather than re-create the problem it replaced. Serving Boerne (3 ZIP codes, 20k residents) and surrounding neighborhoods with same-week scheduling.
Chase Cover Replacement in Boerne
A chase cover is the metal top pan that caps a framed (prefab, factory-built) chimney chase and sheds water around the flue collars — the prefab equivalent of a masonry crown. On most homes the original is builder-grade galvanized steel, which rusts through and funnels water straight down the chase onto the firebox and framing. Failed covers are replaced with custom-fabricated stainless or copper, measured to fit and detailed to drain — the rust streaks down the siding being the early visible evidence of the failure.
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 chase cover replacement to the homes here — not a generic checklist.
Common signs in Boerne homes
- Rust streaks running down the siding from the top of the chase
- Water staining at the firebox or ceiling below
- A top pan on a prefab chimney that's visibly rusted, dented, or holding standing water.
- A flat cover holding standing water after rain
Chase Cover Replacement 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 chase cover replacement 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 · Chase Cover Replacement in Boerne
Chase Cover Replacement 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.
- Sloped to shed water — Think of the chase cover as the prefab counterpart to a masonry crown. The replacement is formed with a slope so water drains off instead of ponding, because a flat pan holding standing water is exactly the failure being corrected.
- Overhang + sealed collars — Neither the edges nor the penetrations get the chance to become the next leak: the new cover carries a perimeter overhang, and its flue-collar openings are correctly sized and sealed.
- Cricket where width warrants — Wide chases, and any chase with a ponding history, get a welded cricket or diverter to route runoff around the flue collars. The IRC applies the same water-management logic to a roof cricket behind a chimney.
- Class A clearance preserved — Around the factory-built (Class A) flue pipe, the collar openings preserve the manufacturer's required clearance; closing the air gap the listing requires is a defect we will not build into a cover.
Scoped from a graded inspection
At Texas Chimney Experts, a chase cover replacement 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 chase cover replacement is built on.

Chase Cover Replacement in Boerne — FAQ
How does a chase cover differ from a crown?
They protect two different constructions. A crown is poured masonry capping a brick chimney; a chase cover is the metal top pan on a framed, factory-built (prefab) chimney. When your chimney is a boxed-in chase rather than solid brick, the chase cover is what stands between weather and structure — and on most homes it is builder-grade galvanized, which rusts.
How do I know my chase cover has failed?
Rust streaks running down the siding from the top of the chase are the telltale sign, often paired with water staining at the firebox or the ceiling. Once a galvanized cover rusts through, it stops shedding water and starts funneling it down the chase. Streaking means the metal has already failed, and replacement needs to happen before the leak reaches the structure.
Why choose stainless or copper over another galvanized cover?
Galvanized is exactly what failed the first time, so buying another galvanized cover restarts the same countdown. Stainless steel outlasts it by decades, and copper adds both longevity and a finished appearance. Trading rust-prone metal for corrosion-resistant metal is what turns a recurring leak into a repair made once.
My chase cover ponds water — can that be fixed?
Ponding is a fabrication problem, and fabrication is the fix. The new cover gets a proper slope, and on wide chases or ones with a pooling history we weld in a cricket or water-diverter so runoff sheds away from the flue collars. Drainage decides how long the metal lasts.
What if water already got into the chase?
Checking for it comes standard. Water that has already reached the firebox or framing gets traced and treated as damage in its own right, because a new cover installed over an active problem only conceals it. What sits beneath the old cover gets verified before the replacement goes on.
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.
