Custom Masonry Fireplace Build (Rumford) in Boerne, TX
This is the showpiece project — a from-scratch masonry fireplace, including the tall, shallow Rumford designs prized for both their elegant proportions and radiant heat, built to be the heart of the room. We design the firebox geometry, throat, and smoke chamber to the exact ratios that make a fireplace draft, laid in firebrick and refractory mortar on a code-depth footing, finished with a proper overhanging crown and outside combustion air.

Serving Boerne (3 ZIP codes, 20k residents) and surrounding neighborhoods with same-week scheduling.
Custom Masonry Fireplace Build (Rumford) in Boerne
A custom masonry fireplace build is a from-scratch firebox, smoke chamber, flue, and crown laid in firebrick and refractory mortar — including the tall, shallow Rumford designs prized for radiant heat. Get the firebox geometry, throat, and smoke chamber even slightly wrong and you've got a beautiful centerpiece that smokes the room every time. We engineer the ratios so it drafts correctly the first time and craft it to last generations.
Local dossier · Boerne, TX
Out in Kendall County the fireplace usually has to hold its own against a view, and that changes how we design it. Boerne great rooms run tall — vaulted ceilings, limestone walls, windows aimed at the hills — so the fireplace is less a feature on a wall and more a piece of architecture: full-height stone chases, heavy timber mantels, fireboxes scaled up so they don't disappear at twenty feet. The town's German settlers built in rock starting in 1849, and the newer custom homes still speak that language. Engineering follows the ceiling height. A tall chase means a long flue run, and long runs need real draft math or the room smells like smoke every cold morning. Acreage properties off the gas grid run propane, which changes valve, orifice, and venting specs — details that get missed when a fireplace is treated as decor. Outdoor rooms are half our Boerne conversations, and Hill Country wind is a genuine design input for where a firebox can face. One thing we'll say plainly: a twenty-four-foot stone chimney is beautiful and expensive, and sometimes the budget does more good in the firebox and the mantel than in the stack. Every build, indoor or out, finishes permitted where required, code-checked always, and photographed for the file.

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. Period masonry repointing and clay-liner relining meet large custom-home fireplace work and rural spark-arrestor service. On every one, the hearth is the visual anchor of the living space — and we service it like one. That local stock is exactly why our Boerne crews tailor custom masonry fireplace build (rumford) to the homes here — not a generic checklist.
Common signs in Boerne homes
- You want a genuine masonry fireplace that throws real heat, not a prefab box on a wall
- A new build or remodel where the fireplace is meant to anchor the whole room
- You want a Rumford for radiant warmth, built to the proportions that make it work
- An earlier masonry fireplace that smokes the room because its geometry was wrong

Boerne sits in Kendall County (county seat: Boerne). Kendall County's affluent Hill Country setting pairs historic Boerne masonry with large custom-home fireplaces and rural spark-arrestor work. For custom masonry fireplace build (rumford) 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 not one fireplace market — it is a dozen of them stacked inside one city, and Space Fireplace Services serves them all to one unvarying standard. A century-old masonry hearth on a King William Victorian, a 1970s ranch firebox off Loop 410, and a builder-grade prefab in a 2015 Stone Oak subdivision are three completely different rooms built around three completely different fireplaces, and what makes the metro specific is the combination of light annual burn and long idle seasons — most homes light a handful of fires across a short, mild winter, then sit unused for nine months.
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. The best defense is keeping water out of the masonry before the cold arrives — seal the breathable stone with a vapor-permeable siloxane repellent, never a film-forming coating that traps moisture inside and accelerates spalling at the next freeze.
Limestone & lime mortar — the one that matters most
If your Boerne chimney is older Hill-Country masonry, do not let a generalist repoint it with hard gray Portland. Soft limestone was laid in a breathable, high-lime mix that flexes with the stone; modern Portland is harder than the stone around it, so it transfers stress into the limestone and drives the cracking into the face — turning a repointing job into a stone-replacement job. We read the existing mortar, match its composition and color, and repoint so the repair moves with the wall through the heat-and-freeze cycle. That's the question budget crews don't even know to ask.
Cedar (Ashe juniper)
Cedar needles and the heavy December–February pollen pack into spark screens and crown washes — a clogged cap is a draft problem and a fire-screen failure at once. We clear and inspect the cap on every sweep. On wood-burners we also flag cedar's hot, fast, resin-heavy burn: it glazes a flue far quicker than seasoned oak, so a cedar-burning Boerne home needs a tighter sweep interval, not the generic annual default.
Long dormancy
A Boerne flue may sit unused for ten months, then get lit hard for six weeks — long enough for animals to nest, debris to collect, and a hairline crown crack to go unnoticed. A fall sweep-and-scan before the short burning season means your first cold-front fire is on a verified, clean, code-ready flue.
Code note · Greater San Antonio
South-Texas / Hill-Country code reality: porous historic stone is sealed only with a vapor-permeable siloxane repellent (never a film-forming coating), and a Feb-2021-class freeze event is the regional benchmark for the cracked-tile and open-joint damage a Level 2 scan exists to catch.
Built to code · Custom Masonry Fireplace Build (Rumford) in Boerne
Custom Masonry Fireplace Build (Rumford) 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.
- Rumford drafting ratios — Draft in a masonry fireplace comes down to proportion: opening-to-flue area, throat dimension, smoke shelf, and smoke-chamber slope all have to relate correctly, and that is the geometry we build to so the firebox pulls cleanly from the first fire.
- Overhanging crown + drip edge — Our poured crowns are formed to overhang the brick and carry a drip edge, so for the life of the chimney rain sheds clear of the masonry instead of running down the face.
- Outside combustion air — A tightly built home benefits from a dedicated outside-combustion-air duct, recommended practice and required by some local codes, which lets the firebox pull makeup air from outdoors rather than depressurizing the house and smoking.
- Smoke-chamber parging — Following NFPA 211 smoke-chamber practice, the corbeled smoke chamber is parged smooth and symmetric, which streamlines the draft and helps it resist creosote buildup.
Scoped from a graded inspection
At Space Fireplace Services, a custom masonry fireplace build (rumford) 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 custom masonry fireplace build (rumford) is built on.

Custom Masonry Fireplace Build (Rumford) in Boerne — FAQ
Why do some brand-new masonry fireplaces still smoke?
Nearly always the geometry is off: an opening mismatched to the flue, a badly formed throat, or a rough, asymmetric smoke chamber. In our builds those ratios are engineered to spec and the smoke chamber is parged smooth, which is why the fireplace draws cleanly from its first fire. Draft comes down to physics, and the build has to respect it.
What sets a Rumford fireplace apart, and is it worth the cost?
Tall, shallow, and finished with angled covings, a Rumford throws far more radiant heat into the room than a deep conventional box. If you want a hearth you actually gather around for warmth rather than one you only watch, it earns its keep, provided the proportions are built correctly. Getting those proportions right is precisely what we specialize in.
Do I need an outside air intake for a new fireplace?
Where the home is tightly built, and wherever code requires it, yes. A dedicated outside-combustion-air duct feeds the firebox makeup air from outdoors, so the fire never depressurizes your living space or pushes smoke into the room. We design it into the build from the start rather than bolting it on later.
How long will a properly built masonry fireplace last?
When the footing, firebox, smoke chamber, flue, and crown are each built to spec, generations is the honest answer. The failures people point to, cracked fireboxes and crowns gone bad, trace back to structural shortcuts, exactly what our engineered build is designed to rule out.
Is a permit and inspection part of the job?
Always. Our team pulls the build permit, coordinates the rough-in and final inspections, and documents the finished system. A fireplace meant to be the centerpiece of a home deserves to be on the record, and that record protects your appraisal and your insurance.
We're on propane outside Boerne — does that limit fireplace choices?
Not much. Nearly every unit we sell has a propane conversion or a factory propane spec — the differences live in orifices, regulators, and vent settings, not in the design catalog. What matters is doing the conversion by the book: Texas requires licensed gas fitters even in unincorporated Kendall County, and we document the whole setup in photos.
Wood or gas for a Hill Country great room?
Honest answer: wood fits the architecture and gas fits the calendar. A masonry wood fireplace with a real stone chase is the Hill Country look, but it's a five-figure structure. A sealed gas unit inside a stone surround reads nearly the same for far less, and it gets lit ten times as often. Come watch both burn before deciding.
Can you build an outdoor fireplace that doesn't smoke out the patio?
Yes, but placement is engineering, not preference. Hill Country evening wind rolls predictably, and an outdoor firebox facing the wrong way will push smoke at the seating no matter how pretty the stone is. We study orientation, firebox depth, and flue height against the roofline before drawing anything. Sometimes a fire pit is smarter — we'll say so.
