Chimney Flashing Repair in Alamo Heights, TX
If water shows up on the ceiling near the chimney, the culprit is almost always the flashing where it penetrates the roof — and a bead of caulk there fails inside two years. We cut new reglets and install proper step plus counter-flashing, the only repair that actually lasts. Because we're already on the roof and reading the whole system, we'll flag anything else up there worth handling in the same trip, so you close out every roof-line leak path at once instead of chasing drips one storm at a time. Serving Alamo Heights (1 ZIP codes, 8k residents) and surrounding neighborhoods with same-week scheduling.
Chimney Flashing Repair in Alamo Heights
Flashing is the metal-and-sealant barrier where the chimney meets the roofline, and it's the number-one source of chimney leaks we get called for. Done right, it uses step flashing, counter-flashing set into the mortar, and a genuine watertight seal — not just a smear of roofing tar that buys a season and fails. Since we're already on your roof for chimney work, diagnosing and rebuilding the flashing is a natural part of the same visit.
Local dossier · Alamo Heights, TX
The oak-shaded blocks of Alamo Heights hold some of the San Antonio area's oldest housing stock — 1920s and '30s masonry with original clay-tile flues, plaster walls, and attics that were never insulated to anything like a modern standard. Homes like these age as a set. The same decades that soften old mortar joints leave the ductwork from a 1980s retrofit leaking into wall cavities, and the dryer vent runs wherever a remodeler could route it, sometimes twenty feet or more. So we treat a Heights house as one system, not five appointments. One crew checks the chimney from crown to firebox, scopes the ducts, clears the dryer run, and measures what insulation is actually left up top. You get a single report with photos, ranked by urgency. To be honest, in a mild San Antonio winter some of what we find can wait, and we'll say so in writing rather than pad the invoice. Deferred isn't ignored, though: a hairline crown crack drinks in every spring storm, and a flue that burns eight nights a year still has to be safe for those eight nights. If your place is within walking distance of The Argyle, it's old enough to have earned one thorough, connected look.
The Argyle
Why this matters in Alamo Heights
Alamo Heights is San Antonio's historic affluent enclave — 1920s-40s Spanish-revival and brick mansions near Olmos Park. The work here is period-correct masonry repointing, clay-liner relining, and crown rebuilds on chimneys approaching a century old. Either way it's one trip: a cross-trained crew bundles the chimney service with the vent and duct work on a single visit. That local stock is exactly why our Alamo Heights crews tailor chimney flashing repair to the homes here — not a generic checklist.
Common signs in Alamo Heights homes
- Water stains on the ceiling or wall near the chimney
- Rusted, lifted, or loose metal at the chimney base
- Visible roofing tar 'repairs' that keep failing
- Damp or musty smell in the attic near the chimney
Chimney Flashing Repair in Alamo Heights (Bexar County) — what's local
Alamo Heights sits in Bexar County (county seat: San Antonio). Bexar County is San Antonio's home county, with some of the oldest masonry in Texas. Clay-liner cracking and repointing dominate our crews' work alongside suburban prefab jobs. For chimney flashing repair that means our Alamo Heights crew sizes up the local housing stock before quoting — and follows Bexar County permit requirements for any work that needs an inspection sign-off.
Climate & code file · Greater San Antonio
San Antonio is not one chimney market — it is a dozen stacked inside one city, and Texas Service Experts covers all of them with one cross-trained crew that brings the whole house under a single appointment. A century-old masonry stack 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 different systems, but every one of them shares a house with a dryer vent and a duct run — and the metro's light annual burn and long idle seasons mean all of it sits unused for nine months and wants checking together, in one window, not across three trades.
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. Booking the seal alongside the fall sweep and cap check means one crew weatherproofs the whole stack before the cold, instead of a separate trip once the damage shows.
Limestone & lime mortar — the one that matters most
If your Alamo Heights 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. The crew that reads the existing mortar, matches its composition and color, and repoints to move with the wall is the same crew already on site for the sweep and the cap — so the masonry, the flue and the venting are handled together, not by three callouts. 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. The same resinous debris finds the dryer vent and the gutters, so the crew clears the cap, checks the vent and flags the buildup in one pass rather than sending you back to the phone. 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 Alamo Heights home needs a tighter sweep interval, not the generic annual default.
Long dormancy
A Alamo Heights 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. One fall visit covers it all: sweep-and-scan the flue, clear the cap, and check the vent that's been idle just as long — so your first cold-front fire is on a verified, clean, code-ready system rather than a string of separate pre-season errands.
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 · Chimney Flashing Repair in Alamo Heights
Chimney Flashing Repair is held to published national standards no matter the city. Our Alamo Heights crew builds to these and documents the work; the locally-adopted code edition and permit requirements are confirmed with Bexar County's authority on every job.
- Step + counter-flashing — Done to code, the flashing transition is a two-part assembly. Step flashing weaves course-by-course into the shingles, and counter-flashing sets into a saw-cut reglet in the masonry; a bead of roofing tar is neither of those things.
- Cricket where slope warrants — Wide chimneys and stacks sitting in a roof dead-valley get a cricket, also called a saddle, built on the up-slope side. It steers water and debris around the stack, and it is the accepted fix wherever roof slope and chimney width let water dam against the back wall.
- Watertight, mechanical joint — Counter-flashing gets mechanically set and sealed into a backed reglet reservoir, which keeps the joint watertight as the building moves. Surface caulk, by contrast, pulls away within a season.
Scoped from a graded inspection
With our crew, a chimney flashing repair 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 flashing repair is built on.

Chimney Flashing Repair in Alamo Heights — FAQ
How do I know the leak is coming from the flashing?
Flashing leaks tend to announce themselves as ceiling or wall stains around the chimney, damp or rotted framing in the attic nearby, and rust streaks along the roofline. Because water runs along framing before it ever drips, a sound diagnosis rules out the crown, cap, and masonry before it pins the blame on the flashing.
Can't I just seal it with caulk or roofing tar?
A bead of sealant is a short-term patch that usually cracks and gives out within a season or two. The lasting fix is layered step flashing and counter-flashing woven into the shingle courses and locked into a cut mortar joint, not surface goo smeared over a failed assembly.
What happens if I ignore a flashing leak?
Ongoing water intrusion rots roof decking and framing, soaks insulation, stains drywall, and feeds mold, and it can also eat away at the chimney masonry from the inside. The longer it goes unaddressed, the more hidden structure ends up needing replacement, and the repair cost climbs sharply.
How long does flashing repair take?
Most flashing repairs wrap in a few hours to a day, depending on roof pitch, chimney size, and whether we find rotted decking underneath. Steep roofs and swapping out damaged sheathing add time, and hidden water damage is the number-one reason a job runs longer than quoted.
Does new flashing come with any guarantee it won't leak again?
Reputable installers stand behind their flashing work with a warranty, and properly woven step-and-counter flashing should keep the roofline dry for many years. Before work begins, ask that the quote put the materials, the layering method, and the warranty term in writing.
Can one visit really cover a 1920s Alamo Heights home?
That's the whole design of it. Older homes interconnect in ways separate contractors miss — the chase that carries your original flue often carries duct runs and wiring too, and an uninsulated attic changes how the entire house breathes. We inspect chimney, ducts, dryer vent, and insulation in one pass and write it up as one prioritized report, so you're not reconciling four different opinions.
Our fireplace is original to the house. Is it still safe to use?
Maybe — many pre-war flues here are unlined or have cracked clay tiles, and you can't tell from the hearth. A camera inspection settles it in about twenty minutes. If it's sound, we document that and sweep it. If it needs a liner, we price it plainly and tell you what's safe in the meantime, which is sometimes nothing until it's fixed.
What order should the work happen in an older home?
Inspection first, always — it sets the sequence. Typically: chimney safety items before burn season, attic air-sealing and insulation in spring or summer when it pairs naturally with duct sealing, and the dryer vent the same day as everything else since it takes the least time. Masonry repairs cure best in warm, dry months, so we slot those accordingly.
