Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Cap & Crown Across San Antonio
If you need a chimney cap replaced or a cracked crown repaired in San Antonio, here’s the direct answer: cap replacement typically runs $275-$650 depending on the flue type and cap material, while crown repair and coating usually lands between $450 and $900. Most jobs are completed in one visit, and we give you a written price before any work starts. You can reach us at (980) 580-8641 to schedule a camera-scan inspection anywhere in San Antonio.
Emberly Chimney Cleaners works across the full span of San Antonio housing, from limestone masonry stacks in King William to factory-built chases in Alamo Ranch and Stone Oak. We know which chimney systems hold up to Bexar County’s humidity and which ones fail after a couple of freeze-thaw cycles. And we know something most national outfits miss: in San Antonio, the legal timing of cap and crown work matters as much as the weather.
Why Emberly Chimney Cleaners Is San Antonio’s Preferred Chimney Cap & Crown Company
San Antonio homeowners call us because our inspection standard matches what this city’s housing stock actually requires. We have worked on late-19th century brick chimneys in Monte Vista, 1970s ranch tract fireplaces in the Medical Center area, and post-2010 prefabricated chases across the northwest corridor. The failure pattern on each one is different. A 1970s zero-clearance unit needs a different crown solution than a 2015 builder-grade chase cover. We document the difference with camera footage and photos, then hand you a written scope and price. That’s Clause 1 and Clause 4 of the Haven Standard working together: evidence before recommendation, written price before work.
Every San Antonio job gets a documented photo record, not just a verbal summary. If you’re in San Antonio and want to see exactly what your cap or crown looks like from the rooftop before committing to anything, that’s how we work. Corrine Halstead, who leads our team, set the standard that our techs follow on every visit: name the problem in plain terms, show the evidence, quote the fix in writing.
Our crews serving San Antonio are background-checked and uniformed. License information is on every page, and you get a text when your tech is on the way. Calls go to a live person day or night, not a voicemail tree.
Our Chimney Cap & Crown Services in San Antonio
Cap Installation
Installing a new chimney cap in San Antonio usually costs $275-$550 for a standard single-flue cap, including the cap itself and the mounting hardware. We stock galvanized, stainless, and copper caps from Gelco and Olympia Chimney, and we match the cap to your flue type rather than shimming a generic fit. On older masonry chimneys in neighborhoods like Alta Vista or Tobin Hill, we often find the existing cap is missing entirely or rusted through at the screen. A proper cap keeps rain, leaves, and squirrels out, and in San Antonio it also keeps chimney swifts from turning your flue into a seasonal nursery.
Cap Replacement
Cap replacement in San Antonio runs $300-$650, with the higher end covering multi-flue caps and custom sizes on older limestone chimneys where standard stock caps do not fit the flue tile dimensions. We see a lot of corroded caps on post-2000 homes along Culebra Road and the 1604 loop, where the original builder cap was thin galvanized steel. After a few humid summers and an occasional hard freeze, the seams split and the cap starts pulling away from the crown. We replace the failed cap and photograph the finished install from the roofline so you can see it without climbing up there yourself.
Crown Repair
Crown repair in San Antonio typically costs $450-$750. That covers patching spalled concrete, filling hairline cracks, and re-sloping the crown surface so water sheds away from the flue instead of pooling against it. Homes built in the 1960s through the 1980s across neighborhoods like Castle Hills and the Northeast Side often have uncoated concrete crowns that were poured too thin at the edge. San Antonio’s freeze-thaw cycles, while infrequent, are enough to pop chunks off a thin crown. We repair the crown before water works down behind the masonry and into the smoke chamber.
Crown Coating
A crown coating in San Antonio runs $500-$900 depending on crown size and material condition. We use Gelco crown coat, which is a flexible elastomeric sealant that moves with the concrete instead of cracking away from it. That matters here because San Antonio’s climate swings between long humid stretches and sudden hard freezes. The coating stays bonded while the underlying crown expands and contracts. On ranch-style homes where the crown is exposed and visible from the street, the coating also gives the chimney a clean, sealed look rather than a patchwork repair.
Multi-Flue and Custom Caps
Multi-flue caps in San Antonio run $550-$950 installed. Custom caps, including powder-coated or copper caps sized to a specific flue layout, run $750-$1,500. We have a Free Second Opinion policy on any written estimate, so if another company has quoted you a custom cap and you want the measurements verified, bring us the quote. We will put our number in writing before we ask for a deposit.

BeforeAfterTrusted Brands We Service in San Antonio
We install caps and crown materials from Gelco, Olympia Chimney, and Copperfield. These are the brands we trust after 15 years of seeing what fails in San Antonio’s climate. Gelco crown coat holds up to Bexar County’s humidity and occasional hard freezes without separating. Copperfield caps work well on limestone and brick chimneys where a galvanized cap would look wrong from the street. We keep a working inventory of common cap sizes and flue tile dimensions on our San Antonio service trucks, which means a straightforward cap replacement on a standard flue rarely requires a second trip. If you have a factory-built zero-clearance fireplace from the 1990s or 2000s, we match the manufacturer-specific cap rather than forcing an aftermarket part that compromises the chase.
Common Chimney Cap & Crown Problems We See in San Antonio Homes
- Chimney swift nesting in uncapped flues: From April through October, chimney swifts occupy open flues across San Antonio, and because they are federally protected under the Migratory Bird Treaty Act, you cannot legally disturb an active nest. If your chimney lacks a cap during nesting season, your only legal option is to wait until the birds migrate out, sometime in early fall, then have the cap installed before the next spring.
- Corroded chase covers on factory-built fireplaces: Homes built after 2000 in neighborhoods like Alamo Ranch, Westover Hills, and Stone Oak often have prefabricated chases with thin metal chase covers. San Antonio’s long humid stretches, followed by the occasional hard freeze, cause these covers to rust through at the corners. Water then drips down the chase and onto the drywall ceiling below, which is usually how homeowners discover there is a problem at all.
- Spalled crowns on 1960s-1980s ranch chimneys: The original concrete crowns on many older San Antonio ranch homes were poured thinner than modern code requires. After 40 or 50 years of Bexar County freeze-thaw cycles, the edges crumble. Once the flue liner is exposed to direct rain, the deterioration accelerates, and you start seeing water staining around the fireplace opening.
- Creosote-coated caps and dampers from cold-weather burn bursts: San Antonio homeowners often fire up the fireplace during sudden Arctic fronts using whatever wood is available at the big-box store. Those short, smoky burns with a cold flue produce heavy creosote deposits that coat the underside of the cap and the damper. Then the fireplace sits unused for nine months while the acidic creosote eats into the metal.
Pricing for Chimney Cap & Crown in San Antonio, TX
Here are the actual numbers we quote on San Antonio jobs. A standard single-flue cap replacement runs $275-$550. A multi-flue or custom cap runs $550-$1,500. Crown repair with patching runs $450-$750. Crown coating runs $500-$900. The biggest price driver is flue configuration, meaning how many flues share the chimney and what size tiles you have. Older masonry chimneys with odd-sized flue tiles often need a custom cap, which pushes the price toward the top of the range. A written price is always delivered before any work starts, and you are never asked to commit to a repair before seeing the camera-scan footage of what is actually wrong.

FAQs - Chimney Cap & Crown in San Antonio
No, if there is an active swift nest in the flue, Federal law protects it under the Migratory Bird Treaty Act, and you cannot legally disturb or remove it. The practical window for cap installation on an uncapped flue in San Antonio runs roughly November through March, after the swifts migrate out and before they return. If you call us in April and your chimney has an active nest, we will document it with photos, tell you honestly that the work has to wait, and put you on the schedule for November. If you currently have no cap and it is October, the smart move is to get a free estimate now so the cap goes on as soon as the swifts leave.
Even if you never use the fireplace, your factory-built chase needs a cap because the chase cover and flue termination point are the first things to fail on post-2000 San Antonio homes. The original covers are often thin galvanized steel that corrodes through the seams after a few humid summers and a hard freeze or two. Once the cover fails, rainwater runs down the flue, swifts move into the chase, and the first sign you get is a water stain on the ceiling below the fireplace. A camera-scan inspection can show you whether your factory-built system still has its original cap or whether it is already compromised.
Most cracked crowns on 1970s ranch-style chimneys in San Antonio can be repaired, not replaced. If the crown has a few hairline cracks or chipped edges, we patch the spalled concrete, fill the cracks, then apply a Gelco crown coating over the entire surface. Full crown replacement is only necessary when the crown has deteriorated to the point that large sections are missing or the flue tile is loose. We show you the camera footage before recommending either path, and the written price covers exactly what you need, not a worst-case scenario.
After Winter Storm Uri in February 2021, San Antonio techs saw a wave of chimney caps and chase covers that had corroded from the combination of freezing rain, hard freeze-thaw cycling, and acidic creosote deposits left behind by homeowners burning anything they could find during the power outage. A cap that had been marginal before Uri rusted through at the seams in the following months. If your fireplace sat unused for years before Uri and then went through that week of continuous burning, the creosote from that burst of smoke is still sitting on the underside of your cap, actively corroding the metal. Get a camera-scan inspection and we will show you the condition of the cap before you spend anything on a replacement.
Yes, for two reasons. First, an uncapped flue is open to chimney swifts from April through October, and once they nest, the chimney cannot be cleaned or capped until they leave. Second, rain entering an unused flue still damages the interior masonry and flue liner, especially on older limestone chimneys in central and historic San Antonio neighborhoods. The cost of a cap is far lower than the cost of a flue liner replacement three years from now. Call (980) 580-8641 and we will inspect the cap situation before nesting season starts.
A Local Case That Shows the Pattern
We got called to a 2003-built home in Alamo Ranch where the homeowner had never used the factory-built fireplace. After Uri, they lit it hard for several days and then noticed water staining on the ceiling below the chase. Our tech pulled the chase cover and found a missing manufacturer-specific cap on a DuraFlex flue liner. The prefabricated chase had become a swift roost, and the crown’s Gelco coating was cracked from the 2021 freeze-thaw, letting water run behind the siding and down into the drywall. The total fix ran under $900: a replacement cap matched to the DuraFlex liner, a new chase cover, and a recoat of the crown. The homeowner had no idea anything was wrong until the ceiling stain appeared. That is the San Antonio failure pattern on newer homes, and it is exactly why a camera-scan inspection on a fireplace you never use can save you thousands over a water-damage repair.
