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 Flower Mound
Chimney cap and crown work in Flower Mound usually costs between $185 and $890, depending on whether we’re sealing a cracked crown with a Gelco coat or fabricating and installing a custom copper cap on a 1990s prefab flue. Most jobs are completed in a single visit, and we serve every neighborhood in Flower Mound, from The Wellington and Bridlewood to Tour 18 and Chimney Rock. The problem this town faces is specific: roughly 25,000 homes here were built between 1990 and 2005, and nearly all of them use builder-grade zero-clearance fireplaces now at or past their 20-30-year manufacturer service life. The caps and crowns on those units fail from moisture, freeze-thaw cycles, and animal intrusion during long idle stretches, not from daily burning. We photograph what we find before recommending anything. Call (980) 580-8641 and we’ll give you a written price before any work starts.
Key Takeaways:
- Crown repair on a Flower Mound prefab fireplace typically runs $225-$450; custom cap fabrication starts around $385
- Every visit includes a camera-scan inspection under NFPA 211 Level 2, with photo documentation you keep
- Nothing is recommended without camera evidence you can see for yourself
- We cover every Flower Mound neighborhood, with dispatch coordinated from our Dallas-Fort Worth office
- Written price, written scope, and written warranty before anyone picks up a tool
Why Emberly Chimney Cleaners Is Flower Mound’s Preferred Chimney Cap & Crown Company
We’ve photographed more failing caps and spalled crowns in Flower Mound than most companies will inspect in a decade. The reason is simple: this town’s housing stock is aging into a specific window of component failure, and we made camera documentation our default in 2009, years before anyone asked for it. Our Chimney Cap & Crown team has inspected and cleaned more than 38,000 chimneys since then, every one with a written price before work started and a documented photo record when it was done.
Flower Mound homeowners tend to be skeptical of chimney companies, and for good reason. The industry’s worst upselling happens right here, on 25-year-old prefab fireplaces that have barely been used. A tech shines a flashlight, tells you the liner is shot, and quotes $4,000. We won’t do that. Clause 4 of the Haven Standard requires a camera down the flue and a photo record on every visit. If we recommend a cap replacement or crown rebuild, you’ll see the exact crack or rust-through in the photos we hand you. That’s the difference between a chimney company that sells you a story and one that shows you the evidence.
Our Flower Mound customers consistently mention the same thing: the written price came before the work, the tech was uniformed and background-checked, and the phone line was answered by a live person at 9pm when a squirrel started scratching inside the chase. We run live phone support 24/7. When a February cold snap cracks a crown and water starts streaking the drywall, you don’t want a voicemail.
Our Chimney Cap & Crown Services in Flower Mound
Four services make up most of our Flower Mound cap and crown work. Each is quoted at a flat written price, never hourly, and the scope is printed before we start.
Cap Installation
Many Flower Mound homes with 1990s prefab fireplaces still have the original factory cap, which is now rusted thin or gone entirely. We install custom-fit stainless steel and copper caps sized to the flue opening, with 5/8-inch mesh to keep squirrels and birds out during the long idle stretches common in North Texas. In the Wellington of Flower Mound neighborhood, our crew pulled a rusted-out Olympia Chimney cap off a 1998 zero-clearance fireplace flue that had become a squirrel nest site during two winters of disuse. A missing or undersized cap on a rarely used flue means the first fall burn fills the smoke chamber with debris and draws poorly. We fix that before you light it.
Cap Replacement
If the cap is still attached but corroded or warped, replacement is usually straightforward: remove, measure, fabricate or order the correct size, and install with a proper mechanical connection to the flue. We source from Copperfield and Olympia Chimney, and we don’t stock universal one-size-fits-all caps that leave gaps. A cap that doesn’t seat correctly is as bad as no cap in Flower Mound’s wet shoulder seasons, when humidity accelerates rust on exposed metal components.
Crown Repair
This is where Flower Mound’s freeze-thaw problem shows up most clearly. The builder-grade mortar wash crowns poured on 1990s and 2000s prefab units were often too thin, and the February 2021 Winter Storm Uri event split thousands of them across town. What starts as a hairline crack becomes a water path into the firestop and chase. We cut back damaged crown material, rebuild the slope, and apply a Gelco crown coat that flexes through temperature swings. If the damage is cosmetic only, we’ll say that plainly and give you a price to leave it alone until next season.
Crown Coating
For crowns that are structurally sound but showing early spalling, a proper crown coat extends the service life without a full rebuild. We apply Gelco crown coat after surface prep, which seals minor cracks and restores the slope needed for water to run off rather than pool. Given Flower Mound’s mild winters punctuated by hard freezes, this is the highest-value maintenance for a crown that hasn’t failed yet. The crown beneath the Wellington cap we pulled was freeze-cracked from the 2021 cold snap, with hairline spalling spreading down the mortar wash. We cut it back, applied the Gelco coat, and installed a custom copper cap in one visit.

BeforeAfterTrusted Brands We Service in Flower Mound
We work with the components already installed in Flower Mound homes and source replacements from brands built to last two decades or more. Copperfield caps, DuraFlex liners, and Gelco crown coats are standard on our trucks. HeatShield resurfacing materials cover the cases where a crown repair has to extend into the flue pipe itself. Because we buy through Haven’s network, we pass the cost on honestly, and we can quickly match what’s already on your chase. No waiting weeks for a part, no substituting a generic that doesn’t fit a 1998 Majestic or Heatilator flue the way it should.
For Flower Mound specifically, most of the caps we replace are original equipment on zero-clearance units from manufacturers who no longer support the model. We fabricate custom caps to match the flue’s exact exterior dimensions, then install with a screen mesh that keeps out the squirrels that exploit idle flues all spring and summer.
Common Chimney Cap & Crown Problems We See in Flower Mound Homes
- Freeze-thaw cracking from severe cold snaps. February 2021’s Uri event cracked otherwise sound crowns on chimneys that had never seen continuous burning. The damage often didn’t show up until spring rain streaked drywall near the chase.
- Thin builder-grade mortar wash crowns. Homes built between 1990 and 2005 in Flower Mound often have crowns poured too thin at the time of construction. Twenty years of expansion and contraction later, they spall and let water reach the firestop.
- Animal intrusion during long idle periods. Birds and squirrels move into flues that see only five to fifteen burns a season. Missing or undersized caps make it easy, and the first fall fire pushes nest debris into the smoke chamber.
- Rusted factory caps on prefab fireplaces. The cheap caps installed at original build are now 25 years old in most Flower Mound homes. They rust through at the seams and start letting rain directly down the flue.
None of these conditions require guesswork to diagnose. When we inspect a Flower Mound chimney cap and crown, the camera footage and still photos show exactly what’s failing and what’s still sound.
Pricing for Chimney Cap & Crown in Flower Mound, TX
Here’s the honest math for Flower Mound’s market. A standard stainless steel cap installation runs $185-$320. A custom copper cap on an older prefab flue runs $385-$650. Crown repair with Gelco coating sits at $225-$450, depending on how much crown material we’re cutting back. A full crown rebuild on a badly damaged chase tops out around $890.
What moves the price within those ranges: access to the chase, the flue’s dimensions, and whether we’re matching an existing custom cap or starting from scratch. Multi-flue caps cost more than single-flue. What doesn’t move the price: a salesperson’s commission. You get a written price and written scope before work begins, and that price doesn’t change mid-job. We also offer a free second opinion on any written estimate from another company, and every job carries our 365-Day Done Right Promise. If it’s not done right, we make it right.

FAQs - Chimney Cap & Crown in Flower Mound
Yes, and honestly, your situation is exactly the one we worry about most in Flower Mound. The danger isn’t creosote; it’s water and animals. A 1999 zero-clearance fireplace in our area has a factory cap that’s likely rusted thin or missing, and the mortar wash crown has sat through 25 years of freeze-thaw cycles, including February 2021. We’d rather show you a photo of a sound crown than have you discover a water stain in February. Call (980) 580-8641 and we’ll put a camera on it for a free estimate.
The crown is the concrete or mortar surface at the top of the chase that sheds rain away from the flue opening, while the cap is the metal cover over the flue pipe itself that keeps animals and debris out. On a 1990s prefab unit in Flower Mound, both are usually original and both are usually compromised. We often repair both in the same visit because a new cap on a cracked crown still lets water through. Our photos will show you the condition of each separately.
No, a cracked crown won’t cause creosote buildup, but it will cause other damage. Creosote comes from burning wood, especially low-temperature fires, and has nothing to do with the crown. A cracked crown lets water into the chase and around the firestop, which rusts the metal firebox shell and can eventually stain the drywall or support mold in the chase. On Flower Mound prefab fireplaces that burn eight times a season, crown leaks are the bigger and more common failure. We’ll show you the difference in the camera footage.
Look for hairline cracks running across the crown surface, any spalled areas where the mortar has started to flake, and rust streaks or gaps around the cap base. Also check for missing cap screens or daylight visible between the cap and the flue. In Flower Mound after February 2021, freeze-split crowns were most common on prefab chimneys that had never burned continuously before. If you see moisture dripping down the outside of the chase after a rain, call (980) 580-8641 before the next hard freeze.
We fabricate custom caps in-house for the exact flue dimensions on your prefab fireplace, so you’re not stuck with a universal that leaves gaps. Most Flower Mound zero-clearance units from the 1990s and early 2000s no longer have manufacturer-supported parts, so a custom cap is usually the only correct option. We build them from stainless steel or copper with 5/8-inch mesh, sized precisely to your flue. Each one is priced in writing before we make it.
Get Your Flower Mound Chimney Cap & Crown Inspected the Right Way
If you own a Flower Mound home built between 1990 and 2010, your prefab fireplace cap and crown are at the age where inspection is not optional. The camera-scan standard we use is the same one our founder Corrine Halstead set in 2009, and it’s now written into Clause 4 of the Haven Standard: a documented photo record on every visit. Nothing gets recommended that you can’t see for yourself.
Call (980) 580-8641 today and we’ll schedule a Level 2 inspection with a written price before any work begins. Estimates are free, and the photos are yours to keep.
