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 Miramar
A chimney cap or crown replacement in Miramar typically runs $350-$650 for a standard prefab cap installation and $900-$1,800 when a concrete crown needs recoating or rebuilding. Most Miramar jobs are completed in a single visit, and we leave you with a written price before any work starts plus a photo record of the flue before and after. If you’ve got a rusted factory cap, a spalling crown, or an iguana problem in your flue, call (980) 580-8641 and we’ll schedule a camera-scan inspection at your Miramar home.
We know Miramar’s housing stock because we work it every week. The master-planned communities built between 1995 and 2010 dominate this city, and that means prefabricated chimney chases, builder-grade gas fireplaces, and caps that were installed once and never touched again. Our Chimney Cap & Crown team treats these systems for what they are: humidity traps that need inspection even when the fireplace has never been lit.
Why Emberly Chimney Cleaners Is Miramar’s Preferred Chimney Cap & Crown Company
Since 2009, we’ve inspected more than 38,000 chimneys, and every single one has been quoted in writing before work began. That’s not a preference. It’s Clause 1 of the Haven Standard our company operates under. You know the price, the scope, and the warranty before our tech picks up a tool.
For Miramar homeowners, the issue isn’t creosote. It’s rust, moisture, spalling, and wildlife. We see factory caps from the 1990s that have rusted through at the storm collar, letting rain and iguanas into the flue for years. Our techs are background-checked, uniformed, and assigned by name, with a text when they’re on the way to your job in Silver Lakes, Sunset Lakes, or anywhere else in Miramar.
Our crews serve Miramar from our South Florida dispatch office, so scheduling is local and responsive. The 365-Day Done Right Promise applies to every cap and crown job in Miramar: if it’s not done right, we make it right. Clause 4 of the Haven Standard also requires a documented photo record on every visit, so you see exactly what we found and exactly what we fixed.
Our Chimney Cap & Crown Services in Miramar
Cap Installation
A correctly sized cap stops water, birds, and iguanas from entering an uncapped flue. In Miramar’s humidity, a missing or undersized cap means the interior flue liner rusts from the inside out, even if the fireplace has never been lit. We install stainless steel and copper caps sized to the flue’s inside diameter, with a mesh screen rated to keep Broward County’s invasive iguana population out.
Typical cap installation in Miramar runs $380-$650, including the cap, fasteners, sealing at the flue tile, and a photo record of the finished work.
Cap Replacement
Factory caps on Miramar’s 1990s and early 2000s prefab chases were often galvanized rather than stainless. After 15 to 25 years of hurricane-season rain and 80% humidity, those caps rust through at the storm collar and can collapse into the flue during a strong wind event. We replace them with stainless steel or copper from Copperfield and Famco, sized to the chase and sealed so water can’t wick down the outside of the flue pipe.
Replacement in Miramar runs $420-$700 for most prefab chases. Custom chase covers for odd-sized or multi-flue setups run higher, and we’ll walk you through why before quoting.
Crown Repair
A chimney crown is the concrete slab that caps the masonry. On Miramar’s never-used, never-heated fireplaces, the crown stays damp for months at a time. Moisture works into the concrete, efflorescence appears, and spalling begins: the surface flakes away, exposing aggregate and opening cracks. Left alone, water travels down through the crown and into the firebox, rusting the damper and flue liner.
Minor crown repair including crack repair and waterproofing runs $450-$850 in Miramar. Full crown rebuilds start around $1,200 depending on chase size and access.
Crown Coating
Most Miramar crowns need coating, not replacement. We use Gelco crown sealant, applied after the surface is cleaned and all cracks are routed. The coating creates a flexible, waterproof membrane that handles South Florida’s heat and humidity without cracking. Coating a standard prefab crown runs $400-$600 and takes one visit.

BeforeAfterTrusted Brands We Service in Miramar
We stock and install caps, chase covers, and crown coatings from Copperfield, Famco, and Gelco. These aren’t names you need to know, but they matter because they’re what we use instead of off-brand galvanized parts that rust out in five Miramar summers. We also service DuraFlex and HeatShield liner systems when a rusted cap has already caused damage inside the flue. Bringing manufacturer-specific parts means we’re not retrofitting something that doesn’t belong on your chase: we’re replacing it with the right component, and the customer walks away with the maker’s spec sheet plus our photo record.
Common Chimney Cap & Crown Problems We See in Miramar Homes
- Rusted factory caps collapsing into the flue. Wind gusts during hurricane season can snap a corroded cap at the storm collar. What’s left is an open flue, a torn liner, and galvanized debris sitting in the smoke chamber.
- Iguanas nesting and dying inside uncapped flues. Miramar’s invasive iguana population uses uncapped chimneys as shelter. A dead iguana wedged in the damper creates an odor homeowners often blame on mold, and it blocks the flue. A properly fitted cap with mesh stops this.
- Efflorescence and spalling on uncoated crowns. Builder-grade crowns from the 1995-2010 planned-community boom were never meant to sit damp for ten months a year. They spall, crack, and let water into the chase.
- Rusted shut dampers on never-used fireplaces. We see this constantly in Silver Lakes and similar developments. The fireplace has never been lit, but the damper is rusted solid because humid air has been circulating through the uncapped flue since the home was built.

FAQs - Chimney Cap & Crown in Miramar
Because the cap rusts from the outside, not from use. In Miramar’s 75-80% year-round humidity, a galvanized factory cap on a never-used fireplace corrodes at the storm collar within 15 to 20 years. The fireplace being unused doesn’t protect the cap; it means nobody noticed the deterioration. A rusted cap lets rain and humidity into the flue, which then rusts the damper and liner from the inside. We replace the cap with stainless steel, inspect the flue with a camera, and show you the photos. Call (980) 580-8641 for a written estimate.
Iguanas climb stucco walls and enter through uncapped flues or gaps around a rusted cap. Once inside, they nest, and if they die, the body blocks the damper and sends decay odor through the firebox. A properly fitted cap with a stainless steel mesh screen sized to the flue keeps them out. We’ve pulled enough dead iguanas from Miramar flues to treat wildlife inspection as a standard part of every visit. Call (980) 580-8641 and we’ll check the entire chase while we’re there.
Yes, in most cases. If the crown is spalling but the chase structure is intact, we route the cracks, clean the surface, and apply a Gelco crown coating. That stops water intrusion without a full rebuild, which runs far less than tearing out the chase. The catch is that deep structural cracks or a shifted flue tile require more than a coating, and we won’t coat over damage that needs repair. We’ll show you the camera footage and the written price first. Call (980) 580-8641.
My guess, based on what we see weekly, is a dead iguana in the flue or firebox. Or a rusted-through damper plate that’s holding a carcass. We camera-scan the flue, identify the blockage, remove it, and replace the rusted damper. If the cap is missing or rusted, we install a replacement cap with mesh the same day. The smell isn’t mold, and painting over it won’t help. The fix is mechanical, and we’ll photograph everything. Call (980) 580-8641 for a written estimate.
Yes, if both flues terminate at the same chase top and one is open. A multi-flue cap covers both flues with a single, properly sized lid, sealing the unused flue against humidity and wildlife while still venting the gas fireplace correctly. In 1995-2010 Miramar homes, builder-installed prefab chases often have a second flue that was never used and never capped. A multi-flue cap is usually the right fix. We’ll confirm with a camera inspection and give you a written price before work. Call (980) 580-8641.
One Local Insight We Don’t See Anywhere Else
In Miramar’s 1995-2010 master-planned communities like Silver Lakes, builder-installed prefabricated chimneys were almost never capped or used. So the flue system corrodes internally from 75-80% year-round humidity rather than creosote buildup. That means a rusted or missing cap here is usually the first sign of a much bigger problem inside the chase: iguana nesting, efflorescence on the firebox, third-degree rust flakes coating the smoke chamber, or a damper fused shut. This is the default condition in Miramar, not the exception. And it’s why we treat an idle fireplace as a moisture management problem, not a maintenance afterthought.
In a Silver Lakes two-story CBS home, our tech pulled a copper-mesh cap from a builder-grade prefab flue that had rusted through at the storm collar. Inside, we found a dead iguana wedged in the firebox damper and third-degree rust flakes coating the smoke chamber. We installed a Famco multi-flue cap sized to the chase, replaced the rusted damper plate, and coated the prefab crown with Gelco to stop spalling before the next hurricane-season downpour. That’s what a Miramar chimney cap job actually looks like: not a cosmetic upgrade, but stopping a slow-motion failure that’s been running since the home was built.
