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 Repair Across Aventura
Most chimney repair in Aventura runs between $275 and $2,200 depending on the failure, with cap installation and crown work on the lower end and flue relining or partial rebuilding on the higher end. We work on the low-chase, tile-roof chimneys that dominate this city’s housing stock, and we put every price in writing before a single tool comes off the truck. If you’re off Biscayne Boulevard or Country Club Drive and the first fire of the season pushed smoke back into your living room, call (830) 251-4560. A real person answers, and we’ll walk through what you’re seeing before we ever schedule a visit.
Why Flint Chimney Sweep Is Aventura’s Preferred Chimney Repair Company
Aventura homeowners call us because the written guarantee actually says what will happen: if a repair covered under our 365-Day Done Right Promise fails within one full year, we return and fix it at no charge. No phone tag, no requote, no argument. Our technicians are background-checked and uniformed, and they arrive inside the window we give you, not somewhere in a four-hour fog. Hank Delano runs our operation under The Garrison Standard, the same code every Garrison Partners location follows. That means the price on the estimate is the price on the invoice. Full stop.
We also know what salt air does to chimney hardware here. A galvanized cap on a house near the Intracoastal lasts three or four seasons before the legs rust through. We spec materials for this climate, not for a warehouse shelf in Ohio. When we quote a cap or crown repair in Aventura, we’re quoting the fix that holds up to wind-driven rain off the water and UV that chews through cheap sealants in two summers. We’ve been part of the Garrison Partners family since 2002, and the process hasn’t changed: document the failure, price it in writing, do the work, stand behind it.
Chimney Cap Installation in Aventura
Chimney Cap Installation in Aventura typically runs $340 to $620 for a professional-grade stainless or copper cap sized to the flue and secured with proper mechanical fasteners, not caulk. The cap is the first line of defense on any chimney, and on Aventura’s low-chase, tile-roof homes, it’s often the only thing standing between a tropical downpour and the inside of your smoke chamber. Without one, rain pours straight down the flue, rusts the damper shut, and soaks into the masonry from the inside. Add raccoons and iguanas looking for a dry den during the wet season, and an uncapped flue becomes a wildlife entry point fast.
What a proper cap install looks like
We measure the flue, not the outside of the chase. A cap that’s sized to the wrong dimension rattles in the wind or chokes the draft, and both cause calls the first cold front in November. We install Gelco and Copperfield caps with stainless hardware and a mesh spark arrestor sized so it doesn’t clog with creosote after one season of burning. Every install includes a photo of the finished cap from the roof, so you can see the work without climbing a ladder.
Why Aventura homes need caps in pairs
Homes off West Country Club Drive and around the Turnberry area often have a second flue for a water heater or gas furnace. That flue needs a cap too, usually a smaller one with a different mesh gauge. We quote both in the same line item so there’s no surprise second trip charge. If you’re unsure whether every flue is capped, a camera inspection during the estimate answers it in ten minutes.
Chimney Cap Replacement in Aventura
Chimney Cap Replacement in Aventura runs $295 to $540 when the old cap is simply corroded out and the mounting surface is sound. The telltale sign is a cap you can see pulling away from the crown, or one that’s lost half its mesh to rust after a few summers of Intracoastal salt air. Cheap galvanized caps fail wholesale here, and once the legs snap, the cap ends up sliding down the tile roof in the next squall. That’s a $95 emergency roof repair waiting to happen on top of the cap replacement itself.
Signs the cap is gone before you see it
You’ll usually hear it first. A loose cap clanks against the chase cover when the afternoon sea breeze kicks up, and if you’re in a condo building off Aventura Boulevard with a shared vent, that noise carries through the fire wall. You may also find small piles of rust granules in the firebox or on the smoke shelf during a sweep. By the time a cap fails visibly, water has usually been getting into the flue for a season or more.
What we replace it with
We don’t carry galvanized caps on the truck. For Aventura, we spec Copperfield stainless or solid copper caps with welded mesh and stainless legs. Copper holds up to salt air better than any coated steel and doesn’t need paint. If the old cap was screwed into a spalled crown, we rebuild the crown first, then mount the new cap on solid masonry. A cap screwed into crumbling concrete is a cap that leaks within the year.
Trusted Brands We Service in Aventura
We work with the chimney trade’s core product lines because our guarantee depends on parts that don’t fail at the warranty’s edge. That means DuraFlex for relining work, HeatShield for flue resurfacing where a full liner isn’t needed, and Gelco, Copperfield, and Famco for caps, dampers, and flashing. For Aventura customers, we keep common cap sizes and flashing profiles stocked locally so a straightforward replacement doesn’t wait on a freight truck from the Midwest. When a chimney near the Turnberry golf course needs a cap, our team arrives with the part on the truck, not a quote for a second visit.
Common Chimney Repair Problems We See in Aventura Homes
- Flat crown puddling and spalling. Aventura’s low-slope chimney crowns collect water after the afternoon squalls that blow through from June through September. The concrete saturates, the aggregate pops, and the crown starts shedding chunks onto the tile roof. Once the crown spalls past the flue collar, water seeps down the outside of the liner and rusts it from the back side, a failure you rarely see on tall masonry stacks.
- Salt-air cap and flashing corrosion. Homes east of Biscayne Boulevard sit close enough to the Intracoastal that salt mist settles on metal every night. Galvanized caps and step flashing corrode through in a few seasons, and once the flashing lifts, water rides straight into the chase. We replace with stainless or copper and seal with a polyurethane caulk rated for coastal exposure, not the acrylic tube from the hardware store.
- Rusted dampers and smoke chambers. When a chase cover is undercut or missing and wind-driven rain gets past it, the damper is the first thing to seize. A rusted-open damper lets conditioned air pour out of the living room all summer. A rusted-shut damper kills the draft and smokes out the house on the first fire. We replace dampers with top-sealing models that close tight and open with a cable, not a struggle.
- Wind-driven rain through uncapped or undercap flues. The low chases on Aventura’s tile-roofed homes don’t create the stack effect that keeps taller chimneys dry. Rain hits the cap sideways and gets driven under the lid, especially during tropical storm bands. The fix is a cap with a taller profile and a proper rainscreen, plus a crown re-sloped so water sheds toward the drip edge instead of pooling in the middle.
Pricing for Chimney Repair in Aventura, FL
A crown repair or recoat on a single-flue Aventura chimney runs $450 to $900.

On a tile-roofed house off Country Club Drive near the Turnberry golf course, our tech opened the firebox and found the damper rusted shut and the smoke chamber shedding flue tiles after years of tropical downpours pushing water past a cracked chimney crown. We swept the flue, ran a camera past a washed-out mortar joint, rebuilt the crown, and set a Gelco stainless cap with a proper spark arrestor, then handed the homeowner a photo report showing each repaired joint. The fireplace drafted correctly on the first test burn, and the damper now opens with two fingers instead of a pry bar.
Aventura is a fully built-out, high-rise-dominated city where nearly every chimney is a low, decorative chase on a tile-roofed single-story house rather than a tall masonry stack, so wind-driven rain and salt air, not fire volume, drive most of the deterioration we repair. Because the city sits between the Intracoastal and Biscayne Boulevard, caps and crowns here take far more UV and salt exposure than chimneys a few miles inland in Miami Gardens. What that means for you: the standard national advice about chimney maintenance doesn’t always translate, and the fix that works in a dry climate with tall stacks is often the wrong fix on a low chase in 33180 or 33160. We price and spec for the chimney you actually have.

FAQs About Chimney Repair in Aventura
Annual cleaning is enough for most Aventura fireplaces that burn seasoned wood a few nights a week during the short South Florida cool season, but the chimney’s hardware often needs attention on a different clock. Caps, crowns, and flashing fail faster here due to salt air and storm-driven rain, so a camera inspection every two years catches deterioration before it becomes a leak. If you burn green wood or the fireplace sits unused for years, schedule a sweep and inspection before lighting it again. Call (830) 251-4560 and we’ll give you a straight answer and a written price.
No. We book a scheduled window and we hold it, because a proper repair on a tile-roof chase means staging materials, inspecting the full flue with a camera, and doing the work without cutting corners. What we do promise is a written price before any work begins and a one-year written guarantee on every repair. If you have water actively pouring into the firebox during a storm, call (830) 251-4560 and we’ll prioritize you for the earliest available slot.
A flashlight shows you the firebox and maybe the first few feet of flue; a camera sees the entire liner to the top, including hairline cracks, washed-out mortar joints, warped tiles, and rust pockets behind the damper. On Aventura chases, it finds water tracks inside the flue that indicate a failing crown or cap long before stains show on the ceiling. We include the camera run in our repair estimate and you get the photo report to keep, so you can see every joint we’re recommending we fix.
Yes, stage one and stage two creosote can be removed with rotary brushes and hand sweeping, which is what a standard chimney sweep involves. Stage three glazed creosote is a different material, hard and tar-like, and brushing alone won’t remove it. That’s where flue resurfacing with HeatShield or a full liner replacement comes in. We’ll tell you plainly which stage you’re dealing with and show you the camera stills. If it’s brush-out work, you’ll know the price before we start.
Minor spalling on the crown’s drip edge, a cap with light surface rust, and hairline mortar cracks can usually wait one season without risk, as long as you’re not burning and no water is entering the flue. But once the damper is rusted open, the cap legs are broken, or you can see daylight through a crack in the crown, the failure is actively letting water into the house, and that’s when rust and mold start. If you’re not sure which category you’re in, call (830) 251-4560 for a camera inspection and a straight recommendation. If it can wait, we’ll say so and put that in writing.
