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 Sweep Across Key Biscayne
A standard chimney sweep in Key Biscayne runs $185 – $325, and a Level 1 inspection typically costs $149 – $229. That’s before any repairs, which on this island usually means replacing corroded caps or flashing rather than removing creosote. We’re Alcott Chimney Sweep, and we’ve been handling coastal chimney failures since 2002. Ruben Castellano leads our team, and every technician we send to Key Biscayne arrives with a name and photo sent to you in advance, plus a photo ID badge at your door. Call (336) 863-3889 for an exact quote.
The salt air here doesn’t wait. A chimney that looked fine last season can have a rusted-through cap and a crumbling crown by the time hurricane season ends. We schedule sweeps and inspections across Key Biscayne within a few days, and our Chimney Sweep crew works around your schedule, not ours.
Why Alcott Chimney Sweep Is Key Biscayne’s Preferred Chimney Sweep Company
Key Biscayne homeowners face a problem most chimney companies in Florida don’t understand: the damage starts outside, not inside. We do. Our technicians know that a fireplace lit twice a year in a bayfront home off Harbor Drive can still have a flue that’s unsafe because the cap rusted through and let wind-driven rain pour into the smoke chamber.
We’ve worked on homes from the single-family streets near Crandon Park to condos along Ocean Drive that actually have vented fireplaces. Homeowners here want to know who’s coming before they open the door. That’s the Threshold Standard: every technician is background-checked, identity-verified, uniformed, and sent to you by name and photo before arrival. No exceptions, no “the guy in the truck.” You’ll know exactly who’s walking up your driveway.
Every job gets a written price before any work starts. Every repair gets a written guarantee. If a repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s not an add-on.
Chimney Sweep Certified in Key Biscayne
Chimney Sweep Certified in Key Biscayne means something different than it does 20 miles inland. Here, the sweep itself is usually a secondary concern. What matters is that the technician opening your flue knows what salt air has already done to the metal components above the roofline. We sweep to clear debris, bird nests, and whatever soot has accumulated, but we’re also looking at corrosion on the cap, damper, flashing, and crown while we work.
On Key Biscayne, a standard sweep takes 45 – 90 minutes and runs $185 – $325. If you haven’t had the chimney inspected in two years or more, we recommend pairing the sweep with a Level 1 inspection ($149 – $229) so we can document the condition of everything from the firebox to the chimney cap.
What a Sweep Actually Does Here
We run brushes from the flue opening down through the smoke chamber and into the firebox, removing soot, light creosote, and whatever the island’s birds and wind have deposited. For gas-log fireplaces, we clean the logs, burner, and pilot assembly. Then we check the damper movement and look for water staining, which on Key Biscayne is the single most reliable sign that a cap or crown has failed.
Annual Sweep Without the Upsell
We don’t recommend work you can’t see. If we find rust-through or spalling, you’ll see it too, because we show you photos from the roof before we quote a repair. If your chimney is clean and the components are holding, we’ll tell you that and schedule your next sweep for next year.
Gas Fireplace Cleaning in Key Biscayne
Gas Fireplace Cleaning in Key Biscayne is the service we perform most often, because the island’s housing stock is full of gas-log fireplaces that exist for ambiance, not heat. A standard gas fireplace cleaning runs $175 – $300. That includes removing and cleaning the logs, cleaning the burner and pilot, clearing the venting, and checking the damper and glass seal.
If the fireplace has a musty smell or the damper sticks, that’s usually moisture getting in through a corroded cap or cracked crown. Cleaning the unit won’t fix the source of the water. We’ll show you where the moisture is entering and quote that repair separately, with a written price before anything is touched.
Corrosion-First Inspection for Gas Logs
Even if you’ve never burned the gas logs, the metal parts inside the firebox and up in the flue are sitting in humid, salty air year-round. We check the burner ports for corrosion, the pilot assembly for rust, and the venting for blockages. A gas fireplace that won’t light on the first try often has corroded connections rather than a gas supply issue.
What Gets Replaced Most
Chimney caps are the most common replacement on Key Biscayne gas fireplaces. The builder-grade galvanized caps rust through in a few seasons of direct salt exposure. We install Miami-Dade NOA-approved stainless caps, typically from Copperfield, and we stock the common sizes locally so there’s no week-long wait for parts.
Trusted Brands We Service in Key Biscayne
We work with professional trade brands that are engineered for coastal conditions, including Copperfield caps and dampers, DuraFlex liner systems, and Famco components. We keep common sizes of these parts in local stock so a Key Biscayne repair isn’t delayed while something ships from a warehouse. If your existing setup uses another brand, we service that too, but when we replace a corroded component, we specify materials rated for what this island’s salt air throws at them.
Common Chimney Sweep Problems We See in Key Biscayne Homes
- Galvanized caps rusted through at the seams. Builder-grade caps fail fast near the bay. Once the seams open, wind-driven rain pours directly into the flue, staining the firebox and feeding mold growth. The fix is a stainless cap, and it needs to be Miami-Dade NOA-approved.
- Crumbling chimney crowns and spalling mortar joints. Humidity over 75% most of the year, combined with salt spray, breaks down standard mortar. A crown that no longer sheds water lets moisture soak into the chimney structure, and that’s a repair that gets worse every season it’s ignored.
- Debris and bird nests in rarely used flues. Because these fireplaces are lit so seldom, there’s no creosote smell to warn you something’s blocking the flue. The first light-up of the season smokes the living room, and that’s when we get the call. A Level 2 inspection catches this before you strike a match.
- Sticking dampers and musty firebox smells. Salt air corrodes damper hinges and tracks. If the damper won’t fully open or close, or the firebox smells like a boat bilge, moisture is getting in somewhere above the roofline. We trace it to the cap, crown, or flashing and show you photos before quoting the fix.

FAQs About Chimney Sweep in Key Biscayne
Do I really need an annual chimney inspection on Key Biscayne if we never burn a fire?
Yes, because salt air corrodes the metal components above the roofline whether you use the fireplace or not. A chimney that’s never lit still has a cap, crown, flashing, and damper exposed to ocean spray every day. Annual inspections catch a rusted cap or spalling crown before it lets water into your firebox and walls. Call (336) 863-3889 to book an inspection.
What kind of chimney cap should be installed on a Key Biscayne home instead of the builder-grade one?
A stainless steel cap with a Miami-Dade NOA approval rating is the only sensible choice on a barrier island. Galvanized caps rust through in a few seasons of direct salt exposure. We install Copperfield stainless caps because they’re engineered for coastal wind loads and corrosion resistance. If your current cap is galvanized and more than three or four years old, it’s worth having us take a look.
How often should a Key Biscayne chimney be inspected given the salt air?
Annually, at minimum. If your home is directly on Biscayne Bay or the Atlantic side, or if you’re within a few hundred feet of open water, twice a year isn’t excessive. The salt load is highest where wind carries spray off the bay, and that’s most of Key Biscayne. We’ll tell you what we find and whether you can safely go longer between inspections.
Our gas-log fireplace smells musty and the damper sticks – what’s usually wrong?
That combination almost always means moisture is entering through a failed cap or cracked crown. On Key Biscayne, this is the most common call we get. The musty smell is mildew in the firebox or smoke chamber, and the damper is binding because its hinges or tracks are corroding. We’ll trace the water entry point, show you photos, and quote the cap or crown repair separately from the cleaning.
Can you clean and service a gas fireplace on Key Biscayne, or is that a different trade?
We handle gas fireplace cleaning and service. That includes the logs, burner, pilot assembly, venting, damper, and glass seal. The only thing we don’t do is gas line repair or installation, which requires a licensed plumber or gas fitter. For everything else, call (336) 863-3889 and we’ll take care of it.
