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.

Key Biscayne homeowners deal with something most Miamians never think about: salt-laden air that works on chimney masonry year-round, even when the fireplace sits unused from April through November. We know the housing stock here, the seasonal rhythm, and the specific failure patterns that show up in Harbor Drive ranches, Mashta Island homes, and the condo buildings along Crandon Boulevard. When you book a Chimney Inspection with us, you get a technician who already understands what Key Biscayne’s climate does to a chimney before he even rings the bell.
Why Flint Chimney Sweep Is Key Biscayne’s Preferred Chimney Inspection Company
Flint Chimney Sweep operates under the Garrison Standard, the code every Garrison Partners location follows since 2002. That means the price you approve in writing is the price on the invoice. No door-knock adjustments. No “we found something else” add-ons. That matters on Key Biscayne, where some homeowners have told us they were quoted one number over the phone and handed a much larger bill after the tech left.
Every technician who comes to Key Biscayne is background-checked and uniformed. You know who’s walking through your gate. Our phones are answered by a live person 24/7, not a voicemail tree. If you call at 6:00 a.m. before a rental turnover, a human picks up.
The 365-Day Done Right Promise applies to every repair we perform in Key Biscayne. If a covered repair fails within one year, we return at no charge. That’s written on every proposal, not spoken as a vague assurance. Hank Delano, who leads our team, put the process in place so there is never ambiguity about what happens if something goes wrong.
We carry professional-grade materials suited to coastal chimneys: HeatShield for flue repairs, Gelco crown coat for reinforced chimney crowns, and Olympia Chimney caps and dampers. Specified by the job, not by what’s cheapest on the truck.
Chimney Flue Inspection in Key Biscayne
A Chimney Flue Inspection in Key Biscayne is the camera-driven examination of the inner liner that channels smoke and combustion gases safely out of the house, and it costs $225 – $450 depending on access and chimney height. Key Biscayne homeowners need this when there is any visible spalling, a persistent musty smell, a draft problem, or simply years since the last real look at the flue. On an island where the salt air penetrates masonry joints faster than inland Miami, a flue inspection is not a luxury; it is the only way to see what a flashlight from the firebox cannot.
When Salt Air Hits the Flue Liner
Salt particles in the air settle on the chimney crown, then wash down the flue with rain. Over time this corrodes terra-cotta liners and loosens mortar joints. A visual check from the firebox misses hairline cracks that start this way. The camera catches them early, when a parge coat or a HeatShield repair is still an option.
What the Camera Shows
We run a push-camera up the flue and record the entire path on video. You see the photos. We label each defect: spalled liner, cracked tile, separation at the smoke chamber, animal nesting, glazed creosote. Then we tell you plainly what needs attention now and what can wait until the next regular cleaning.
Chimney Fire in Key Biscayne
A Chimney Fire in Key Biscayne is what happens when creosote built up inside the flue ignites, and the associated inspection after one typically runs $275 – $450 because we must document the full internal condition before any further use. Key Biscayne homeowners face this risk even with light seasonal burning because high humidity and irregular use create the exact conditions that trap creosote. A few fires a year, a chimney that never gets hot enough to burn off deposits, and suddenly you have the fuel load that turns a routine burn into a structure fire.
Third-Degree Creosote and What It Means
Third-degree creosote is the hardened, glaze-like coating that forms when creosote repeatedly heats and cools without being removed. A standard brush will not take it off. It requires chemical treatment, rotary chains, or in some cases a full flue inspection to determine whether the liner can even be saved. We document this with the camera so there is no guesswork.
Rental Property Fire Risk
We see this pattern on Key Biscayne more than anywhere else in South Florida: a rental manager books a quick sweep, the guests change weekly, and nobody ever orders an inspection. The smoke chamber clogs, draft reverses, and the first warning is smoke pouring into the living room. If you manage a rental on the island, the inspection is not optional; it is the note that tells you whether the next tenant is safe.
Trusted Brands We Service in Key Biscayne
We install and service chimneys built with HeatShield, Gelco, Olympia Chimney, and Famco components. Because we work these brands regularly, we keep the common replacement parts stocked for Key Biscayne jobs: stainless steel caps, dampers sized for coastal flues, and Gelco crown coat. That means when a Level 2 inspection on a Key Biscayne chimney turns up a rusted damper or a cracked crown, we usually complete the repair on the same visit. No waiting on a parts order. No second scheduling window. The brand name is on the proposal, so you can verify the material quality independently before approving anything.
Common Chimney Inspection Problems We See in Key Biscayne Homes
- Spalled crowns and rusted dampers. The salt air works on concrete and steel continuously, even when the fireplace is idle. We routinely find crowns that have lost their top layer and dampers so corroded they will not close, trapping humid air inside the flue.
- Cracked terra-cotta liners on original chimneys. Many Key Biscayne homes date to the 1960s and 1970s and still have their original clay liners. Temperature swings and salt-based corrosion open hairline cracks that a Level 1 check from the firebox simply cannot see.
- Missing caps and animal entry. Seasonal homes and rentals often go months with nobody looking at the roof. Birds and rodents find an uncapped flue quickly, and by the time a homeowner books an inspection, there is a nest blocking the smoke path.
- Deferred maintenance that looks like active damage. Because many Key Biscayne properties are part-time residences, we often document years of skipped cleanings rather than a single urgent event. The camera shows the difference, and we write the report so you can separate what needs work now from what can wait.
We were called to a 1970s ranch on Harbor Drive after the owner noticed a musty smell in the living room when the fireplace was not in use. Our tech ran a Level 2 inspection with a camera and found a cracked crown, a rusted damper that would not seal, and a first-degree creosote flake in the flue liner. We installed a new stainless steel cap and applied a crown coat, then gave the owner a photo report showing that the creosote was light enough to brush out on the next regular cleaning. No emergency work needed, and a written record of exactly what was done.

FAQs About Chimney Inspection in Key Biscayne
Once a year. Even with light use, Key Biscayne’s salt air and humidity degrade the crown, flashing, and damper on their own schedule. You can burn twice a season and still have a cracked crown letting water into the flue. The inspection catches that before it becomes a masonry repair. Call (830) 251-4560 to schedule, and we will give you a written price before booking.
Cracked terra-cotta liners, separated mortar joints, glazed creosote, and animal nests in the upper flue. A visual check only sees the first few feet. The camera records the entire path, and you get the photos. On Key Biscayne’s older homes, those hidden cracks are the difference between a safe chimney and carbon monoxide seeping into the living space. Call (830) 251-4560 for a camera inspection quote, free of charge.
No. Third-degree creosote is hardened and glazed; a brush will skate over it. Removal requires chemical treatment, rotary chains, or in some cases evaluation for a flue repair before the chimney is safe to use. We will show you the camera footage and the written report so you can see exactly what is there. Call (830) 251-4560 and we will walk you through the options.
We coordinate with your property manager or a designated local contact, complete the inspection, and send you the photo report by email the same day. The written price is approved by you before we start, and the 365-Day Done Right Promise applies regardless of who is on-site. Call (830) 251-4560 to set up the inspection for your Key Biscayne rental.
It needs attention before it becomes a structural problem. A cracked crown lets water into the masonry, and on Key Biscayne that water carries salt. You end up with spalling brick, rusted components, and a bigger repair bill the longer it waits. But not every crack is an emergency. We will tell you if it can wait a season, and show you the photos that prove it. Call (830) 251-4560 for a straight answer and a written quote.
