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.

Why Flint Chimney Sweep Is Key Biscayne’s Preferred Chimney Sweep Company
Key Biscayne homeowners call us after getting burned by chimney companies that no-show, bump the price at the door, or leave soot on the baseboards. We are part of the Garrison Partners family, founded in 2002, and every Key Biscayne job is run under the same code: background-checked, uniformed technicians, a written price before work starts, and a 365-Day Done Right Promise on any repair. If a covered repair fails within one full year, we return at no charge. No argument, no re-inspection fee.
Our technicians know the difference between a chimney in the Cape Florida area and one off Crandon Boulevard. Salt air and hurricane-driven rain eat chimney caps and flashing faster here than almost anywhere else in South Florida. That local knowledge matters when we inspect the crown, the cap, and the flue liner. We do not treat every chimney the same. Readers looking for a broader look at what we do can start with our Chimney Sweep overview. For this specific island, see what applies directly to Chimney Sweep in Key Biscayne.
Dispatch for Key Biscayne is coordinated from our Miami (South FL) office, so scheduling is straight, and crews arrive in uniform with the truck stocked for masonry fireplaces, inserts, and prefab units alike. We carry parts for Famco, Copperfield, DuraFlex, and HeatShield systems so we are not ordering a damper assembly after the fact and making you wait a second week.
Chimney Sweep Services in Key Biscayne
Chimney Sweep Services in Key Biscayne begin with a straight answer on what you actually need. A standard sweep removes soot and creosote from the flue liner and smoke chamber, cleans the firebox, and checks the damper. A Level 1 inspection accompanies every sweep and covers the accessible portions of the chimney, the cap, the crown, and the basic condition of the masonry. A Level 2 inspection is called for when something in the Level 1 findings is off, when the home is changing hands, or after a storm that may have damaged the structure. In Key Biscayne, with salt exposure year-round, it is not rare for a Level 1 to uncover cap or flashing issues that deserve a closer look.
Level 1 and Level 2 Inspection
A Level 1 inspection is part of our standard sweep, not an upcharge. A Level 2 inspection in Key Biscayne runs $299 to $449 depending on the chimney’s height and access, and it is always backed by camera footage. You see exactly what we see. No vague claims about a liner that “might” be cracked.
Creosote and Soot Removal
Creosote removal in Key Biscayne homes is straightforward for first-degree deposits but gets harder fast once glaze forms. That is why the cadence matters. A fireplace used a few times a month during winter should be swept yearly. The cost sits inside the same $189 to $289 range as long as the buildup is not heavy glazing.

Chimney Cleaning in Key Biscayne
Chimney Cleaning in Key Biscayne is not just about the flue. A complete job includes the smoke chamber, damper, firebox, and ash dump, plus the cap and crown as seen from the roof. In a salt-air climate, exterior components often fail inspection long before the flue interior does. Our standard cleaning includes a camera inspection and a written photo report so you can see what was actually cleaned and what, if anything, needs attention later.
Annual Sweep and Fireplace Cleaning
An annual sweep in Key Biscayne runs $189 to $289 and should be scheduled before the winter burning season. Fireplace cleaning, when the firebox has heavy ash, mineral staining, or smoke damage, adds $75 to $125 depending on size and condition. Both services come with the same written price before work starts.
Damper and Draft Check
A smoky fire in Key Biscayne is often not the flue at all. In the Cape Florida area we swept a masonry fireplace where the homeowner had skipped three seasons and complained of a smoky draft on cool nights. The tech found a partially closed damper, a cracked chimney cap from salt and storm exposure, and first-degree creosote coating the flue. We brushed the flue, freed and tested the damper, applied a HeatShield repair at a hairline flue-liner joint, and the draft improved immediately. A photo report went out the same week with the crown and cap flagged for follow-up.
Trusted Brands We Service in Key Biscayne
Key Biscayne homes run a mix of masonry flues, stainless steel liners, and factory-built fireplaces. We work with professional-grade materials because the brand matters when you are dealing with heat, salt, and moisture. DuraFlex and HeatShield products for liner repair and resurfacing, Famco for caps and dampers, Copperfield for chimney components. We stock local parts for Key Biscayne customers so a cracked cap or a stuck damper is often a one-trip fix rather than a two-week wait. No mystery material, no generic part that will fail in the salt air inside two seasons.
Common Chimney Sweep Problems We See in Key Biscayne Homes
- Salt-corroded caps and flashing. Key Biscayne’s oceanfront air eats galvanized steel quickly. A cap that looked fine last season can be rusted through by the next inspection, and flashing that leaks lets rain into the smoke chamber where it mixes with creosote into a corrosive sludge.
- First-degree creosote ignored until it becomes glaze. Most Key Biscayne fireplaces sit dormant nine months a year, so when they do burn, they burn humid, low-temperature fires that deposit soft creosote. A yearly sweep removes it. Skip two or three years and it hardens into a glaze that can require chemical treatment or mechanical removal, which raises the price above the standard range.
- Hairline crown cracks from hurricane-season driven rain. Masonry crowns on Key Biscayne take direct storm hits from the east. Small cracks widen as salt water evaporates and recrystallizes inside the mortar. A $75 crown seal now prevents a $1,500 smoke chamber repair later.
- Dampers stuck from rust and salt buildup. We see this on nearly every second or third chimney in Key Biscayne. The fix is often simple: clean the hinge, lubricate the pivot, test the cable. Sometimes it requires a new damper assembly. We will tell you which one you actually need, with the price before we start.

FAQs About Chimney Sweep in Key Biscayne
Once a year, even with light use, because Key Biscayne’s humidity and salt air encourage creosote to absorb moisture and harden. A chimney that burned ten fires last winter still has first-degree creosote, and that is best caught before it cures into glaze. If you use the fireplace only a handful of times each year and had a clean inspection last season, you can safely stretch to 18 months, but not beyond two years. Call (830) 251-4560 and we will give you a straight cadence recommendation for your specific fireplace.
Yes. Key Biscayne’s oceanfront salt air and hurricane-season wind-driven rain corrode galvanized caps and flashing significantly faster than inland Miami. Where an inland cap might last eight to twelve years, we routinely replace caps on Key Biscayne homes at the five-to-seven-year mark. Masonry crowns also show hairline cracks earlier here because salt water cycles through the mortar. Our inspections always include the roof-level view, which inland crews sometimes skip.
Always. Every sweep we perform in Key Biscayne includes a camera inspection of the flue interior, and you get the photo report in writing. We do this because most serious chimney problems are invisible from the firebox and from the roof. The camera finds hairline liner cracks, hidden creosote glaze, and deteriorated mortar joints. If we recommend a repair, you will see the footage that justifies it before you spend a dollar.
You get a written price before we arrive for the sweep itself, based on the chimney type and size you describe. If the inspection finds something extra, like a corroded cap or a liner joint that needs a HeatShield repair, we hand you a written quote before any repair work starts. The number on the invoice is the number you approved, and any repair is covered by the 365-Day Done Right Promise. If it fails within one year, we come back at no charge.
In most cases we can schedule you within a few days, not the same day. A sweep is a booked appointment, and the real urgency in Key Biscayne is seasonal: you want the chimney clean and inspected before the first cool nights of the burning season. If you have a serious concern like a visible roof leak at the chimney or a strong creosote smell, call (830) 251-4560 and we will tell you honestly how soon it needs attention.
