We’ve been crossing the Rickenbacker Causeway to service Key Biscayne homes for decades. The island’s conditions are unlike anywhere else in Miami-Dade, and that matters when you’re deciding who to let onto your roof. Salt air, hurricane exposure, and a housing stock that spans original mid-century builds to post-Andrew reconstruction all create chimney problems that mainland sweeps often misdiagnose. We know what to look for because we’ve seen it repeatedly, from spalled mortar on Crandon Boulevard estates to moisture-damaged flues in Harbor Island condos where the fireplace hasn’t been lit in fifteen years.
Our Chimney Cleaning & Sweep team arrives with professional-grade equipment, background-checked and uniformed, and we document every finding with photos you can see plus a plain-English verdict. No surprises on the bill. The estimate number matches the invoice number.
Why Hearthstone Chimney Co. Is Key Biscayne’s Preferred Chimney Cleaning & Sweep Company
Forty-two years in this trade means we’ve watched Key Biscayne rebuild after Andrew, after Wilma, after Irma. We’ve swept chimneys on Mashta Point homes where the original 1960s masonry still stands, and we’ve inspected gas inserts in newer towers along Ocean Drive. That continuity matters. A company that plans to be here in thirty more years acts accordingly.
Our reputation on the island is built on showing up when we say we will and leaving the job done right. Key Biscayne homeowners don’t have patience for callbacks, and neither do we. The 90-Day Done Right Promise backs every sweep and inspection in writing, no arguing. If it’s not right, we come back.
Response time to Key Biscayne is typically next-day or within 48 hours, depending on storm season demand. During the weeks following a hurricane, when caps are blown off and flues are exposed to tropical rainfall, we prioritize island calls because we know how quickly moisture damage escalates in this climate.
Live person answers every call, 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. When you smell something musty from your fireplace or notice rust staining on the exterior brick, you reach someone who can dispatch help.
Our Chimney Cleaning & Sweep Services in Key Biscayne
Level 1 Inspection
A Level 1 inspection is the annual standard for Key Biscayne homeowners who use their fireplace occasionally or not at all. We examine readily accessible portions of the chimney exterior, interior, and connecting appliance, checking for salt-corroded dampers, deteriorated mortar, and signs of moisture intrusion that are endemic to island homes. Most Level 1 inspections in Key Biscayne reveal problems the owner never suspected, precisely because the fireplace sits unused and unexamined year after year. A typical Level 1 inspection and sweep in Key Biscayne runs $149-$219.
Level 2 Inspection
Level 2 inspections are required at property transfer, after chimney fire or lightning strike, or when any portion of the system is being replaced. In Key Biscayne, we also recommend them for every home built before 1992 that still retains original masonry, and for any property within two blocks of open water where salt spray accelerates hidden deterioration. Our Level 2 includes a full camera scan of the flue interior, photographs you can see, and a written plain-English verdict documenting every finding. Pricing for Level 2 camera inspections in Key Biscayne is $289-$425, depending on flue accessibility and number of appliances served.
Creosote Removal
True creosote buildup is rare in Key Biscayne, where fireplaces function as decorative features rather than heat sources. When we do encounter glazed creosote, typically in older homes near the Cape Florida Lighthouse area where wood-burning was more common decades ago, we remove it with rotary cleaning systems and professional-grade solvents that won’t damage original flue tiles. The process takes 90 minutes to three hours, and we verify complete removal with camera documentation. Creosote removal in Key Biscayne ranges from $189-$325 when combined with inspection.
Soot Removal and Fireplace Cleaning
Soot removal in Key Biscayne homes more often means clearing accumulated organic debris, mold staining, and the fine sediment left by decades of humid air cycling through an unused flue. We also handle Fireplace Services in Key Biscayne including firebox cleaning, damper restoration, and smoke chamber parging for properties where the system will see actual use. Fireplace cleaning and soot removal typically runs $169-$259.

Trusted Brands We Service in Key Biscayne
We stock professional-grade materials from DuraFlex, HeatShield, and Famco, among others, so repairs identified during your sweep don’t wait on mainland shipping. DuraFlex stainless liners resist salt corrosion far better than standard alternatives, which matters enormously for Key Biscayne’s oceanfront exposure. HeatShield cerfractory flue resurfacing restores eroded clay tiles without full relining, a cost-effective solution we often recommend for original 1960s-1970s construction. When caps or dampers need replacement, Famco components hold up to our warranty standards and the island’s punishing climate. Parts on the truck mean most jobs finish in one visit.
Common Chimney Cleaning & Sweep Problems We See in Key Biscayne Homes
- Corroded metal components from salt-laden air. Every chimney on this barrier island breathes ocean air that pits stainless steel, destroys galvanized caps within five to seven years, and seizes dampers solid. We replace these with marine-grade equivalents rated for coastal exposure.
- Moisture intrusion and biological growth in unused flues. With no cold season to prompt inspection, Key Biscayne chimneys accumulate mold, mildew, and algae inside dark, humid flues. Our sweeps include moisture assessment and documentation of any biological colonization.
- Wildlife nesting, particularly after cap displacement. Osprey and monk parakeets exploit storm-damaged or missing caps, building substantial nests that block airflow and introduce parasites. We remove nesting material humanely and install animal-proof screening.
- Spalled mortar and hairline crown cracks on original construction. Decorative masonry chimneys from the 1950s-1970s, common north of Crandon Boulevard, suffer freeze-thaw damage accelerated by salt penetration. Early detection during routine sweeping prevents costly rebuilds.
Pricing for Chimney Cleaning & Sweep in Key Biscayne, FL
Honest pricing means ranges you can plan around, not bait-and-switch estimates that balloon on arrival.
| Service | Typical Range in Key Biscayne |
|---|---|
| Level 1 Inspection + Sweep | $149 - $219 |
| Level 2 Camera Inspection | $289 - $425 |
| Creosote Removal (with inspection) | $189 - $325 |
| Fireplace Cleaning / Soot Removal | $169 - $259 |
| Annual Maintenance Plan (2 visits) | $279 - $379 |
Several factors move pricing within these ranges: chimney height and roof access difficulty, number of flues served, condition of existing components requiring repair, and whether the system is solid fuel, gas, or decorative. Homes on Mashta Point or Harbor Island with multiple fireplaces and oceanfront exposure typically fall at the higher end. We provide upfront, no-hassle pricing before any work begins. The number on the estimate is the number on the invoice.
Current standing offers include $50 off any repair over $250, a $89 Seasonal Tune-Up, and a permanent 5% Senior and Veteran discount. Free second opinion on any written estimate from another company.
