Why Hearthstone Chimney Co. Is Key Biscayne’s Preferred Chimney Liner & Rebuild Company
We’ve been crossing the causeway into Key Biscayne for more than four decades, long enough to have worked on original post-war CBS homes near Crandon Boulevard and on rebuilt properties that went up after Hurricane Andrew. Our customers here tend to stay put - the median homeowner age skews toward retirement, and many have owned their properties for twenty-five years or more. They remember the contractor who didn’t return calls, and they value a company that documents every inspection with photos they can see and a plain-English verdict they can understand.
Response time to Key Biscayne is typically under two hours from dispatch, traffic across the Rickenbacker permitting. Our technicians carry DuraFlex and Olympia Chimney liner inventory on every truck, so most liner replacements and partial rebuilds finish in a single visit without waiting on mainland parts runs. The 90-Day Done Right Promise applies to every job on the island - in writing, no arguing. If it’s not right, we come back. That’s been our standard since 1984, and it’s not changing.
Our Chimney Liner & Rebuild in Key Biscayne customers know the difference between a company that plans to be here in thirty years and one that might not answer next season. We’re the former.
Our Chimney Liner & Rebuild Services in Key Biscayne
Stainless Steel Liner Installation
Stainless steel liners are the standard for wood-burning and solid-fuel systems in Key Biscayne’s original mid-century homes, many of which still have unlined or terra-cotta flues that cracked during Andrew or have succumbed to decades of salt-air corrosion. A typical stainless steel liner installation in Key Biscayne runs $2,800-$4,200 for a single-flue system, including removal of the old liner, proper sizing with our Level-2 camera inspection, and connection to a new or existing appliance. We use DuraFlex and Olympia Chimney products exclusively - no builder-grade substitutes that won’t survive the island’s environment.
Flexible Liner Solutions
Flexible liners solve the offset and bend problems common in Key Biscayne’s older CBS construction, where chimneys were often built with awkward transitions between floors. These are especially useful in the village center area, where original 1960s ranch homes have been renovated multiple times and the flue path no longer matches the original blueprint. Flexible liner installation typically costs $2,400-$3,800 in Key Biscayne. Our technicians measure with a video scan first, so the liner we pull is the right diameter and length the first time.
Liner Replacement
Replacement becomes necessary when the existing liner has corroded through, separated at the joints, or collapsed from moisture damage - all common conditions here because the island’s chimneys sit unused and unheated, allowing condensation to pool inside the flue year-round. A liner replacement in Key Biscayne generally falls between $2,600-$4,500, with the higher end covering multi-flue systems or difficult access conditions. We also handle Chimney Repair in Key Biscayne when the damage extends beyond the liner itself into the surrounding masonry.
Partial Chimney Rebuild
Partial rebuilds address the crown, top courses of brick, and firebox area without dismantling the entire structure. In Key Biscayne, this is often the right choice for decorative masonry chimneys on 1950s-1970s homes where the crown cracked after a tropical storm and water has been entering for multiple hurricane seasons. Partial rebuilds here typically range $4,500-$7,200. We match existing mortar color and texture where possible, and we always install proper Key Biscayne Chimney Cap & Crown protection and flashing as part of the job - because another storm season is never far off.

Trusted Brands We Service in Key Biscayne
We stock professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield on every truck that serves the island. For Key Biscayne customers, this means no waiting on mainland supply houses and no substitutions with products that can’t handle salt-air exposure. Our relationship with these manufacturers goes back decades, and we specify them because they’ve proven they last in coastal environments. A liner or rebuild done with the right materials, installed correctly, is a job you won’t need to revisit. That’s the point.
Common Chimney Liner & Rebuild Problems We See in Key Biscayne Homes
- Corroded metal dampers and caps from salt-laden air. Every chimney on this barrier island breathes ocean air continuously. Metal components that might last twenty years inland often fail in eight to twelve here, and once the cap is compromised, rainwater and wildlife enter freely.
- Spalled mortar and hairline crown cracks in post-war decorative chimneys. The original CBS homes near Crandon Park and the village center were built with masonry chimneys meant for occasional use, not decades of tropical humidity and salt spray. Mortar joints erode, crowns crack, and water follows gravity straight down the flue.
- Collapsed or separated terra-cotta flue liners from moisture cycling. Because Key Biscayne fireplaces are almost never burned for heat, the flue stays cold and damp year-round. Terra-cotta absorbs this moisture, expands, contracts, and eventually fails - often without any visible exterior sign until a camera inspection reveals the damage.
- Displaced or missing chimney caps after tropical storms. After every named storm season, we find caps blown off or cracked across the island, from oceanfront properties near Bill Baggs Cape Florida State Park to bayfront homes along Harbor Drive. An open flue is an invitation for the heavy rainfall that follows every storm, and for the osprey and monk parakeets that nest throughout the island’s canopy.

Here’s what chimney liner and rebuild work actually costs in the Key Biscayne market, based on jobs we’ve completed across the island:
| Service | Typical Range in Key Biscayne |
|---|---|
| Stainless steel liner installation (single flue) | $2,800 - $4,200 |

What moves a job toward the higher end: multi-flue systems, difficult roof access (common on the island’s older one-story homes with low-pitch roofs), extensive masonry damage requiring scaffolding, and the need for custom-fabricated caps or flashing to match existing architecture. What keeps costs down: catching problems early, before moisture damage spreads from the liner into the surrounding structure.

FAQs - Chimney Liner & Rebuild in Key Biscayne
We typically reach Key Biscayne properties within two hours of dispatch, and same-day service is available for most calls placed before noon. Our technicians cross the Rickenbacker Causeway from our mainland routing point, and we schedule island appointments with buffer time for bridge traffic. Call (844) 803-1545 - a live person answers 24 hours a day, and we’ll give you the next available slot.
Yes, we work across the entire island, from single-family homes near Crandon Park and the village center to high-rise condominiums along the oceanfront and bayfront. Condo chimney work often involves coordination with building management and access to shared mechanical spaces - we’ve handled these logistics many times and understand the approval processes common to Key Biscayne associations.
Yes, we provide emergency response for storm-damaged chimneys across Key Biscayne through our Fireplace Services in Key Biscayne, including displaced caps, cracked crowns, and visible masonry failures. After tropical storms and hurricanes, we prioritize calls from the island because open flues in this environment take on water immediately, and every day of delay increases structural damage. Call (844) 803-1545 any hour - the phone is always answered by a live person, not a recording.
Not significantly - our pricing is consistent across Miami-Dade County, though some Key Biscayne jobs require additional travel time and occasionally barge access for materials on properties with limited driveway space. The bigger cost driver is condition: chimneys here often have more advanced moisture and salt damage because problems go undetected longer. A Level-2 inspection for $289-$389 tells you exactly where you stand.
Every liner installation and rebuild is covered by our 90-Day Done Right Promise - in writing, no arguing. If anything about the job is not right, we return and make it right at no charge. Beyond that, manufacturer warranties on DuraFlex and Olympia Chimney products extend to lifetime limited coverage on many stainless steel liners when properly maintained. We also recommend our Chimney Cleaning & Sweep in Key Biscayne service for annual inspection, even if you don’t burn fires - moisture and wildlife don’t care whether you use the fireplace.
