Fast, Reliable Chimney Liner & Rebuild Across Longwood
Chimney liner installation and chimney rebuilds in Longwood typically run $2,800-$7,500 depending on whether we’re lining an existing flue or rebuilding from the crown down. Most jobs are completed in a single visit, and our Chimney Liner & Rebuild team carries DuraFlex stainless steel liners and HeatShield resurfacing materials on every truck. We’ve been driving to Longwood since 2014 - from the historic district near West Church Avenue out to the Wekiva Springs corridor in 32779 - and we know the difference between a 1980s Heatilator zero-clearance system and a late-1800s brick flue before we step through your door. Call (877) 565-7563; a live person answers, day or night.
Why Hearthstone Chimney Co. of Miami Is Longwood’s Preferred Chimney Liner & Rebuild Company
We’ve worked on chimneys along Markham Woods Road, in the subdivisions near Longwood Hills, and throughout the Wekiva Springs corridor for more than four decades. That longevity matters in a town where many homes were built during Seminole County’s suburban boom, because the problems we find in a 1978 tract home are nothing like those in a 1992 custom build - and both differ completely from the historic masonry near downtown.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your clay liner is spalling or your mortar crown has crumbled, we show you exactly where and explain why it happened. Roy Dempsey built this company on the principle that a homeowner should understand the repair before signing anything.
Calls are answered by a live person 24 hours a day, 7 days a week - not a callback queue, not an app. Our background-checked, uniformed technicians arrive when we say they will, and most liner and rebuild jobs in Longwood are completed in a single visit. The number on your estimate is the number on your invoice. Our 90-Day Done Right Promise is in writing, with no arguing: if it’s not right, we come back.
Our Chimney Liner & Rebuild Services in Longwood
Full Chimney Rebuild
In Longwood’s 1970s-1990s housing stock, full rebuilds are more common than many homeowners expect. The combination of intense subtropical UV, violent summer thunderstorms, and chimneys that sit unused for 11 months allows moisture to silently destroy mortar crowns, degrade prefab metal components, and rust firebox seams. On a custom home in the Wekiva Springs corridor, we rebuilt a crumbling mortar crown and installed a new DuraFlex stainless steel liner inside a 1980s Heatilator zero-clearance fireplace. The homeowner had never used the fireplace in five years, but summer thunderstorms had poured water down the flue, causing the original clay liner to spall and the metal firebox to rust at the seams. A full rebuild addressed the crown, the flue, and the damaged firebox - done right, and we stand behind it.
Stainless Steel Liner Installation
We install DuraFlex and Olympia Chimney stainless steel liners throughout Longwood’s 32750, 32752, 32779, and 32791 ZIP codes. These liners are rated for wood, gas, and oil appliances and carry a lifetime warranty when properly installed. In Longwood’s climate, stainless steel is the only material we recommend - aluminum corrodes too quickly under the combination of humidity, occasional use, and acidic condensation that builds in under-fired flues. Our technicians measure on-site and fabricate custom transitions for zero-clearance systems that lack factory-compatible parts.
Liner Repair and Resurfacing
Not every damaged liner needs full replacement. For clay flues with minor spalling or cracked joints, we apply HeatShield cerfractory resurfacing - a specialized mortar that restores the flue’s integrity without removing the original structure. This is often the right approach for historic masonry homes near downtown Longwood, where preserving original construction matters. We document the before-and-after with camera inspection photos, and we only recommend resurfacing when the damage is genuinely repairable. If the flue is too far gone, we’ll tell you plainly and explain why.
Partial Rebuild and Crown Repair
Many Longwood homes need crown repair or partial rebuilding before any liner work can begin. A cracked or missing crown allows June-through-September thunderstorms to pour directly into the flue, destroying liners from the top down. We pour new concrete crowns with proper drip edges and expansion joints, or we install pre-formed Famco crown forms when the chimney configuration allows. Without this step, even the finest stainless steel liner will fail prematurely.

Trusted Brands We Service in Longwood
We stock DuraFlex flexible liners, HeatShield resurfacing materials, and Famco crown and cap components on every truck serving Longwood. For custom fabrication on older zero-clearance systems, we source from Olympia Chimney and Copperfield supply houses with next-day delivery to our Miami warehouse. This means most Longwood homeowners aren’t waiting weeks for parts - we measure, fabricate if needed, and complete the job. No builder-grade substitutes. The materials we use are the same ones specified by factory engineers, installed by technicians who understand how each component interacts with your specific chimney system.
Common Chimney Liner & Rebuild Problems We See in Longwood Homes
- Moisture destruction from summer thunderstorms. Seminole County’s June-through-September storm season drives heavy rain into uncapped or crown-damaged flues. Because Longwood fireplaces may sit unused for 11 months, homeowners rarely notice the damage until a liner collapses or the firebox rusts through. We inspect for water trails, efflorescence, and spalled clay every time.
- Chimney swift nesting delays repairs. These federally protected birds occupy Longwood chimneys from roughly March through October. If we find active nesting during inspection, we cannot legally cap or line the flue until the birds depart. We schedule return visits accordingly - something our technicians in colder markets almost never encounter.
- Obsolete zero-clearance systems with no compatible parts. Longwood’s 30-50-year-old Heatilator, Superior, and similar factory-built fireplaces often lack available replacement components. We fabricate custom transitions or recommend full unit replacement when the original manufacturer has discontinued support.
- Collapsed mortar crowns on masonry chimneys. The historic district near downtown Longwood contains late-19th-century brick flue systems with original crowns that have simply aged past their service life. These require entirely different inspection and repair approaches than prefab systems - we never apply a one-size-fits-all method.

FAQs - Chimney Liner & Rebuild in Longwood
The near-zero burn frequency in Longwood’s 1970s-1990s homes means moisture intrusion and wildlife damage - not creosote - drive most failures. Summer thunderstorms destroy mortar crowns and rust prefab fireboxes long before the liner itself wears out. A liner replacement alone won’t stop water from pouring through a cracked crown. We inspect the entire system and recommend rebuilds only when the structure demands it. Call (877) 565-7563 for a free inspection with photos you can see.
No - and we say this as craftsmen who have repaired DIY attempts that created dangerous conditions. Stainless steel liner installation requires proper sizing for your appliance, correct insulation to prevent creosote condensation in under-fired flues, and NFPA 211-compliant connections that most homeowners cannot verify. In Longwood’s humidity, an improperly sealed liner corrodes faster than no liner at all. Our background-checked technicians complete most installations in a single visit with the 90-Day Done Right Promise in writing. The cost of fixing a DIY mistake always exceeds professional installation.
We cannot legally disturb active chimney swift nests from roughly March through October - these birds are federally protected under the Migratory Bird Treaty Act. If our Level-2 camera inspection reveals nesting, we document the finding, explain the timeline, and schedule your liner repair for after the birds have naturally departed. We then install a proper cap to prevent reoccupation. This is a routine part of our work in Longwood, and we handle the scheduling so you don’t have to think about it again.
Infrequent use often causes more damage than regular burning. In Longwood’s subtropical climate, an unused flue accumulates acidic condensation that attacks metal components, while summer thunderstorms introduce moisture that spalls clay and rusts fireboxes. We camera-inspect every system before recommending replacement - sometimes resurfacing or partial repair is sufficient. But a 1990s prefab unit that has never been inspected is frequently past its rated service life. We’ll show you exactly what we find and explain your options with no pressure. Call (877) 565-7563 for a free second opinion on any written estimate.
Aluminum corrodes rapidly in Central Florida’s humidity, especially in under-fired flues where acidic condensation forms. Stainless steel - specifically the 316Ti alloy used in DuraFlex and Olympia Chimney products - resists both moisture and acid attack for decades. The lifetime warranty on professional-grade stainless liners is only valid with proper installation, which is why we measure, fabricate, and document every job. In Longwood’s climate, aluminum is a false economy. We don’t install it, and we don’t recommend it.
