Fast, Reliable Chimney Liner & Rebuild Across Middleburg
Chimney liner and rebuild work in Middleburg typically runs $1,800-$6,500 depending on whether we’re installing a stainless steel liner in an existing masonry chase or rebuilding from the roofline up. Most jobs in the 32068 and 32050 ZIP codes are completed in a single day, and our technicians carry the common liner diameters and crown materials needed for Middleburg’s ranch-style housing stock on every truck.
We’ve been driving out to Middleburg from Miami for over 42 years, long before the big-box developments near Black Creek filled in. We know the difference between a 1978 ranch on a two-acre wooded lot with its original clay flue tiles and a 2012 prefab fireplace in a subdivision off Blanding Boulevard. The problems look different. The repairs are different. And the way Clay County’s humidity works on chimneys that sit idle ten months a year is different from anything you’ll find in a national chimney manual. That’s why Middleburg homeowners call us instead of a chain that dispatches from Orlando. Call (833) 974-6113 and a live person will answer, 24 hours a day.
Why Hearthstone Chimney Co. of Miami Is Middleburg’s Preferred Chimney Liner & Rebuild Company
Our reputation in Middleburg was built one chimney at a time, mostly through neighbors telling neighbors. We’ve relined flues on Pine Meadows Drive, rebuilt crowns near the Middleburg Historic District, and replaced rusted prefab flues in the newer subdivisions off County Road 218. Homeowners here don’t write as many online reviews as folks in Miami, but the ones we have received mention the same things: we show up when we say, we explain what we found in plain English, and we leave the work area cleaner than we found it.
Response time to Middleburg is typically same-day or next-day for liner and rebuild calls. Our technicians are based in Clay County and Duval County, not dispatched from a central warehouse two counties away. That matters when you’re smelling smoke in the living room or you’ve found raccoon droppings in the firebox three days before a cold snap.
We document every inspection with our Level-2 camera system. You see the photos. We give you a plain-English verdict. No scare tactics, no mystery. Just the condition of your flue, your options, and a written estimate with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Every job is backed by our 90-Day Done Right Promise, governed by the K.E.Y.S. values code: Krafted right, Every time, Your home first, Standing behind it. In writing. No arguing.
Our Chimney Liner & Rebuild Services in Middleburg
Stainless Steel Liner Installation
In Middleburg, a stainless steel liner is often the only permanent fix for clay flue tiles that have been compromised by decades of pine-resin creosote and moisture cycling. We install DuraFlex heavy-wall stainless steel liners with proper insulation packs to meet NFPA 211 standards for zero-clearance installation. For the ranch homes built in the 1970s and 1980s around Middleburg, this is typically a one-day job: we remove the damper, drop the liner down from the top, make the appliance connection, and seal the crown against water and wildlife intrusion. The liner carries a lifetime warranty when we install it. Done right, and we stand behind it.
Flexible Liner Systems
Not every Middleburg chimney is straight. The older masonry flues in homes off Henley Road and near the original Middleburg town center often have offsets from settling or from original construction that wasn’t plumb. A flexible liner navigates these bends without breaking the continuous flue-gas seal that rigid pipe cannot achieve. We size flexible liners using the appliance’s BTU output and the chimney’s actual interior dimensions, not a rule-of-thumb chart. This matters in Middleburg because many homeowners have added wood inserts to original fireplaces that were never designed for the heat output, and an undersized liner creates drafting problems that show up as smoke in the house.
Liner Replacement for Prefab Fireplaces
The 2000s-era subdivisions near Black Creek and along Long Bay Road are full of factory-built fireplaces with thin-gauge metal flues that rust from the outside in. Clay County’s humidity is the culprit, accelerated by chase covers that weren’t properly sealed against our afternoon thunderstorms. We replace these with OEM-compatible or upgraded flue systems from Olympia Chimney and Famco, and we weatherproof the chase so the new liner doesn’t suffer the same fate. This is not a liner job you want to defer: a rusted prefab flue can allow wall-void temperatures that create a real fire hazard.
Partial Chimney Rebuild
A partial rebuild addresses the section of chimney above the roofline: the crown, the wash, the top courses of brick, and sometimes the flue extension. In Middleburg, we see partial rebuilds needed most often on 1980s-1990s ranch homes where the crown cracked and water infiltrated the mortar joints during years of humid summers. Here’s the critical point: a partial rebuild that doesn’t fix the water infiltration at the crown will need redoing within one rainy season. We use poured concrete crowns with proper drip edges and expansion joints, not the thin mortar washes that were standard when these homes were built. We also install Gelco or Copperfield chimney caps with proper spark arrestors to keep out the raccoons and chimney swifts that are active in Middleburg’s wooded lots every fall.
Full Chimney Rebuild
When the masonry has deteriorated below the roofline, or when multiple flues in a shared chimney are compromised, a full rebuild is the only safe option. We’ve completed full rebuilds in Middleburg where the original chimney was so saturated with moisture from failed flashing and a missing crown that the interior wythes had turned to sand. A full rebuild gives us the chance to correct original construction errors: proper footing depth, adequate flue sizing for the appliance, and modern waterproofing that wasn’t available when the house was built. This is a multi-day job, and we protect the work area with tarps and scaffolding that respects your landscaping. We’ll be there when we say, every morning, until it’s finished.

Fast turnaround matters in Clay County, where a cold snap can arrive with forty-eight hours’ notice and a compromised chimney is not something you want to use anyway.
Common Chimney Liner & Rebuild Problems We See in Middleburg Homes
- Creosote-glazed clay tiles that brushing won’t clean. The loblolly pine and water oak that dominate Middleburg’s wooded lots produce resinous smoke that coats flue tiles with a dense, sticky residue. Standard brushing removes loose deposits but leaves the glazed layer, which reduces flue diameter and increases the risk of chimney fire. We use professional-grade chemical treatments or recommend a stainless steel liner to restore safe draft capacity.
- Factory-built prefab flues rusting from the outside in. The 2000s-era subdivisions near Black Creek have chase covers that weren’t weatherproofed against Clay County’s afternoon thunderstorms. Humidity enters the chase during the nine-month idle period and condenses on the steel flue, causing rust that penetrates from the exterior surface inward. By the time you see rust stains on the firebox, the flue is often perforated.
- Partial rebuilds that fail within a season because the crown wasn’t addressed. We’ve been called to Middleburg homes where another company rebuilt the top six courses of brick but poured a thin mortar wash for a crown. One rainy season later, the new mortar is spalling and the homeowner is back where they started. A square deal means doing the crown correctly the first time.
- Moisture-damaged liners in chimneys dormant ten months a year. Florida’s 90%-humidity summers allow moisture infiltration through cracked crowns and deteriorated flashing. In Middleburg, where chimneys often sit completely unused from March through December, that moisture accelerates mortar joint decay and causes clay tiles to spall from the inside out. The damage is invisible until a Level-2 camera inspection reveals it.
Pricing for Chimney Liner & Rebuild in Middleburg, FL
A typical stainless steel liner installation in Middleburg runs $2,200-$3,800 for a standard ranch-style fireplace with straight flue and accessible chimney top. Flexible liner systems with offsets or multiple bends range $2,800-$4,500. Prefab flue replacement in the 2000s-era subdivisions typically costs $1,800-$3,200 depending on chase access and whether the firebox surround needs modification.
Partial chimney rebuilds in Middleburg average $3,500-$5,500, with the wide range reflecting whether we’re addressing just the crown and top courses or rebuilding down to the roofline with new flashing. Full chimney rebuilds start around $6,500 and can reach $12,000+ for multi-flue systems with complex scaffolding requirements.
What moves the number: flue diameter and height, accessibility for our equipment, whether the firebox needs refractory repair, and the condition of the existing crown and flashing. We don’t guess.

FAQs - Chimney Liner & Rebuild in Middleburg
HeatShield cerfractory resurfacing works when the clay tiles are structurally intact but have minor cracking, spalling, or missing mortar joints. In Middleburg, we find that many 1970s-1980s ranch chimneys have tiles degraded beyond what resurfacing can salvage, especially where pine-resin creosote has trapped moisture against the liner surface for decades. We won’t recommend HeatShield if the tiles are shifting, if the flue has significant offset cracks, or if a camera inspection shows gaps that would allow flue gases to penetrate the masonry. When HeatShield is appropriate, it’s roughly $800-$1,500 less than a full stainless steel liner. We’ll show you the camera footage and give you an honest recommendation. Call (833) 974-6113 for a free inspection.
Factory-built fireplaces have factory-built flues, which are essentially metal liners built into the unit. You don’t add a separate liner, but the existing flue absolutely requires inspection and eventual replacement. In Middleburg’s 2000s-era subdivisions, we’ve replaced dozens of these factory flues that rusted through because the chase cover leaked and humidity condensed on the steel during long idle periods. “No liner needed” is technically true but dangerously incomplete if it ignores the condition of the factory flue itself. We inspect with a camera and tell you what we find. Estimates are free - call (833) 974-6113.
A partial rebuild in Middleburg typically runs $3,500-$5,500, while a full rebuild starts around $6,500 and can exceed $12,000 for complex multi-flue systems. The gap narrows when the chimney below the roofline also needs significant work: if we’re already scaffolding to the roof and the interior wythes are compromised, the labor savings of stopping at the roofline often don’t justify leaving deteriorated masonry in place. We show you the camera inspection of the full chimney height and explain where the break-even point sits for your specific situation. Every estimate is free and in writing - call (833) 974-6113.
Raccoon droppings in the firebox mean an animal has accessed the flue, which requires both removal of the animal and prevention of re-entry. The droppings themselves don’t indicate liner damage, but the same opening that admitted the raccoon has been admitting rain and humidity all summer, which does damage liners. We install proper chimney caps with animal guards, inspect the flue with our camera for moisture damage, and give you a plain-English verdict on whether the liner is still serviceable. In Middleburg, where chimneys sit idle long enough for raccoons to establish nurseries, this is a common fall call. Same-day service is usually available - call (833) 974-6113.
Oak and hickory produce less creosote than pine, but the practical reality in Middleburg is that most homeowners with wooded lots burn what’s available. If you’re burning pine, the critical factor is burning it hot and dry, with proper air supply, and having your flue inspected and swept annually. We’ve relined chimneys for homeowners who burned nothing but properly seasoned pine for thirty years with no problems, and we’ve found glazed creosote in chimneys where oak was burned wet and smoldering. The fuel matters less than the burning practice and the maintenance. That said, if you’re burning pine from your lot, we strongly recommend annual Level-2 inspections given Middleburg’s specific risk profile. Schedule yours at (833) 974-6113.
