Why Flint Chimney Sweep Is Fleming Island’s Preferred Chimney Repair Company

Hank Delano leads our repair work, and he holds every job to The Garrison Standard: a written price before the first tool is touched, a camera inspection with photos you can see for yourself, and a 365-Day Done Right Promise in writing on every repair. That means if a covered repair fails within one full year, we return at no charge, no argument.

Fleming Island homeowners tell us the same thing over and over: they’ve had a chimney company quote one number on the phone, show up late, then “find” problems that double the price before any real work begins. We don’t run that playbook. The number we give you is the number on the invoice, and the photo report shows exactly what we found and what we did about it. Uniformed, background-checked technicians arrive inside the window we give you, and a live person answers the phone 24/7. That’s not marketing language. It’s how the Garrison Partners family has operated since 2002.

We know Fleming Island’s housing stock, too. The chimneys here run from 1990s builder-grade boxes in Eagle Harbor to older masonry stacks near the river, and the repair approach is different for each. That local knowledge plus a documented process is why this page exists: to give you straight answers before you ever pick up the phone.

Chimney Liner Installation in Fleming Island

Chimney liner installation in Fleming Island typically runs $1,800 – $2,900 on a standard single-story home, depending on flue length and liner diameter. A liner is the inner pipe that channels smoke and combustion gases safely out of the house. When it cracks, rusts through, or was never properly sized, you’re not just losing draft. You’re risking carbon monoxide and heat reaching combustible framing around the flue.

In a riverfront environment like Fleming Island, we regularly see liners fail earlier than the national average because salt-laden humidity from the St. Johns River works its way past a corroded cap or flashing, then sits against the liner metal. The result is flaking, pitting, and eventually pinholes that only show up under a camera.

Heavy creosote and a clogged flue in Fleming Island Plantation

On one job off Fleming Plantation Boulevard, the homeowner’s damper had seized and the flue was packed with second-degree creosote, a hard, tar-like glaze that burns hotter than a fireplace is designed to handle. We replaced the liner with a stainless unit because that’s what the chimney’s clearances and draft required, not because it’s the most expensive option. After the install, we ran a camera inspection and showed the homeowner a clear smoke chamber on the spot.

When does Fleming Island need a new liner?

You need a liner installed when the old one shows cracks, gaps, or corrosion, or when you’re converting from a fireplace to a heating appliance that requires a specific liner size. The clearest signals are flaking metal in the firebox, a persistent smoky smell after burns, or water staining on the flue walls. We won’t recommend a liner unless the camera shows you one is actually needed.

Chimney Flashing Repair in Fleming Island

Chimney flashing repair in Fleming Island typically runs $350 – $750. Flashing is the metal that seals the gap where the chimney meets the roofline. It takes the brunt of Florida’s rain, and here, it also takes salt mist off the St. Johns River, which accelerates corrosion compared to inland communities a few miles south.

The usual failure pattern we see in Fleming Island: the flashing rusts through at the corners, water follows the chimney down into the chase or the attic, and the first thing a homeowner notices is a stain on the ceiling near the fireplace, not on the roof itself. By then, water has already been moving for weeks. The fix is removing the old flashing, installing new step and counter flashing, and re-sealing the joint. We stock copper and galvanized flashing and specify the material based on what the chimney actually needs, not on what’s easiest to install.

What a proper flashing repair includes

We pull the old flashing, check the crown and cap for damage water may have caused on its way down, then install new flashing lapped to shed water away from the chimney body. Every flashing repair gets a camera pass so we can verify no water is already sitting inside the flue. You get photos of the finished work before we leave the driveway.

Patch or replace?

If the flashing is intact and only the sealant has failed, a reseal can work. But on Fleming Island riverfront homes, we more often find the metal itself has thinned enough that patching will fail again within a season. We’ll show you the corrosion in the camera images and let you decide with the actual condition in front of you. Either way, the price is in writing before work starts.

Trusted Brands We Service in Fleming Island

We work with Chimney Repair parts from Copperfield, DuraFlex, and Famco because these are the brands that hold up in a salt-humid Florida climate. Many Fleming Island chimneys were built with caps and dampers from these manufacturers, so we carry the replacement parts locally and can turn around a repair without a two-week parts delay from a distributor. When you call, ask which specific component your chimney needs and we’ll tell you what we plan to install by brand and model, in writing, before you commit to the job.

Common Chimney Repair Problems We See in Fleming Island Homes

• Corroded caps and dampers. Salt-laden air off the river eats through standard galvanized caps faster than inland communities see. A rusted cap lets rain straight into the flue, which is usually the first step toward a liner failure.
• Debris from live oaks and pines. Spanish moss, needles, and small branches collect on the chimney cap year-round in Fleming Island, not just in fall. A clogged cap reduces draft and hides the kind of cracks that only a Level 2 inspection catches.
• Spalling brick and cracked crowns. The sun-and-rain cycle here stresses the crown at the top of the chimney, and once water gets into the mortar joints, the brick face starts popping off. By the time you see spalling from the ground, the damage has been running for years.
• Leaky flashing at the roofline. Homes in Fleming Island Plantation, Eagle Harbor, and along Pine Avenue sit in the same weather path, and flashing takes the worst of it. A water stain near the fireplace often means the flashing, not the roof, is the entry point.
