Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Repair Across Treasure Island
Chimney repair in Treasure Island typically runs $350 – $1,800 depending on what we find: mortar repointing starts around $350 – $800, flashing repair runs $450 – $950, and a full chimney rebuild can reach $1,500 – $3,000. Most Treasure Island repair jobs are scheduled within 5 – 10 business days, not because we’re slow but because coastal masonry work needs dry weather and the right materials. We know this city’s chimneys, its salt air, and the way Gulf moisture works into mortar joints faster than anywhere inland. If you’re seeing spalling brick, a rusted damper, or water staining around the firebox, call (830) 251-4560 and we’ll walk you through what you’re looking at before anyone books a truck.
Why Flint Chimney Sweep Is Treasure Island’s Preferred Chimney Repair Company
We’ve been repairing chimneys on Treasure Island long enough to know that the salt moving off the Gulf is the single most aggressive thing working against your masonry. It gets into the mortar, the damper, the flashing, and the crown. Homeowners here call us after noticing brick faces popping off, white crust forming on the chimney exterior, or a fireplace that suddenly won’t draft. Our crews arrive in uniform, background-checked, with a written price in hand before any tool comes off the truck.
Hank Delano leads our repair team, and every job he signs off on carries the 365-Day Done Right Promise. That means the written guarantee is part of the invoice, not a verbal promise. If a covered repair fails within one full year, we return at no charge. No argument, no re-bid. Treasure Island homeowners have told us that’s the reason they called us instead of the last company they tried.
We also stock the parts and materials that Treasure Island’s coastal chimneys actually need: stainless liners, stainless flashing, high-bond mortar, and coating systems rated for salt exposure. When we tell you a DuraFlex liner or a HeatShield resurfacing job is the right call, it’s because the material matches the failure mode we documented with the camera. You’ll see the photos yourself.
Chimney Repair Companies in Treasure Island
Chimney repair companies in Treasure Island range from one-man operations with a ladder to full-service shops like Flint Chimney Sweep that carry insurance, written guarantees, and camera inspection equipment on every truck. The job itself involves fixing what’s broken in the system that carries smoke and exhaust safely out of your house: the flue liner, the smoke chamber, the crown, the flashing, the damper, or the masonry shell. You call a chimney repair company when you see cracked brick, water in the firebox, rust streaks, or when a Chimney Repair inspection turns up damage you can’t see from the ground.
On Treasure Island specifically, the call usually starts with water. It’s moving through a failed crown or corroded flashing, and by the time it shows up inside, the damage is already underway. A standard repair here runs $350 – $1,800; a full rebuild with new liner and crown can reach $3,000. We give you that range in writing before work starts, and the invoice matches.
Flue Liner Replacement
Flue relining is replacing the inner liner that channels smoke safely out of the house. In Treasure Island, the old clay tile liners crack from decades of salt air and thermal cycling, and a cracked liner is a genuine fire and carbon monoxide risk. We install DuraFlex stainless liners, which handle the coastal corrosion far better than clay.
Chimney Crown and Damper Repair
The crown is the concrete cap on top of the chimney; when it cracks, water gets in and freezes, and spalling starts. Here it’s accelerated by salt. We repair crowns with materials rated for coastal exposure and replace rusted dampers with stainless units that actually close, so you’re not losing conditioned air up the chimney all summer.
Chimney Masonry Repair in Treasure Island
Chimney masonry repair in Treasure Island is the work we do most often, because the salt-laden Gulf air attacks mortar joints and brick faces in a way that doesn’t happen inland. You’ll see mortar crumbling out between bricks (repointing), brick faces popping off (spalling), or the chimney leaning slightly from years of moisture intrusion. Masonry repair restores the structural soundness of the chimney and stops water from getting behind the bricks, which is what turns a $500 repointing job into a $2,500 rebuild.
We do tuckpointing, spalling brick replacement, chimney waterproofing, and partial or full rebuilding. Prices for Chimney Repair in Treasure Island masonry work typically run: repointing $350 – $800, spalling brick replacement $450 – $1,200, waterproofing $350 – $700, and a full rebuild from the roofline up starts around $1,500. The figure you get before work starts is the figure on the invoice.
Salt-Driven Spalling Repair
Spalling is when the brick face pops off because moisture inside the brick expands and fractures it. On Treasure Island, salt crystals do the same thing with more aggression. We cut out the damaged brick, install new units matched to your chimney’s color, and repoint the surrounding joints with high-bond mortar that flexes slightly instead of cracking at the first thermal shift.
Chimney Waterproofing With Coastal-Grade Sealers
Waterproofing isn’t paint and it isn’t a fix for structural cracks. It’s a vapor-permeable sealer applied after we’ve repaired the crown and repointed the joints, so water can’t get in but the masonry can still breathe. We use Gelco and Olympia Chimney products, both rated for repeated salt exposure. A proper waterproofing job on Treasure Island adds years to the chimney.
Trusted Brands We Service in Treasure Island
We install and service materials from DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield. Those names matter because a chimney near the Gulf has to handle salt, wind-driven rain, and tropical storm pressure. A cheap big-box flashing or thin-gauge liner fails here within a few seasons. When we specify a Gelco crown coat or an Olympia water repellent, it’s because that product is designed to take the salt and keep taking it. We keep common Treasure Island sizes and components stocked, which cuts turnaround on liner jobs and damper replacements by days compared to special-order shops.
Common Chimney Repair Problems We See in Treasure Island Homes
- Rusted dampers that won’t close: Salt air gets into the throat damper and rusts the mechanism open or shut. If it’s stuck open, you’re paying to cool Gulf air all summer; if it’s stuck shut, you’ve got no draft. We replace with stainless.
- Spalling brick from salt-laden moisture: The chimney faces on the Gulf side of a home deteriorate years faster than the protected side. If you see brick chips in the gutter or on the patio under the chimney, the face has already started failing.
- Storm-blown caps and animal entry: A chimney cap that rusts out or blows off in a tropical storm lets rain, birds, and raccoons straight into the flue. That wet organic material accelerates creosote buildup and blocks draft. We install stainless caps sized to your flue.
- Flashing failure at the roofline: The metal where the chimney meets the roof takes the brunt of wind-driven salt rain. Once it lifts or corrodes, water runs down the chimney chase and into the ceiling below. We replace flashing with stainless or copper, sealed properly, not just caulked over.
One job stands out from a canal-front home near the Treasure Island Causeway. We opened the firebox and found the damper rusted open and the crown spalling from years of salt air. After a Level 2 camera inspection, we installed a Gelco stainless liner and repaired the crown. The homeowner got a photo report showing the before-and-after, and a chimney that drafts correctly for the first time in years.

FAQs About Chimney Repair in Treasure Island
Once a year, and on Treasure Island specifically that annual inspection catches salt-driven deterioration before it becomes a structural repair. The National Fire Protection Association recommends annual chimney inspections for all homes, but coastal homes here benefit more than most because the salt air works year-round on mortar, flashing, and dampers. If you burn fires regularly, or if a tropical storm has come through, schedule an inspection regardless of the calendar. Call (830) 251-4560 and we’ll schedule a Level 1 or Level 2 inspection with photo documentation.
A camera inspection shows the inside of the flue liner and smoke chamber, where most fire and carbon monoxide hazards live but where a visual check from the roof or firebox can’t see. It documents cracks in clay tile liners, third-degree creosote, gaps in mortar joints, and animal nests. On Treasure Island, it also shows salt corrosion inside metal liners that looks fine from the outside. You get the photos. When we recommend a repair, you’re seeing the same image we’re seeing, not taking anyone’s word for it.
Depends on the repair. Cracked crowns, failing flashing, and spalling brick should not wait, because every extra Florida rain season drives water deeper and raises the eventual cost. A minor mortar touch-up or waterproofing, if the chimney is otherwise sound and not used, can sometimes wait a few months. We’ll tell you straight: nothing gets recommended on this page or in your home that can’t be backed by camera evidence. If we say it can wait, we’ll say so plainly. Call (830) 251-4560 for an honest assessment.
We stop work and we show you the camera. Then we write a change order with the new price, and you approve it or don’t. The flat price you approved before the job started covers the scope we quoted; anything found mid-repair gets documented, photographed, and priced in writing before we touch it. No surprises on the invoice. That’s the Garrison Standard, and it’s non-negotiable on every job we book in Treasure Island.
Third-degree creosote looks like a hard, shiny, tar-like glaze coating the flue walls, and it’s the most fire-hazardous form of creosote buildup. It usually forms from low-temperature fires, unseasoned wood, or restricted air. It can sometimes be removed with professional rotary cleaning equipment, but in many Treasure Island chimneys the salt-corroded liner underneath means removal alone isn’t enough, and the liner needs replacement. A camera inspection tells you which situation you have. Call (830) 251-4560 and we’ll check.
