Fast, Reliable Chimney Liner & Rebuild Across Sanibel
Chimney liner and rebuild work on Sanibel Island demands a technician who understands salt air, not just soot. A standard liner that holds up fine in Fort Myers can corrode through in half the time here, and a rebuild done with mainland methods often misses the moisture traps that Gulf humidity creates in low-use chimneys. We’ve been crossing the causeway to provide Sanibel Fireplace Services for decades, and our trucks carry marine-grade materials specifically for island conditions. If your chimney was damaged in Ian’s rebuild or you’re seeing rust stains on the chase, we’ll come out, document what we find with photos you’ll see on the spot, and give you an upfront number before any work starts.

Why Hearthstone Chimney Co. Is Sanibel’s Preferred Chimney Liner & Rebuild Company
Sanibel homeowners don’t call us because we’re flashy. They call because we’ve been here long enough to remember when Periwinkle Way was two lanes, and because our technicians know which post-Ian rebuilds used emergency flashing that is already curling at the edges. Over 42 years, we’ve earned a strong local reputation across Lee County, and Sanibel customers specifically tell us they chose Hearthstone because we explain the problem in plain English and put the guarantee in writing.
Our response time to Sanibel is typically same-day or next-day. We don’t subcontract to crews who need GPS to find Middle Gulf Drive. Our background-checked, uniformed technicians carry DuraFlex and Olympia Chimney liner stock sized for the elevated, higher-end homes that dominate Sanibel’s rebuilt neighborhoods. The 90-Day Done Right Promise applies to every job on the island - in writing, no arguing, no paperwork chase. If it’s not right, we make it right. That’s the Keystone Standard, and it’s how we’ve operated since 1984.
Our Chimney Liner & Rebuild Services in Sanibel
Stainless Steel Liner Installation
Stainless steel liners in Sanibel fight a battle that inland chimneys never see. The 316Ti alloy we use from DuraFlex resists salt-air pitting far better than standard 304, but even the best metal needs proper sealing at the crown and collar to keep Gulf spray from working down the flue. We size every liner to the appliance - whether it’s a decorative wood-burning fireplace in a Sea Oats home or a gas insert in a rebuilt Gulf Shores property - and we document the fit with camera photos you’ll see before we close up.
Flexible Liner Systems
Sanibel’s older elevated homes and the tighter chase dimensions common in post-Ian construction often leave no straight shot for rigid pipe. Flexible liners from Olympia Chimney let us navigate offset flues without dismantling finished chase enclosures, which matters when you’re working in a home on West Gulf Drive where every square foot of interior finish is custom. We pull these with a winch, seal the top with a marine-rated cap, and back the install with our 90-Day Done Right Promise.
Liner Replacement
Most Sanibel chimneys we inspect for liner replacement aren’t failed from heat - they’re deteriorated from moisture and salt. A liner that sat through ten months of humid idle time develops pinholes at the joints, then condensation seeps into surrounding masonry. We pull the old liner with a Level-2 camera inspection first, so you see exactly where the breach is. Replacement typically runs one visit, with no-hassle upfront pricing that doesn’t change when we’re on the ladder.
Partial Chimney Rebuild
After Hurricane Ian, many Sanibel chimneys needed partial rebuilds of the crown, chase top, or upper courses where wind-driven water found its way in. We still see emergency repairs from 2022-2023 that used incompatible sealants or skipped the through-wall flashing. Our partial rebuilds use HeatShield refractory mortar for the crown and proper drip edges on the cap, built to shed Gulf rain rather than trap it. We also handle full Chimney Repair in Sanibel for structural issues beyond the liner zone.

Trusted Brands We Service in Sanibel
We don’t guess at what works in marine air. Our trucks stock DuraFlex flexible and rigid liners, Olympia Chimney termination caps and adaptors, and Famco dampers and collars - all specified for coastal corrosion resistance. For crown and rebuild work, we use HeatShield refractory mortar and Gelco stainless chase covers. Because we keep inventory on the truck, most Sanibel jobs don’t wait for parts to cross the causeway. That’s how we finish in a single visit, and it’s why our upfront estimate holds - no “we’ll be back next week” surprises.
Common Chimney Liner & Rebuild Problems We See in Sanibel Homes
- Salt-accelerated cap and damper corrosion. Sanibel’s direct Gulf exposure pits galvanized and even standard stainless components in three to five years. We replace these with 316Ti or marine-rated hardware that lasts.
- Moisture-trapped flues in low-use chimneys. Fireplaces here may burn twice a year. That idle time lets humidity condense inside the liner, breeding mold and spalling mortar. We inspect for this specifically, not just creosote.
- Failed post-Ian emergency seals. Rebuild crews in 2022-2024 often used silicone or urethane caulks incompatible with masonry heat cycles. We’re now seeing these crowns crack and separate - a problem that demands partial rebuild, not just re-caulk.
- Wildlife nesting in uncapped flues. Chimneys sitting cold for months attract osprey debris, raccoons, and the occasional snake. Our liner installs include proper screening that keeps animals out without blocking draft.
Regular Chimney Cleaning & Sweep in Sanibel helps us catch these issues before they require full rebuilds, though on this island the inspection focus is corrosion and moisture, not soot.
Pricing for Chimney Liner & Rebuild in Sanibel, FL
Sanibel’s market runs higher than mainland Lee County for liner and rebuild work, partly because of causeway travel and partly because elevated, custom homes demand more time and marine-grade materials. Here’s what we typically see:
| Service | Typical Range in Sanibel |
|---|---|
| Flexible stainless liner install (standard fireplace) | $2,800 - $4,200 |
| Rigid stainless liner install (straight flue, gas appliance) | $2,200 - $3,400 |
| Liner replacement (remove and reline) | $2,400 - $3,800 |
| Partial rebuild (crown, upper courses, cap) | $1,800 - $3,500 |
| Full chimney rebuild (elevated home, chase included) | $6,500 - $12,000 |
What moves the number: flue height on elevated homes, access (scaffolding vs. ladder), whether the chase is stucco or siding, and whether post-Ian damage requires structural repair beyond the liner zone. We don’t quote over a blurry photo. We come out, run the camera, show you what we found, and give one number that doesn’t change. Estimates are free. Call (844) 803-1545.

Yes, we service the full island, including Gulf Shores, Sea Oats, Middle Gulf Drive, and the Periwinkle Way corridor. Post-Ian rebuilds in these neighborhoods often have chase configurations and emergency repair histories that differ from original construction, and we document those conditions in every inspection.
Our phones are staffed by a live person 24 hours a day, 7 days a week, and we dispatch for true emergencies - structural damage, active water intrusion, or blocked flues - as rapidly as causeway access allows. For non-urgent liner or rebuild work, we schedule during regular hours to avoid after-hours rates.

Every job carries our 90-Day Done Right Promise in writing - if it’s not right, we come back with no arguing and no paperwork.
