Gelco Chimney Repair in Jacksonville, FL

Gelco Chimney Repair in Jacksonville: What to Know First

We provide independent Gelco chimney repair in Jacksonville, and most jobs are completed in a single visit with upfront pricing that matches the final invoice. Gelco’s stainless steel chimney caps, chase covers, and liner systems hold up well in our climate, but when mortar joints fail or brick spalls, the repair needs to account for how Gelco components integrate with the masonry beneath them. We’re not affiliated with Gelco, but we’ve worked on their products across the First Coast for over two decades, from the riverfront homes of Ortega to the newer builds in Nocatee. Call (833) 974-6113 anytime, day or night - a live person answers, and we’ll schedule a free estimate at your convenience.

How Gelco Products Fail - and How We Fix Them

• Gelco chimney cap mesh corrosion on coastal properties. The Model C and Multi-Flue series use 18/8 stainless mesh that can pit within 8-12 years when salt air settles on dew-heavy mornings, especially in Atlantic Beach and Ponte Vedra. We replace with 304-grade mesh or full caps, depending on flue configuration, and document the before condition with photos you’ll see.
• Chase cover corner splits on Gelco pre-fab chase systems. The stamped steel covers on older Gelco chases develop stress cracks at the corners where thermal expansion meets our freeze-thaw cycles, rare but real in Jacksonville’s January cold snaps. We fabricate a replacement from heavier-gauge steel or copper, sealed with proper counter-flashing, not caulk.
• Liner collar separation in Gelco UltraPro installations. The connection collar between the liner top and the cap can work loose when the chimney settles, which happens more than people expect in our sandy soils near the St. Johns River. We reseat with proper Gelco-compatible hardware or transition to a DuraFlex or HeatShield solution if the original part is no longer produced.
• Spalling brick beneath Gelco caps due to trapped moisture. Gelco’s tight-fitting cap designs shed water well, but when the crown underneath was poured flat or cracked, water gets trapped against the brick. We see this in San Marco bungalows and Arlington ranches alike. The fix is crown repair or rebuild, then reinstallation of the existing cap if it’s sound, with weep details that let the masonry breathe.
• Flashing gaps where Gelco chase meets the roofline. The factory flashing on Gelco wood-frame chases often outlasts the sealant, but not the step flashing integration with asphalt shingles. Our Jacksonville roofers’ license allows us to remove and replace shingles properly, install new step and counter-flashing, and seal with a product rated for our UV exposure, not the hardware-store stuff that cakes in eighteen months.

Why Jacksonville Homeowners Call Hearthstone Chimney Co. of Jacksonville for Gelco Work

We’ve been at this since 2014, and Dale Brinson grew up in Ortega watching chimneys he now services. That matters because Jacksonville’s older neighborhoods have quirks, sandy soils, and salt air that a national chain’s script won’t catch. Our technicians are background-checked, uniformed, and trained on Gelco’s product line alongside DuraFlex, HeatShield, and the other professional-grade brands we carry. The 90-Day Done Right Promise is in writing, not a handshake. A live person answers the phone at midnight on a Saturday because chimney problems don’t wait for business hours. If it’s worth burning wood in, it’s worth doing the maintenance right. That’s how we’ve operated for over 42 years, and it’s how we’ll be here when you need us again.
