Gelco has built a solid name in chimney protection, particularly for their cap and crown systems. We’ve worked on hundreds of Gelco units across Jacksonville over the past four decades, offering our Chimney Cleaning & Sweep services, from the historic masonry chimneys in Riverside and Avondale to the prefab fireplace systems in Mandarin and Arlington. That volume matters. We know how Gelco caps fail in humid subtropical air, which crown coatings hold up, and when a damper rod is worth freeing versus replacing.
We are not affiliated with or authorized by Gelco. We are an independent service provider with deep hands-on experience. Dale Brinson, our owner, grew up in Ortega watching older chimneys do their work, and he’s spent more than twenty years finding problems other sweeps missed. If it’s worth burning wood in, it’s worth doing the Chimney Repair maintenance right.
Why Trust Hearthstone Chimney Co. of Jacksonville for Your Gelco Chimney Cleaning?
Our technicians know Gelco products from field experience, not from a catalog. We’ve replaced Gelco Round Top Caps on bungalows in Springfield, installed Gelco Multi-Flue Caps on Southside two-stories, and freed seized damper rods in 1980s prefab units from the consolidation-era building boom. That history means we spot the failure before it becomes an emergency.
We source OEM Gelco replacement parts directly from authorized distributors for caps and crowns. When Gelco stock is unavailable, we recommend quality aftermarket alternatives that meet or exceed original specifications, and we explain the trade-off plainly. Our Level-2 camera inspections end with photos you can see and a plain-English verdict, documented like an engineer, explained like a craftsman.
Dale Brinson picked up this trade through Florida State College at Jacksonville’s vocational programs, then spent years alongside experienced sweeps before founding Hearthstone Chimney Co. in 1984. His wife still keeps a list of the odd things he’s pulled from flues. That list is longer than it has any right to be. We bring that same curiosity and thoroughness to every Gelco service call in Jacksonville.
Background-checked, uniformed technicians. No-hassle upfront pricing. The number on the estimate is the number on the invoice. And if it’s not done right, we make it right, in writing, no arguing.
Common Gelco Chimney Cleaning Problems We Fix in Jacksonville
- Gelco caps rusting at welded seams. Jacksonville’s humid coastal air, with year-round relative humidity often above 70%, attacks the welded joints on Gelco Round Top Caps and Heavy-Duty Flue Caps from the inside out. We see this most on homes within a few miles of the St. Johns River or the Intracoastal, where salt air accelerates the corrosion. A rusted seam looks minor until rainwater starts entering the flue, saturating creosote and damaging the firebox below. We replace the cap and inspect the flue for hidden moisture damage.
- Gelco crown coatings cracking from thermal stress. The handful of winter fires most Jacksonville homeowners light each year creates a brutal cycle: the crown heats rapidly, cools overnight, and sits damp the rest of the year. Gelco crown coatings develop hairline fractures, then wider cracks that funnel water straight to the chimney structure. Our repair process addresses the underlying moisture issue, not just the surface crack.
- Gelco damper rods seizing in older models. Humidity plus intermittent use equals a stuck damper. We’ve freed rods in Gelco units from the 1980s and 1990s that hadn’t moved in years. Sometimes a thorough cleaning and lubrication restores function. Sometimes the rod or frame is too corroded, and we recommend a quality aftermarket replacement with better stainless steel construction.
- Gelco spark arrestor mesh clogging with heavy creosote. Jacksonville’s damp flues don’t draft as efficiently as dry-climate chimneys. Incomplete combustion leaves heavier creosote deposits that clog the fine mesh on Gelco cap screens. A blocked spark arrestor is a fire hazard and a code violation. We remove the screen, clean or replace it, and inspect the flue for glazed creosote that requires mechanical removal.
- Cracked refractory panels in prefab units beneath Gelco caps. We serviced a home in Mandarin with a Gelco Round Top Cap that had rusted through at the seam, allowing rain to enter the flue. We removed the old cap, installed a new Gelco Heavy-Duty Flue Cap with a stainless steel screen, and cleaned heavy creosote buildup from the firebox. The homeowner now has a watertight, safe chimney. This is typical of what we find: the cap fails first, the water damage follows, and the owner is surprised because they only lit four or five fires last winter.
Gelco Parts & Our Repair-vs-Replace Approach
We stock OEM Gelco replacement caps, screens, and crown coating materials locally for fast turnaround on Jacksonville service calls. When a Gelco component is structurally sound, we repair: a rusted screen gets replaced, a stuck damper gets cleaned and freed, a cracked crown coating gets removed and reapplied. We replace only when repair is false economy.
A Gelco cap with surface rust but intact seams and solid welds earns a coating treatment and a new screen. A cap with rust-through at the seam, or a crown with structural cracking that exposes the chimney crown beneath, gets replaced. We explain the difference before we start, and the price we quote is the price you pay.

Our Gelco Service Process - Step by Step

Diagnosis with camera inspection. We run a Level-2 camera inspection of your Gelco chimney system, focusing on cap seam integrity, crown condition, damper operation, and flue deposits. You see the photos. We give you a plain-English verdict.
- 2
Repair or install with OEM-compatible parts. We use genuine Gelco replacement parts when available, or quality aftermarket alternatives we trust. No builder-grade substitutes. Technicians carry common Gelco cap sizes and screen configurations on their trucks.
- 3
Test and verify. We operate the damper, verify cap fit and screen tension, and confirm proper draft. If we replaced a crown coating, we check curing per manufacturer specifications.
- 4
Warranty documentation. Every Gelco service is backed by our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork to dig up, no argument.

FAQs - Gelco Chimney Cleaning Service in Jacksonville
Is Hearthstone Chimney Co. of Jacksonville authorized by Gelco?
No. We are an independent service provider with extensive hands-on experience repairing and maintaining Gelco chimney products. We source OEM Gelco parts through authorized distributors, but we are not affiliated with or endorsed by Gelco.
Gelco caps are known for rusting - do you use any coating to extend their life?
We apply a high-temperature, humidity-resistant coating to Gelco caps after cleaning and surface preparation, particularly on units showing early seam corrosion. This is not a factory Gelco treatment; it’s a field-applied protective step we’ve developed for Jacksonville’s coastal climate. It adds two to four years of service life in most cases. Call (833) 974-6113 to schedule.
My Gelco multi-flue cap is over 10 years old and has a lot of surface rust. Can you repair it or must I replace the entire cap?
Surface rust without seam penetration or structural weakening typically qualifies for repair: we clean, treat, coat, and replace the screen. If the welds are failing or the base metal is thinning, replacement is the honest recommendation. We show you the difference on camera before you decide. Call (833) 974-6113 for a free evaluation.
I have a Gelco damper that is stuck closed. Is this a common issue?
Yes, particularly on Gelco dampers in prefab fireplaces from the 1980s and 1990s that see intermittent use. Jacksonville’s humidity causes the rod and frame to corrode together. We can often free the mechanism with professional cleaning and lubrication. If the rod is bent or the frame corroded through, we install a quality aftermarket stainless steel damper. Call (833) 974-6113 to book a technician.
Do you carry Gelco-specific spark arrestor screens for my cap?
We stock replacement screens for Gelco Round Top, Heavy-Duty Flue, and Multi-Flue Caps in common mesh sizes. If your cap uses an unusual configuration, we source it within 48 hours or fabricate a compatible screen that meets code. Call (833) 974-6113 with your cap model or dimensions.
After a chimney fire, is a Gelco crown typically salvageable?
It depends on the fire intensity and duration. A minor chimney fire may leave the Gelco crown coating cracked but the underlying crown intact; we remove the damaged coating, inspect the masonry, and reapply. A significant fire can compromise the crown structurally or damage the flue liner beneath, requiring replacement. Our camera inspection determines which path is right. Call (833) 974-6113 for an urgent post-fire inspection.
How much does Gelco chimney cleaning cost in Jacksonville?
Gelco chimney cleaning and inspection in Jacksonville typically runs $189 to $289 for a standard sweep with Level-2 camera inspection. Gelco cap replacement ranges from $340 to $580 depending on model and flue configuration. Crown repair coating application runs $280 to $450. These are upfront prices; the estimate we give is the invoice you receive. Seniors and veterans receive a permanent 5% discount. Call (833) 974-6113 for an exact quote - estimates are free.
