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.

AfterGelco Chimney Cleaning in Miami, CA | Flint Chimney Sweep
We’re Flint Chimney Sweep, and we provide independent Gelco chimney cleaning, Miami Chimney Inspection, and repair across Miami, FL. The short version: we work on Gelco HeatFlo gas fireplaces, EZ Stack chimney systems, Slim Line wood fireplaces, and Flex Vent liners every week here, and the one thing that separates our Gelco work in Miami from anywhere else is salt. Ocean air chews through steel firebox components and vent terminations faster than most homeowners expect, so we don’t treat a Miami Gelco unit like one sitting in a dry inland house. Call (830) 251-4560 for a written estimate before any work starts.
Why Miami Residents Choose Us for Gelco Service
Most chimney companies in Miami will sweep a flue and call it a day. We go further on Gelco equipment because Hank Delano, our owner, built Flint Chimney Sweep around a simple rule: tell the homeowner exactly what’s happening inside their firebox, show them the camera footage, and put the price in writing before a tool comes off the truck. Hank grew up in Eagle Rock and trained through the building maintenance and construction technology program at Los Angeles Trade-Technical College. He’s spent years doing hands-on chimney work, and that’s the lens we bring to every Gelco fireplace, insert, and venting system we touch in Miami.
We’re not a manufacturer-authorized service provider, and we won’t pretend to be. What we are is a local crew that’s stripped down, inspected, and repaired enough Gelco units in South Florida to know the failure patterns before we even pull the baffle. Our Gelco sales & service work spans the full range, from zero-clearance wood fireplaces to direct-vent gas systems, and we carry the sealing materials, camera equipment, and replacement components to handle what Miami’s climate does to them.
Common Gelco Chimney Cleaning Problems We Solve in Miami
- Salt corrosion on Gelco firebox steel and vent terminations. This is the big one in Miami. Ocean air carries fine salt particles that settle on steel and accelerate rust. We see pitting and flaking on Gelco HeatFlo gas fireplace interiors and EZ Stack terminations that many homeowners write off as cosmetic. It isn’t always. Once the corrosion reaches the point where the firebox wall thins or the vent joint weakens, you’re looking at a safety issue, not a surface blemish.
- Blocked direct-vent air intake vents. Gelco direct-vent gas fireplaces pull combustion air from outside. In Miami, wind-driven sand, lawn debris, and insect nests wedge into those intake passages all the time. The result is flame roll-out and soot staining on the glass. We clear the intake, inspect the burner, and confirm the flame pattern is stable before we leave.
- Cracked refractory panels in Gelco Slim Line wood fireplaces. Miami’s burning season is short, which means these units sit dormant most of the year and then get fired up with whatever wood is lying around. Construction scrap and treated lumber burn hotter and dirtier, and the thermal shock cracks the refractory panels. We replace those panels and advise on what to burn, not just what to sweep.
- Storm-damaged Gelco chimney caps and storm collars. Wind uplift during tropical storms dislodges caps and collars all over Miami. A missing cap lets rain pour down the flue, rusting the inner liner and the damper frame. We see this constantly during the May to October rainy season.
- Sticky creosote glaze from high-humidity burning. Miami’s humidity means creosote doesn’t always dry into the flaky form you get in dry climates. It often stays gummy and adhesive, clinging to the flue walls in a thick glaze. That glaze is a chimney fire waiting to happen, and it takes mechanical removal, not just a brush pass.
Gelco Service in Miami: What Local Conditions Mean for Your Equipment
Here’s the local reality that doesn’t show up on a generic chimney blog. Miami’s rainy season runs May through October with near-daily afternoon downpours. That means Gelco chimney caps and crown coatings here take far more water than in drier cities, even other parts of Florida. We routinely pull rusted-out fireboxes and find spalling brick all over neighborhoods like Little Havana, Allapattah, and Flagami, and the origin is almost always the same: a single missing or loose cap during a summer storm. Water gets in, sits in the flue, and the damage compounds for months before anyone notices. Compare that to a Gelco unit in a dry inland market, where a loose cap might go years without consequence. In Miami, water intrusion is a fast-moving problem, and the repair is always cheaper the week you notice it than six months later. Our Miami service area coverage means we’re already working in these neighborhoods every week, seeing the same storm patterns, the same salt exposure, and the same Gelco failure modes repeat.
Gelco Models & Products We Service in Miami
We service the Gelco product lines we see in Miami homes most often:
- Gelco HeatFlo direct-vent gas fireplaces – including salt-corroded terminations and blocked intakes.
- Gelco EZ Stack Class A chimney systems – storm-damaged caps, collars, and flashing.
- Gelco Slim Line zero-clearance wood fireplaces – cracked refractory panels, warped grate bars, and damper issues.
- Gelco Flex Vent liner kits – rusted or separated sections, especially after water intrusion.
When a Gelco part fails, we source OEM-equivalent replacement components like firebox panels, dampers, and vent caps whenever they’re available. If a part is discontinued or on lengthy backorder, we use high-grade aftermarket stainless or aluminized alternatives. We don’t gamble on cheap knockoffs. And if a Gelco unit has structural firebox damage or obsolete venting, we’ll tell you plainly that a full replacement is the safe call rather than patching it and hoping. That’s the Flint standard, and it applies to every Gelco chimney cleaning and repair job in Miami.
Gelco Service Pricing in Miami
A standard Gelco chimney cleaning and inspection in Miami typically runs between $180 and $340, depending on the unit type and what we find. Gas fireplace service with intake cleaning and burner inspection is usually on the lower end. A wood-burning Gelco Slim Line with heavy creosote glaze will run higher because the mechanical removal takes longer. If we uncover a damaged damper, rusted cap, or cracked refractory panel, those repairs are quoted separately, in writing, before we start. You’ll never get a surprise invoice from Flint Chimney Sweep. Every job gets a written price first, and every repair carries our 365-Day Done Right Promise: if it fails within a year, we return at no charge. Call (830) 251-4560 for a free estimate, and we’ll tell you the ballpark before we even book the truck.

FAQs – Gelco Chimney Cleaning in Miami
Once a year, even if you only burn during the short cool season, schedule our Chimney Sweep in Miami. Miami’s humidity keeps creosote sticky and adhesive rather than flaky and dry, so buildup doesn’t fall off on its own the way it might in a dry climate. A sticky glaze accumulates quickly and becomes harder to remove the longer it sits. If you burn construction scrap or pressure-treated wood, sweep twice a year. Call (830) 251-4560 and we’ll set it up.
The rotten egg smell comes from mercaptan, the odorant added to natural gas, and it usually means incomplete combustion or a venting problem. On Gelco direct-vent gas fireplaces in Miami, we most often trace it to a blocked air intake vent, a corroded vent termination, or a burner that needs cleaning. These are not issues to ignore. Gas work has real risk, so our technicians carry camera equipment to inspect the full vent path and combustion analyzer to confirm the flame is burning correctly before we call it fixed.
Frequently, yes. We source OEM-equivalent Gelco replacement parts whenever they’re still available, and when a part is discontinued, we use high-grade aftermarket stainless or aluminized components that fit the original specifications. We’ll confirm the exact part your unit needs before we quote, and we’ll tell you if the damage is extensive enough that a full replacement makes more sense than a parts swap.
Not necessarily. If the cap is intact but the mounting bracket is loose or the storm collar separated, we can often re-secure it and seal the joint. If the cap itself is bent, rusted, or missing pieces, a new cap is the correct fix. Either way, don’t wait through Miami’s rainy season. Rain entering an uncapped flue rusts the inner liner and damper frame, and that repair is much bigger than a cap. Call (830) 251-4560 for a written quote.
Yes, and it’s worse in Miami than in inland Florida. Salt particles settle on the liner and combine with humidity to form a corrosive film that attacks even stainless steel over time. We see pitting and thinning on Gelco liners within a decade of coastal exposure. Regular inspections catch it early, while waterproofing treatments and proper caps slow it down. A damaged liner is a carbon monoxide risk and a fire risk, so this isn’t cosmetic.

We were called to a 1950s ranch house in Little Havana where the homeowner’s Gelco Slim Line wood fireplace smelled smoky even when idle. Our tech pulled the baffle and found a heavy creosote glaze sitting on top of a rusted-through damper frame. We swept the flue, removed the failed damper, installed a new stainless assembly with a tight seal, and coated the crown to stop further water entry. That’s the kind of detail we bring to every Gelco job in Miami. Tell me what you’re seeing, I’ll tell you what it means. Call (830) 251-4560 for your free estimate.
