Gelco Chimney Cleaning in Miami, FL | Ashby Chimney Miami
We’re an independent Gelco service provider cleaning and repairing Gelco fireplace and chimney systems across Miami, FL. We do not work for the manufacturer and we are not an authorized dealer, which means we tell you the truth about what your Gelco needs, whether that’s a simple sweeping or an honest conversation about replacement. Miami’s salt air, humidity, and wildlife make Gelco maintenance here different from anywhere else, and that’s exactly what this page covers. Call (850) 787-8597 to book our Chimney Sweep in Miami or a Gelco inspection.
Why Miami Residents Choose Us for Gelco Service
Gelco systems show up in every part of Miami, from older Coral Gables estates to stucco ranches in Kendall. Our crews work on Gelco G36, G48, and G60 units every month, and we know the ways they fail in this climate. Nathan Corliss, owner and lead technician at Ashby Chimney Miami, spent nearly three decades working fireplaces across South Florida before leading this team. He learned his trade at Los Angeles Trade-Technical College, then spent years cleaning and inspecting systems from Brickell high-rises to Coconut Grove homes built before anyone thought about stainless flue liners. That experience shows up in how we price and how we explain the work. We give you a written price before anything starts, use genuine Gelco parts when they’re available, and we show up when we say we will. If a repair fails inside the guarantee period, we return and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every single job.
What Miami homeowners tend to value most is that our technicians are background-checked and uniformed, so you know exactly who’s walking through your door. And when you call, a live person answers. Not a form. Not a callback queue. Day or night.

Common Gelco Chimney Cleaning Problems We Solve in Miami
Here’s what we actually find when we get up on a Miami roof or look inside a Gelco firebox. This list comes from years of field notes, not a brochure.
- Rust and corrosion of galvanized steel flue pipes. Miami’s salt-laden air accelerates rust on Gelco’s galvanized components, especially in homes within a few miles of Biscayne Bay or the Atlantic. We regularly see flue pipes that look fine from the living room but are flaking apart above the roofline.
- Moisture-induced spalling of refractory firebox panels. Miami’s high humidity works its way into the porous panels inside Gelco fireboxes. Over time, the panels crack and flake. We see this even in fireplaces that are never used, because the moisture doesn’t need a fire to do damage.
- Acidic creosote from unseasoned tropical hardwoods. A lot of Miami homeowners burn whatever wood is available, often tropical hardwoods that aren’t fully seasoned. That produces creosote with a sharper acidity than what you’d get from dry oak up north, and it clings to Gelco’s interior surfaces. It also smells worse.
- Damper warping and seal failure. Gelco dampers face two forces in Miami: repeated thermal expansion when a fireplace is occasionally lit on cool nights, and constant high indoor humidity the rest of the year. The result is warped dampers that don’t seal, letting air-conditioned air escape and moist outside air creep in.
- Iguanas and debris blocking the flue. This is the problem that surprises people new to Miami. In Coral Gables and Coconut Grove, older masonry and prefab chimneys without proper caps become iguana nesting spots. We remove the nests, clean the flue, and install screened caps so it doesn’t happen again.
Gelco Service in Miami: What Local Conditions Mean for Your Equipment
Here’s a fact that holds true for Miami in a way it doesn’t for Fort Lauderdale or West Palm Beach: a large share of the city’s fireplaces are decorative. Miami’s housing stock is full of mid-century ranches and contemporary stucco homes where the fireplace was built as a visual feature, not a heat source. Yet tropical storm debris still finds its way into those chimneys, and the humid, salt-heavy air still corrodes the metal parts even when a fire has never been lit. That combination means Gelco owners in Miami need annual inspections less for creosote removal and more for moisture control, rust prevention, and keeping wildlife out. We’ve cleaned decorative Gelco flues in Kendall that had three years of leaf litter and a rusted cap, all in a fireplace the owner swore had never been used. In Miami, the chimney doesn’t care whether you use it. The climate uses it anyway.
The practical takeaway: if you own a Gelco system in Miami and haven’t thought about it in years, at minimum get a Miami Chimney Inspection at the Level 2 standard. It will tell you whether the flue is intact, whether moisture is getting in, and whether the cap and damper are doing their jobs. That inspection is also when we flag whether waterproofing would extend the life of your crown and masonry.
Gelco Models & Products We Service in Miami
We service the Gelco G36, G48, and G60 fireplace models, along with the venting and chimney components that accompany them. When a part needs replacing, we use genuine Gelco components whenever they’re available, because fit and longevity matter more than saving a few dollars. For non-critical exterior parts like caps and flashings, we sometimes recommend a quality aftermarket option such as a stainless steel cap with a proper screen, which holds up better against Miami’s salt air than the original galvanized cap on many Gelco units. We keep common Gelco replacement parts stocked locally for faster turnaround across Miami, so you’re not waiting on a slow supply chain when your fireplace needs attention before a cool snap.
One distinction we make clearly: we are not authorized by Gelco and we don’t claim to be. We’re independent technicians who have worked on enough Gelco systems to know their quirks inside and out. That independence is what lets us tell you plainly when a repair makes sense and when replacement is the smarter move.

AfterGelco Service Pricing in Miami
Most chimney sweeps in Miami run between $150 and $350, depending on the condition of the flue, whether wildlife or debris removal is needed, and whether you’re adding an inspection. A Level 2 inspection, which includes camera work inside the flue, typically adds $100 to $250. Waterproofing and cap installation are separate, and we quote those in writing after we see your specific setup. Corroded flue pipes or cracked fireboxes are bigger jobs, and we’ll tell you honestly when replacement is the right call instead of pushing a patch. Every estimate is free. Call (850) 787-8597 and we’ll give you a written number before any work begins.

FAQs – Gelco Chimney Cleaning in Miami
Yes, it does. Salt particles in the air settle on metal components and accelerate rust, even when the fireplace sits unused. Miami’s humidity then keeps that moisture active for months at a time. We regularly find corroded flue pipes and rusted caps on Gelco units in homes where the fireplace has never been lit. An annual inspection is how you catch it before it becomes a replacement job. Call (850) 787-8597 to schedule one.
Yes, and we find them often. Older homes in Coral Gables and Coconut Grove frequently have chimneys without proper caps or with caps that have rusted through. Iguanas climb stucco walls and enter through the opening, then nest inside the flue. We removed an active iguana nest from a Gelco G36 in Coral Gables just last August, along with the moisture damage it had caused. Installing a stainless steel screened cap fixes the problem permanently. Call (850) 787-8597 for an inspection and cap quote.
The most common cause in Miami is creosote left behind from burning unseasoned tropical hardwoods. That creosote has a sharper acidity than what you’d get from properly dried oak, and it adheres to the interior surfaces of Gelco flues. A basic sweeping removes loose buildup, but acidic residue can require a deeper chemical treatment. If the smell persists, the issue could also be moisture in the firebox or a damper that’s no longer sealing. We diagnose this during a standard Gelco service call and show you what we find, including photos from our camera inspection. Call (850) 787-8597 to get it looked at.
Upgrade to stainless steel. Most Gelco units ship with galvanized caps, which corrode quickly in Miami’s salt air. Stainless steel costs more up front but lasts far longer in this climate. We recommend a stainless cap with a proper screen to keep out both rain and wildlife. Our team can source and install the right size for your Gelco flue. Call (850) 787-8597 for a written quote.
It depends on the depth and location of the cracks. Surface spalling on refractory panels can sometimes be addressed with a quality repair product, but if moisture has worked deep into the panels, which happens often in Miami’s humid air, replacement is usually the safer and more cost-effective route. We’ll show you camera evidence before recommending anything, so you never have to take our word on a repair you can’t see. Call (850) 787-8597 and we’ll give you an honest assessment in plain English.
