This page is for homeowners who already have a Gelco liner or Gelco-branded chimney components and need honest answers about whether to repair, replace, or rebuild. We’ve worked on Gelco products across Orlando since 2014, from Winter Park colonials to College Park bungalows, and we know which Gelco series hold up in Central Florida’s humidity and which ones show their age.
How Gelco Products Fail - and How We Fix Them
- Gelco Stainless Pro series with crevice corrosion at the collar joint. In Orlando, the combination of high humidity and occasional hard rain pooling at the flue collar accelerates pitting where the liner meets the appliance adapter. We cut back to sound metal, install a Gelco-compatible collar with high-temp sealant rated to 2000°F, and pressure-test the joint before we leave.
- Gelco Flex-Liner with sagging in tall, uninsulated Orlando chimneys. The 304-alloy flex line in older Gelco kits loses tension across a two-story run, especially when the chimney sits on the south face of a house and cooks all afternoon. We pull a new DuraFlex or Gelco-compatible 316Ti flexible liner with proper insulation wrap, which prevents the droop that causes drafting problems and creosote pooling.
- Gelco Pre-Fab firebox panels cracked from thermal shock. These show up in 1990s Orlando tract homes in neighborhoods like Metrowest and Hunter’s Creek. The refractory panels crack when homeowners burn unseasoned oak, which is common here because green wood is cheap and plentiful. We source OEM Gelco panels or match the spec with HeatShield refractory mortar if the crack pattern allows, always documenting the repair with photos.
- Gelco chimney caps with failed mesh and rusted base rings. The standard galvanized caps that shipped with many Gelco systems in the 2000s rust through at the base ring in five to seven years in Orlando’s climate. We replace with a Gelco-compatible stainless cap or, if the flue is oversized, fabricate a copper or stainless cap that fits the actual dimensions, not the nominal size.
- Gelco liner with mortar joint failure in 1960s Orlando block chimneys. In neighborhoods like Rosemont and Azalea Park, the original parging inside the flue crumbles and the Gelco liner loses its central support. We perform a partial rebuild of the affected courses, re-parge with proper refractory mortar, and reinstall the liner with new top and bottom termination kits.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask about your Gelco model if you know it, the symptoms, and the home’s age and neighborhood.
- 2
Level-2 camera inspection. Our technician runs a camera the full length of the flue, photographs every defect, and gives you a plain-English verdict on whether you need liner repair, full replacement, or chimney rebuild work.
- 3
Parts decision. We stock Gelco-compatible components and also carry DuraFlex and HeatShield. If your Gelco part is obsolete, we explain the aftermarket equivalent and why it meets or exceeds the original spec. You see the parts before they go in.
- 4
The repair. Background-checked, uniformed technicians complete most Gelco liner and rebuild jobs in a single visit. We protect your floors, work cleanly, and do not leave until the system passes a draft and smoke test.
- 5
Documentation and guarantee. You receive photos of the completed work, a written invoice matching the upfront quote exactly, and the 90-Day Done Right Promise in writing. If it’s not right, we come back. No arguing.

Why Orlando Homeowners Call Hearthstone Chimney Co. of Orlando for Gelco Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more. That changes how you treat a customer.
Our technicians know Gelco products specifically, not just chimney liners in general. When a Gelco Stainless Pro shows corrosion at the collar, we don’t guess. We’ve seen it in Orlando’s climate dozens of times, and we know the fix. We also carry DuraFlex and HeatShield, so if your Gelco system needs a component that is no longer manufactured, we have a quality path forward that does not leave you stranded.
Every job carries the 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to file, no arguing. Roy Dempsey grew up in College Park working on his grandfather’s chimney, and he built this company on the idea that a clean chimney is not a luxury - it is just the job done right.
FAQs
No, as long as the repair uses Gelco-compatible or OEM parts and follows manufacturer installation guidelines. As an independent Gelco service provider, we document every repair with photos and part numbers so your warranty record is complete. If your original warranty has expired, our 90-Day Done Right Promise still covers the workmanship. Call (877) 565-7563 to discuss your specific warranty status.
Yes, for most lines. We stock Gelco-compatible collars, termination kits, and flex liners, and we work with suppliers who maintain inventory for discontinued series. For obsolete Gelco pre-fab firebox panels, we often use HeatShield refractory mortar or source a cross-referenced panel that matches the thermal rating exactly. We never substitute builder-grade parts.
Repair is cheaper when the damage is localized, such as a failed collar or a short crack in a refractory panel. Replacement is the better value when the liner shows multiple failure points, significant corrosion, or sagging across a long run. We give you both numbers during the free estimate so you can decide. Call (877) 565-7563 to schedule.
We answer calls live 24 hours a day, and we typically schedule inspections within one to two business days. Emergency situations, such as a blocked flue or visible chimney damage after a storm, get same-day or next-day priority. Most Gelco liner and rebuild jobs are completed in a single visit once scheduled.
Yes. We service and install DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield products. Many Orlando homes have mixed systems or a Gelco liner paired with another brand’s cap or firebox. Our technicians carry the full range of professional-grade parts and know the compatibility rules between brands.
