Gelco Damper Repair: The Orlando Owner’s Guide
Gelco damper repair in Orlando typically runs $280-$520 installed, depending on whether the throat plate, frame, or both need replacement. We stock Gelco-compatible damper assemblies and hardware on our trucks, and most repairs are completed same-day. You’ll usually notice the problem first in winter: the damper won’t fully open, won’t stay closed, or you feel a draft even when the fireplace is off.
Which Gelco Models This Applies To
Gelco manufactured dampers across several series, and the part you need depends on the age and throat size of your fireplace. The most common units we see in Orlando homes are the Gelco 8-inch and 13-inch throat dampers, along with the older Gelco cast-iron pivot dampers found in pre-1990 construction around College Park and Winter Park. Check the damper frame for a stamped model number, usually on the front lip or the pivot arm. If the stamp is rusted away, measure the throat opening width and depth, and note whether your damper is top-sealing (mounted at the chimney top) or throat-sealing (inside the firebox).
We carry both OEM Gelco replacement dampers and quality aftermarket equivalents from Copperfield that match Gelco specs. The aftermarket units fit the same throat dimensions and carry comparable warranties, though we default to OEM when the original frame is still sound and only the plate or spring assembly has failed. One compatibility gotcha: Gelco’s 13-inch throat damper from the 1980s used a slightly narrower pivot pin than later models. If your house was built during Orlando’s 1983-1987 construction boom, bring that pin measurement or let us check it on site. Mixing pin sizes will bind the damper within a season.
Signs Your Gelco Damper Repair Is Failing
- The damper sticks or requires force to open. Rust and creosote buildup on the Gelco pivot rod and throat plate are the usual culprits. In Orlando’s humidity, we’ve seen rods seize solid after just two seasons without use.
- You feel cold air dropping down the flue when the damper is closed. The Gelco seal plate has warped or the frame has corroded at the edges, breaking the metal-to-metal seal. This is common in homes near Lake Apopka where salt air accelerates oxidation.
- The damper won’t stay open on its own. The spring tension assembly or the notched control arm has worn out. Gelco’s spring steel holds up well, but the mounting bracket can crack from thermal cycling over twenty-plus years.
- You hear rattling or metal-on-metal noise when the wind blows. The throat plate has detached partially from its pivot, or the frame screws have backed out. This worsens quickly and can drop the plate into the firebox.
- Smoke spills into the room on startup. The damper is opening only partially, or the plate is hanging crooked in the throat. This is not a draft problem; it’s a mechanical failure that needs addressing before the next fire.
Replacement Cost & What’s Included
| Service | Price Range |
|---|---|
| Gelco damper plate replacement (OEM) | $280-$380 |
| Gelco damper frame and plate (full assembly) | $420-$520 |
| Pivot pin and spring hardware only | $180-$240 |
| Level-2 camera inspection with photos | $89 (with repair) |
What drives the range: accessibility of the throat (some Orlando ranch homes from the 1970s have tight firebox clearances), whether the existing frame is reusable, and whether we find secondary issues like a cracked smoke shelf. Our estimate is the number on the invoice. The 90-Day Done Right Promise covers the work in writing, no arguing. We also apply our standing $50 off any repair over $250, and there’s a permanent 5% senior and veteran discount.
DIY or Call Us?
You can safely check whether the damper opens and closes fully, and you can shine a flashlight up the throat to spot obvious rust or a detached plate. Do not attempt to remove or replace the damper assembly yourself. The throat plate is heavy cast iron, the spring-loaded pivot is under tension, and the work happens overhead in a confined space. We’ve been called to jobs where a homeowner dropped the plate into the firebox and cracked the firebrick, turning a $300 damper repair into a $900 rebuild. A clean chimney is not a luxury - it is just the job done right. For Gelco damper repair in Orlando, call us and we’ll handle it safely.
FAQs
A properly maintained Gelco damper typically lasts 20-30 years, though Orlando’s humidity and seasonal temperature swings can shorten that to 15-20 years if the chimney lacks a cap. The salt air in neighborhoods near the lakes or east toward Cape Canaveral accelerates corrosion at the pivot points. Call (877) 565-7563 for a free inspection - estimates are free.
Sometimes. If the frame is sound and only the spring, chain, or control arm has failed, we can replace those components. If the throat plate is warped or the frame is cracked, replacement is the only lasting fix. We document what we find with camera photos and give you a plain-English verdict. Call (877) 565-7563 for an exact quote - estimates are free.
Most Gelco damper replacements take 90 minutes to two hours from ladder set to cleanup, assuming standard accessibility. Tight clearances in older Orlando homes, or a smoke shelf that needs repair, can extend that. Our technicians arrive with parts and aim to finish in one visit. Call (877) 565-7563 to schedule.
