Gelco Chimney Cap Installation in Orlando, FL

Gelco Chimney Cap Installation: The Orlando Owner’s Guide

Gelco chimney cap installation in Orlando typically runs $340-$680 for most single-flue models, including the cap, custom fitting, and weather-sealing, with same-day service available when you call before noon. We stock Gelco-compatible caps in 8″, 10″, 12″, and 13″ flue sizes on our trucks, and we carry the Gelco Ultra-Seal and Multi-Flue series in our Orlando warehouse for next-morning jobs. Most homeowners realize their cap has failed during our wet season, when water starts dripping down the flue or they spot rust streaks on the brickwork after a June thunderstorm rolls through.

Which Gelco Models This Applies To

Gelco caps break into three main series, and getting the right match matters because the mounting hardware differs. The Ultra-Seal line uses a tension-band clamp system that grips the flue tile directly; we see these on 80% of Orlando homes built between 1985 and 2005. The Multi-Flue series bolts to the chimney crown with corner brackets and covers two or more flues; these run larger, typically 24″ to 36″ wide, and require precise crown measurements because Gelco changed their bracket spacing in 2012. The Single-Flue series with outside-mount legs is less common here but still turns up in Winter Park and College Park bungalows with clay flue extensions.

To identify yours, check the stainless-steel label welded to the cap’s skirt; Gelco stamps the series name and nominal flue size there. If the label’s rusted off, measure the flue tile’s outside dimension with a tape measure, not the cap itself, since a cap can look right and still leak. We are an independent service provider with no affiliation to Gelco, but we install their caps exclusively because the 304 stainless holds up to Orlando’s salt-air humidity better than the discount-store 430-grade alternatives.

OEM Gelco caps run 15-20% more than quality aftermarket equivalents from Olympia Chimney or Famco, but the mounting hardware threads match exactly. Aftermarket caps sometimes skip the welded drip edge that Gelco uses to direct water away from the flue; in Orlando’s driving rain, that edge is worth the difference.

Signs Your Gelco Chimney Cap Is Failing

• Water stains on the firebox ceiling or smoke shelf. The cap’s mesh screen has corroded through or the lid has shifted in wind, letting rain run straight down the flue. In Orlando, this accelerates after caps sit through three or four hurricane seasons without inspection.
• Rust-colored streaks down the chimney face. The cap’s stainless skirt has begun to pit, usually at the weld points where the 304 grade thins first. Once pitting starts, the cap is shedding metal particles into the flue.
• Animals or nesting debris in the fireplace. The Gelco mesh has pulled away from its frame or a corner bracket has broken, creating a gap large enough for squirrels, roof rats, or the migratory starlings that nest in Orlando from February through July.
• The cap is visibly tilted or missing after a storm. Gelco’s tension-band clamps can loosen if the flue tile has minor spalling; the cap lifts in wind and lands crooked, or departs entirely. We replaced three caps after Hurricane Ian’s outer bands, all from the same Dr. Phillips neighborhood.
• Downdraft smoke even with the damper open. The cap’s lid has dented or the mesh has clogged with creosote flakes, disrupting the designed airflow pattern. This is common with Gelco caps that have never been removed for cleaning during a Level-2 inspection.

Replacement Cost & What’s Included

The spread depends on three things: cap series and size, whether your flue tile is sound enough to accept a tension band, and if the crown needs resealing before we bolt a Multi-Flue model down. We quote upfront after a quick look, and the number on the estimate is the number on the invoice. Every installation carries our 90-Day Done Right Promise in writing; if water gets past that cap, we come back, no paperwork and no arguing. A clean chimney is not a luxury - it is just the job done right.

DIY or Call Us?

An owner can safely check whether the cap is loose by sighting up from the firebox with a flashlight, or by binoculars from the ground. Do not climb the roof. Orlando’s clay tile roofs are unforgiving, and a cap replacement requires working at the flue edge with both hands while balancing. The tension-band clamp on Gelco Ultra-Seal models must seat evenly around the full flue circumference; a quarter-inch gap at the back, invisible from below, funnels water directly into the chimney. We have found caps that homeowners installed themselves sitting cockeyed because they did not realize the flue tile was octagonal, not round. If you are comfortable on a ladder and have solid footing, you can tighten a visible bolt. For anything involving the roofline, call us. Roy Dempsey has seen too many emergency room visits that started with “I just needed to check the cap.”
