Gelco Chimney Cleaning in Windemere, TX | Boardwalk Chimney Sweep
We provide Chimney Sweep – Windemere and independent Gelco chimney cleaning and service across Windemere, TX, and the thing that sets our work here apart is simple: we know what the live oak and juniper canopy does to uncapped Gelco vents. Most “smoky fireplace” calls in the 78764 ZIP trace back to debris blockage, not a dirty firebox. If you own a Gelco insert in Windemere, call (877) 274-1247 for a straight diagnosis and a free estimate.
Boardwalk Chimney Sweep works exclusively with the material brands chimney professionals specify: Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. We repair what we inspect, and we’re an independent service provider, not an authorized Gelco dealer. That independence means we tell you plainly when a flue just needs a sweep and when a cracked firebox is past saving.
Why Windemere Residents Choose Us for Gelco Service
Brent Holloway, our owner, spent years working every kind of flue you find in the Hill Country: clay-tile liners, stainless steel inserts, the old double-wall metal systems that went up when a lot of these lakeside houses were built in the eighties and nineties. He picked up the fundamentals through the HVAC and building systems program at Austin Community College’s Riverside Campus, and he’s lived in the Lake Travis Highlands long enough to remember when half these neighborhoods were cedar scrub. That’s the background we bring to Gelco in Jollyville and Windemere specifically.
We’ve cleaned and inspected enough Gelco fireplace inserts, glass doors, and venting in this ZIP that we know how these units actually age in Hill Country homes, not just how the manual says they should. When you call us for Gelco sales & service, you get a crew that can look at a standing-pilot gas insert and tell you whether it’s a clogged orifice or a thermocouple failing. And we use OEM Gelco parts for safety-critical components: glass gaskets, latches, dampers, pilot and thermocouple assemblies. For standard venting and caps, we’ll use quality aftermarket where fit and listing allow. That’s the honest repair-versus-replace stance Windemere homeowners deserve.

Common Gelco Chimney Cleaning Problems We Solve in Windemere
Windemere’s specific conditions create specific Gelco failure patterns. Here’s what we pull out of these units week after week:
- Glass-door gasket and latch failure. Central Texas heat hardens the gaskets and latches on Gelco wood inserts. The result is smoke and creosote odor bleeding into the room even when the fireplace has been idle for months. We replace these with OEM Gelco gaskets so the door seals the way it did from the factory.
- Standing-pilot gas inserts that won’t stay lit. After a long summer sitting idle, Gelco gas inserts with millivolt controls develop clogged pilot orifices and failed thermocouple or pilot assemblies. The homeowner lights it, the flame holds for twenty seconds, then it’s out. We clean the pilot, test the thermocouple, and replace what’s actually bad, not the whole valve train.
- Cracked damper and refractory panels after hard freezes. Windemere’s rare freeze snaps, coming after months of disuse, crack masonry crowns and flue tiles. Inside the insert, refractory panels and dampers spall. We inspect for freeze damage as part of every Level 2 inspection, because it’s the kind of thing that hides until you light the first fire of the season.
- Debris-blocked flues from uncapped vents. Gelco direct-vent and B-vent termination caps that were never installed, or that have shifted, collect live-oak leaves, acorns, and squirrel nests. Draft goes bad, fires backdraft, and the owner thinks the insert itself is failing. We remove the blockage and install a properly sized cap.
- Glazed creosote from long idle seasons. When fireplaces sit unused through the hot months, creosote left from the last burn dries and glazes. That hardened layer is harder to remove and more likely to ignite than fresh soot. Windemere’s usage pattern, heavy use in the short winter then months of nothing, makes glazed creosote a regular finding.
Gelco Service in Windemere: What Local Conditions Mean for Your Equipment
Here’s the thing about Windemere that doesn’t show up in the Gelco manual: the live oak and juniper canopy overhangs a lot of roofs in this community, and the tall exterior chimneys common on 1980s and 2000s Hill Country-style homes catch more wind-driven debris and rain intrusion than shorter, sheltered flues. When a Gelco insert goes uncapped, or the cap is damaged, acorns drop straight down the flue. Squirrels and birds build nests against the damper. We’ve pulled a full squirrel nest and a fistful of acorns from a single flue on a wooded lot just off the 78764 stretch of Windemere. The homeowner called about a Gelco wood insert that smoked into the room every time they lit it. The firebox wasn’t dirty. The flue was blocked. We swept the glazed creosote, installed a properly sized cap on that tall exterior chimney, and the insert drafted clean. We also noted the hardened glass-door gasket for a follow-up replacement, because the heat had taken it.
That’s the pattern here: months of idle use, debris loading from the tree canopy, and occasional freeze damage, all landing at once. It’s why so many Windemere homeowners who think their Gelco insert is failing actually have a blocked or damaged venting system. A Level 2 inspection with a camera tells you which one it is.
Gelco Models & Products We Service in Windemere
We service the Gelco product lines most common in Windemere homes: wood-burning fireplace inserts with glass-door fronts, gas fireplace inserts with millivolt standing-pilot controls, Gelco fireplace glass door and screen enclosure sets, and Gelco direct-vent and B-vent termination caps and venting kits. For safety-critical components like glass gaskets, latches, dampers, and pilot or thermocouple assemblies, we use OEM Gelco parts. For standard venting and caps, we use quality aftermarket parts where the fit and listing allow. That approach keeps your Gelco insert running with the components it was designed for while avoiding unnecessary expense on basic vent components. The same brands chimney professionals specify are the ones we stock, so we’re not waiting on a parts order for routine Dryer Vent Cleaning – Windemere and service calls.

FAQs – Gelco Chimney Cleaning in Windemere
Your Gelco insert is almost certainly drafting against a debris-blocked flue, not a failing firebox. Windemere’s live oak and juniper canopy drops leaves and acorns into uncapped vents, and squirrels build nests against the damper during the long idle season. The smoke backs up because the flue can’t pull air. We clear the blockage, sweep the glazed creosote behind it, and install a cap so it doesn’t happen again. Call (877) 274-1247 and we’ll bring the camera to prove what’s in there.
The most common cause is a clogged pilot orifice or a failing thermocouple in the standing-pilot assembly. Months of disuse let dust and tiny debris settle into the pilot tube, and the thermocouple’s millivolt output drops as it ages. We clean the pilot, test the thermocouple’s output, and replace only the component that’s actually bad using OEM Gelco parts. You don’t need a whole new valve, most of the time. Call (877) 274-1247 to get it diagnosed before the first cold snap.
Absolutely, and for Windemere specifically it’s one of the most cost-effective things you can do. Uncapped or damaged vent terminations on Gelco direct-vent and B-vent systems collect live-oak leaves, acorns, and squirrel nests. The blockage kills draft and creates exactly the smoky-backdraft complaints we see most often in this ZIP. A properly sized cap keeps the debris out and the animals out. We can install one on the same visit as your sweep.
It can, and it’s one of the freeze-related failures we see in Windemere homes with exterior chimneys. After months of sitting idle, the sudden cold stresses masonry crowns and flue tiles, and inside the firebox, refractory panels and dampers can crack or spall. The damage isn’t always visible until you light a fire, and a cracked refractory is a safety problem. That’s why we include refractory and damper inspection in every Level 2. If it’s cracked, we tell you plainly whether repair or replacement is the safer call.
Once a year, minimum, for a wood-burning Gelco insert in regular use during the winter. Windemere’s long idle season means the creosote from last season’s burns dries and glazes while the fireplace sits unused, and glaze is harder to remove and more flammable than fresh soot. Add the tree-canopy debris, and an annual sweep plus inspection is cheap insurance. Gas Gelco inserts can go every two years for inspection and venting checks, but if you skipped last season, call (877) 274-1247 now and get on the schedule before burning season.
