Gelco Chimney Cleaning in Covina, CA | Glendale Chimney Sweep
We provide independent Gelco chimney cleaning and insert service across Covina’s 91722, 91723, and 91724 ZIP codes. Most calls we get from Covina homeowners start the same way: a Gelco insert that worked fine last winter won’t light after a long, idle summer. The one thing that makes our Gelco work here different is that we know exactly what Covina’s dry heat and settling clay-tile flues do to these units, and we inspect for it before we ever put a brush to the flue. Call (833) 467-6493 for a free estimate.
Glendale Chimney Sweep is an independent Gelco service provider. We’re not affiliated with the manufacturer, and we don’t pretend to be. What we are is a shop that has spent years pulling these inserts out of postwar Covina fireplaces, diagnosing what actually failed, and fixing it with parts we’re willing to name out loud. For full details on our Gelco sales & service work, see our brand page.
Why Covina Residents Choose Us for Gelco Service
Gelco fireplace inserts sit inside masonry fireplaces that were built when Eisenhower was president. The insert might be twenty years old, but the chimney around it is seventy. That distinction matters, and it’s one we’ve learned to respect by working on Gelco wood-burning inserts with glass bifold doors, Gelco gas inserts with millivolt standing pilots, and Gelco door and screen assemblies across Covina service area homes for years.
Noel Tarkanian, our owner, grew up in Glendale’s Montrose neighborhood with a 1950s fireplace that needed attention every winter. That’s where his understanding of how chimneys actually behave started, and it carried through his formal HVAC and sheet metal training before he moved exclusively into chimney work. He’s been cleaning and inspecting chimneys throughout the Glendale and San Gabriel Valley area for over a decade, and he’s built a reputation for telling people the truth about what their equipment needs. That’s true for Gelco owners in Covina as much as those needing Gelco service in Irwindale.
When we use OEM parts, we say OEM. When a part is discontinued and we need a quality aftermarket equivalent, we tell you that too. A clean chimney isn’t a luxury – it’s just basic fire safety.

Common Gelco Chimney Cleaning Problems We Solve in Covina
- Pilot won’t hold after a long idle summer. Gelco gas inserts use millivolt standing-pilot controls, and after months of no use, the pilot and thermocouple/thermopile assemblies foul. Covina’s hot, dry summers are the worst for this – the pilot orifice gets a fine coating, and when that first cold snap hits, the pilot drops out. We clean the pilot assembly, check the millivolt output, and replace what’s actually weak instead of throwing parts at it.
- Glazed creosote from idle Santa Ana months. A Gelco wood-burning insert that sits unused through Covina’s long dry season lets creosote harden and glaze. Once the winter burn days start, that glazed layer stays put and concentrates over a short, intense burning season. A stiff mechanical sweep and a Level 2 camera look are usually what’s needed – not a quick brush pass.
- Warped bifold door gaskets and stained glass. Gelco glass bifold doors use gaskets that dry out in the Santa Ana heat. Once the gasket shrinks, flue gases leak past the door frame and cloud the glass. Some Covina homeowners replace the glass, but if the hinge and gasket aren’t addressed, the new glass fogs up within a season.
- Insert-to-firebox leaks on settling clay-tile flues. Covina’s 1950s – 60s tract homes in the Hollenbeck and downtown blocks were built on expansive San Gabriel Valley soils that shift over decades. Clay-tile flues crack, the insert’s flue connection loosens, and gaps open where gases should never go. We camera the full run to find the actual breach.
- Rust and sag on grates, log retainers, and trim. Older Covina chimneys often have uncapped, unlined flues. First rain of the season, water runs straight down to the Gelco insert body. Grates rust, logs sag, and trim pulls away. We see this all over the 91722 and 91723 flats, and it’s usually fixable with the right Gelco grate and trim kit – once the water source is addressed with a proper cap.
Gelco Service in Covina: What Local Conditions Mean for Your Equipment
Covina’s burning season is short and intense. Fireplaces sit idle through the hottest, driest months – often from April through October – and the creosote inside hardens and glazes instead of flaking away. Then the first winter burn days arrive, and homeowners light up expecting the same fireplace that worked last March. It doesn’t. The glazed creosote stays cemented to the flue wall, and a Gelco insert’s draft suffers immediately. What a Gelco owner in Charter Oak or the Hollenbeck flats needs is not a quick brush but a methodical sweep with a Level 2 camera check, so we can see whether the creosote is surface-level or whether it’s bonded to a clay-tile liner that cracked long ago from soil movement. That’s the Covina-specific pattern we’ve learned to expect, and because we know to look for it, we catch problems before they become chimney-fire risks. For homeowners reading this in neighboring areas, our Gelco service in La Habra Heights page covers the different conditions up there.
Gelco Models & Products We Service in Covina
We work on Gelco wood-burning fireplace inserts with glass bifold doors, Gelco gas fireplace inserts with millivolt standing-pilot controls, Gelco fireplace glass door and screen assemblies for masonry fireboxes, and Gelco replacement grates and grate/insert trim kits. When controls, gaskets, glass, or grates need replacement, we source OEM Gelco parts where they’re still available. When OEM is discontinued, we use quality aftermarket equivalents and tell you before we install anything. We keep common gasket sizes, pilot assemblies, and grate hardware on hand for faster Covina turnaround, so we’re not waiting on a parts truck while your fireplace sits cold.

FAQs – Gelco Chimney Cleaning in Covina
Nine times out of ten in Covina, it’s the insert’s pilot assembly. Millivolt standing pilots foul during long idle stretches, and a dirty pilot orifice or weak thermopile will drop the pilot every time. We clean the pilot, test thermopile millivolt output, and replace what’s actually failed. But we also check the chimney while we’re there, because a cracked flue liner will change draft and compound the problem. Call (833) 467-6493 and we’ll diagnose it properly.
Yes, and here’s why: in Covina’s 1950s – 70s tract homes, settling clay-tile flue liners are so common that a routine sweep almost always uncovers something worth seeing on camera. A Level 2 camera inspection tells us whether the glazed creosote ends at the flue wall or whether the liner behind it is cracked and shifting. We won’t recommend the inspection if we don’t think it’s needed, but in our experience, Gelco insert owners in Covina benefit from it more often than not.
In Covina, the most common cause is an uncapped flue. Many 1950s – 70s chimneys here were never fitted with caps, so rain falls straight down the flue and lands on the insert body. We cap the flue, check for water damage to the grates and trim, and repair what’s rusted. It’s a fix we do routinely in the 91722 and 91723 flats, similar to our Citrus Gelco service. Call (833) 467-6493 and we’ll tell you what you’re actually dealing with.
Yes, usually without replacing the insert. We replace the gasket and hinge assembly, then clean or replace the glass depending on how badly it’s etched. Covina’s Santa Ana heat is brutal on door gaskets, and once they shrink, flue gases leak past the frame and fog the glass. Fixing the gasket is what prevents the new glass from clouding again.
Yes, and it’s the slope. Many 91724 homes in the Charter Oak hills sit on sloped lots that shift flue assemblies out of plumb over time. When the chimney isn’t plumb, the insert’s flue connection can separate, and draft changes. We see more insert-to-firebox connection issues up there than in the flats. A camera inspection tells us exactly what has moved and what hasn’t. Call (833) 467-6493 for a free estimate.
