Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Gelco Chimney Cleaning in West Covina, CA
We provide independent Gelco chimney cleaning and gas fireplace service across West Covina, and the work here has a distinct character shaped by the city’s housing stock. Many homes in West Covina still run Gelco gas log sets or inserts that were installed during the big fireplace-to-gas conversion wave, and a lot of those units have not been properly cleaned or inspected since the day they went in. What sets our Gelco work apart is that we look at the whole system, the Gelco equipment and the masonry flue behind it, because in West Covina the two often fail together. Call (866) 361-2279 and we will walk you through what we check before we ever touch a brush to your chimney.

We are an independent service provider, not affiliated with or authorized by Gelco. That independence matters. We recommend what your firebox and flue actually need, not what a manufacturer program tells us to sell. Our familiarity with Gelco gas log sets, inserts, and firebox replacement units comes from years of pulling them out, cleaning them, and re-installing them in ranch-era masonry fireplaces across the San Gabriel Valley and West Covina. We know how these units actually fail around here, not just how the manual says they should work. If you’re dealing with a Gelco insert that won’t light, soot streaks on a vent-free log set, or a firebox smell that shows up on cold nights, you’re describing the calls we run week in and week out in the 91790, 91791, and 91792 neighborhoods.
Why West Covina Residents Choose Us for Gelco Service
Hector Olivares, our owner, grew up in Uptown Whittier and spent well over a decade in the trade across the San Gabriel Valley before starting Chimney Sweep Whittier in 2014. He learned combustion and venting through the HVAC and building systems programs at Rio Hondo College in Whittier, and that hands-on training shows in how we approach Gelco work in West Covina. We don’t just clean the glass and call it done. We check the pilot, the thermocouple, the burner, the combustion air path, and then we look at what’s behind the Gelco unit, the firebox and the flue, because that’s where the dangerous stuff hides.
West Covina homeowners call us because we carry professional-grade materials and we know how to use them. Our trucks are stocked around an intentional roster: DuraFlex for liner work, HeatShield for flue resurfacing, Gelco and Famco for termination hardware and caps, and Olympia Chimney and Copperfield supply lines for the components that go between them. Contractor-grade materials, not hardware-store substitutes. When we close out a Gelco service call, the unit goes back in with matched, purpose-built hardware and the flue gets flagged for anything a camera shows us. That’s the full scope we bring to every chimney in West Covina.

Common Gelco Chimney Cleaning Problems We Solve in West Covina
- Vent-free Gelco log sets sooting up older ranch fireboxes. Vent-free logs pull combustion air from the room, and in 1950s-era West Covina ranch homes the firebox often doesn’t get enough of it. The result is soot streaking and a firebox smell that homeowners mistake for a flue problem. We clean the soot, check the combustion air path, and tell you straight if the setup is safe to run as-is.
- Aftermarket Gelco inserts dumped into clay-tile flues without a proper liner connection. This was common during the 1980s and 1990s conversion wave. Exhaust leaks into the smoke chamber and attic, and the insert still looks fine from the front. We check the liner connection and flag exactly what a Level 2 camera inspection shows.
- Pilot and thermocouple assemblies that corrode during AQMD no-burn months. West Covina sits under South Coast Air Quality Management District no-burn rules, and many Gelco inserts go months without firing. The pilot clogs or the thermocouple corrodes, and the first cold evening of the season the unit simply won’t light. We carry replacement pilots and thermocouples that fit Gelco equipment.
- Decorative gas logs caked with years of carbon and dust. A gas log set is only decorative if it’s never cleaned. We pull the logs, clean the burner ports, remove the carbon buildup, and reset the log placement so the flame pattern is right again. This fixes the ghosting on the firebox walls and the smell when the set runs.
- Glass doors and screen enclosures that haven’t been removed in a decade. Gaskets dry out, clips break, and the glass gets a film that no glass cleaner handles. We service Gelco glass doors and enclosures, check the gasket seal, and replace what’s worn before we put the trim back on.
Gelco Service in West Covina: What Local Conditions Mean for Your Equipment
West Covina sits in the eastern San Gabriel Valley, where winter evenings get cold enough to use the fireplace but the region’s frequent AQMD no-burn days mean many chimneys sit idle for months at a stretch. That idle time is exactly when creosote hardens and pest nests settle into the flue, and birds and bees don’t care whether a chimney is connected to a wood fire or a Gelco gas insert. Then there’s the 2008 Chino Hills earthquake. In the hillside tracts near South Hills and the older homes off Cameron Avenue, it’s common to find clay flue liners cracked by the quake. A standard sweep alone won’t catch offset gaps in a clay liner, and an offset gap is exactly how combustion byproducts leak into an attic. This is why we push Level 2 camera inspections on Gelco inserts that were retrofit into those flues. The Gelco unit may be perfectly fine, but the flue behind it isn’t, and you need to see the camera footage to know which is which.
Gelco Models & Products We Service in West Covina
We clean, service, and repair the Gelco products we see throughout West Covina: vented and vent-free gas log sets, gas fireplace inserts built for masonry fireplaces, prefab and universal firebox replacement units, and fireplace glass doors and screen enclosures. When a Gelco burner, pilot, thermocouple, or log set needs replacement, we match quality parts that fit the unit, and we use quality aftermarket gas valves and refractory components when an OEM part has been discontinued. We’ll tell you honestly when a Gelco insert is worth servicing and when the firebox behind it needs repair before any gas work makes sense. There’s no point reinstalling a clean burner into a cracked clay flue, and we won’t pretend otherwise.

AfterGelco Service Pricing in West Covina
The cost of Gelco chimney cleaning and service in West Covina depends on what we find once we’re in front of the firebox. A straightforward cleaning of a gas log set and burner runs less than a service call on a Gelco insert that needs a new thermocouple, pilot, or gas valve. What drives the price: the condition of the unit, the number of parts that need replacement, and whether we need to run a Level 2 camera inspection on the flue behind it. Every job starts with a free written estimate, and the estimate sets the final price before any work begins. No surprises. Call (866) 361-2279 for a specific quote on your Gelco unit in West Covina, and we’ll give you a number you can plan around.

FAQs – Gelco Chimney Cleaning in West Covina
The pilot or thermocouple has likely corroded or clogged during the idle months. West Covina’s no-burn season keeps gas inserts off for long stretches, and the small gas ports in the pilot assembly collect dust and corrosion. We clean or replace the pilot and thermocouple, and we check the gas valve before we walk away. Call (866) 361-2279 to schedule a service call and we’ll get the unit lighting again.
If your Gelco insert was retrofit into a masonry flue, especially in the hillside tracts near South Hills or the older homes off Cameron Avenue, you should absolutely have a Level 2 camera inspection. The 2008 Chino Hills earthquake cracked clay liners throughout those areas, and a camera run is the only way to see offset gaps before they become a carbon monoxide path into the attic. We include the camera footage in our report so you can see exactly what we see.
Most vent-free Gelco log sets can be cleaned and serviced without replacement. We pull the logs, clean the burner ports, check the oxygen depletion sensor, and reinstall the set with the correct log placement. Replacement only makes sense when the burner itself is corroded or a part has been discontinued with no workable substitute.
If the smell hangs around when the logs are off, it’s usually carbon and dust baked onto the logs and burner, or a cracked clay liner behind the firebox letting combustion residue drift back in. In West Covina’s ranch-era homes, both possibilities are real. We clean the Gelco set first and run a camera if the smell persists. Call (866) 361-2279 and we’ll sort out the source.
That depends on the firebox dimensions and the condition of the clay flue behind it. Many West Covina homes from the 1950s and 1960s can accept a Gelco insert, but the liner connection is where most retrofits fail. We measure the firebox, inspect the flue, and tell you whether the insert can be installed safely without relining work. If the flue needs a DuraFlex liner, we’ll show you the camera footage to prove it. Estimates are free, so call (866) 361-2279 for a straight answer on your specific fireplace.
