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 Fontana, CA | Lantern Chimney Sweep
We provide independent Gelco chimney cleaning and repair across Fontana, and the work here has a particular shape to it. Most of the homes we service in Fontana are post-war ranch tracts built for Kaiser Steel workers, and their original Gelco dampers and caps have been quietly failing for decades. If you own one of those homes in 92335 or 92336, call (855) 341-8132 and we’ll tell you exactly what’s happening inside that flue before we touch anything.
We’re not a Gelco dealer or authorized affiliate. We’re an independent chimney company that has repaired enough Gelco fireplaces in the Inland Empire to know where they fail and what fixes actually hold up. Gelco sales & service work runs through our hands constantly, and the difference between a factory-trained rep and a working chimney tech is that we see what these units do after twenty years in a Fontana summer. That’s the knowledge that matters.
Why Fontana Residents Choose Us for Gelco Service
Gelco fireplace systems are common in Fontana’s original ranch housing, and most of them haven’t seen a professional in years. Homeowners call us because the damper won’t budge, the gas insert pilot won’t stay lit, or they’ve been told by a home inspector that the flue needs attention before closing. We understand what they’re dealing with because we’ve worked on these same 1950s and 60s homes up and down the 92335 and 92336 ZIP codes.
Len Castorena owns Lantern Chimney Sweep, and he grew up in Pomona’s Lincoln Park neighborhood, which means he’s spent a lifetime around the same housing stock we service in Fontana. The fundamentals he learned at Mt. San Antonio College gave him the building-systems background, but it’s the nearly three decades of hands-on chimney work that tells him what a seized Gelco damper sounds like before he even gets up on the roof. We use OEM Gelco parts for safety components like thermocouples and damper assemblies when they’re available, and we keep the common wear items on the truck so a Fontana job doesn’t stall waiting on a gasket. We tell you what we found, and we can fix it.

Common Gelco Chimney Cleaning Problems We Solve in Fontana
- Seized Gelco damper assemblies. Fontana’s hot, dry summers bake the original damper pivot pins and tracks until they corrode and lock up. This shows up constantly in the 1950s to 70s ranch homes where the fireplace has sat capped and unused for months at a time. We free them when possible and replace the assembly when the metal’s too far gone.
- Pilot outages on Gelco gas inserts. Santa Ana winds drive fine dust and ash down through the flue and into the pilot assembly. Homeowners fire up the insert on the first cold night in fall and the pilot won’t hold. Usually it’s a thermocouple that’s been slowly cooked or fouled, and we replace it with an OEM component.
- Spalled refractory panels. Long idle periods followed by sudden thermal cycling crack the firebox panels on Gelco inserts. The damage hides behind the log set until a Level 2 inspection brings it into view. We check for this specifically on every Gelco cleaning.
- Rusted spark arrestors and missing caps. The original Gelco caps on older Fontana masonry chimneys rust off decades ago. South Fontana tracts are full of open flues packed with bird nests and leaf litter. A cap-and-sweep job is the single most common call we run in this part of town.
- Obstructed flues from years of disuse. Inland Empire heat means the fireplace sits idle most of the year. Creosote from the last burn seasons hardens and debris accumulates unseen. Dry Santa Ana winds push soot back down the flue. By the time the first cold-weather burn happens, the obstruction is real.
Gelco Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s post-war ranch homes in ZIPs 92335 and 92336 were built for Kaiser Steel workers, and many still have the original Gelco-style dampers that seize from decades of disuse and heat. That’s the sentence that separates Fontana from every neighboring city. In Rancho Cucamonga, the housing stock trends newer and the fireplaces are often prefab metal boxes. In Fontana, the original masonry chimneys with clay tile liners and Gelco damper assemblies are still in place, and they’ve been sitting through forty or fifty Inland Empire summers. The heat doesn’t just age the metal. It dries out the lubricants, bakes the pivot pins, and leaves the damper frozen in whatever position it held when someone last closed it in the 1980s. When the Santa Ana winds push dust down those uncapped flues, whatever wasn’t seized gets coated. Homeowners who’ve never touched the damper since buying the house call us in fall, expecting a simple sweep, and we end up replacing the assembly. That’s Fontana’s version of chimney work, and we plan for it on every Gelco job we book here.
Gelco Models & Products We Service in Fontana
We service the standard Gelco wood-burning fireplace insert, the Gelco gas fireplace insert with millivolt control, Gelco direct-vent gas fireplaces, and the original Gelco masonry fireplace damper assemblies still sitting in Fontana’s older homes. Our parts approach is straightforward. For safety-critical components like thermocouples, pilot assemblies, and damper mechanisms, we use OEM Gelco parts when they’re available. For wear items like gaskets and cap hardware, we’ll use high-quality aftermarket equivalents when they meet the same spec. We keep the common Gelco service parts stocked for fast Fontana turnaround, because nobody wants to wait three weeks for a damper when the first burn of the season is a week away.

FAQs – Gelco Chimney Cleaning in Fontana
The pilot assembly is the first place to look. In Fontana, Santa Ana winds push dust and ash down the flue onto the thermocouple, which reads the pilot flame and tells the gas valve to stay open. Once it’s fouled or cooked, the pilot drops out. Check that the pilot flame is actually strong and steady. If it’s weak or yellow, the thermocouple is likely the problem. Call (855) 341-8132 and we’ll diagnose it on-site with an OEM replacement.
Yes, they’re one of the most common findings we document in the older tracts near South Fontana. The original Gelco in Glen Avon spark arrestors and caps rusted off decades ago, leaving open flues that birds and squirrels treat like a ready-made cavity. We regularly pull nests, leaf litter, and crumbled clay tile out of these flues before sweeping. The fix is straightforward: clear the flue, sweep to bare tile or metal, then install a new multi-flue cap so it doesn’t repeat.
Depends on what’s frozen. If the pivot pins are just corroded, we can often free the damper, clean the tracks, and have it working smoothly in under an hour. If the metal is cracked, warped, or the pins have snapped, replacement is the honest fix. We carry OEM-compatible Gelco in Pedley damper assemblies for the common sizes in Fontana’s ranch homes, so the repair usually happens same visit. Call (855) 341-8132 and we’ll give you a straight answer once we see it.
Yes, and it’s a big part of our fall workload in Fontana. Units that sat idle through years of Inland Empire heat need more than a quick dusting. We inspect the pilot assembly, thermocouple, burner, and venting, then do a full sweep of the flue. Spalled refractory panels are common on inserts that cycle hot and cold after long idle periods, so we check the firebox closely. Specifics depend on what we find, but most of these units can be returned to safe operation in a single visit.
Yes. We install Gelco in Rialto chimney caps and multi-flue covers on Fontana masonry chimneys regularly. The original caps on 1950s and 60s homes are almost always rusted through by now, and the flue below has been open to rain, birds, and debris. We’ll measure the flue, recommend the right cap for your fireplace and climate, and install it after the sweep. Call (855) 341-8132 for a free estimate on cap replacement.
