Gelco Chimney Cleaning in Van Nuys, CA | Corona Chimney Sweep
We clean and service Gelco fireplaces and inserts throughout Van Nuys, including the older tracts where these units have been heating homes since the 1950s and 60s. What makes our Gelco work different here is simple: we know the specific ways Van Nuys’ long hot off-season and older housing stock affect these particular fireplaces, and we repair what we find rather than handing you a referral. Call (855) 382-6159 for a free estimate.
Corona Chimney Sweep is an independent Gelco service provider, not a factory-authorized agent. We’ve serviced hundreds of Gelco direct-vent gas units, wood-burning inserts, and prefab metal fireplaces across the San Fernando Valley, including Sherman Oaks Gelco service calls. That independence means we’re free to tell you when a repair makes sense and when replacement is the honest answer, without a manufacturer’s sales quota in the background. Our experience with Gelco’s model-specific quirks is what lets us diagnose fast and fix right the first time.
Why Van Nuys Residents Choose Us for Gelco Service
Van Nuys has a lot of Gelco equipment still in service. The 1940s through 1960s ranch and tract homes that dominate the area were built when prefab metal fireplaces and inserts were the affordable option, and Gelco was one of the brands contractors installed by the pallet. Nolan Ferris, our owner, grew up around this housing stock in South Corona where the same construction patterns hold, and he’s spent over a decade pulling apart Gelco dampers, chase covers, and cap assemblies in the field. He doesn’t guess at a problem; he takes the unit apart until he can show you exactly what failed and why.
We carry OEM Gelco parts for critical components like dampers and caps, and we use high-quality aftermarket equivalents for universal items like flashing and spark arrestors where they perform just as well. The point is fit and safety, not pushing a manufacturer part number when a better option costs less. And because we work Van Nuys weekly — and handle Gelco service in North Hills too — we keep the common Gelco-specific wear items on the truck, which means fewer second trips.

Common Gelco Chimney Cleaning Problems We Solve in Van Nuys
- Seized damper assemblies on Gelco wood-burning inserts. Van Nuys summers run hot and dry, and a fireplace can sit unused from April to November. Creosote left from last winter hardens, and the damper mechanism seizes. We free them, replace the assembly when the metal’s too far gone, and make sure the draft is right before we leave.
- Cracked refractory panels and firebox seams on Gelco prefab units. When a fireplace goes from months of disuse to nightly winter fires, the thermal cycling is brutal on the cement-board panels inside the firebox. Hairline cracks are normal wear, but wider gaps behind the refractory can expose the metal shell to direct flame. On a Gelco prefab, that’s a repair we address the same visit, not a note on an invoice.
- Rusted or missing spark arrestor screens on original Gelco chimney caps. The 1950s and 60s homes around Van Nuys still have their original caps on many roofs. Those screens rust through, and once there’s a hole, birds get in and build nests in the flue. We find this constantly on the older tracts. Cap replacement clears the blockage and keeps it from coming back next spring.
- Deteriorated chase covers on Gelco prefab installations. The San Fernando Valley sun doesn’t just fade paint; it bakes the galvanized steel on chimney chase tops until the seams open up. Water gets in, rust spreads to the firebox, and the whole assembly starts failing from the top down. We replace chase covers before the damage hits the unit itself.
- Creosote buildup from heavy winter use after long idle periods. Short, chilly Van Nuys winter nights mean fires get lit every evening for a few weeks, then the season ends. That stop-start pattern creates layered creosote that a once-over brushing doesn’t fully remove. We classify what stage the buildup is at and show you before we clean it.
Gelco Service in Van Nuys: What Local Conditions Mean for Your Equipment
There’s a problem we see in the older Van Nuys tracts around ZIPs 91405 and 91406 that doesn’t show up the same way in most other LA neighborhoods. During remodels, homeowners sealed off fireplaces to gain wall space or update the look, and the chimney just got drywalled over. The flue stayed connected to the roof, but nobody knows it’s there anymore. We call these ghost chimneys. What we find when we open them up is not pretty: disconnected flues from shifted framing, old bird nests that have been sitting for decades, and damper assemblies that rusted solid years ago. A standard chimney sweep that only looks at what’s visible from the firebox will miss these entirely, because there’s no firebox to look at. When we do a Level 2 inspection on a Gelco unit in these tracts, we’re checking the full venting path from firebox to cap, including the parts of the system that were hidden behind sheetrock. If you can’t see daylight through the damper, we need to talk before you light that first fire of the season.
Gelco Models & Products We Service in Van Nuys
We work on the full range of Gelco equipment still installed in Van Nuys homes. That includes the direct-vent gas fireplace DV series, the 3000 series wood-burning inserts that were incredibly popular in 1970s and 80s remodels, and the 4000 series prefabricated metal fireplaces common in original 1950s and 60s construction. We also replace Gelco universal chimney caps and multi-flue caps, which tend to be the first components to fail on any exposed metal chimney. On parts, our approach is practical: OEM Gelco dampers and caps when they’re available, quality aftermarket parts for universal items like flashing. If a Gelco unit has compromised venting or structural damage, we’ll say so plainly and recommend replacement instead of patching a unit that’s past its service life. We don’t upsell; we report what we find.

FAQs – Gelco Chimney Cleaning in Van Nuys
In most cases, yes. The damper assembly on a Gelco wood-burning insert is a separate component from the firebox, so a seized or rusted damper usually means replacing the damper itself, not the entire fireplace. We carry OEM Gelco dampers for common models and can typically complete the repair in a single visit. If the surrounding metal has also corroded, we’ll show you photos before recommending anything larger. Call (855) 382-6159 for an exact assessment.
Once a year, ideally before the first winter fire. Van Nuys’ hot, dry summer months let creosote from last season harden inside the flue, and the off-season is also when birds and rodents find their way through rusted caps and build nests. An annual inspection catches these issues while they’re still simple fixes. If you burn more than two cords of wood a season, we recommend a mid-season sweep as well, especially on older Gelco prefab units where the firebox tolerances are tighter.
We do. The 3000 series insert was installed in huge numbers in Van Nuys houses from the 1970s onward, and we also stock parts for Gelco repair in Encino, so we keep the common wear items on hand: dampers, refractory panels, and door gaskets. For less common parts, we source OEM Gelco components directly from our supplier network, and we’ll give you a clear lead time before we order. The 3000 series is a durable unit, but its dampers and door seals are the weak points after 30 or 40 years of service.
Yes, and this is one of the most important inspections we do in Van Nuys. In the older tracts around 91405 and 91406, we regularly find fireplaces that were sealed behind drywall during remodels, leaving a ghost chimney the current owner doesn’t know about. The flue is still connected to the roof, and it still needs to vent whatever moisture and gases find their way up. We open the wall or use the roof access to camera the full flue path, check for disconnected sections, and report what we find. If the unit is gone but the flue remains, we’ll advise you on capping it properly. Call (855) 382-6159 to schedule a Level 2 inspection.
A genuine Gelco cap is sized and tensioned to fit Gelco flue terminations exactly, which means the spark arrestor screen sits flush and the fasteners align with the flue pipe. A generic cap often has a wider screw pattern or a mismatched screen gauge, and in Van Nuys’ bird-heavy off-season, a loose screen is an open door for nesting. The intense Valley sun also corrodes cheap galvanized caps faster than the factory coating on a Gelco cap. If we can source the correct Gelco cap, we use it; if a quality aftermarket equivalent fits correctly, we’ll install that instead and tell you why. Either way, the seal is what matters.
