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 North Hills, CA | Ashwood Chimney Sweep
We provide independent Gelco fireplace and chimney cleaning across North Hills, from 91343 to 91393. What makes our Gelco work here different is simple: most North Hills homes were built in the 1950s and 60s with original clay-tile flues that have never been scoped, so our calls usually start with a camera inspection, not just a sweep. Norm Castillo and our crew know Gelco dampers, firebox panels, and cap assemblies from years of hands-on work across the north Valley, including Gelco in Northridge. Call (833) 805-3229 for a free estimate.
Why North Hills Residents Choose Us for Gelco Service
Gelco fireplaces show up all over North Hills, usually in the post-war ranch tracts off Sepulveda and Nordhoff where builders installed them by the block in the 1950s and early 1960s. Our crews work on Gelco sales & service units every week in this part of the Valley, and we’ve learned the brand’s quirks the hard way: damper assemblies that seize during the long idle season, refractory panels that spall after decades of intermittent holiday-season burns, and cap terminations that foul with Santa Ana debris. Because we’re an independent service provider, not a manufacturer-authorized shop, we give you a straight read on whether a Gelco unit needs a cleaning, a repair, or replacement. No warranty process steering, no upselling. Norm Castillo’s been working fireplaces and flues in Southern California for close to two decades, and he treats every North Hills chimney like it’s attached to a house he’d want to live in.

Common Gelco Chimney Cleaning Problems We Solve in North Hills
- Cracked clay-tile flues hidden behind stucco exteriors. Most North Hills tract homes still have their original clay flue tiles, and the Valley’s hot, dry summers followed by cold winter burns cause thermal cycling that opens hairline cracks. A top-down sweep never shows these. Our camera inspection does.
- Seized Gelco damper assemblies. Fireplaces here sit idle from roughly April through October. Dampers corrode and stick during those months, then homeowners force them open on the first cool evening and bend or snap the linkage. We free them properly or replace with aftermarket assemblies that meet OEM spec.
- Santa Ana debris packed into cap screens and spark arrestors. The winds that funnel through the north Valley push leaves, twigs, and bird nesting material down uncapped flues. We routinely clear packed Gelco cap screens that mimic a fully blocked chimney.
- Spalled refractory panels in older Gelco prefab boxes. Concentrated holiday-season burns after months of disuse cause the firebox liners in builder-grade Gelco zero-clearance units to crack and separate. We inspect every panel during the cleaning and tell you plainly if the firebox is still sound or past patching.
- Creosote glaze on original clay flues. Decades of wood fires in North Hills’ 60-plus-year-old fireplaces leave a hard, glassy creosote layer that brushes can’t remove. We use mechanical removal methods designed for this exact condition.
Gelco Service in North Hills: What Local Conditions Mean for Your Equipment
Here’s the thing about North Hills that shapes nearly every Gelco call we take here: the neighborhood was built out almost entirely as post-war single-story ranch tracts, and much of that housing was sold with decorative fireplaces that have never been scoped. On a block of identical stucco-and-red-tile ranches, the flue we open on one house is usually the same original clay-tile build as the next. That means a first-ever Level 2 camera inspection is the norm in North Hills, not a routine add-on. We’re not just sweeping creosote; we’re documenting what’s been hidden behind the damper since Eisenhower was president. When a homeowner on a tract street off Plummer in 91343 calls about a Gelco fireplace that hasn’t been lit in years, we expect to find what we usually find: a seized damper, hardened creosote, maybe a bird nest above the smoke shelf, and tile cracks that a standard sweep would’ve missed. This is the local reality of Gelco service in North Hills, and it’s why we lead with the camera.
Gelco Models & Products We Service in North Hills
We service the Gelco product lines most common in North Hills tract housing: factory-built zero-clearance wood-burning fireplaces from the 1970s through 1990s builder-grade installs, gas-log and gas insert sets, and Gelco fireplace inserts with glass doors. We also handle Gelco chimney caps and multi-flue cap assemblies. When a part needs replacing, we stock quality aftermarket dampers, cap assemblies, and refractory panels that meet or exceed the original Gelco spec, and we use OEM-equivalent parts where fit matters. If your Gelco firebox shell or flue collar is sound, we repair. If the refractory is cracked through or the firebox has lost integrity, we tell you directly rather than patching it and sending you down the road.

AfterGelco Service Pricing in North Hills
A Gelco chimney cleaning in North Hills typically runs between $180 and $340, depending on what the flue holds and whether the damper needs freeing or the cap needs clearing. Level 2 camera inspections start around $150 and run to about $400 when we’re documenting first-ever scopes or suspected wind-driven damage. Cap installations on Gelco flues generally range from $100 to $450 depending on the termination and whether we’re fitting a screened spark arrestor. What drives the cost is simple: 60-plus-year-old clay flues with decades of creosote glaze take longer than a modern stainless liner, and Santa Ana debris clear-outs add labor. Every estimate is free and we walk you through what we found on camera before any work begins. Call (833) 805-3229 and we’ll give you a straight number for your specific Gelco unit.

FAQs – Gelco Chimney Cleaning in North Hills
No. Gelco doesn’t require manufacturer authorization for routine cleaning, inspection, or repair work, and we’re an independent service provider rather than a factory-authorized shop. What matters is that the crew understands Gelco damper assemblies, firebox panels, and cap terminations, and ours does from years of hands-on work in North Hills and Gelco in San Fernando.
In North Hills, that’s usually a wind-driven debris blockage or a seized damper stuck partly closed, not creosote buildup. Santa Ana winds push leaves and nesting material down uncapped clay flues, and the long idle season lets dampers corrode into a half-open position. We’ll run a camera to see exactly what’s blocking the flue and clear or repair it accordingly. Call (833) 805-3229 if you’re getting smoke back into the room.
Almost never. Gelco damper assemblies seize from disuse, especially after North Hills’ hot, dry summers, and the linkage often bends or snaps when forced. We free and adjust the damper, or replace the assembly with an aftermarket unit that meets OEM spec. The fireplace itself is usually fine. We’ll tell you if it isn’t.
Yes. If a wind event packed your Gelco cap screen or pushed debris past an uncapped flue, we clear the chimney first, then fit a capped, screened termination sized for your Gelco flue. We stock cap assemblies that match the original spec, and this prevents the next Santa Ana from refilling the flue. Call (833) 805-3229 and we’ll get you on the schedule.
Yes. What you see from the hearth tells you nothing about the flue above the smoke shelf. In North Hills, where original clay-tile flues run 60-plus years old and have never been scoped, the only way to know if the tile is cracked or the cap is packed with wind debris is a camera inspection. We’ve found bird nests and hairline tile cracks in fireplaces that looked spotless from the living room. It’s worth the look.
