Gelco Chimney Cleaning in North Hollywood, CA | Corona Chimney Sweep
We’re an independent Gelco service provider handling chimney cleaning, inspection, and repair across North Hollywood, including the 91611, 91612, 91615, and 91616 ZIP codes. Here’s what makes our Gelco work different in this specific part of the Valley: most North Hollywood homes with Gelco units were built between the 1920s and 1950s, and the 1994 Northridge earthquake left a lot of those original masonry flues with hairline cracks that get discovered during what starts as a routine cleaning. We’re Gelco sales & service specialists who actually repair what we find, not a crew that cleans and hands you a referral slip. Call (855) 382-6159 if your Gelco fireplace has been sitting idle and you want to know what’s actually going on up there.
Why North Hollywood Residents Choose Us for Gelco Service
Gelco prefab fireplaces and gas log sets were installed in thousands of North Hollywood homes during the 1980s and 1990s building boom, and many of those original units are still running today. We’ve serviced Gelco equipment across the San Fernando Valley long enough to know which components fail first, which parts are worth sourcing as OEM, and when an aftermarket replacement is actually the better call, including plenty of Gelco in Universal City. Nolan Ferris, our owner, has spent well over a decade inspecting and cleaning flues across Southern California, and he’s built our shop around one principle: show the homeowner exactly what the camera sees. If your Gelco damper is rusted shut or your prefab cap is packed with nesting debris, we show you the photos. No guesswork, no scare tactics, just documentation you can keep.
Our independent status matters. We’re not a manufacturer-authorized dealer, which means we’re not obligated to push full replacements when a $45 damper rebuild or a $120 cap swap solves the problem. We source OEM Gelco parts when they’re still on the market, and we tell you plainly when an aftermarket part will outlast what the factory originally shipped. That’s the kind of straight answer North Hollywood homeowners call us back for.

Common Gelco Chimney Cleaning Problems We Solve in North Hollywood
- Caps packed with pigeon and squirrel nesting debris. The long, dry off-season in North Hollywood means uncapped Gelco prefab flues sit empty for months, which is exactly when pigeons and squirrels move in. We pull caps on nearly every spring call and find twigs, droppings, and feathers blocking the draft. A clogged spark arrestor causes smoke rollout into the living room and, in gas units, can push carbon monoxide back into the house.
- Original Gelco dampers seized from disuse and temperature swings. San Fernando Valley summers get hot, winters get cold, and metal moves with every swing. Gelco dampers from the 1980s and 1990s rust at the pivot points and freeze in whatever position they were last left. If yours is stuck open, you’re paying to air-condition the neighborhood year-round. We rebuild or replace these regularly.
- Clay-tile flues behind Gelco inserts cracked from seismic settling. This is the Northridge legacy. Pre-1950s homes in the NoHo arts district and older residential blocks took structural hits in 1994, and the masonry chimneys often developed hairline cracks that nobody noticed. Behind a Gelco insert, those cracks leak carbon monoxide into wall cavities. A Level 2 camera inspection is the only way to find them before they find you.
- Gelco stainless caps corroding at the welds. North Hollywood’s dry-crack cycles and the grit carried by Santa Ana winds wear on stainless cap welds in ways humid climates never see. Rain rarely rinses these screens, so abrasive dust just sits there and works the metal. We’ve replaced dozens of caps where the weld points failed while the rest of the cap looked fine.
- Firebox rust-through from long-term moisture and disuse. Gelco prefab fireboxes are built tough, but thirty or forty years of occasional use and Valley temperature swings take a toll. Rust at the firebox seams is a structural issue, not a cosmetic one. When we find it, we show you the photos and give you an honest repair-vs-replace call, because that’s what an independent shop can do.
Gelco Service in North Hollywood: What Local Conditions Mean for Your Equipment
North Hollywood’s original 1920s-50s brick chimneys were built for look and light use, not for the heavy wood-burning loads and seismic reality of today. The Spanish Colonial Revival homes off Magnolia Boulevard and throughout the older NoHo blocks have fireplaces that were mostly decorative features in their original floor plans, which means the flues were never designed for modern insert retrofits or decades of thermal cycling. The 1994 Northridge earthquake compounded the problem by leaving thousands of these masonry stacks with hairline cracks and separated flue tiles that owners don’t discover until a camera inspection. When someone in one of those homes calls us about a Gelco insert that’s been unused for years, we don’t expect a heavy creosote sweep. We expect cracked clay tile at the smoke shelf, a frozen damper, and a cap that’s doing nothing to keep birds out. That’s the real work in North Hollywood, and it’s why we lead with Level 2 inspections and cap and damper retrofits rather than assuming every call is just a cleaning.
We saw a perfect example on a 1940s Spanish Colonial Revival off Magnolia Boulevard in the NoHo arts district. The call started as “something is living in my chimney.” We pulled a cracked Gelco multi-flue cap that was packed solid with pigeon nesting material and twigs. The camera showed a hairline crack in the clay tile at the smoke shelf, likely from Northridge-era settling, so we installed a new stainless Gelco cap with a spark arrestor and replaced the frozen damper before recommending a liner retrofit for the following season. The homeowner had owned the house for six years and had never once used the fireplace. That’s North Hollywood in a nutshell.
Gelco Models & Products We Service in North Hollywood
We service the full range of Gelco equipment found in North Hollywood homes, including prefabricated metal fireplaces from the 1980s and 1990s builder era, Gelco gas log sets, Gelco fireplace inserts, and Gelco multi-flue caps. Our parts approach is straightforward: we source OEM Gelco caps, dampers, and firebox components when the factory still makes them, and we switch to quality aftermarket equivalents when a part is obsolete, always telling you which we’re using and why. For faster turnaround on North Hollywood jobs—and for our Gelco in Burbank customers nearby—we keep common Gelco cap sizes, damper rebuild kits, and spark arrestors stocked locally, so most repairs don’t wait on a parts order from out of state. If your Gelco firebox is cracked or rusted through, we’ll show you the photos and give you an honest repair-vs-replace recommendation rather than pushing a rebuild you don’t need.

AfterGelco Service Pricing in North Hollywood
Gelco chimney cleaning in North Hollywood typically runs between $180 and $340, depending on the condition of the unit, whether caps need removal, and how much nesting debris has accumulated. A Level 2 camera inspection, which we recommend for any pre-1994 Gelco installation, generally costs between $250 and $500 and is worth every dollar in a neighborhood with this much seismic history. Cap replacement runs $150 to $350, and damper repair or replacement lands between $175 and $400. Every estimate is free and includes a written scope of work before we touch anything. Call (855) 382-6159 if you want exact numbers for your Gelco unit, including if you need Gelco service in Valley Glen, because guessing at chimney costs without looking at the flue is how you end up surprised.

FAQs – Gelco Chimney Cleaning in North Hollywood
Expect a thorough inspection before any cleaning happens. We start with a visual check of the cap, crown, and firebox, then run a camera through the flue to look for the hairline cracks and separated tiles that are common in pre-1950s North Hollywood masonry after the 1994 Northridge earthquake. If the flue is sound, we clean it. If we find damage, we show you the photos and give you a repair scope. Call (855) 382-6159 to schedule, and we’ll walk you through what your specific unit needs.
That’s birds or squirrels nesting in the flue during North Hollywood’s long dry off-season. Gelco prefab chimneys with missing or damaged caps are particularly inviting because the metal housing stays warm and the flue sits empty for months. Pigeons are the usual culprits in the older NoHo blocks. We remove the nesting material, inspect for damage, and install a proper Gelco cap with a spark arrestor so the next spring stays quiet.
Yes. A cracked cap lets water into the flue, which accelerates rust on the damper and firebox components below it. It also lets birds, squirrels, and roof rats in. In North Hollywood’s dry climate, the bigger long-term issue is wind-driven grit working against the cracked metal and widening the failure. Replacing a cap is a $150 to $350 job, which is far cheaper than the damage an ignored crack eventually causes. Call (855) 382-6159 and we’ll give you an exact quote for your Gelco model.
In most cases, yes. We rebuild or replace seized Gelco dampers, especially the 1980s and 1990s units that froze from years of temperature swings and disuse. If the damper is rusted shut and you haven’t used the fireplace, that’s actually better news than a damper that rusted open, because the closed position kept conditioned air in your house. Either way, we can get it working again or replace it with a properly sized aftermarket damper.
Every inspection and cleaning comes with a written report and photos. For North Hollywood home sales, where buyers and insurers want proof that a pre-1994 chimney isn’t hiding Northridge-era damage, we provide Level 2 inspection documentation that holds up. If you’re selling a house with a Gelco insert, call (855) 382-6159 before listing and we’ll get you the paperwork you need.
