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 Westmont, CA | Corona Chimney Sweep
We provide independent Gelco service across Westmont, CA, and the honest truth is this: most “Gelco chimney cleaning” calls in this ZIP code aren’t about sweeping creosote at all. They’re about capping abandoned flues, replacing rusted spark arrestors, and repairing cracked crowns on chimneys that haven’t held a fire in decades. If your Westmont home has a Gelco cap or prefab stack that’s failing, call us at (855) 382-6159 and we’ll tell you what’s actually wrong before we quote a dime.
Why Westmont Residents Choose Us for Gelco Service
Westmont’s housing stock is dense blocks of 1940s and 1950s wood-frame bungalows and low stucco duplexes. The chimneys on these homes are original brick-and-mortar, most of them unlined, and a huge number were abandoned when owners converted to wall furnaces or central heat. What that means for Gelco equipment is specific: we’re usually dealing with caps and dampers that haven’t been touched since the Carter administration, rusting quietly while birds move in. Our crew knows Gelco’s double-wall prefab sections, cap assemblies, and top-sealing dampers from years of pulling them apart on South LA rooftops, including Gelco service in Inglewood and nearby areas. We’re not sweep-only. We repair what we find, and we don’t send you to someone else when a Gelco cap screen has torn out or a section joint has pulled loose.
Nolan Ferris, our owner, grew up in South Corona and cut his teeth on HVAC fundamentals and combustion systems through Norco College’s vocational program before narrowing his focus entirely to chimneys. He’s spent well over a decade inspecting and cleaning flues across the Inland Empire and South LA. The guy can look at a Gelco cap rust pattern and tell you whether it’s five years old or fifteen. That’s the level of familiarity we bring to every Westmont job. For more about our full scope of Gelco sales & service, that page covers the broader picture.

Common Gelco Chimney Cleaning Problems We Solve in Westmont
- Rusted-out cap screens letting birds into the flue. Westmont’s mature trees and telephone lines make ideal perching for pigeons and starlings. A Gelco spark arrestor screen that’s rusted through gives them an entry point straight down to the smoke shelf. We remove the nesting material, clear the flue, and install a fresh OEM or aftermarket screen that actually keeps wildlife out.
- Double-wall prefab section joints separating after Santa Ana wind flexing. The Santa Ana events that blow through South LA put real lateral stress on exposed prefab stacks. Gelco’s double-wall sections have a locking seam that can spread or lose its seal after decades of dry heat followed by wind gusts. We re-seat and seal those joints before they become a fire or water path.
- Top-sealing damper gaskets dried and cracked from the warm, dry climate. Westmont sees long dry spells and mild winters. Rubber and silicone gaskets on Gelco top-sealing dampers don’t like that. When they crack, the flue stays open to rain, debris, and whatever’s flying by. We inspect the gasket and replace the assembly when it’s past saving.
- Multi-flue cap pans corroding where roof moisture sits on a poorly pitched crown. Older Westmont crowns are cracked from decades of dry heat and occasional winter rain. Water pools, sits against the Gelco cap pan, and corrosion follows. We usually tuckpoint the crown first, then set the new cap so it drains properly instead of holding water.
- Abandoned chimneys with no cap at all. This is the big one in Westmont. A chimney that hasn’t burned since the 1980s often has no cap, or a cap that disintegrated years ago. That flue is now a birdhouse with a masonry shell. We cap it, screen it, and close the whole system to weather and wildlife.
Gelco Service in Westmont: What Local Conditions Mean for Your Equipment
Here’s the thing about Westmont that doesn’t show up on a generic chimney service page. This is an unincorporated LA County pocket where the housing stock dates to the post-war buildout. The original chimneys were true masonry, unlined, and built for wood fires that stopped being lit decades ago. Most homes converted to wall furnaces or central heat and never looked back at the fireplace. So when we get a Gelco-related call in Westmont, or even a Gelco service in View Park-Windsor Hills nearby, it’s almost never routine sweeping. It’s a homeowner who found a ceiling leak under the chimney, or heard birds in the wall, or got flagged by an insurance inspection. The chimney hasn’t burned anything in 30-plus years, but the cap is gone, the crown is cracked, and the smoke shelf is now a starling nesting site. That’s the Westmont job. If you can’t see daylight through the damper, we need to talk before you light that first fire of the season.
On a block of original wood-frame bungalows in Westmont, our tech opened a masonry flue that hadn’t seen a fire since the Reagan years and found a starling nest packed against the smoke shelf, with the old Gelco cap screen rusted through and hanging by one screw. We cleared the nest and debris, tuckpointed the cracked crown, and set a new Gelco multi-flue cap with a fresh bird screen. The homeowner’s ceiling leak stopped and the flue was finally closed to weather and wildlife. That’s a typical day here.
Gelco Models & Products We Service in Westmont
We service Gelco round and oval factory-built metal chimney sections, including double-wall insulated stacks. We install and replace Gelco chimney caps and multi-flue caps for both masonry and prefab applications. Gelco universal and top-sealing damper assemblies are a regular part of our work in Westmont, as are replacement spark arrestor and bird-screen cap inserts. When a model is still supported, we use OEM Gelco parts. When it’s discontinued, we carry quality aftermarket caps and can custom-fab a replacement that fits the existing stack correctly. We stock common Gelco cap sizes and screen assemblies locally so Westmont jobs don’t wait on a slow parts shipment from the East Coast.

AfterGelco Service Pricing in Westmont
Gelco cap and damper work in Westmont runs on a few variables: whether we’re repairing or fully replacing, what model or size the existing equipment is, and what the crown and masonry look like underneath. A standard cap replacement with a new bird screen typically starts around $180 to $340 depending on the cap size and whether it’s single or multi-flue. Tuckpointing a cracked crown adds to the total, and a full prefab stack replacement is a bigger job we’ll quote honestly after we’re on the roof and can see the damage. Every estimate is free and we show you the problem before you pay for anything. Call (855) 382-6159 and we’ll give you a real number for your Westmont chimney.

FAQs – Gelco Chimney Cleaning in Westmont
No. We’re an independent chimney service company that works on Gelco equipment. We are not authorized, sponsored, or warranty-backed by Gelco. What we have is practical field experience with their product lines and access to OEM parts where those parts still exist.
Both, and we tell you which is which. If your Gelco model is still supported, we use OEM caps, dampers, and screen assemblies. If it’s discontinued, we use quality aftermarket or custom-fab replacements. We never pass off aftermarket as OEM, and we never install a part that doesn’t fit your existing stack correctly.
Most cap replacements take 60 to 90 minutes on the roof, plus whatever masonry work the crown needs. If we’re also clearing a bird nest from the smoke shelf or tuckpointing cracks, that adds time. For an exact estimate on your Westmont home, or if you need Gelco repair in Lennox, call (855) 382-6159.
We cover Gelco round and oval double-wall prefab sections, chimney caps and multi-flue caps, universal and top-sealing dampers, and spark arrestor/bird-screen inserts. If you have an older Gelco cap that’s no longer in production, we can usually build a replacement that matches the existing flue opening.
We say it plainly, in Westmont specifically this is one of the most common calls. Usually the answer is both: tuckpoint the cracked crown so water stops pooling, then replace the corroded cap pan so it drains properly. A rebuild of the full chimney is rarely necessary on these post-war bungalows unless the masonry itself is failing. Call (855) 382-6159 for a free estimate and we’ll show you what’s actually wrong before recommending anything.
