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 Los Alamitos, CA | Corona Chimney Sweep
We service Gelco fireplace inserts and gas log sets throughout Los Alamitos, including both 90720 and 90721. What sets our Gelco work here apart is simple: this city’s flues sit idle for months at a time, which means the problems we find are rarely creosote. They’re nests, soot blown back by Santa Ana winds, and seals that dried out while the fireplace sat unused. Call us at (855) 382-6159 and we’ll get your Gelco unit running clean before you need it.
Why Los Alamitos Residents Choose Us for Gelco Service
Most chimney companies in Los Alamitos can sweep a flue. Fewer know what to do when a Gelco insert’s flue collar seal has cracked from years of coastal moisture and idle summers. Gelco sales & service work runs deeper than brushing. We’ve spent years pulling these units apart in coastal Orange County homes, so we know how a 1962 clay tile flue behaves when someone retrofits a modern gas insert into it.
Nolan Ferris, our owner, learned combustion systems through Norco College’s vocational program before narrowing his focus entirely to chimneys. He’s spent over a decade inspecting flues across the region, and he’s methodical about classifying exactly what he finds. Not just brushing and billing. We repair what we find, and we don’t push a replacement insert when a collar seal, damper, or cap will safely fix the problem.

Common Gelco Chimney Cleaning Problems We Solve in Los Alamitos
Here’s what actually shows up on service calls across Los Alamitos, Los Alamitos service area wide:
- Cracked flue collar seals. Gelco inserts sit unused through most Los Alamitos winters. The seal between the insert’s flue collar and the chimney dries out, then cracks. When you finally light the insert, exhaust and soot seep back into the living space instead of drafting upward.
- Seized dampers and venting hardware. Coastal moisture collects in idle flues. Over months of disuse, damper assemblies and venting components corrode until they won’t open or close properly. We free them up or replace the hardware with Gelco-compatible parts.
- Soot and debris piled atop the firebox. Post-Santa Ana wind downdrafts push soot and loose debris back down uncapped flues. It settles on top of the Gelco insert’s firebox and gets blown into the room the moment the blower kicks on.
- Cracked 1950s-60s clay tile liners around the insert collar. Los Alamitos homes were built in the 1950s and 60s with clay tile flues that were never sized or supported for a retrofit insert. We regularly find hairline cracks at the collar connection point in these older flues.
- Wildlife nests in uncapped chimneys. More on this below, but it’s the most common call we get in the spring. Birds and squirrels treat unused Los Alamitos flues as prime real estate.
Gelco Service in Los Alamitos: What Local Conditions Mean for Your Equipment
Los Alamitos is a small, tightly-knit city where most homes were built in the 1950s and 1960s, many with original masonry fireplaces that see little use during the mild winters. The coastal climate means fireplaces get lit only a handful of times per year, so creosote buildup is rarely the issue. What builds up instead is everything that settles into a flue while it sits: leaves, moisture, soot from past fires, and animals looking for shelter.
The most distinctive pattern we see in Los Alamitos, and one we don’t see at the same rate in built-up Long Beach blocks, is tied to the San Gabriel River bike path and the adjacent wetlands. Homes that back onto those green corridors have uncapped chimneys that draw birds and squirrels at a rate you wouldn’t believe until you see it. In a 1960s ranch near the river path, our tech pulled a full squirrel nest out of an uncapped flue sitting above a Gelco gas insert, then found the insert’s collar seal cracked and soot blowing back into the room on downdraft days. We cleared the flue, resealed the collar, and installed a custom cap, and the homeowner could finally run the insert without soot settling on the mantel. That’s the Los Alamitos chimney problem in one job: idle flue, opportunistic wildlife, dried-out Gelco seals.
Gelco Models & Products We Service in Los Alamitos
We work on the full range of Gelco equipment installed in Los Alamitos homes: direct-vent gas fireplace inserts, vented gas log sets, inserts with standard flue collars, and gas fireplace conversions from original wood-burning fireboxes. Across all of these, we use Gelco-compatible OEM parts where they’re still available, and quality aftermarket equivalents when the OEM part has been discontinued. We stock common collar seals, damper components, and venting hardware locally, which means most Los Alamitos Gelco repairs don’t wait on a parts shipment from the distributor. Where the flue itself has deteriorated, we can also install a DuraFlex stainless flexible liner or apply HeatShield resurfacing to qualifying chimneys, restoring function without tearing out the original masonry.

FAQs – Gelco Chimney Cleaning in Los Alamitos
Why does soot blow into my Los Alamitos living room when my Gelco insert is running?
Soot blowing into the room means exhaust isn’t drafting properly through the flue. In Los Alamitos, we most often trace this to a cracked flue collar seal at the insert connection, or a blockage like a bird nest sitting above the insert. Both are repairable. Call (855) 382-6159 and we’ll camera the flue and show you exactly what’s causing it.
My Gelco gas insert hasn’t run in a few years. Does it still need servicing?
Yes, and in Los Alamitos especially so. Idle inserts collect moisture in the flue, which corrodes dampers and venting hardware. Seals dry and crack. Animals move in. We recommend a cleaning and inspection before the first fire of the season, even if the unit hasn’t been lit in years. That’s when problems have had time to develop.
Birds keep getting into my chimney near the river path. Will a cap fix it?
A properly fitted chimney cap will stop birds and squirrels from entering, yes. We install custom-sized caps that match your flue dimensions and won’t interfere with draft. Homes backing onto the San Gabriel River bike path and wetlands are the ones we see with repeat nest problems, and a cap solves it permanently.
Can you clean and inspect the flue around my Gelco insert without pulling it?
In most cases, yes. We use a camera system that goes up through the flue from the firebox, so we can inspect and clean around the insert without removing it. There are exceptions, particularly on older Los Alamitos homes where the install didn’t leave proper access clearance, but we’ll tell you upfront if pulling the insert is necessary.
My 1950s Los Alamitos fireplace has cracked clay tiles. Is that a safety problem with a Gelco insert?
Cracked clay tiles in the original flue can allow heat and combustion gases to reach surrounding framing, which is a fire hazard. With a Gelco insert, cracked tiles at the collar connection also let exhaust leak back into the living space. It’s not a problem to ignore. We assess the full liner condition with a camera and recommend repair, resurfacing, or replacement based on what we actually find. Call (855) 382-6159 for an inspection.
