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 Artesia, CA | Walnut Chimney
We provide independent Gelco chimney cleaning and insert service across Artesia and nearby communities, including Gelco in Cerritos, and the first thing we look at isn’t the unit itself. It’s the masonry around it. Most Gelco inserts in Artesia sit inside chimneys built during the post-war tract boom, and plenty of those crowns and brick courses have picked up earthquake damage over the decades. That’s the step generic sweep services skip, and it’s the step that determines whether your Gelco unit will ever draft the way it should.

Walnut Chimney works on Gelco sales & service equipment throughout the Gateway Cities, and we know these inserts from the firebox to the cap. If you’re in Artesia and your Gelco fireplace hasn’t been touched in years, call (855) 341-3461. We’ll tell you what’s actually going on before anyone puts a brush in the flue.
Why Artesia Residents Choose Us for Gelco Service
We’re not a Gelco dealer, and we don’t want to be. We’re an independent chimney company that services Gelco inserts and gas log sets because they’re common in Artesia’s older homes and because we know how they fail. Russ Dempsey, our owner, started his career doing fireplace retrofits and cleanouts on the ranch homes scattered through the San Gabriel Valley before focusing exclusively on chimneys, so the post-war masonry we see in Artesia is the exact housing stock he learned on. That matters when someone needs an honest read on a Gelco unit that’s been dormant for a decade.
We repair what we find, with the right material for the job. That means OEM Gelco parts for dampers and gaskets, not whatever’s on the truck. And because Artesia is a small, dense city, we can get to you quickly without spending half the day crossing county lines. One call handles the sweep, the inspection, and whatever repair the unit actually needs.

Common Gelco Chimney Cleaning Problems We Solve in Artesia
- Seized damper linkages. Artesia homeowners use their fireplaces a handful of times each year, which means dampers sit closed for months at a stretch. On Gelco inserts, the linkage that opens and closes that damper binds up over time, leaving you with a unit that won’t fully open or won’t seal tight enough to keep cold air and dust out. We free the mechanism when it’s salvageable and replace it with an OEM part when it isn’t.
- Cracked firebox refractory liners. The short, hot burn cycles typical of occasional-use fireplaces in our dry Mediterranean climate are rough on refractory panels. Gelco firebox liners crack and warp under that kind of thermal stress, and once they do, heat reaches the masonry shell behind them. We inspect those liners on every Artesia call because they fail quietly.
- Glass door gasket and seal degradation. Years of disuse in a dry climate dries out the gasket material on Gelco glass doors. When that seal goes, soot and smoke leaks past the frame instead of heading up the flue. If the glass on your Gelco insert is staining around the edges, that’s usually the culprit.
- Loose venting and cap interfaces. Artesia sits in the Gateway Cities region where seismic activity is a fact of life, and the dry Santa Ana winds push a lot of debris through older flues. We routinely find Gelco venting and cap connections that have loosened from ground movement and wind vibration. A loose cap lets rain and animals in, and it lets your draft escape.
- Chimney crowns in need of repointing before the sweep. This is the Artesia-specific one. Deteriorated mortar crowns and missing spark arrestors are standard on the 1950s and 60s chimneys here, and we can’t safely run a brush through a flue that’s shedding brick. Sometimes the masonry work comes first, then the Gelco service.
Gelco Service in Artesia: What Local Conditions Mean for Your Equipment
Here’s the thing about Artesia that doesn’t apply in most neighboring cities — even nearby La Palma Gelco service follows a different pattern — and it changes the order of operations on nearly every Gelco job we do here. In the older tracts near the 91 Freeway, it’s common to find chimneys with earthquake-damaged crowns and loose bricks that need repointing before a sweep can even be performed. That’s not dramatic language. It’s the direct legacy of the region’s seismic activity meeting masonry that’s been exposed to sixty or seventy years of dry heat, Santa Ana wind shifts, and occasional ground movement.
What that means for your Gelco insert is simple: the unit can be in perfect working order and still draft poorly because the chimney it’s attached to is compromised. A cracked crown lets water into the masonry, which weakens the mortar, which loosens the brick. A loose brick inside the flue is a draft killer and a fire hazard. We’ve learned to inspect the full system on every Artesia call to handle the chimney first, then the insert. If the flue’s clean and the draft is right, everything else takes care of itself.
Gelco Models & Products We Service in Artesia
We work on the full range of Gelco fireplace equipment you’ll find in Artesia homes: gas fireplace inserts, wood-burning inserts, glass-door and screen assemblies, and vented gas log sets. The damper linkages and firebox liners on these units are specific, and we keep common OEM replacement components on hand for faster turnaround in the 90701 and 90702 ZIP codes.
For load-bearing and sealing parts like dampers, gaskets, and firebox refractory panels, we use Gelco-sourced components. For standard caps, flashing, and masonry consumables, we’ll use quality aftermarket material where it’s the right call. We won’t put a knockoff damper in your insert to save a few dollars, and we won’t upsell you on an OEM cap when an aftermarket one does the same job.

AfterGelco Service Pricing in Artesia
What you’ll pay for Gelco chimney cleaning in Artesia depends on what we find, and we’re straightforward about the costs before any work begins. A standard sweep and Level 1 inspection runs between $200 and $300 in this market, but when a Gelco insert needs a damper linkage replaced or a crown needs repointing, the added labor and materials push the total higher. The masonry work near the 91 Freeway is often the deciding factor, since it’s common enough here that we quote it as a known variable rather than a surprise.
Every estimate is free, and we walk you through what’s needed with pictures from our camera inspection. Nothing gets recommended that you can’t see for yourself. Call (855) 341-3461 and we’ll give you an exact number for your Artesia chimney.

FAQs – Gelco Chimney Cleaning in Artesia
Sometimes. But in Artesia, a long-dormant Gelco insert usually needs more than a sweep because the chimney around it has been sitting through earthquake seasons and Santa Ana wind events while the firebox stayed cold. We’ll do whatever the inspection shows is necessary: sweep, damper service, gasket replacement, or masonry repointing. We’ll tell you plainly if a basic sweep is all you need. Call (855) 341-3461 to schedule an inspection and we’ll confirm exactly what’s warranted.
Damper linkage binding is a common Gelco issue, and in Artesia it’s often tied to how rarely the fireplace gets used. The linkage sits static for months, the dry air does its work, and the mechanism loses its range of motion. If the damper can be freed and it holds position correctly, that’s the fix. If the linkage is worn or seized, we replace it with an OEM Gelco part so it opens and seals the way it was designed to.
If your chimney has loose bricks or a cracked crown, yes, that work comes first. Running a brush through a flue that’s shedding mortar is unsafe and pointless because the masonry instability will be back the next season. In Artesia, particularly near the 91 Freeway, we see enough earthquake-damaged crowns that we inspect the structure before quoting any Gelco insert service. We’ll repoint what needs it and then do the cleaning the flue actually needs.
It depends on the extent of the damage. A hairline crack in a refractory panel can often be repaired with the right refractory material. A liner that’s spalled, warped, or crumbling is a replacement, no question. We use OEM Gelco liners where the unit is structurally intact and only the panel is compromised. If the firebox itself is compromised, we’ll tell you honestly and weigh repair against replacement rather than pushing a rebuild you may not need.
Yes, and it’s one of the most practical upgrades we recommend for Artesia’s Gelco inserts. A properly fitted cap with a spark arrestor keeps Santa Ana-driven leaves, twigs, and nesting materials out of the flue and prevents embers from exiting. We source caps from Gelco and Famco and will match the right size and venting configuration to your setup. Call (855) 341-3461 for a quote that includes both the cap and the installation.
