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 Commerce, CA | Santa Ana Chimney Sweep
We provide independent Gelco chimney cleaning and repair across Commerce, CA. What makes our work here different is simple: we know how 60-year-old Gelco installs fail when they sit dormant for years under a layer of diesel grit from the 5 and 710 corridors. If your Gelco fireplace has barely been lit in a decade, that doesn’t make it clean. Call (855) 341-9658 for a free estimate.

Why Commerce Residents Choose Us for Gelco Service
Gelco fireplaces in Commerce tend to live in compact stucco tract homes built fast in the 1950s and 60s, with the original masonry flue or a mid-century insert retrofitted into it. Those units need more than a standard sweep. They need a tech who recognizes a Gelco damper that’s corroded in place, a chase cap that’s backed off its mounts, or a clay tile flue that separated years ago above an insert. Allen Becerra, our owner, spent years pulling apart and rebuilding exactly these systems across southeast LA County. He’s the person you’ll talk to when we explain what’s actually going on in your flue, not a scripted sales rep.
We work on Gelco equipment because we know these units by part, not by logo. And as an independent chimney service, we have no incentive to sell you anything the chimney doesn’t need. If a part is repairable, we say so. If it’s done, we tell you that, too. That’s the whole point of hiring someone who fixes things rather than just sweeps and leaves.

Common Gelco Chimney Cleaning Problems We Solve in Commerce
Here’s what we actually find in Commerce Gelco systems:
- Years-old glazed creosote from dormant fireplaces. Commerce residents burn a few fires a season at most. The creosote left behind doesn’t wash itself out. It hardens and glazes, especially when long dry spells bake it. Owners assume their chimney is clean because the fireplace was barely used. It isn’t.
- Gelco caps and screens fouled with bonded freeway grit. Fine brake and diesel dust from the 5 and 710 settles on rooftops and bonds with creosote and soot on Gelco spark arrestor screens. This composite doesn’t brush off. We often remove caps that are packed solid with the stuff.
- Backed-off cap mounts and torn screens on low-pitch roofs. Commerce homes have flat-to-low-pitch roofs, which makes top-side access the standard approach and also makes cap fasteners the first point of failure. Wind, sun, and grit loosen mounts over the years. Then winter rain finds the gap and follows it into the flue.
- Gelco inserts sitting in original single-flue clay tile without a modern liner. Many Commerce homes had inserts dropped into their original 1950s clay-tile flues. Those tiles crack and separate over time. The liner gap above the insert only shows on camera, and it’s a combustion gas path we take seriously.
- Bird and rodent nests packed into flues. The rail yards east of Commerce and the industrial lots throughout the city give birds and rodents plenty of harbor. A dormant flue with a failed cap screen becomes a nesting cavity fast. We’ve pulled starling nests out of Gelco flues that had been sitting for years.
Gelco Service in Commerce: What Local Conditions Mean for Your Equipment
Commerce sits in the LA Basin alongside one of the busiest freight corridors in the country. The rail yards and the 5/710 truck routes lay a permanent film of fine diesel and brake dust over every rooftop in the city. For a Gelco chimney cap, that film mingles with creosote and soot every time you burn, then bakes into a hard, bonded layer during the long dry season. What we pull out of Commerce flues isn’t clean wood creosote. It’s a soot-grit composite that judges “clean” very differently than in a purely residential suburb. A homeowner off South Eastern Avenue might look at their cap and think it’s just dirty. We look at it and know the screen is already compromised. That’s the difference local experience makes.
Gelco Models & Products We Service in Commerce
We service the Gelco systems most common in Commerce: factory-built (prefab) wood-burning fireplaces with chase-style venting, gas log lighter and gas-log insert sets, inserts retrofitted into original masonry fireboxes, and multi-flue or termination caps on masonry and chase chimneys. We use OEM Gelco parts when they’re available and correct for the unit. When the original part is a known weak point or the OEM catalog has closed, we specify quality aftermarket caps, dampers, and screens we’ve actually installed and stand behind. A cheaper cap that fails in two years costs more than one good cap. We stock common Gelco-compatible caps and screens locally for faster Commerce turnaround.

AfterGelco Service Pricing in Commerce
Chimney sweeping for a Gelco fireplace in Commerce typically runs $180 to $340, depending on the volume of creosote, the condition of the cap and screen, and whether nests or grit have hardened inside the flue. If your flue hasn’t been scoped in years, a Level 2 inspection adds camera work we use to check liner and tile condition above inserts. Cap replacement ranges from $150 to $450 depending on the cap size and material. If a clay-tile liner has separated, we’ll quote the reline options including Gelco sales & service scope and HeatShield resurfacing where it’s applicable. Every quote starts with a free on-site visit. Call (855) 341-9658 and we’ll put eyes on your exact setup.

FAQs – Gelco Chimney Cleaning in Commerce
Yes. The creosote from those few burns has been sitting in your flue hardening and glazing through every Commerce heat wave since. Add any bird or rodent activity that got in through a failed cap screen, and you have a flue that’s anything but clean. We’ll show you the camera footage. Call (855) 341-9658 to schedule a sweep or inspection.
Because Commerce sits next to the 5 and 710 corridors and the rail yards, and that fine diesel-and-brake-dust grit bonds into creosote on your cap screen in a way you don’t get in a residential-only suburb. It’s not your fire-building technique. It’s the air around your house. We clean and replace Gelco caps here constantly for exactly this reason.
Yes. We scope the original clay-tile flue above the insert and check for separated or cracked tiles. This is one of the most common failing points we find in Commerce homes, because so many inserts were dropped into original single-flue masonry without a modern liner. If the tiles are salvageable, we clean and repoint. If they’re not, we quote a liner or resurfacing option.
No. We’re an independent chimney service, not a Gelco-authorized dealer or manufacturer representative. That independence is exactly what lets us give you an honest repair-versus-replace recommendation. We source Gelco parts when they’re available and properly matched, and we’re not tied to pushing any particular product line.
It does. We access most Gelco chimneys on Commerce tract homes from the top, working carefully on low-pitch roofs where cap fasteners are often already compromised. That same roof structure is why we pay close attention to flashing and mount points when we replace a cap or screen. Call (855) 341-9658 and we’ll figure out the right approach for your roof before we quote the job.
