Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Commerce
A chimney sweep in Commerce, CA typically runs $189 – $329 for a standard fireplace with a Level 1 inspection included, and most homes here need it more than the owners realize. The post-war tract houses that fill the blocks between Eastern Avenue and the 5 freeway still hold their original 1950s brick fireplaces, and those clay flues have been accumulating creosote for seventy years. We’ve worked enough of these homes to know exactly what we’re walking into before we even back the van up to the curb. Call (855) 341-8132 and we’ll give you a straight answer on what your chimney actually needs.

Why Lantern Chimney Sweep Is Commerce’s Preferred Chimney Sweep Company
We’re not a national franchise rolling a truck through Commerce on a route. We’ve swept enough chimneys in the 90101 to recognize the specific failure patterns of this housing stock before we set foot on the roof. The east-side bungalows near Eastern Avenue, the tight-lot stuccos off Commerce Boulevard, the older frame homes downtown: each block has its own quirks, and we know them.
Our Chimney Sweep team is led by Len Castorena, who’s built the business on one simple habit: we tell you what we found, and we can fix it. Commerce homeowners call us because they want a straight diagnosis, not a fear-based pitch. That’s why so much of our work here comes from neighbors referring neighbors. When one flue in a shared stack gets swept and the other doesn’t, word gets around about who actually caught the problem.
We also show up prepared. We carry professional-grade materials from Olympia Chimney and Famco on the truck, so when we find a cracked clay tile or a missing cap on a Commerce job, we’re not scheduling a second trip for parts. One visit, the problem addressed.
Styles & brands we work with





Chimney Services in Commerce
Chimney Services in Commerce start with a full assessment of what you actually have: an original 1950s brick fireplace, a gas-converted flue, or a shared masonry stack that hasn’t been opened in decades. A routine sweep here runs $189 – $329, but the real value is the inspection that comes with it. In Commerce, we’re rarely dealing with a clean flue that just needs a brushing. We’re dealing with decades of deferred maintenance.
Level 1 and Level 2 Inspections
A Level 1 inspection is what most annual sweeps include: visual check of the accessible flue, firebox, damper, and cap. A Level 2 inspection goes further, with camera work inside the flue to check for cracked tiles, blockages, or hidden chambers, and it’s the one we recommend when you’ve just bought a Commerce home, changed fuel types, or haven’t had the chimney opened in years. On shared stacks near Eastern Avenue, we often recommend a Level 2 before anyone starts sweeping, because what’s in the adjacent flue matters.

Creosote and Soot Removal
Mild Commerce winters mean fireplaces get used only a handful of times a year, and that’s exactly when glaze creosote sneaks up on you. The fires you do burn are often quick, smoky, and low-temperature, which produces exactly the kind of sticky creosote that hardens into a third-degree glaze in the smoke chamber. We remove it mechanically and chemically, then show you what it looked like before we scraped it out.

Chimney Sweep Certified in Commerce
Chimney Sweep Certified work in Commerce means we follow the National Fire Protection Association 211 standard and document what we find. Every sweep we do in the 90101 includes a written report with photos, so you’re never taking our word for it. When we tell a homeowner off Eastern Avenue that the gas-converted chamber next to their active flue is full of old soot and bird debris, we have the camera footage to prove it.
Annual Sweeps and Fireplace Cleaning
An annual sweep in Commerce runs $189 – $279 for a typical 1950s masonry fireplace. That includes cleaning the firebox, smoke chamber, flue, and damper area, plus a Level 1 inspection. If we find a problem that needs more than a brushing, we’ll stop, show you the photos, and give you options with real prices before doing anything else.

Gas-Converted Flue Assessment
A surprising number of Commerce fireplaces were converted from wood to gas decades ago, often with the original clay flue left in place behind the gas insert. The hidden chamber behind that conversion is where we find old soot, bird nests, and sometimes a direct path for carbon monoxide back into the living space. We assess these flues as part of our standard sweep, because ignoring them is how small problems become dangerous ones.
Trusted Brands We Service in Commerce
When a Commerce chimney needs more than a sweeping, we don’t reach for whatever’s on the shelf at the hardware store. We specify and install materials from professional supply lines like Olympia Chimney, Famco, and DuraFlex. These are the brands restoration contractors trust, and they’re what we stock on the truck for fast turnaround in Commerce. If your clay flue has cracked and you need a DuraFlex liner or a HeatShield ceramic resurfacing, the parts are professional-grade and the work is done by the same crew that diagnosed it. No second company, no handoff, no excuses.

AfterCommon Chimney Sweep Problems We See in Commerce Homes
- Shared masonry stacks on the east side: Between Eastern Avenue and the 5 freeway, many 1950s homes share a single chimney with a neighbor. Sweeping one side without checking the other can push old soot and debris into the adjacent unit. We always inspect both flues before we start, even if we’re only hired for one side.
- Uncapped, gas-converted flues: Commerce has dozens of fireplaces that were converted to gas decades ago and never capped, leaving a direct opening for birds, rain, and drafts. The hidden chamber behind the conversion fills with debris, and that’s what leaks soot or CO into the living space when the neighbor burns wood.
- Spalling brick and cracked crowns on 1950s tract homes: The stucco bungalows throughout Commerce are hitting seventy years old, and their chimney crowns are often original. A cracked crown lets water channel down into the flue, which accelerates clay tile deterioration and makes shared-stack cross-contamination worse.
- Third-degree creosote from mild winters: Commerce homeowners who only burn a few fires a year often think they don’t need a sweep. That’s when glaze creosote forms in the smoke chamber, and glaze creosote is exactly the kind that fuels chimney fires. Low-use fireplaces still need annual Level 1 inspections.
Pricing for Chimney Sweep in Commerce, CA
A standard chimney sweep in Commerce runs $189 – $329, which includes a Level 1 inspection and a written report. A Level 2 camera inspection runs $249 – $449 depending on the flue configuration and how many flues are in the stack. If we find spalling brick or a cracked crown, those repairs start around $175 – $400 depending on access, and a HeatShield ceramic resurfacing for an eligible flue typically falls between $2,500 and $4,500, far less than a full tear-out and reline. Shared stacks on the east side sometimes require both flues to be inspected before we can safely sweep one, and that affects the quote. We give you the number before we touch anything. Call (855) 341-8132 for a free estimate.

FAQs About Chimney Sweep in Commerce
We can, but we won’t do it blindly. In a shared masonry stack, sweeping one flue while the adjacent flue is uncapped or full of debris can push soot, dust, and bird nesting into your neighbor’s unit or back into yours. Before we sweep your side, we run a camera through both flues to see what’s actually in that shared chamber. If the neighbor’s side is clean and capped, we proceed with your sweep. If it’s not, we’ll document what we found and tell you exactly what needs to happen before we brush anything. Call (855) 341-8132 and we’ll walk you through what we need to check.
Expect us to find more than soot. An uncapped 8×8 clay flue on a seventy-year-old Commerce home has been open to every bird, rainstorm, and Santa Ana wind event since Eisenhower was in office. We’ll typically find bird debris, spalled clay tile edges, and moisture staining in the firebox. The sweep itself is straightforward, but we’ll likely recommend a cap and possibly a camera inspection of the flue interior to check for crack damage. The sweep runs $189 – $279, and the cap installation is priced separately after we show you what we found. Call (855) 341-8132 for a full quote.
Yes, and in Commerce specifically, low-use fireplaces are often the most dangerous ones. The mild winters here mean fireplaces get lit sporadically, usually with quick, smoky fires that produce sticky creosote. That creosote never burns off, so it glazes over in the smoke chamber and becomes a third-degree fuel source. We’ve found third-degree creosote in Commerce fireplaces that the owners swore they only used twice the previous winter. An annual Level 1 inspection catches this before it becomes a chimney fire. The inspection is included with a standard sweep. Call (855) 341-8132 to schedule one.
We handle it the same way on every Commerce bungalow: from the roof, with the right equipment, and with the smoke chamber accessed through the firebox below. Steep pitches off Eastern Avenue and along Commerce Boulevard require roof brackets and a second technician, which is already factored into our pricing. The creosote gets scraped mechanically from the smoke chamber walls, then we use a chemical treatment to break down the glaze. We don’t skip the smoke chamber just because it’s awkward to reach. That’s exactly where the chimney-fire fuel collects. Call (855) 341-8132 and we’ll give you an honest read on what your flue needs.
A Level 1 inspection is visual only: the accessible portions of the flue, firebox, damper, and cap, done with no special tools and no disassembly. A Level 2 inspection uses a camera pushed through the full flue run and is what we recommend for any Commerce home that’s just been purchased, any chimney that’s been converted from wood to gas, or any shared stack where you can’t see what’s happening on the other side. In Commerce, where gas conversions and shared masonry stacks are common, we recommend a Level 2 any time the flue’s history is unknown. That runs $249 – $449 and gives us photographic proof of what’s inside. Call (855) 341-8132 to set one up.
