Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Chinatown, CA
Chimney repair in Chinatown usually means one of two things: restoring corroded gas-appliance flues in pre-1940 brick buildings, or bringing commercial grease ducts in Hill Street and Broadway restaurant buildings up to city fire-code compliance. The housing stock here is dense, shared-wall, and mostly unlined masonry from the 1900 – 1930 era, which changes how repairs are diagnosed and priced. Pearl Chimney Cleaning has served Chinatown since 2013, and the honest version of this page is that most “chimney” work here is either fire-safety repair or restaurant exhaust work disguised as sweeping. Call (833) 630-4048 if you own one of these buildings and want a straight answer.
Why Chinatown Homes Are Different
Chinatown’s oldest buildings along Hill, Broadway, and the tong blocks were built before modern flue codes existed. A lot of the pre-1940 brick storefronts and residential units share narrow, unlined masonry chimneys that now vent both gas appliances and, in many cases, the restaurant kitchens on the ground floor. That shared-flue configuration is exactly what makes repair work here different from the rest of Los Angeles. Upstairs apartments often get stove and water-heater exhaust pushed through the same stack a dim sum or BBQ kitchen is using, which means flue liners here see grease vapor, not just combustion gases.
Mild, dry Southern California weather means wood-burning is rare, so creosote is not the main problem. The real issue is restaurant grease vapor condensing inside shared brick flues serving multiple tenants. Over a few years that residue forms a hard, flammable glaze that standard residential chimney brushes cannot remove. Technicians doing repair or cleaning work in Chinatown need rotary chain whips and an LAFD commercial hood/duct inspection mindset, not a homeowner’s fireplace brush kit. Santa Ana wind events and the basin’s trapped winter air also push grease and soot odors back down into upper units, which is how a “smell problem” in an apartment usually becomes a liner repair or a code-required commercial flue cleaning.

Our Main Chinatown Services
Homeowners in Chinatown call us most about two things: getting aging gas-appliance flues swept and getting clogged dryer vents cleared in buildings where duct runs are old, long, and shared.
Chimney Sweep in Chinatown
A proper sweep in a Chinatown building is rarely a quick brush-up-the-flue job. The unlined brick chimneys here collect years of soot from water heaters, wall furnaces, and shared stacks. Before any sweeping starts, we check the interior with a camera so you see exactly what we are dealing with. In buildings where a restaurant shares the stack, we treat the duct as a commercial grease run, not a residential flue. Flat-price quotes are agreed before we book, and the camera report is included. For the full explanation of how sweeping works in these older buildings, see Chimney Sweep in Chinatown.
Dryer Vent Cleaning in Chinatown
Dryer vents in Chinatown’s wood-frame and brick buildings tend to be long, bent, and sometimes run through shared wall cavities. That means lint builds faster and blocks airflow sooner. A clogged vent here is a fire hazard and a mold risk because the trapped moisture cannot escape. We clean the full run from dryer to exterior cap, and then we check the cap itself, since many originals in these buildings are rusted or painted shut. If you have never had your vent cleaned in a building like this, read Dryer Vent Cleaning in Chinatown for what the job involves.
Chimney Repair in Chinatown
Most Chimney Repair calls we get in Chinatown involve one of two situations: a corroded flue liner inside an unlined brick stack that is now leaking exhaust into bedrooms, or a shared flue serving multiple tenants that LAFD has flagged for immediate attention. The repair choice depends on whether the original masonry is sound enough to reline or whether a stainless liner system like DuraFlex needs to be installed. We inspect with a camera first, show you the footage, and only then recommend work. For a deeper look at the repair service itself, see Chimney Repair.
Chimney Cap Installation
Signs you need it
Rust streaks on the brick below the flue opening, water pooling in the firebox after rain, or birds nesting inside the stack are the most common signals that no cap, or a failed cap, is in place.
What it costs in Chinatown
Chimney cap installation in Chinatown normally runs $290 – $575 for a stainless cap sized to an older brick flue, with custom oversized caps for commercial openings at the higher end.
How we do it
We measure the flue opening, select a stainless cap with the right mesh to keep birds out, anchor it to the masonry crown, and seal the fasteners against rain intrusion.
Chimney Liner Installation
Signs you need it
Exhaust smells in upper rooms, visible gaps or missing bricks in the flue, and water damage around the chimney breast all suggest the original clay or brick liner has failed and is no longer containing combustion gases.
What it costs in Chinatown
Chimney liner installation in Chinatown typically runs $2,300 – $5,100 for residential gas-appliance flues, while taller or shared commercial stacks on Hill and Broadway can exceed that range depending on access and height.
How we do it
We run a camera through the flue to map the damage, measure the correct diameter, install a DuraFlex stainless liner from the appliance collar to the top, and reconnect the exhaust with a sealed termination.
Chimney Flashing Repair
Signs you need it
Water staining on ceilings near the chimney chase, damp brick below the roofline, or visible gaps in the metal flashing around the stack are clear signs the original flashing has pulled away or corroded.
What it costs in Chinatown
Chimney flashing repair in Chinatown typically falls between $375 and $850 for standard roof penetrations on 2- to 4-story buildings, with higher access costs on steep Harbor Freeway-adjacent hillside roofs.
How we do it
We remove the old flashing, inspect the roof deck beneath for hidden rot, install new step and counter-flashing with a flexible sealant appropriate for the building’s roof material, and test for leaks before finishing.
What Chimney Repair Costs in Chinatown
| Item | Typical range in Chinatown |
|---|---|
| Chimney cap installation (stainless) | $290 – $575 |
| Chimney liner installation (residential) | $2,300 – $5,100 |
| Chimney flashing repair | $375 – $850 |
Do I really need a new liner if my building’s chimney is only used for a gas water heater?
Maybe. The flue from a gas appliance moves moisture-laden exhaust, and in Chinatown’s unlined pre-1940 brick stacks that moisture has often crumbled the interior joints. We only recommend a liner when the camera footage shows actual gaps or corrosion, and you see that footage before deciding.
How often does a commercial restaurant flue in Chinatown need cleaning or repair?
Every 12 months at minimum for a busy restaurant, and often every 6 months for BBQ or high-grease kitchens. LAFD inspection failures are common when shared stacks serve multiple tenants, so schedule ahead of your permit renewal. Call (833) 630-4048 and we will time it with your inspection calendar.

What pushes prices up in Chinatown is access: upper-floor flues on Hill Street storefronts often require ladder work from a narrow alley, and shared commercial stacks mean coordinating with multiple tenants and LAFD paperwork. What you will not get is a price that changes after we start. Flat-price quotes are agreed before booking, so the number you approve is the number on the invoice.

FAQs About Chimney Company in Chinatown
We prioritize fire-code inspection failures. For commercial buildings in 90012 with an LAFD violation on a shared flue or grease duct, we can usually schedule the camera inspection within a few business days so you have documentation to show the inspector. Call (833) 630-4048 and mention the violation notice.
If the flue is shared or runs through common walls, yes. Most Chinatown buildings with multiple tenants require written approval from the building owner or HOA before we alter any shared stack. If you are a tenant, we can provide a camera report you can forward to your landlord to start the conversation.
Both. A large share of what we do in Chinatown is commercial kitchen exhaust and grease-duct cleaning inside the same shared brick stacks that vent upstairs apartments. That is simply what the building stock requires here, and we have the rotary equipment to do it safely.

What Chinatown Customers Say
"Liner was cracked in two places. He walked me through the repair options honestly, including the one that was cheaper for him and better for me."
- Marisol Salazar"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
- Rosa Martinez"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
