Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterCreosote Removal in Los Angeles, CA
Creosote removal in Los Angeles typically costs between $250 and $600 for a standard fireplace, depending on how much buildup has accumulated and whether you have a wood stove or insert that needs extra attention. Most jobs take one to two hours, and you can usually get same-week service. If you’re seeing thick, shiny black deposits inside your flue or you’ve noticed a campfire smell even when the fireplace isn’t in use, call Ashby Chimney Los Angeles at (213) 652-7061 for a written quote before any work begins.
Creosote is the byproduct of burning wood: smoke cools as it rises through your chimney, and the unburned particles condense on the flue walls. Left alone, it builds up in stages, from flaky soot to a hard, tar-like glaze that can ignite. Our full Chimney Cleaning & Sweep in Los Angeles service includes creosote removal, but plenty of Los Angeles homeowners call us specifically because their last sweep left the hard stuff behind, or because an inspection flagged dangerous buildup.
We’ve been doing this since 2002, and we don’t rush it. Creosote removal is the part of chimney work that actually keeps your house from catching fire, so we treat it that way.
When You Need Creosote Removal
Some signs are obvious. Others aren’t. Here’s what Los Angeles homeowners call us about most often:
- A strong campfire or asphalt smell near the fireplace – even when the damper is closed and no fire has burned in weeks. That smell usually means moisture has mixed with creosote inside the flue.
- Visible black, tar-like buildup you can reach – if you run a finger along the wall above the damper and come away with sticky black residue, that’s Stage 3 creosote, and it’s a fire hazard.
- Smoke backing up into the room – creosote narrows the flue opening, so the draft weakens. In older Los Angeles hillside homes with tall chimneys, this is especially common when cool marine air presses down against the flue.
- You burn a lot of oak or eucalyptus – both burn hot, but unseasoned wood, which is common after wet winters in places like Los Feliz and Topanga, produces far more creosote per fire than properly dried cordwood.
- It’s been more than a year since the last sweep – the National Fire Protection Association recommends an annual chimney inspection regardless of how little you burn, and creosote removal is part of that standard of care.
- You just bought the home and don’t know the chimney’s history – we see this all the time in neighborhoods like Eagle Rock and Highland Park, where 1920s and 1930s chimneys have decades of layered deposits nobody ever addressed.
Our Creosote Removal Process
We show up with a written plan and a straight answer on price. Here’s what happens on the day of the job:
- We inspect the flue before we touch anything. A quick camera check tells us whether we’re dealing with soft soot, granular Stage 2 creosote, or hard Stage 3 glaze. The approach changes, and so does the price, so we want the facts first. This is the Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails.
- We lay down drop cloths and run a HEPA-filtered vacuum. Creosote dust is messy and toxic, and we don’t let it drift into the living room or up into the house. Every Ashby technician arrives in uniform and has passed a background check, so you know who’s in your home.
- We clean the flue with rotary brushes sized to the liner rather than a one-size-fits-all whip. Los Angeles chimneys range widely: unlined brick in a 1910 bungalow in Pasadena, clay tile in a mid-century Silver Lake house, or stainless steel liners in newer construction. Each liner type needs a different bristle and a different touch, especially if you have a DuraFlex stainless liner that shouldn’t be scratched.
- For Stage 3 glaze, we apply a creosote treatment and return for a second pass. Hard glaze doesn’t come out with a brush alone. We use professional-grade products appropriate for your liner type, then schedule the follow-up removal once the creosote has weakened. No extra charge for the return visit if it falls inside the service window.
- We remove everything we pulled out, not just what fell into the firebox. That includes the creosote that lands on the smoke shelf and in the cap area. When we leave, you get a written report of what we found and what we removed.
- We put it in writing. Every job gets a written guarantee under the 365-Day Done Right Promise. If the creosote removal isn’t done right, or a related repair we completed fails inside the guarantee period, we come back and make it right at no charge.
Creosote Removal Pricing in Los Angeles
Here’s a straight answer. Most creosote removal jobs in Los Angeles fall into these ranges, and we give you a written price at the door before any work starts:
- Standard fireplace, light to moderate creosote: $250 – $400 – includes flue brushing, firebox cleanup, and cap inspection.
- Heavy buildup or Stage 3 glaze, standard fireplace: $400 – $600 – includes creosote treatment and a follow-up removal pass.
- Wood stove or insert, any stage: $300 – $550 – stoves have smaller flues and tighter clearances, so the work takes longer and requires more disassembly.
- Two-story chimney with roof access on a steep pitch: add $75 – $150 – common in areas like Beachwood Canyon and Mount Washington, where ladders and roof anchors are required.
What moves the price? The stage of creosote is the biggest factor: soft soot brushes out quickly, and hard glaze doesn’t. Chimney height matters, roof pitch matters (we charge more for safety equipment on steep roofs), and access matters – if we can’t get a truck close to the house or the chimney is tucked behind a parapet, it takes longer. If you’re not sure where your chimney falls, call (213) 652-7061 and we’ll talk through what you’re seeing. The estimate is free, and the price we quote is the price you’ll pay.
Can You Remove Creosote Yourself?
Honestly, no, not safely. You can sweep loose soot from the lower part of your firebox, but the deposits that matter are the ones in the flue itself, and you can’t see or reach those without opening the system. Professional rotary brushes dislodge what a wire brush can’t, and a camera inspection after the fact tells us whether the creosote is actually gone or just redistributed. More important: creosote on a hot flue wall is the cause of most chimney fires, and the moment you’re using a chemical treatment, you need to understand liner compatibility. We’d rather have you call and get it handled than read about a chimney fire in Silver Lake the week after a DIY attempt.
FAQs – Creosote Removal
How much does creosote removal cost in Los Angeles?
Creosote removal in Los Angeles costs between $250 and $600 for most residential fireplaces, depending on creosote stage, chimney height, and roof access. Stage 3 glaze costs more than light soot because it requires a treatment pass plus a follow-up removal. Call (213) 652-7061 for an exact quote – estimates are free, and we put a written price in your hand before any work begins.
Can you remove creosote the same day?
Most light and moderate creosote can be removed the same day, though we usually can’t guarantee same-day scheduling since crews are often booked earlier in the day. Same-week is consistently realistic. If you’re smelling creosote right now, call us and we’ll tell you the soonest honest window, not a fake promise.
Is creosote removal covered by homeowners insurance?
Creosote removal is considered routine maintenance and is generally not covered by insurance. Where coverage does apply is after a chimney fire: many Los Angeles homeowners policies pay for post-fire inspection and repair once you’ve filed a claim. We can’t advise you on your policy, but we can provide the written documentation your adjuster will ask for.
Does a chimney sweep include creosote removal?
A proper chimney sweep includes creosote removal, but not every sweep removes the hard glaze that builds on flue walls. That’s why we inspect first: if you’ve got Stage 3 creosote, the sweep alone won’t get it out. We’ll tell you what you have and what it takes, before we charge you anything.
How long does creosote removal take?
A standard one-story fireplace takes one to two hours from setup to cleanup. A two-story chimney with roof access or heavy glaze that needs a second pass can take two to three hours. We give you a real arrival window when you book, and we show up inside it.
Why Los Angeles Homeowners Call Ashby for Creosote Removal
Most of the calls we get about creosote are from people who already had a sweep done and were told everything was clean, then opened the damper later and saw black tar still coating the flue. That shouldn’t happen, and with us, it doesn’t. We show you the before and after, we give you a written price before starting, and we back the whole job with the 365-Day Done Right Promise.
We work with chimney-trade materials and equipment designed for the job, not whatever happens to be in the van. Liners get treated with care, whether that means working around a HeatShield resurfacing or matching our brushes to a Gelco or Olympia Chimney system already in place. Nathan Corliss, the owner at Ashby Chimney Los Angeles, signs the guarantee himself. That’s the Kingswell Way, and it’s why we put all five values in writing: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails.
Ashby carries ash right in the name. Fitting for the people whose job is to clean it out. If you’re ready to get the creosote handled before your next fire, call us at (213) 652-7061. A live person answers 24/7, not a voicemail loop, and we’ll set you up with a free estimate and a real arrival window.
