Ashby Chimney Los Angeles is led by Nathan Corliss and has swept chimneys across the LA basin since 2002. Most people don’t think about their chimney until something goes wrong. That’s the whole point of an annual sweep: you catch the creosote buildup, the cracked flue liner, and the hidden blockages before they become a chimney fire or a carbon monoxide problem. This page covers what an annual sweep includes, what it costs in Los Angeles, and how our full Chimney Cleaning & Sweep in Los Angeles service works when it’s time to book.

When You Need an Annual Sweep

If you’re burning wood, creosote is forming. There’s no way around it. In Los Angeles, our mild winters mean people often think they can skip a year or two. But creosote doesn’t care how often you burn. It cares what you burn and how hot. Here are the situations where an annual sweep is non-negotiable:

• You burn wood more than twice a month. Every fire deposits creosote on your flue walls. In older hillside homes in the Hollywood Hills and Silver Lake, chimneys often run shorter than they should, which means smoke cools faster and creosote builds quicker. A once-a-year sweep is the minimum.
• You bought a house and you don’t know when the chimney was last cleaned. We see this constantly in Los Feliz and Hancock Park, where beautiful old fireplaces come with decades of unknown history. If the previous owner can’t produce a dated sweep certificate, book a sweep before the first fire.
• You can smell smoke in the house even when the fire is out. That means the chimney isn’t drafting properly. Could be creosote buildup, a broken damper, or a blocked flue. All three get found and resolved during an annual sweep.
• You hear birds or animals in the chimney. In neighborhoods like Sherman Oaks, Studio City, and throughout the Valley, nesting season comes hard. Squirrels, chimney swifts, and even raccoons love an uncapped flue. An annual sweep clears the nesting debris and lets us install a proper cap.
• It’s been more than 12 months since the last sweep. That’s the simple rule. Once a year, every year. It’s what the National Fire Protection Association (NFPA 211) recommends, and it’s what every reputable chimney company in Los Angeles follows.
• You’re burning those manufactured logs or “firelogs.” People think those don’t create creosote. They’re wrong. Manufactured logs burn differently than cordwood and can produce a different kind of residue that’s harder to remove. If you burn them regularly, your annual sweep is doing more work than you realize.

Our Annual Sweep Process

When you book an annual sweep with Ashby Chimney Los Angeles, here’s exactly what happens. Nathan Corliss and our technicians have done this thousands of times across Los Angeles, and we follow the same steps on every job. No shortcuts, no surprises.

1. Protection first. Before we touch anything, we lay down canvas drop cloths from your front door to the fireplace. Your floors, rugs, and furniture stay covered. Then we lay a protective mat across the hearth and firebox.
2. Inspect the firebox and damper. We check the damper opens and closes properly, look for cracks in the firebrick, and look at the smoke shelf and throat of the chimney. Any visible problems get flagged and written down.
3. Full flue sweep. We use a rotary sweeping system, sized to fit your flue liner whether it’s clay tile or stainless steel. The brush cleans from top to bottom, knocking creosote, soot, and animal debris loose so it falls into the firebox where our vacuum captures it.
4. Vacuum and clean the firebox. A HEPA-filtered vacuum runs the whole time, so nothing enters your living space. Once the sweep is done, we clean the firebox, smoke shelf, and damper thoroughly.
5. Report what we found. We photograph what we see. If there’s creosote buildup at Stage 2 or Stage 3, we tell you. If your flue liner has cracks or gaps, we tell you. If everything looks good, we tell you that too, and we’ll write it down.
6. Written guarantee and close-up. You get the written report and our written guarantee on any repair we complete. If we swept and found nothing wrong, you’re good for the season. If we found something, you’ll have a written price for the fix before we do anything.

Our team follows what we call the Kingswell Way: say the price, show up in the window, leave it cleaner, put the guarantee in writing, and come back if it fails. It’s the standard every Ashby location is independently owned and operated under.

Annual Sweep Pricing in Los Angeles

Here’s the honest breakdown of what an annual sweep costs in Los Angeles. These are the numbers we quote on the phone, because we don’t think you should have to wait for a technician to arrive to hear a price.

Service	Typical Cost in Los Angeles	What It Includes
Standard annual sweep (single flue)	$189 – $349	Full flue sweep, firebox vacuum, damper check, visual inspection, written report
Heavy creosote removal (Stage 2 – 3)	$349 – $599	Extended rotary cleaning or chemical treatment, plus the standard sweep
Two-flue sweep (fireplace + furnace flue)	$329 – $549	Both flues swept and inspected in one visit
Chimney cap installation (if needed)	$149 – $349 installed	Standard stainless steel cap, installed same visit when possible

What changes the price: how much creosote has built up, how tall or steep your roof access is, whether you have more than one flue, and whether the flue is clay or stainless. A Spanish-style home in the West Adams district with a two-story chimney and a steep pitch will run differently from a single-story ranch in Torrance. It’s not about zip code. It’s about access and buildup.

We give you a written price before any work starts, every time. That’s not a promotion. That’s how Ashby Chimney Los Angeles has operated since 2002. The number on the invoice is the number we quoted at the door. If we find something unexpected mid-job, we stop, we show you, and we give you a new written price before continuing. No surprises at the end.

We also don’t believe the cheapest sweep is the best sweep. Some companies in Los Angeles advertise $99 sweeps and then “discover” hundreds of dollars of urgent problems once they’re on the roof. We’d rather quote you the real number upfront and do the job right the first time.

What Your Annual Sweep Actually Protects

People ask us why they need a sweep every year. The short answer: creosote is flammable, and it builds up every time you burn. A chimney fire can reach temperatures above 2,000°F. Your flue liner, whether it’s a clay tile or a stainless steel tube, can crack under that heat. And once the flue is cracked, you’re no longer venting combustion gases safely. That’s carbon monoxide risk. It’s not a scare tactic. It’s physics. We say it because we want you to know what you’re paying to prevent.

Here in Los Angeles, we also deal with something most other markets don’t: earthquake stress. The Northridge quake in 1994 damaged tens of thousands of chimneys across the Valley and the Westside, and we still find structural issues in older homes that were never properly repaired. Masonry chimneys in neighborhoods like Echo Park, Highland Park, and Pasadena carry decades of seismic stress. An annual sweep is the easiest way to get eyes on the inside of your flue and catch cracks before they turn into a fire hazard or a collapse risk.

Why Los Angeles Homeowners Choose Ashby for Annual Sweeps

You’ve got options in this city. We know that. Here’s why people keep calling us back, year after year.

Written price before we start. Always. Not “sometimes.” Not “when you ask.” Every job, every time. That’s the Kingswell Guarantee at work.

Written guarantee on every repair. If we fix something during your sweep and it fails inside the guarantee period, we come back and fix it again at no charge. That’s the 365-Day Done Right Promise, and it’s included with every repair. We put it in writing before we leave. You keep a copy.

The repair materials are real. When your flue needs a patch or a liner needs resurfacing, we use products from recognized chimney-trade suppliers like HeatShield for ceramic flue resurfacing, Olympia Chimney for stainless steel caps and liners, and Famco for dampers and caps. You’ll never see us patching a critical venting component with whatever was rolling around the back of the van.

You know who’s walking into your home. Every Ashby Chimney Los Angeles technician is background-checked and uniformed. The person you booked is the person who shows up. That matters when someone’s going to be on your roof and in your living room.

We answer the phone. No voicemail loops. No callback forms. No “we’ll get to you Monday.” A live person answers 24 hours a day, 7 days a week. That includes 2 a.m. on a holiday. If you’ve ever waited three days for a chimney company to call you back, you understand why this is a differentiator. Nathan Corliss built this company around being reachable.

What Happens If We Find Damage During Your Annual Sweep

This is the moment where most homeowners have been burned before. A company comes out for a cheap sweep, “finds” a problem, and suddenly a $129 job is $2,000. We handle it differently.

If we find damage during your sweep, here’s what happens. First, we photograph it and show you exactly what we’re seeing, either on the roof, in the firebox, or through a scope inserted into the flue. Second, we explain in plain English what it means, what could happen if it’s left unaddressed, and what your options are. Third, we give you a written price for the repair, and you decide. There’s no pressure. If you want to hold off, we document the finding, write you the recommendation, and you decide on your own timeline.

Some things we find during annual sweeps are genuinely urgent. A cracked flue liner that’s venting gases into a wall cavity is urgent. A chimney cap that’s missing entirely and allowed a bird’s nest to block the flue is urgent. Those get fixed. Other things like minor mortar touch-ups or a damper that’s getting stiff can often wait until the next sweep. We’re honest about which is which.

If we do complete a repair, it’s covered by the Kingswell Guarantee in writing. If that repair fails inside the guarantee period, we return and correct it at no charge. Not a prorated credit. Not a “we’ll see what we can do.” We come back and fix it. That’s what the 365-Day Done Right Promise means.

How Often Should You Sweep? The Los Angeles Reality

The NFPA standard says once a year, and we agree. But let’s be honest about what actually matters for Los Angeles homeowners. A lot of homes in this city have decorative fireplaces that get lit maybe four times a year, between Thanksgiving and Valentine’s Day. Others, especially in the colder canyon communities like Laurel Canyon, Beachwood Canyon, and Topanga, burn every night from November through March.

If you’re a heavy burner, once a year is the minimum, and you might need a mid-season sweep if you’re burning unseasoned wood. If you’re a light burner, you can stretch to every 18 months. But the safest rule is once every 12 months. The cost of an annual sweep is a fraction of what a chimney fire or a carbon monoxide leak will cost you, not to mention the damage to your flue liner that comes from years of neglect.

And here’s a detail most companies won’t mention: if you have a fireplace plus a furnace or water heater that vents through the same chimney, you have two flues. They both need swept, even if you never use the fireplace. The furnace flue collects soot, and over time that reduces draft efficiency and can push carbon monoxide back into your home. Most Los Angeles homes built before 1985 have this setup. We sweep both flues in one visit for the two-flue price you see above.

FAQs – Annual Sweep

How much does an annual chimney sweep cost in Los Angeles?

An annual chimney sweep in Los Angeles runs between $189 and $349 for a standard single-flue fireplace. If you have heavy creosote buildup, a second flue, or a steep roof, the price can range from $349 to $599. Every Ashby Chimney Los Angeles job gets a written price before work begins, and estimates are free. Call (213) 652-7061 and we’ll give you a real number on the phone.

Can you come today?

We do our best to accommodate same-day sweep requests, and we do emergency appointments when a chimney can’t be safely used. Our phones are answered by a live person 24/7, so call (213) 652-7061 and we’ll tell you honestly what our availability looks like. No waiting until Monday to hear from someone.

Is it cheaper to repair my chimney or replace it?

That depends on what we find during the sweep. Small repairs like damper replacement or a chimney cap installation often cost between $149 and $349. Flue resurfacing with HeatShield typically runs less than a full liner replacement. But if your masonry chimney has structural cracks from earthquake stress, the honest answer might be a rebuild, not a patch. We’ll show you the damage, explain the options, and give you a written price for each path. You’ll never be pushed toward the more expensive option.

Do I really need an annual sweep if I rarely use my fireplace?

Yes, but not for the reason you think. Even a rarely used fireplace can accumulate creosote from the occasional fire, and more importantly, it can accumulate nesting debris from birds and rodents during the long periods of disuse. In many Los Angeles neighborhoods, we find chimneys that are completely blocked by animal nests when no one used the fireplace for a year or two. The annual sweep clears that out. And if your furnace vents through the same chimney, that flue needs sweeping even if the fireplace stays cold. For an exact recommendation based on your home, call (213) 652-7061.

How long does the average annual sweep take?

A standard annual sweep takes between 45 and 90 minutes from drop cloths to final report. If we’re sweeping two flues, removing heavy creosote, or performing a repair, plan for up to two hours. We give you a realistic window when you book, and we show up in that window.
