Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterHow Much Does Chimney Cleaning Cost in Seattle?
A standard chimney sweep in Seattle typically runs $195 to $375, depending on the flue type, how much creosote has built up, and whether the technician can reach the roof safely. Add a Level 2 inspection and you’re usually looking at $325 to $600 total. If your sweep turns up cracked tile or a failed liner, repair work climbs from there, but that’s a separate conversation with its own written price before anything starts.
Most Seattle homes we visit fall in the mid-range of that estimate. The city’s damp maritime climate and the fact that so many of us burn alder, fir, and maple in older masonry fireplaces means creosote accumulates differently here than in drier parts of the country. We’ll get into why that matters for your bill in a moment.

Chimney Cleaning Cost Breakdown (2026)
Here’s what Seattle homeowners are actually paying this year. These ranges reflect real jobs across the city, from Ballard bungalows to Queen Anne foursquares to newer construction out in West Seattle.
| Service | Typical Seattle Price Range | Notes |
|---|---|---|
| Standard chimney sweep (single flue) | $195 – $375 | Includes brushing, creosote removal, and a basic visual check |
| Sweep + Level 1 inspection | $250 – $425 | Readily accessible chimney, no obstructions |

| Gas fireplace cleaning and service | $150 – $300 | Burner cleaning, log set check, vent inspection |
| Chimney cap installation | $175 – $450 | Stainless caps last longer in Seattle’s wet climate |
| Crown repair or rebuild | $400 – $1,200 | Depends on crack size and whether mortar has failed |
| Chimney liner installation | $2,200 – $5,500 | DuraFlex and Olympia Chimney systems are our standard |

| HeatShield resurfacing | $1,400 – $3,200 | Restores a damaged flue without a full reline |
What pushes you toward the higher end? Three things come up again and again in Seattle. First, heavy creosote. If you’ve been burning wet wood or your firebox has a history of smoldering fires, we may need extra time and specialized tools to get the flue clean. Second, roof access. Steep pitches are common on Capitol Hill and Madrona, and some homes need our technicians to set up additional fall protection, which adds labor time. Third, flue condition. A sweep on a healthy tile-lined flue is quick. A sweep on a flue that’s spalling, cracked, or missing tiles takes longer because we’re being careful not to dislodge anything that shouldn’t move.
What keeps you at the lower end? Easy roof access, a fireplace you use a few times a season rather than nightly, and a chimney you’ve had swept within the last two years. Annual maintenance isn’t just good practice. It’s also the cheapest version of this bill you’ll ever see.
What Affects Chimney Cleaning Pricing in Seattle
No two chimneys are the same, and Seattle’s building stock makes that especially true. Here are the factors that move your price up or down.
- Creosote level. Creosote is the tar-like buildup that causes chimney fires. Stage 1 is a light soot you can brush away. Stage 3 is a hardened, glazed deposit that requires rotary tools and significantly more time. Most Seattle homes we sweep land at Stage 1 or 2, but a house that’s gone five or six years without service can hit Stage 3 fast.
- Roof pitch and access. A gentle 4/12 pitch on a rambler in Lake City is a quick setup. A steep 10/12 on a Craftsman in Wallingford means more time rigging safety gear, which shows up in the labor line. We won’t cut corners on this one, and you shouldn’t hire anyone who will.
- Flue type and liner condition. A straight clay tile flue sweeps clean in about an hour. A flue with offsets, a stainless liner that’s been in for decades, or a prefab metal chimney all change the approach and the time required.
- Number of flues. A single-flue chimney costs less than a two-flue chimney. That seems obvious, but plenty of Seattle homes have a furnace flue and a fireplace flue side by side, and only one gets used. We’ll tell you which ones need attention.
- Time since last cleaning. Skip three years and you’re paying for the cleanup, not just the sweep. There’s a real cost difference between maintaining a clean flue and rescuing a neglected one.
- Wood type and burn habits. Alder, fir, and maple are common firewood around here. Seasoned wood burns hot and leaves less creosote. Green or damp wood does the opposite. If you’re buying firewood from a lot on Aurora Avenue, ask how long it’s been seasoned. Your flue will thank you.
- Whether you need an inspection. A basic sweep includes a visual check. A full Level 2 inspection adds a video scan and attic/crawlspace access. If you’ve just bought the house, are changing fuel types, or have had a chimney fire, you want the Level 2.
Who We Send, and Why That Matters to the Price
Every Alcott Chimney Sweep technician passes a background check and identity verification before ever stepping onto a customer’s property. This is the Threshold Standard, and it isn’t an optional upgrade. We send you the technician’s name and photo before the visit, and they’re required to show a photo ID badge at your door. That’s the Threshold Verified process, and it’s non-negotiable for us.
If opening the door to a stranger is a real concern for you, that concern is valid, and it should shape who you hire. You’ll know exactly who’s coming, and you’ll see their face before they arrive at your home. Ruben Castellano started Alcott Chimney Sweep in 2002, and the company has operated as an independently owned and operated location within the Threshold Group family of home-service companies since then. Every job includes a written price before work begins, a written guarantee on every repair, and a free return visit if that repair fails.
How to Save on Chimney Cleaning
You can’t avoid every chimney cost, but you can keep yours on the lower end of the Seattle range. These are the moves that actually work.
- Book in spring or early summer. Fall is when every chimney company in Seattle is slammed. Scheduling in May or June usually gets you a better slot and sometimes a better rate. It also means you’re not waiting three weeks for an appointment when the first cold snap hits.
- Bundle the sweep with your inspection. Doing both at once costs less than doing them separately. If you’re due for a Level 2 inspection, combining it with your annual sweep saves you the trip charge and the setup time.
- Burn seasoned wood only. Firewood that’s been dried for at least six months burns hotter and cleaner. That means less creosote, which means a faster sweep. Over a few seasons this genuinely adds up.
- Get your chimney cap installed once. A stainless steel cap keeps rain, birds, and debris out of your flue. In Seattle, where we get roughly 37 inches of rain a year, a cap is one of the best long-term investments you can make. It prevents water damage that would otherwise turn into a much bigger repair.
- Ask for a written price up front. Any chimney company that won’t give you a written number before work starts is a risk. Alcott gives every customer a written price before any work begins. No surprise charges at the end, ever.
- Don’t wait on small cracks. A hairline crack in the crown or a loose brick costs a few hundred dollars to fix now. Left alone through a few Seattle freeze-thaw cycles, it turns into a rebuild. Catching problems early is the single biggest way to save money.

What’s Included in Every Alcott Chimney Sweep Job
Pricing only means something when you know what you’re buying. Here’s what comes standard with every job, no matter the price point.
- A written price before any work begins, so you know the total before we start
- A written guarantee on every repair, included at no extra charge
- A free second visit if a repair fails within the coverage period
- The 365-Day Done Right Promise: a full year of accountability on every completed job
- Live phone coverage around the clock, answered by a person, not a voicemail system
- Professional-grade materials. We install DuraFlex liner systems, HeatShield resurfacing, Gelco, Olympia Chimney, Famco, and Copperfield products. These are the brands chimney professionals specify, not box-store substitutes.
That last point affects the price. A liner is not a commodity. The difference between a DuraFlex system and an off-brand liner shows up in fit, longevity, and how it performs through a wet Seattle winter. When we quote you a liner, you’re getting the material we’d put in our own homes.
How Does Seattle’s Climate Affect Chimney Pricing?
It affects it more than most homeowners realize. Seattle’s wet climate means chimneys here face water intrusion in a way that chimneys in drier markets don’t. Masonry absorbs moisture, and when temperatures dip below freezing, that moisture expands and cracks the masonry from the inside. We see this pattern all over the city, especially in older Ballard and Fremont homes with original brickwork.
This is why a chimney cap and a sound crown matter so much here. They’re not cosmetic. They’re the first line of defense against a repair that runs into the thousands. A $250 cap today can prevent a $1,200 crown rebuild later.
If your chimney doesn’t have a cap, or if you can see daylight through cracks in the crown, that’s worth addressing before next winter. Call (336) 863-3889 and we’ll take a look.
FAQs – Chimney Cleaning Cost
How much does a chimney sweep cost in Seattle?
A standard chimney sweep in Seattle costs $195 to $375 for most homes. If you add a Level 2 inspection, the total typically lands between $325 and $600. The exact number depends on your flue type, creosote level, and roof access. Call (336) 863-3889 for a free estimate specific to your chimney.
Is it cheaper to repair or replace a chimney liner?
Repair is almost always cheaper when the damage is limited to a small section. HeatShield resurfacing, which restores a damaged flue from the inside, runs $1,400 to $3,200 in Seattle. A full liner replacement with a DuraFlex or Olympia Chimney system runs $2,200 to $5,500. If the flue has widespread cracking or missing tiles, replacement is the right call. We’ll tell you honestly which one you need, with a written price before any work begins.
How often should I have my chimney cleaned in Seattle?
Once a year if you burn wood regularly, and at least every two years if you only use your fireplace occasionally. Seattle’s damp climate and the popularity of alder and fir firewood mean creosote builds faster here than in drier markets. If it’s been more than three years, book a sweep and expect the higher end of the price range. Call (336) 863-3889 and we’ll get you on the schedule.
Does a chimney cleaning include an inspection?
A basic sweep includes a visual check of the firebox, damper, and accessible flue sections. A full Level 2 inspection is separate and adds $100 to $250 to the job. It includes a video scan of the flue and a check of the attic, crawlspace, and chimney exterior. If you’ve just bought the home, changed fuel types, or had a chimney fire, the Level 2 is the right choice. Estimates are free, so call and we’ll help you decide.
Can you come today if my chimney smells like smoke?
In many cases, yes. Our phones are answered by a live person around the clock, so when something smells like smoke at 11 p.m., you’re talking to a human, not a voicemail. A smoke smell usually points to a draft problem, a blocked flue, or creosote buildup, and none of those should wait. Call (336) 863-3889 and we’ll figure out the fastest way to get someone out.
