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.

Seattle’s damp, seven-month heating season puts real strain on chimneys, and most of the damage happens quietly. The flue needs attention even when the fire burns low and lazy. We live here.

Why Alcott Chimney Sweep Is Seattle’s Preferred Chimney Sweep Company
Every technician who pulls up to a Seattle home is background-checked, identity-verified, uniformed, and announced to you by name and photo before the visit. That’s the Threshold Standard, and it’s not an optional upgrade. When we ring the bell, you’ll recognize the person at the door because you’ve already seen their face and their ID badge is out when we arrive.
Seattle homeowners tell us the same thing again and again: they’ve let a chimney go too long because they didn’t want a stranger in the house. We solve that. Our Threshold Verified process means the technician’s photo and name reach you before we do, and a live person answers our phones around the clock. If something smells like smoke at 11 p.m. in Seattle, you get a human being, not a voicemail.

Chimney Cleaning in Seattle
Chimney Cleaning in Seattle means removing the creosote and soot that build up faster here than nearly anywhere else on the West Coast. Most Seattle homes need a sweep every year, and a standard cleaning typically runs $189 to $349 depending on flue condition and access. We recommend an annual sweep in the fall, right before the rainy season pushes you indoors.
What We Remove
Creosote is the tar-like residue left behind by wood smoke. In Seattle, we see two kinds: flaky first-degree creosote that brushes off, and glazed third-degree creosote that hardens into a shiny, crusted layer. Glazed creosote is the most flammable kind and it often hides in the firebox and smoke chamber, where hand-brushing won’t touch it.
Soot is the lighter, powdery carbon left by gas and wood fires. Even a gas fireplace can leave soot in the flue over time. We use professional-grade tools and never box-store substitutes.
After the Sweep
You get a full visual check of the firebox, damper, and accessible flue. If we find something more serious, like spalled brick or a cracked liner, we’ll show you photos before recommending anything. Nothing gets recommended without camera evidence you can see for yourself, and we’ll tell you plainly when work can safely wait.
Fireplace Cleaning in Seattle
Fireplace Cleaning in Seattle goes beyond the flue itself and down into the firebox, grate, ash dump, and the visible masonry around the hearth. A full fireplace cleaning typically runs $139 to $229 and keeps the whole system running efficiently through the wet winter months. A clean firebox burns hotter, which helps the flue draft better and keeps the living room warmer.
Firebox and Hearth
Ash and ember buildup in the firebox can trap moisture against the back wall, and in Seattle’s marine humidity that means rust, spalling, and cracked refractory panels. We vacuum out the ash, clean the grate, check the refractory panels, and inspect the firebrick for damage before anything fails in January.
Glass Doors and Damper
Glass doors cloud up from soot and creosote vapor. We clean the glass, inspect the gaskets, and check the damper’s seal. A damper that doesn’t close all the way lets conditioned air escape up the flue all year, and in Seattle’s long heating season that adds up on your utility bill.
Trusted Brands We Service in Seattle
We carry and install the same professional trade brands Seattle’s chimney specialists specify: DuraFlex liner systems, Olympia Chimney caps, and Famco vents and dampers. We stock common replacement parts for Seattle homes, so we’re not waiting a week on a shipment from across the country to fix a corroded cap or a worn damper. When a galvanised cap fails on a Ballard chimney, we replace it with stainless steel and we do it the same week. Our Chimney Sweep team knows these products well enough to recommend the right part for Puget Sound conditions, not just the cheapest one on the shelf.
Common Chimney Sweep Problems We See in Seattle Homes
- Corroded galvanised caps and flashing. Salt air and persistent marine humidity eat galvanised steel fast. We see caps go soft and flashing pull away from the roofline within a decade, letting water into the crown and masonry before anyone notices. Stainless components last far longer here.
- Glazed third-degree creosote from low-temperature smoldering fires. Seattle’s mild wet winters encourage fires that burn low and slow, which lays down a hardened creosote layer that hand-brushing cannot remove. It sits in the firebox and smoke chamber, and it’s a chimney fire waiting for the right conditions.
- Cracked clay-tile liners in Craftsman bungalows. Ballard, Capitol Hill, Fremont, and Beacon Hill are dense with 1900-to-1940 homes whose original clay-tile liners have endured a century of wet/dry cycling. Once those tiles spall, a sweep alone leaves the flue unsafe, and a DuraFlex reline becomes the repair.
- No-burn day compliance gaps. The Puget Sound Clean Air Agency issues mandatory curtailment days multiple times each winter. Homes with open masonry fireplaces or non-EPA-certified inserts face fines for burning on those days, and a damper inspection or certified insert upgrade is often the solution.

FAQs About Chimney Sweep in Seattle
Every year, and in salt-air-exposed homes near Puget Sound, we recommend a visual inspection twice a year, once before burning season and once after. Seattle’s persistent humidity keeps masonry damp for months, which accelerates spalling and liner cracking. Call (336) 863-3889 and we’ll set a schedule that fits your home’s exposure.
Because it’s almost certainly galvanised steel, and Seattle’s salt air plus marine humidity corrodes galvanised caps faster than inland markets. The fix is a stainless cap from Olympia Chimney or a similar professional brand, which costs more up front but lasts decades longer here. We can quote you before any work starts.
Glazed creosote is the hardened, shiny layer of tar-like residue that forms when smoke condenses and bakes inside the flue. Seattle’s seven-month damp season makes it worse because low-temperature smoldering fires produce it in abundance, and the chronic moisture helps it set. It cannot be removed by hand-brushing and usually requires chemical treatment or mechanical removal. Call for an inspection and we’ll show you exactly what’s inside your flue.
No. The Puget Sound Clean Air Agency enforces mandatory no-burn days, and burning in an open masonry fireplace or a non-EPA-certified insert during a curtailment is a violation that carries fines. If you’re not sure whether your fireplace qualifies, a damper inspection and a certified insert upgrade conversation are things we do as part of routine Seattle service.
Possibly. The original clay-tile liners in Seattle’s Craftsman bungalows are now a century old, and after decades of wet/dry cycling they often crack and spall. If your liner is compromised, sweeping alone leaves the flue unsafe. We’ll camera-inspect it, show you the footage, and tell you honestly whether a DuraFlex reline is needed or whether a sweep is all you need. No scare-selling, just photos and facts.
