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.
Fast, Reliable Chimney Sweep Across Kenmore
A chimney sweep in Kenmore typically costs between $179 and $279 for a standard fireplace or wood stove cleaning, before any repairs. Most jobs take 60 to 90 minutes, and we can usually schedule within the same week. If your chimney hasn’t been cleaned in over a year, or you’re burning wood from a damp pile, call (336) 863-3889 to get on the calendar before the burning season really sets in.
We serve every corner of Kenmore, from the hillside streets above Arrowhead to the flats along the Sammamish River. Our crews know this city’s housing stock: postwar ranches with original brick chimneys, split-levels with clay-tile flues, and more wood stoves than most King County suburbs realize. When we roll into your neighborhood, we already know what your chimney is up against. Local expertise isn’t a slogan when the ground fog settles in every October and hangs around until mid-April.

And you’ll never open the door to a stranger you weren’t expecting.
Every Alcott technician passes a background check and identity verification before ever stepping foot on a Kenmore property. This is the Threshold Standard, and it’s not an optional upgrade. When you book a sweep, we send you the technician’s name and photo before the visit. At the door, they’ll show you a photo ID badge. Every time, no exceptions. If you’re home alone with young kids, or you’re an older homeowner who wants certainty about who’s walking up the driveway, that’s a real difference, not a talking point.
Kenmore residents call us because they want a chimney service that shows its work. Written price before any work starts. Written guarantee on every repair. If a repair fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s what Ruben built the company on.
Chimney Sweep Services in Kenmore
Chimney Sweep Services in Kenmore cover more than brushing soot out of a flue. A proper sweep means removing the creosote, that tar-like buildup that causes chimney fires, from the smoke chamber, damper, and firebox, not just the flue run. Then we do a visual check of the liner, crown, and mortar joints. In a Kenmore house built between 1950 and 1975, we almost always find something worth flagging. That’s the point: the sweep is your annual early-warning system.
A standard sweep on a wood-burning fireplace or stove runs $179 to $279 in Kenmore. If you have heavy third-degree creosote glazing, which we see regularly on lower-elevation streets, expect to add $80 to $150. We’ll show you the buildup on camera before touching it. You deserve to see what we see.
Creosote Removal and Soot Removal
Creosote forms when wood smoke cools too quickly in a damp flue. In Kenmore, with its fog-bound low basin, we see heavier deposits than in drier inland suburbs. First-degree creosote is brushable, a standard sweep handles it. Third-degree is a hardened glaze that only rotary whips and chemical treatments break down. Soot is the looser black powder, messy but less dangerous. Both come out in the same visit.

Level 1 and Level 2 Inspections
A Level 1 inspection happens during every sweep. It covers the accessible parts of the chimney: flue interior, damper, firebox, crown, cap. A Level 2 inspection goes deeper, using a video camera to look inside the flue for cracked clay tiles, eroded mortar, and hidden gaps. It’s what we recommend for any Kenmore home past its 50th year, or before your first fire after buying a house. You’ll get a photo report you can actually read.

Chimney Cleaning in Kenmore
Chimney Cleaning in Kenmore means removing what the Pacific Northwest burning season leaves behind. Starting in October and running through April, fireplaces and wood stoves in this city run constantly. The problem is what goes into them. Kenmore’s damp air makes firewood storage a challenge. An uncovered pile in the backyard soaks up ground fog from Lake Washington and the Sammamish River corridor. Moisture content lands in the 25 to 35 percent range. Burning that wood creates thick, sticky creosote fast.
For a wood stove used as a primary heat source, meaning most days of the week from October through April, sweep every 6 to 8 months, not once a year. For an occasional fireplace used a few times a month, an annual sweep still works. We’ll give you a straight recommendation based on your burn rate and wood storage setup, not a cookie-cutter calendar.
Annual Sweep and Fireplace Cleaning
An annual sweep keeps the flue clear and lets us catch small problems before they become liner replacements. Fireplace cleaning is more than the flue: we clean the firebox, damper, glass doors, and grate, and vacuum the ash dump. For gas fireplaces, the cleaning schedule stretches, but the glass and log set still need attention every few years to keep the burn clean and the viewing glass clear.
Trusted Brands We Service in Kenmore
We install and service the brands chimney professionals actually specify. That includes DuraFlex stainless steel liner systems, which we stock in the sizes Kenmore homes most often need, and Gelco water repellents and crown sealants, which matter more here than almost anywhere else in King County. We also work with Copperfield caps and Olympia Chimney components. Stocking local parts means we don’t leave a Kenmore job half-done waiting on a warehouse three states away. If your existing liner or cap was installed by another company, we service those systems just the same.
Common Chimney Sweep Problems We See in Kenmore Homes
- Third-degree creosote glazing. Kenmore’s damp firewood, stored in uncovered piles, produces stage-2 and third-degree buildup faster than drier inland suburbs. A standard brush won’t touch it, you need rotary tools and a technician who knows when to stop drilling and start recommending burning-practice changes.
- Moisture weeping at the firebox throat. In lower-elevation neighborhoods along the Sammamish River floodplain, ground fog and high water table conditions push moisture into aging masonry. Even in August, we find chimneys weeping at the firebox, a sign the crown and waterproofing were never addressed.
- Cracked clay tiles in 50 to 70 year old flues. Kenmore’s postwar ranches and split-levels still run original clay-tile liners. Decades of moisture cycling have cracked and spalled many of those tiles. A Level 1 sweep alone won’t catch it, which is why a Level 2 inspection is the only honest recommendation for these homes.
- Moss and lichen on crowns and shoulders. The persistent fog in Kenmore’s low basin feeds aggressive moss growth that holds water against masonry. It looks like a cosmetic issue, but it’s slowly breaking down the crown and letting water into the stack year-round.
Pricing for Chimney Sweep in Kenmore, WA
A standard chimney sweep in Kenmore runs $179 to $279 for a fireplace or wood stove. A Level 2 inspection adds $150 to $250, and we recommend it for any home built before 1980, or before the first fire after a purchase. If we find third-degree creosote, removal runs $80 to $150 extra. Waterproofing and crown repair depend on the masonry’s condition, but on lower-elevation streets near the river, budget $300 to $600 for that work. You’ll get a written price before we start, every time. Call (336) 863-3889 for a free estimate.

FAQs About Chimney Sweep in Kenmore
A wood stove used as a primary heat source in Kenmore should be swept every 6 to 8 months, because damp local firewood produces creosote much faster than seasoned wood in a drier climate. An occasional fireplace, burned a few times a month, can usually go a full year between sweeps. The real variable is your wood, if it’s been sitting uncovered in the fog, you’re on the shorter schedule. Call (336) 863-3889 and we’ll give you an honest interval based on how you actually burn.
That staining is groundwater and ground fog wicking through aging masonry, a signature condition of Kenmore’s low basin between Lake Washington and the Sammamish River. The water table stays high under lower-elevation streets, and moisture moves up through the brick by capillary action. Waterproofing and crown repair stop it from getting worse. If you’re seeing stains in August, it’s time for an inspection, call us at (336) 863-3889.
First-degree creosote is a soft, flaky soot that brushes out during a standard sweep. Third-degree is a hard, shiny glaze that forms when damp wood smoke condenses on a cold flue wall, which happens constantly in Kenmore’s fog-heavy burning season. It requires rotary tools and chemical treatments to remove, and it’s far more likely to ignite. If you’re burning local unseasoned wood, you’re building third-degree creosote every week. A sweep now costs less than a chimney fire later.
Yes, almost always. Homes from that era run original clay-tile liners that have endured 50 to 70 years of Pacific Northwest moisture cycling. Cracked tiles, spalled mortar, and eroded crown joints hide where a brush can’t reach. We recommend a Level 2 camera inspection on every Kenmore ranch built before 1980, because skipping it means the first sign of trouble is often smoke in the house or water down the chimney. The written report shows you exactly what’s happening inside.
A standard sweep in Kenmore ranges from $179 to $279. Heavy creosote removal adds $80 to $150, a Level 2 inspection adds $150 to $250, and waterproofing or crown repair on moisture-damaged masonry can add $300 to $600 depending on chimney height and access. What drives the price up in Kenmore specifically: low-elevation moisture damage, damp firewood habits, and 50-year-old liners that need a real look, not just a brush.
