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.

AfterDuraFlex Chimney Cleaning in Seattle, CA | Alcott Chimney Sweep
We provide independent Chimney Sweep in Seattle and DuraFlex inspection across the city, from Ballard to Beacon Hill, and one thing shapes our DuraFlex work here more than anything else: the city’s burn-curtailment rules push people toward short, smoldering fires that glaze creosote onto liners faster than a hot burn would. Ruben Castellano and our Seattle crew have pulled, swept, and re-sealed hundreds of DuraFlex systems in this city’s old masonry chimneys. Call (336) 863-3889 to book a sweep or get a straight answer about your liner. We’re not affiliated with DuraFlex, but we know how their liners behave in Seattle’s damp, mild climate better than most.
Why Seattle Residents Choose Us for DuraFlex Service
We’ve been servicing chimneys since 2002, and in that time we’ve installed enough DuraFlex sales & service work to know which liner models hold up in a city where masonry stays damp from October through May. DuraFlex Pro, the double-wall insulated liner, handles Seattle’s low-temperature flue conditions better than single-wall SS in older homes, and we recommend accordingly. Our technicians arrive with names and photos sent to you in advance, a photo ID badge at the door, and a written price before any work starts. That’s our Threshold Standard. Ruben Castellano grew up in a house with a creosote problem nobody caught until it mattered, and he built this company around the idea that a homeowner should know exactly who’s coming and what they’ll find before the truck pulls up.
Common DuraFlex Chimney Cleaning Problems We Solve in Seattle
- Saturated insulated wrap from crown cracks. Seattle’s 150-plus rainy days mean a small crack in the chimney crown turns into a wet mess around a DuraFlex Pro liner. The wrap soaks through, loses its insulating value, and creosote starts building on the inside face of the liner. We see this constantly in Fremont and Capitol Hill chimneys that have gone a few wet seasons without a Level 2 inspection.
- Pinholes in DuraFlex AL on gas appliances. The aluminum liner we install for gas fireplaces and inserts develops pitting when mild acidic condensate sits against the metal. Seattle’s marine humidity keeps that moisture from drying out, so the pinholes spread. If water’s dripping into your firebox, this is likely the culprit.
- Crushed or dented DuraFlex SS through offset flues. Ballard and Beacon Hill Craftsman homes often have original clay-tile flues with offsets and corbeled sections. A single-wall SS liner negotiating that path can dent or crush during installation, reducing the effective cross-section and killing your draft. We pull top plates off and find this all the time.
- Failed top-plate seals letting water down the annulus. The gap between the DuraFlex liner and the old clay tile becomes a water channel when the top plate or cap seal fails. Seattle’s persistent drizzle makes this a slow, steady drip that rots the liner from the outside in. A cracked crown above the liner makes it worse.
- Rapid glazed creosote buildup on short, smoldering burns. When the Puget Sound Clean Air Agency calls a no-burn day, Seattle homeowners who can still burn often load up on allowed days with short, low fires. That’s the exact pattern that produces stage-three glazed creosote, and it sticks to a DuraFlex liner just as readily as to clay tile. Sweeping it off before it reaches a quarter-inch is critical.
DuraFlex Service in Seattle: What Local Conditions Mean for Your Equipment
The Puget Sound Clean Air Agency issues mandatory wood-burning curtailment days multiple times each winter across the Seattle metro. Homeowners with open masonry fireplaces or non-certified inserts risk fines for burning on those days. What that does to DuraFlex-lined fireplaces is specific and measurable: on days when burning is allowed, people compensate with shorter, cooler fires, which deposit creosote on the liner’s interior wall instead of burning it off. It’s not laziness. It’s the regulatory environment. A DuraFlex liner in Seattle can accumulate a glaze layer in two seasons that might take five years to form in a drier, colder city where people run hot, steady fires all winter. When you add the marine humidity keeping the exterior of the liner damp from October through May, you get a system that fails from both sides: creosote glazing inside, moisture intrusion outside. We tell Seattle DuraFlex owners to expect cleaning more often than the national average, and to get a camera inspection of the liner and crown every two years rather than waiting for a draft problem.
DuraFlex Models & Products We Service in Seattle
Our crew works on the full DuraFlex residential line: DuraFlex Pro, the double-wall pre-insulated stainless liner we most often recommend for Seattle’s older masonry flues; DuraFlex SS, the single-wall flexible stainless option; DuraFlex AL for gas appliances; and DuraFlex Insulated Wrap kits for masonry relining jobs. We keep genuine DuraFlex top plates, caps, and connectors stocked for the models we install most, so a Seattle service call doesn’t get held up waiting on parts from a distributor. When OEM components are available, we use them, because the fitting tolerances on flexible systems leave little room for substitution. For consumables like clamps and fasteners, we use quality aftermarket parts where they don’t affect liner integrity. If you need an inspection before cleaning, we can camera the entire liner and show you what we’re seeing, then hand you a written price for whatever the repair requires.
DuraFlex Service Pricing in Seattle
A standard DuraFlex chimney sweep in Seattle typically runs $189 to $279 for an open masonry fireplace with an accessible roof, before any repairs. If we’re also doing a Level 2 camera inspection of the liner, expect to add $150 to $250 depending on the height and access. Top plate or cap replacement around an existing DuraFlex liner usually lands between $275 and $450 installed. A full crown repair above the liner runs $800 to $1,400 depending on the size and condition. What drives the cost in Seattle is roof pitch, chimney height, and whether the liner has been neglected long enough to require re-sealing rather than cleaning. Every quote is written, itemized, and delivered before we touch anything. Call (336) 863-3889 and we’ll get a technician out to look at your specific setup. The estimate costs nothing.

FAQs – DuraFlex Chimney Cleaning in Seattle
Yes. Seattle’s burn-curtailment rules create more frequent smoldering fires, which produce glazed creosote faster. Most Seattle DuraFlex owners should schedule a sweep every year instead of every two. If you burn mostly on curtailment-free days with low, smoldering fires, call us at (336) 863-3889 and we can camera the liner to check the accumulation.
Yes, with a Chimney Inspection - Seattle using Level 2 camera standards. We run a video camera down the entire liner from the top, checking for pitting, crushing, wrap saturation, and creosote glaze thickness. It’s the same standard we’d use on any relined chimney, and it gives us the evidence to tell you clean, repair, or replace.
On no-burn days, you can’t legally burn wood in an open fireplace or non-certified insert. What many Seattle households do instead is burn more on allowed days, often with short, damp, smoldering loads. That’s a creosote factory for any liner, DuraFlex included. We can help you decide whether a certified insert upgrade makes sense so you burn less often and cleaner when allowed.
The most likely cause is pinhole corrosion in the aluminum liner, created by acidic condensate from the gas appliance and accelerated by Seattle’s dampness. A cracked crown or failed top plate can also let water run down the outside of the liner and into the firebox. Call (336) 863-3889 and we can camera the liner to pinpoint the leak before recommending a repair or full re-line.
Often the crown can be repaired or replaced independently of the liner. The liner only needs replacing if water intrusion has already saturated the insulation wrap, started corrosion, or crushed the liner body. We’ll inspect and tell you plainly what’s salvageable and what isn’t. The estimate is free, and the recommendation comes with photos.
