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.

AfterHeatShield Chimney Cleaning in Seattle, CA | Flint Chimney Sweep
We provide independent HeatShield chimney cleaning and resurfacing service throughout Seattle, and here’s the short version: HeatShield’s ceramic coating only bonds correctly when the flue is genuinely clean and dry, which is why Seattle’s damp clay tile flues need more prep work here than they would inland. Our crew has worked on hundreds of pre-1950 Seattle chimneys, and we know exactly what HeatShield needs to hold. If you’re looking for a straight answer on whether your flue can be resurfaced or needs a stainless liner, call (830) 251-4560 and we’ll tell you what we’d do and what it costs.
Why Seattle Residents Choose Us for HeatShield Service
Hank Delano, our owner, learned chimney work through the building maintenance and construction technology program at Los Angeles Trade-Technical College, then spent years on job sites before starting Flint Chimney Sweep. He’s the kind of inspector who will hand you the camera screen and walk you through what’s actually inside your flue. That matters with HeatShield, because the product is only as good as the surface it’s applied to. We’re an independent chimney service, not a HeatShield dealer, so we specify the product when it fits the flue geometry, and we tell you plainly when it doesn’t. Every HeatShield job in Seattle gets a written price before we touch anything, and every repair carries our 365-Day Done Right Promise in writing for a full year.
Common HeatShield Chimney Cleaning Problems We Solve in Seattle
These are the conditions we see most often in Seattle chimneys, especially in homes built before 1950:
- Open clay tile joints behind glazed creosote. Seattle’s older bungalows and Capitol Hill four-squares were built with 8×8 and 8×12 clay tile flues. Decades of wood burning leave a glossy creosote layer that hides open mortar joints, and HeatShield Cerfractory won’t bond to that surface until we sweep and chemically treat the flue first.
- Efflorescence and spalling tile from marine air. Seattle’s wet winters push moisture into single-wythe brick chimneys. The original clay tiles shed flakes and mineral deposits that undermine HeatShield adhesion, so we dry the flue thoroughly and score the tile before applying coating.
- Delaminating HeatShield from a poorly prepped surface. We’ve seen flues where a previous contractor applied Cerfractory over a glazed or heavily creosoted flue without proper mechanical scoring. It flakes off in sheets. The fix is removing the failed coating, prepping the tile correctly, and reapplying in two passes.
- Crown and flashing leaks saturating a HeatShield-restored flue. Seattle rain gets in through cracked crowns and failed flashing, then cycles the restored surface through wet-dry expansion. We repair the crown, replace flashing, and often install a stainless multi-flue cap so the top of the chimney stops feeding water into the flue.
- Undersized flues on high-efficiency inserts. Many Seattle homes from the 1940s through 1960s were framed around wood stoves and oil furnaces. When a modern insert goes in, the old flue is often too small or heavily glazed. HeatShield resurfacing can restore the surface, but we’ll tell you if the flue diameter itself is the real problem before recommending a coating.
HeatShield Service in Seattle: What Local Conditions Mean for Your Equipment
Seattle’s 1940s-to-1960s bungalows and Capitol Hill four-squares were commonly built with single-wythe brick chimneys and 8×8 or 8×12 clay tile flues sized for wood stoves and oil furnaces, not for the high-efficiency inserts people run today. That single-wythe construction means there’s no air gap between the flue and the outer brick, so moisture that gets past the crown or flashing moves directly into the tile liner. In a Seattle winter, that tile absorbs water, freezes, and sheds tiny fragments into the flue. When we apply HeatShield Cerfractory over that surface, we score the tile mechanically, dry it with forced air, and then build the coating in two passes. The undersized flue issue is just as common: an insert that was fine on paper gets connected to an 8×8 flue that’s really an 8×7 after decades of creosote and debris. HeatShield restores the surface, but it can’t change the flue diameter. That’s why we camera every flue before quoting HeatShield work in Seattle, and why our recommendations come with photos you can see for yourself. Tell me what you’re seeing, I’ll tell you what it means.
HeatShield Models & Products We Service in Seattle
We work with the full HeatShield product line and stock Cerfractory Flue Sealant for standard resurfacing jobs, CeCure Sleeve for flues with structural tile loss, 316L stainless liner systems for wood and gas appliances, and HeatShield top plates and crown-mount terminations. The materials are authentic, because the ceramic chemistry and cure times are what make a resurfaced liner hold up under Seattle’s moisture cycles. We also service DuraFlex and Gelco liners. If your chimney has a different brand, we’ll tell you what’s compatible and what isn’t. For background on the product line, see our HeatShield sales & service page.
HeatShield Service Pricing in Seattle
A standard chimney sweep in Seattle typically runs $189 to $329, and a Level 2 camera inspection adds $150 to $350 depending on flue height and access. HeatShield Cerfractory resurfacing starts around $2,800 and rises with flue length, surface prep, and the number of passes needed. A CeCure sleeve or 316L stainless liner runs higher, and we’ll quote that honestly when resurfacing isn’t the right move. Your written estimate includes everything: prep work, material, application, and any crown or cap work we recommend. We never start a Seattle HeatShield job without that number in writing and approved. For an exact quote, call (830) 251-4560 and we’ll schedule a camera inspection first.

FAQs – HeatShield Chimney Cleaning in Seattle
Yes, and that’s the exact flue size we resurface most often in Seattle. The tile needs to be structurally intact and the surface properly scored after creosote removal. If the tile has collapsed or shifted, HeatShield won’t fix that, and we’ll quote a stainless liner instead. Call (830) 251-4560 and we’ll camera the flue before recommending anything.
Because the coating bonds to the existing tile surface, and you need to know what’s actually behind the creosote before putting material over it. A Chimney Inspection in Seattle shows us open joints, spalled tile, and any structural movement. In Seattle’s older single-wythe chimneys, that inspection is the difference between a resurfacing that lasts and one that delaminates in two seasons.
Rain doesn’t touch the resurfaced liner directly if the crown and cap are sound, but Seattle’s rain does saturate brick from the outside when the crown cracks or flashing fails. That water cycles the flue through wet-dry expansion and can hairline-crack a new HeatShield surface. We fix the top of the chimney before or during every Seattle resurfacing job, and we include that in the written price.
No, you can’t. Stage 3 creosote is a hard, tar-like glaze that seals the tile surface and prevents the ceramic coating from bonding. In Seattle, we see stage 3 glazing regularly from years of damp wood burning in unlined or underperforming flues. The flue gets swept, chemically treated, and mechanically scored before any HeatShield goes on. Skipping that step is how coatings end up flaking off.
Yes, we do. We install and maintain DuraFlex and Gelco stainless liner systems alongside HeatShield products, and we’ll specify the one that fits your flue geometry and appliance. If you’re in Seattle and not sure what’s in your chimney, call (830) 251-4560 and Hank or a technician will camera it and show you.
