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.

AfterFast, Reliable Chimney Cap & Crown Across Bothell
Chimney cap and crown work in Bothell usually runs $450-$1,800 depending on whether you need a simple replacement cap, a custom multi-flue cap, or a full crown rebuild with coating. Most jobs are completed in a single visit, and every one starts with a camera-scan inspection so you can see exactly what needs work before you spend a dollar. That matters here more than in most cities, because Bothell’s wet valley climate and aging prefab fireplaces create failure patterns that don’t show up in a quick visual check. If you’re off North Creek Parkway or over in the Canyon Park area, call (980) 580-8641 and we’ll have a technician out to assess your cap and crown in a single visit.
Our Chimney Cap & Crown team has worked on hundreds of Bothell homes, from 1980s tract houses near Thrasher’s Corner to mid-century builds along the Sammamish River. The thing about chimney caps in this city is that the fog does as much damage as the rain. We see rusted chase covers on factory-built fireplaces that look fine from the ground but are quietly letting water pour into the firebox. For homeowners anywhere in Bothell, that means the real work starts with a camera, not a ladder and a flashlight.
Why Emberly Chimney Cleaners Is Bothell’s Preferred Chimney Cap & Crown Company
We’ve built our reputation in Bothell on one practice: showing homeowners the problem before asking them to pay for a fix. Every visit includes an NFPA 211 Level 2 camera inspection down the flue. You get photos and a documented record of what we found, whether it’s a spalled clay tile or a corroded chase cover seam. That photo record is Clause 4 of the Haven Standard, and we’ve kept it on every job since 2009. No other company in King or Snohomish County has been running the same archive for that long.
Bothell homeowners tend to be careful researchers. They’ve read the horror stories about $6,000 liner replacements recommended after a 20-minute “inspection” that never went deeper than the firebox. We get it. That’s why our pricing is always written, always itemized, and always delivered before work starts. Corrine Halstead, who runs our operation, has made the written-before-work rule non-negotiable. Bring us a competitor’s written quote and we’ll give you a free second opinion on it, line by line.
We also answer the phone. A live person picks up when you call, 24/7. Not a voicemail box or a web form. If you’re calling from Bothell, you’ll schedule directly and get a named technician assigned with an arrival window. Background-checked, uniformed crews. License number on the page. It’s how we’ve handled every Bothell job since the beginning.
Our Chimney Cap & Crown Services in Bothell
Cap Installation
A new chimney cap in Bothell typically runs $450-$800 for a standard single-flue cap, installed. The right cap keeps rain, moss, and the valley’s persistent fog moisture out of your flue, and it stops birds and rodents from nesting in the dead space above the damper. For Bothell’s prefab fireplaces, we match the cap to the specific chase dimensions and the manufacturer’s listed clearances, not whatever generic cap fits.
Cap Replacement
If your existing cap is rusted through, missing cross-break screens, or was knocked loose in one of the winter windstorms that barrel down the Sammamish River valley, replacement usually runs $500-$950. We see a lot of 30-year-old factory caps on Bothell homes that were never designed to withstand 40 years of fog-soaked winters. When we replace a cap, we photograph the old one and show you exactly what failed, then document the new installation under Haven Standard Clause 4.
Crown Repair
Crown repair on a Bothell home typically costs $600-$1,400 depending on whether we’re patching hairline cracks or rebuilding the entire crown form. Older Bothell chimneys, especially pre-1985 builds near downtown, often have crowns that were originally poured too thin or without a drip edge. Cracks let water soak into the masonry, which then freezes and spalls during rare cold snaps. We rebuild crowns with a proper slope and a functional drip edge so water sheets away from the flue rather than wicking in.
Crown Coating
For crowns that are still structurally sound but showing moisture absorption, we apply a flexible elastomeric crown coating, usually $350-$700. It seals micro-cracks and keeps water from penetrating the crown’s surface. In Bothell’s damp climate, where crowns stay wet for months at a time, this is the difference between a 10-year crown and one that fails in three.

Common Chimney Cap & Crown Problems We See in Bothell Homes
- Fog-soaked metal chase covers rusting through at the seam. Bothell’s low-elevation fog keeps metal components damp for weeks even when it isn’t raining. Chase covers on 1980s and 1990s prefab systems commonly rust through within 20 years, letting rain pour directly into the firebox and smoke chamber. A camera inspection reveals the rust path immediately.
- Clay-tile flue liners spalling under damp, low-heat fires. Many Bothell residents burn small ambiance fires a few times a year using wood that never fully dried in this climate. The combination of low heat and moisture-laden wood accelerates spalling in clay liners from 1980s prefab systems. Chips drop and block the damper, killing draft and sending smoke back into the living room.
- Crowns cracking along the chase flashing on factory-built units. On Bothell’s zero-clearance fireplaces, the crown isn’t a poured concrete cap over brick. It’s a metal chase top that seals around the flue pipe. When that seal cracks, moisture wicks into the chase and delaminates the refractory panels inside the firebox. Homeowners see rust stains on the firebox walls months before they smell anything.
- Moss and lichen colonizing the crown surface. Between the Sammamish River valley’s humidity and the dense canopy in neighborhoods like Canyon Park, crowns stay damp enough to support moss growth. Moss holds moisture against the crown and wicks it into micro-cracks, expanding freeze-thaw damage every winter. We remove it mechanically and coat the crown to slow regrowth.

FAQs - Chimney Cap & Crown in Bothell
Yes, it does. Prefab or zero-clearance fireplaces in Bothell use a metal chase and a factory-specified cap that locks into the chase top, while masonry chimneys use a cap that fastens to the flue tile or crown. On Bothell’s 1985-2005 tract homes, the chimney isn’t brick at all. It’s a wood-framed chase wrapped in siding, and the “cap” is a metal termination that seals the entire chase opening. Installing a masonry-style cap on a prefab system fails within a year because it doesn’t match the chase dimensions or the manufacturer’s clearance requirements. We carry the correct factory-style caps for the major brands installed across Bothell and verify fit with photos before installation. Call (980) 580-8641 and we’ll identify your system type on the first visit.
Yes. The cap’s primary job in Bothell isn’t about fires. It’s keeping rain, fog moisture, and the valley’s damp air out of your flue and chase. A Bothell homeowner who burns three fires a winter still has a chimney exposed to 365 days of moisture. Without a cap, rain goes straight down the flue and pools on the smoke shelf. In a prefab system, it soaks the refractory panels and starts rusting the metal chase from the inside. The cap is doing its work every day, not just when you light a fire. If yours is missing or rusted, call (980) 580-8641 for a free inspection and written cap replacement quote.
It affects permitting and enforcement. Bothell is one of the few cities in the region that spans two counties, so a chimney cap or crown job in North Creek (King County) may involve different permit triggers and inspection requirements than the same work near downtown (Snohomish County). For most cap and crown replacements, no permit is required in either county. But if your repair involves the flue itself, like a chase rebuilding or a liner that connects to a wood-burning appliance, the Puget Sound Clean Air Agency notification requirements can differ depending on which county you’re filing under. We know which jurisdiction applies to your address before we quote, so the written price reflects any permit or notification obligation. That’s a complication our techs handle daily, and it’s written directly into the job scope.
Moss grows on Bothell crowns because the Sammamish River valley’s fog and high humidity keep the surface damp for months. The moss itself isn’t the main problem. It holds a film of moisture against the crown surface, and that water seeps into micro-cracks, then expands during the few hard freezes Bothell gets each winter. Each cycle widens the cracks until water reaches the flue or the chase interior. Some homeowners in the Canyon Park area see moss return every year because of the tree canopy and low light. We remove it as part of crown repair, then seal the surface with an elastomeric coating that resists re-colonization. You’ll see the before and after in your photo record. Call (980) 580-8641 to have us take a look.
Sometimes, yes. If the flue liner is structurally intact but the draft is weak because the existing cap is undersized, wrong for the flue dimensions, or blocked by screens that have choked with creosote, a custom multi-flue cap can restore airflow without touching the liner. We size the cap to the exact flue and chase dimensions, verify clearances with a camera scan, and test the draft after installation. If the liner itself is spalled or separated, a new cap won’t fix the underlying problem. That’s the point of the Level 2 camera inspection: we can show you whether your draft problem is a cap issue or a liner issue before you spend anything. In Bothell’s 30-40-year-old prefabs, it’s often both. We’ll document what we find and give you a written scope for any work you choose to do. Call (980) 580-8641 to schedule the inspection.
