Fast, Reliable Chimney Cap & Crown Across Lake Stevens
A new chimney cap installation in Lake Stevens typically runs $280–$450, while crown repair or coating costs $180–$340, with most jobs completed in a single visit. Horizon Chimney Sweep Washington has been crossing the Snohomish River valley to reach Lake Stevens homeowners since 2007, and our Chimney Cap & Crown crew knows the difference between a masonry crown and the prefabricated metal chase covers that dominate this market. If you’re seeing water stains near your fireplace or hearing animals in the flue, call us at (866) 541-8697 — we stock caps and chase covers sized for Lake Stevens’s common prefab systems and can usually diagnose the problem on arrival.
Why Horizon Chimney Sweep Washington Is Lake Stevens’s Preferred Chimney Cap & Crown Company
We’ve built our reputation in Snohomish County one chimney at a time. Our 1,006 verified reviews averaging 4.8 stars include dozens from Lake Stevens homeowners who found us after other contractors misdiagnosed their chimney problems as roof leaks or simply didn’t understand prefabricated metal systems.
James Wilson, our owner, still works as lead technician on jobs — so when we roll up to your home off Lundeen Parkway or up in the hillside neighborhoods near Frontier Village, you’re getting 17 years of hands-on chimney expertise at your door, not a subcontractor learning on your dime. We’ve replaced enough rusted chase covers in Lake Stevens subdivisions to recognize the pattern before we even climb the ladder: galvanized steel from the 1998–2005 build-out, orange streaking on the chase siding, water damage in the firebox that the homeowner has patched twice.
Our response time to Lake Stevens averages same-day or next-day during the busy season, and we carry Copperfield and Gelco caps in common sizes for the zero-clearance fireplaces found throughout the 98258 ZIP code. That means fewer return trips, less waiting, and a sealed chimney before the next rain rolls in off the Cascades.
Our Chimney Cap & Crown Services in Lake Stevens
Cap Installation
New cap installation in Lake Stevens runs $280–$450 for standard single-flue models, with multi-flue systems starting around $380. Most Lake Stevens homes built during the 1990s–2010s boom came with minimal factory caps — thin galvanized hoods that corrode within a decade in our damp foothill climate. We install Gelco and Copperfield caps with proper overhang and mesh screening, sized to handle the heavy rainfall that Lake Stevens collects from its Cascade slope position. If you’re burning locally cut alder through wet winters, that mesh keeps embers contained and animals out.
Cap Replacement
Cap replacement is our most frequent call in Lake Stevens, typically $220–$390 depending on flue count and access. The original caps on prefab chases in neighborhoods like those along 83rd Avenue NE were never meant to last 25 years. We’ve replaced hundreds in Lake Stevens alone — rusted through, blown off in windstorms, or crushed by falling limbs from the mature Douglas firs that shade many properties. We remove the failed unit, inspect the flue collar for corrosion, and install a replacement that matches or exceeds the original specification. One trip. Done.
Crown Repair
For the minority of Lake Stevens homes with true masonry construction — mostly older properties near the lake itself or custom builds in the North Cove area — crown repair addresses cracked or spalling concrete at the chimney top. We charge $180–$340 for minor crack sealing with HeatShield crown coating material, or $450–$780 for partial rebuilds where the crown has separated from the flue tiles. Lake Stevens’s freeze-thaw cycles are milder than eastern Washington, but the persistent dampness accelerates water infiltration through hairline cracks that would stay dry in a drier climate.
Crown Coating
Crown coating with flexible sealant runs $180–$280 and buys time on a masonry crown that’s cracked but structurally sound. We use HeatShield products for this application — they flex with thermal expansion rather than cracking again the first winter. In Lake Stevens, where chimneys stay damp for months at a stretch, this waterproofing layer prevents the slow saturation that destroys flue liners from the outside in. Not every crown needs rebuilding. Sometimes the right coating adds five to ten years of service.
Multi-Flue Cap
Multi-flue caps cover two or more flues with a single hood, typically $380–$580 installed. Lake Stevens homes with basement fireplaces and main-floor units — common in the two-story plans built during the 2004–2008 wave — often need this solution. A single multi-flue cap from Copperfield protects both flues while maintaining proper draft separation. We measure on-site, fabricate to fit, and install with stainless steel hardware that won’t rust out like the original galvanized brackets.
Custom Cap
Custom caps for odd-size chases, detached workshops, or non-standard flue configurations start at $450 and depend on material and complexity. Lake Stevens’s acreage properties and outbuildings — common west of Highway 9 — often have site-built chimneys that don’t match any catalog part. We template, fabricate, and install caps that fit properly the first time. No cobbling. No gaps where the raccoons get in.

Trusted Brands We Service in Lake Stevens
We install and repair using Copperfield, Gelco, and Famco caps and chase covers — brands that hold up to Lake Stevens’s wet winters and acidic creosote conditions. We keep common sizes in stock for the prefab systems built into most Lake Stevens homes, which means faster turnaround and no waiting for a special order while rainwater keeps entering your flue. For crown coating and repair, we use HeatShield materials — the same products specified by factory-built fireplace manufacturers for warranty-compliant repairs. These aren’t generic hardware-store parts. They’re the components we trust after 17 years of seeing what fails and what endures in Pacific Northwest chimneys.
Common Chimney Cap & Crown Problems We See in Lake Stevens Homes
- Rusted-through galvanized chase covers from the late-1990s build-out. In subdivisions off 20th Street NE and throughout the Frontier Village area, original chase covers have reached or exceeded their service life. The galvanized steel corrodes from the inside out, often showing only minor surface rust while the interior is paper-thin. Rainwater funnels directly into the firebox, and homeowners spend months chasing phantom roof leaks.
- Aging zero-clearance flue liners degraded by acidic creosote. Lake Stevens residents burn heavily — it’s a wood-burning community with a semi-rural character — and locally cut alder and maple is often insufficiently seasoned. The resulting stage-2 and stage-3 creosote deposits are highly acidic, corroding metal flue liners from the inside while the exterior faces persistent damp from our foothill rainfall.
- Improperly sealed chase top connections separating from the flue. Thermal cycling — hot flue gases, cold rain, repeat — causes the chase top to pull away from the flue collar. Gaps open. Squirrels nest. Water enters. We’ve found this condition repeatedly in Lake Stevens’s 2000s-era subdivisions where construction speed outpaced installation precision.
- Factory caps blown off or damaged by wind and falling limbs. Lake Stevens’s mature tree canopy — those same Douglas firs that make the community attractive — drops branches and creates wind turbulence that factory-original caps weren’t designed to survive. A proper replacement with secure mounting and adequate mesh screening prevents recurrence.

FAQs — Chimney Cap & Crown in Lake Stevens
Lake Stevens’s Cascade foothill position captures more rainfall than flatter lowland neighbors, and the lake itself adds localized humidity that accelerates galvanized steel corrosion. The heavy wood-burning culture here — often with under-seasoned local fuel — produces acidic creosote that attacks metal from the inside while exterior moisture works from the outside. Call (866) 541-8697 for a free inspection if your chase cover is original to a 1990s–2000s build.
Yes — we’ve traced dozens of “roof leaks” in that exact area to rusted-through chase covers, not roofing failures. The original galvanized steel covers from Lake Stevens’s late-1990s build-out are now well past rated service life, and the hillside exposure off 20th Street NE sees heavy rainfall runoff. We recently serviced a home off 20th Street NE where the homeowner had been chasing a mysterious roof leak for years. Our crew found that the galvanized steel chase cover, original to the late-1990s build, had rusted through, funneling rain directly into the firebox. We replaced it with a heavy-duty Copperfield multi-flue cap, sealing the chase and stopping the water damage at its source. Call (866) 541-8697 — we’ll diagnose whether it’s your chase cover, flashing, or actual roof issue.
Yes, multi-flue cap installation is a core service, typically $380–$580 in Lake Stevens. Homes with basement and main-floor fireplaces — common in 2000s-era two-story plans throughout the 98258 ZIP code — benefit from a single protective hood that covers both flues while maintaining proper draft separation. We measure and fabricate on-site for exact fit. Call (866) 541-8697 to schedule measurement.
Yes, custom caps start at $450 and we template on-site for exact fit. Lake Stevens’s acreage properties and outbuildings — particularly west of Highway 9 — often have site-built chimneys that don’t match standard catalog dimensions. We fabricate from stainless steel or copper as specified, with proper overhang and animal screening. Call (866) 541-8697 to describe your configuration and schedule a template visit.
For Lake Stevens’s combination of high rainfall and acidic creosote conditions, we typically recommend Copperfield stainless steel caps or Gelco’s heavy-gauge models with expanded mesh. Both withstand the damp foothill climate and resist corrosion from wood smoke byproducts better than standard galvanized units. The right choice depends on your flue count, chase dimensions, and whether you’re burning primarily hardwood or softwood. Call (866) 541-8697 — James Wilson can assess your specific setup and recommend accordingly.
