Our Chimney Cap & Crown Services in Kenmore
Crown Repair
Crown repair in Kenmore demands more than slapping on sealant and hoping. The concrete crowns on 1950s–1970s ranch and split-level homes throughout the 98028 ZIP were poured with minimal reinforcement and have endured decades of saturation from Kenmore’s persistent lake-proximity humidity. We grind out deteriorated concrete, rebuild with proper slope and drip edge, and finish with a waterproof membrane compatible with HeatShield crown coating systems. A typical crown repair in Kenmore runs $480–$890.
Custom Cap
Kenmore’s older homes often feature non-standard flue configurations — two clay tiles side-by-side, an oversized single flue, or a flue paired with a vented thimble for a former oil furnace. Off-the-shelf big-box caps won’t seat properly, leaving gaps where driving rain enters. We fabricate and install custom multi-flue caps using Copperfield and Olympia Chimney components, measured on-site for your exact chimney profile. Custom cap installation in Kenmore typically costs $650–$1,200 depending on metal grade and flue count.
Crown Coating
For crowns with surface crazing or minor spalling but intact structural integrity, crown coating extends service life 5–10 years at roughly half replacement cost. We use HeatShield’s specialized crown resurfacing compound, formulated to bond with weathered concrete and flex through freeze-thaw cycles. In Kenmore’s damp climate, this is often the right middle path — but only if the crown hasn’t already cracked through to the flue surround. Crown coating in Kenmore runs $280–$450.
Cap Installation & Replacement
Missing or improperly sized caps are the single most preventable cause of water damage we find in Kenmore homes. We install Gelco stainless steel and Famco galvanized caps with proper screening to exclude birds and debris without restricting draft. Standard single-flue cap replacement in Kenmore costs $180–$340 installed; multi-flue systems run $380–$620.

Trusted Brands We Service in Kenmore
We stock and install caps and crown materials from Gelco, Olympia Chimney, Famco, and Copperfield — brands that hold up to Kenmore’s wet winters rather than corroding within three seasons. Because we keep common sizes and multi-flue configurations on our Seattle service vehicles, most Kenmore cap replacements don’t require a return trip. For crown work, we pair HeatShield resurfacing compounds with DuraFlex liner components when flue integrity is compromised, giving you a system repair rather than a surface patch.
Common Chimney Cap & Crown Problems We See in Kenmore Homes
- Subsurface crown fractures invisible from the ground. Kenmore’s lake-moisture cycle keeps concrete crowns saturated for months, and freeze-thaw action opens hairline cracks below the surface that only reveal themselves during close inspection. We’ve pulled apart crowns that looked sound from the driveway but crumbled under probe pressure.
- Clay flue liner displacement behind intact-looking crowns. The original clay tiles in 1950s–1970s Kenmore chimneys crack from decades of thermal cycling, creating hidden pathways for moisture and combustion gases. Water stains on your ceiling may originate from liner failure, not crown failure — and fixing one without diagnosing the other wastes your money.
- Moss and lichen trapping moisture against metal caps. North-facing chimney stacks throughout Kenmore’s mature neighborhoods — especially those shaded by Douglas firs — develop biological colonies that hold water against cap seams and crown edges, accelerating corrosion the cap manufacturer never anticipated.
- Lake-fog corrosion on lower-elevation homes. Properties near the Kenmore waterfront and along the Burke-Gilman Trail corridor see notably faster cap deterioration than hillside homes just blocks away. Minimal wind scour and persistent ground-level fog create conditions that inland Bothell chimneys simply don’t experience.

We Also Serve Cities Near Kenmore
Our service radius covers the full north Lake Washington corridor. We regularly perform chimney cap and crown work in Lake Forest Park, where hillside drainage patterns create their own moisture issues; Bothell, including both Bothell East and Bothell West, where drier inland conditions produce different failure timelines than Kenmore’s lakeside microclimate. Same technician standards, same brand-grade materials, same response commitment.

FAQs — Chimney Cap & Crown in Kenmore
Yes. Clay flue liners from the 1960s have typically endured 60 years of thermal cycling, and in Kenmore’s wet climate that cycling happens while the liner is often damp — accelerating hairline cracking and tile displacement. We inspect the full flue length with a camera before any crown work; if the liner is compromised, we’ll recommend a DuraFlex stainless relining rather than rebuilding a crown on a failed foundation. Call (866) 541-8697 and we’ll camera-inspect at no charge with your crown estimate.
Kenmore’s position at the northern tip of Lake Washington creates a persistently humid microclimate that suppresses summer drying and extends the corrosion season year-round. Bothell sits inland enough to experience lower humidity and more wind scour — conditions that let caps dry between rain events. In Kenmore, especially on lower lots near the Burke-Gilman Trail, caps stay damp for weeks at a stretch. We specify 304-grade stainless or copper for Kenmore installations rather than galvanized steel that might suffice inland.
Crown coating works when the concrete is structurally sound with surface crazing or minor spalling — typically crowns under 25 years old in drier climates, or 40–50 year old Kenmore crowns that have been lucky enough to drain well. We test with a hammer probe and visual inspection; if the crown sounds hollow, shows through-cracks, or has separated from the flue surround, coating buys you months, not years. A proper coating with HeatShield in Kenmore runs $280–$450 versus $950–$1,400 for full replacement. We’ll tell you honestly which path your crown qualifies for.
Homes along and near the Burke-Gilman Trail in Kenmore sit at lower elevation with reduced air movement, and the trail’s tree-lined corridor traps lake fog against chimney stacks for longer periods than open hillside properties. We routinely find crowns in this zone with advanced freeze-thaw fracturing while identical homes three blocks uphill show minimal damage. If you’re in this corridor, we recommend annual inspection rather than biennial — the moisture exposure justifies the frequency.
A custom multi-flue cap is worth it when you have two or more flues that standard caps can’t cover without gaps, or when your flues are irregularly spaced — common in 1960s Kenmore homes where a fireplace flue and former furnace vent share the crown. A single properly fitted custom cap eliminates the leak points of multiple individual caps and costs $650–$1,200 installed versus $360–$680 for two separate standard caps that may not seal. For homes in Kenmore’s wet zone, the unified coverage pays for itself in prevented water damage. Call (866) 541-8697 for exact measurements and a free quote.
