Why Horizon Chimney Sweep Washington Is Alderwood Manor’s Preferred Chimney Cap & Crown Company
We’ve built our reputation in Alderwood Manor one 90-year-old chimney at a time. Our 1,006 verified customer reviews — averaging 4.8 stars — include dozens from homeowners right here in the 98036 ZIP who initially called for a routine sweep and discovered they needed crown work once we pulled the cap. That pattern recognition matters. James Wilson arrives at your door as the lead technician, not a subcontractor learning Alderwood Manor’s housing stock on your dime.
Our response time to Alderwood Manor averages same-day or next-day because we’re already working this corridor regularly — Lynnwood, Brier, Mountlake Terrace, and Bothell East are all within our daily route. We don’t waste your time with generic recommendations. We know that a 1935 farmhouse chimney near 212th Street SW needs a different approach than a 1968 split-level off 44th Avenue W, and we stock the parts — Gelco coatings, Copperfield custom caps, Olympia Chimney hardware — to handle both without a second trip.
Our Chimney Cap & Crown Services in Alderwood Manor
Crown Repair
Crown repair is our most common call in Alderwood Manor, and there’s a reason rooted in this specific dirt. The original agricultural colony homes were built with lime mortar that the Pacific Northwest rain has been dissolving for 90–100 years. When that crown cracks — and it will — water funnels straight into the chimney’s core, rotting attic sheathing and destabilizing the entire structure. We rebuild crowns with proper Portland-based mortar formulations and slope them correctly so water sheds instead of pools. On a 1930s farmhouse on 164th Street SW, we found the original clay flue tile had disintegrated under a cracked, moss-covered crown. We installed a custom copper multi-flue cap from Copperfield and coated the rebuilt crown with Gelco elastomeric sealant, stopping years of moisture intrusion that had already rotted the attic sheathing.
Crown Coating
For crowns with surface cracking but intact structural integrity, crown coating buys Alderwood Manor homeowners another 8–12 years before full rebuild becomes necessary. We apply Gelco’s elastomeric crown coat — a flexible, waterproof membrane that bridges hairline cracks and resists the freeze-thaw cycling that destroys standard mortar in our 20–30 sub-freezing nights per year. This is preventive medicine for your chimney, and in Alderwood Manor’s climate, it’s almost always worth doing before the first hard freeze.
Custom Cap Installation
Standard caps fail Alderwood Manor’s older chimneys twice over. First, the unlined or informally modified flues from 1970s wood-stove retrofits create irregular openings that stock caps can’t seal. Second, the coastal salt air accelerates corrosion on galvanized hardware within 3–5 years. We fabricate and install custom caps using Copperfield and Famco components — stainless steel where salt air attacks, proper sizing where irregular flues demand it. A cap that doesn’t fit is a cap that doesn’t protect.
Cap Replacement
When an existing cap has corroded through, blown off in a windstorm, or was never properly sized to begin with, we remove and replace with correct-fit hardware. In Alderwood Manor’s tree-shaded lots, we frequently find caps that were doing their job mechanically but were overwhelmed by moss and debris accumulation — the cap was fine, but the crown beneath it had already failed. We check both. Every time.

Trusted Brands We Service in Alderwood Manor
We don’t guess at material quality. For Alderwood Manor’s specific challenges — salt air corrosion, moss infiltration, and the thermal expansion of 90-year-old brickwork — we specify Gelco elastomeric coatings for crown waterproofing, Copperfield and Famco for custom and multi-flue cap fabrication, and Olympia Chimney for replacement components that meet current Washington State code. These aren’t off-brand substitutes; they’re what we install on our own homes. We stock the common sizes locally, so most Alderwood Manor cap and crown jobs don’t wait on shipping.
Common Chimney Cap & Crown Problems We See in Alderwood Manor Homes
- Moss and lichen colonization wicks moisture into crowns. On Alderwood Manor’s older tree-shaded lots, moss doesn’t just grow on roofs — it establishes on chimney crowns and open mortar joints, creating a sponge that pulls water directly into the masonry. Through 20–30 annual freeze-thaw cycles, that moisture expands and destroys the crown from within.
- Original lime mortar dissolves under persistent rain. The 1920s–1940s agricultural colony homes were built with period lime mortar that lacks the hydraulic properties of modern Portland cement. After 90–100 years of 35+ inches of annual rainfall, that mortar turns to sand. Crowns crumble. Joints go missing. We see this on nearly every original chimney in the 98036 ZIP.
- 1970s wood-stove inserts created irregular flue openings. When the energy crisis hit, Alderwood Manor homeowners retrofit wood stoves into existing fireplaces — often with informal flue modifications that created uneven, oversized, or offset openings. Standard caps don’t seal these. Water and debris enter freely. Custom fabrication is the only fix that works.
- Coastal salt air accelerates metal corrosion. Alderwood Manor’s proximity to Puget Sound means salt-laden air attacks galvanized cap hardware and fasteners years faster than inland locations. We’ve replaced 3-year-old caps from other installers that looked 15 years old. We specify stainless steel for coastal exposure.

FAQs — Chimney Cap & Crown in Alderwood Manor
Alderwood Manor’s 1920s–1940s lime-mortar chimneys, combined with roof moss wicking moisture into crowns through 20–30 annual freeze-thaw cycles, destroy crown integrity faster than the Portland-cement construction found in 1960s+ suburbs. Crown coating every 8–10 years is preventive maintenance here, not an upsell. Call (866) 541-8697 and we’ll assess whether your crown is a coating candidate or needs rebuild.
Probably not. Original agricultural colony chimneys in Alderwood Manor frequently have unlined flues or irregular openings from 1970s wood-stove modifications that standard caps cannot seal. We measure on-site and fabricate custom caps from Copperfield or Famco components when needed. Call (866) 541-8697 for a free measurement and estimate.
Roof moss colonizes chimney crowns and open mortar joints, creating a living sponge that holds moisture against the masonry through freeze-thaw cycles. In Alderwood Manor’s tree-shaded 98036 lots, this is nearly universal on homes older than 60 years. We remove moss during crown work and specify coatings and caps that resist re-colonization. Call (866) 541-8697 if you see moss on your chimney.
We specify stainless steel for all Alderwood Manor cap hardware because coastal salt air from Puget Sound corrodes galvanized fasteners and frames within 3–5 years. Stainless costs more upfront but eliminates replacement labor. Call (866) 541-8697 and we’ll walk you through material options for your specific exposure.
In most cases, yes. We’ve rebuilt crowns on 90–100-year-old Alderwood Manor chimneys where the underlying brick is still structurally sound. We assess brick integrity, flue condition, and lateral stability before recommending anything. Full replacement is rare; targeted crown repair with proper coating is our standard outcome. Call (866) 541-8697 for an honest assessment.
