We’ve been climbing Kenton roofs since before the condos went up along Interstate Avenue. Our Chimney Cap & Crown team knows the rhythm of this neighborhood: the 1910s Craftsman bungalows packed tight on 25-foot lots, the foursquares on N. Denver Avenue with their original brick chimneys poking above sagging gutters, the alley-loaded garages where ladder placement takes more planning than the repair itself. James Wilson, our owner and lead technician, brings 17 years of chimney-only experience to every Kenton job. We’ve got 1,006 verified reviews averaging 4.8 stars because we show up, diagnose honestly, and fix what’s actually broken — not what pads an invoice.
Why Horizon Chimney Sweep Washington Is Kenton’s Preferred Chimney Cap & Crown Company
Kenton homeowners don’t call us for slick marketing. They call because their neighbor on N. Kilpatrick had a crown crack that dripped through the plaster, or because the inspector flagged efflorescence on a bungalow near The Green Man of Portland before closing. Word travels fast in 97217.
Those 1,006 reviews at 4.8 stars aren’t from a lucky month — they’re from 17 years of showing up to Kenton homes, finding the real problem, and pricing it straight. James Wilson is the one at your door, not a subcontractor learning chimneys between gutter jobs. He knows Kenton’s housing stock: the lime-mortar joints that crumble differently than Portland cement, the clay flue liners that crack in freeze-thaw, the informal “repairs” from decades past that now trap moisture against century-old brick.
We keep common cap sizes and crown coating materials stocked for Kenton’s typical single-flue and multi-flue configurations. Most parts orders don’t delay your job. From Kenton to Kings Heights to Irvington, we’re familiar with the access constraints — narrow side yards, overhead wires, flat roofs that complicate ladder placement — and we plan accordingly before arriving.
Our Chimney Cap & Crown Services in Kenton
Custom Cap Fabrication & Installation
Kenton’s original lime-mortar chimneys, exposed to Portland’s 37 inches of annual rain and freeze-thaw cycles, are uniquely prone to crown spalling and mortar joint failure, making cap replacement a structural necessity, not just a convenience. Generic big-box caps don’t fit these old flues properly — the dimensions vary, the flue tiles are often irregular, and a loose cap blows off in the first winter storm. We measure on-site and fabricate custom caps from Copperfield and Famco materials, with rolled edges and proper overhang that sheds water away from deteriorating mortar. A proper custom cap on a Kenton bungalow can add 15–20 years to a crown’s life by stopping the saturation cycle that destroys lime mortar.
Multi-Flue Cap Systems
Many Kenton foursquares and duplex conversions have multiple flues clustered on one chimney shoulder — a fireplace flue, an old oil-furnace flue, maybe a former water-heater vent. Single caps leave gaps; multi-flue caps cover the whole assembly. We size and install Olympia Chimney multi-flue systems with stainless-steel mesh that keeps out North Portland’s starlings and swallows while maintaining proper draft for each flue. On a 1924 Craftsman on N. Denver Avenue in Kenton, we found the original clay-tile crown had been replaced decades ago with plywood, trapping a starling nest on top of a half-inch of creosote. We installed a custom Copperfield multi-flue cap with rolled edges and a stainless-steel mesh that keeps out North Portland’s swallows while allowing proper draft.
Crown Repair & Rebuilding
The crown is the concrete or mortar wash that seals the chimney top between the flue tiles and the brick edge. On Kenton’s pre-WWII chimneys, these were often poured too thin, mixed with substandard aggregate, or simply never maintained. Original lime-mortar chimneys develop hairline crown cracks during freeze-thaw cycles, letting rain wick into clay flue liners and accelerate spalling behind the cap. We remove deteriorated material, re-form with proper slope and drip edge, and seal with crown-specific compounds that flex with temperature swings. For chimneys with significant mortar loss, we rebuild the crown structure before capping — otherwise you’re trapping water under a new cap with nowhere to go.
Crown Coating & Waterproofing
Not every cracked crown needs rebuilding. If the structural integrity is sound — no exposed brick, no spalling, no through-cracks — a professional crown coating can extend service life 5–10 years. We use HeatShield and Copperfield crown coating products formulated for Portland’s wet climate, applied after thorough cleaning and minor crack repair. This is often the right call for Kenton homeowners who’ve caught deterioration early, before freeze-thaw cycles have opened gaps that let water reach the flue liner. We assess honestly: coating a crown that’s too far gone is wasted money, and we’ll tell you when rebuild is the only durable option.

Trusted Brands We Service in Kenton
We install and repair with Copperfield, Famco, and Olympia Chimney caps and components — brands that hold up to Portland’s relentless moisture instead of rusting through in three seasons. For crown work, we use HeatShield refractory compounds and Copperfield waterproofing systems. These aren’t hardware-store specials; they’re professional-grade materials with documented performance in wet climates. We stock common Kenton sizes and configurations, so most cap installations don’t wait on shipping. When a custom fabrication is needed, our supplier relationships keep turnaround to a few days, not weeks.
Common Chimney Cap & Crown Problems We See in Kenton Homes
- Freeze-thaw crown destruction: Original lime-mortar chimneys develop hairline crown cracks during freeze-thaw cycles, letting rain wick into clay flue liners and accelerate spalling behind the cap. By the time water drips down interior walls, the damage is extensive.
- Improvised caps trapping nests and moisture: Improper caps (plywood, sheet metal) collect nesting debris from North Portland’s abundant starlings and swallows, blocking flues and trapping moisture against old creosote, creating fire and CO risks. We’ve pulled nests a foot deep from chimneys capped with nothing but a piece of aluminum siding.
- Hidden deterioration in alley-loaded housing: Kenton’s dense, alley-loaded housing means chimney crowns are often hidden from view for years; deferred maintenance leads to silent mortar loss that only shows after a heavy rain drips down interior walls. The chimney is literally out of sight, out of mind — until it isn’t.
- Failed mortar joints under existing caps: Even properly capped chimneys suffer when mortar joints behind the cap erode. Water finds the path of least resistance, and on Kenton’s 80–100-year-old chimneys, that path is often the joint between the flue tile and the crown, or the brick courses just below it.

FAQs — Chimney Cap & Crown in Kenton
Kenton’s pre-WWII chimneys were built with non-standard flue dimensions and irregular clay tile tops that don’t accept modern universal caps. The original lime-mortar construction also means the crown surface is often uneven or partially eroded, requiring a cap that’s measured and fabricated to fit the actual chimney, not a catalog size. Call (866) 541-8697 and we’ll measure yours for an exact fit — estimates are free.
Crown coating works when cracks are hairline, the underlying mortar is sound, and there’s no spalling or exposed brick. If the crown has through-cracks, crumbling edges, or brick showing through, coating will fail within a season — rebuild is the only durable fix. We assess this honestly during inspection and won’t sell you a coating that won’t last. Call for a free evaluation.
Portland’s 37 inches of annual rain and North Portland’s river-proximity humidity keep chimney crowns saturated for months, accelerating lime-mortar erosion and giving freeze-thaw cycles more damage to work with. Crown work in Kenton requires materials rated for persistent moisture exposure and installation techniques that ensure proper drainage — otherwise you’re patching a boat that’s still leaking. We specify products and slopes for this climate specifically.
If your foursquare has multiple flues — common in homes that originally had fireplace plus furnace or water heater — a multi-flue cap protects the entire chimney top and eliminates the gaps between single caps where debris and water enter. Many Kenton foursquares have two or three flues that were capped individually decades ago, with one or more caps now missing or deteriorated. We inspect and measure; if multiple flues are present, multi-flue coverage is usually the better long-term investment. Call for specifics on your chimney.
A century-old Kenton chimney needs a cap with proper clearance above the flue tile (to allow draft), rolled edges that shed water away from mortar joints, and mesh small enough to block North Portland’s starlings and swallows. Stainless steel or copper from Copperfield or Famco outlasts galvanized steel in Portland’s wet climate. We avoid lightweight aluminum on old chimneys — it doesn’t hold up to wind and doesn’t have the mass to stay seated on eroded crowns. James Wilson selects material based on your chimney’s actual condition, not a one-size-fits-all approach.
