Fast, Reliable Chimney Cap & Crown Across Cedar Hills
Chimney cap and crown repair in Cedar Hills typically runs $280–$890 depending on whether we’re sealing a hairline crack or rebuilding a spalled crown from the 1960s, and most jobs are completed in a single visit. If you’re smelling mildew near your fireplace or spotting orange rust stains on the brickwork, the crown or cap has likely failed and water is running down your flue.
We’ve been driving out to Cedar Hills from our Seattle base for years, and we know the 97005 zip well — the ranch homes off Cedar Hills Boulevard, the split-levels tucked behind the old Fred Meyer, the mid-century tracts that climb toward the Tualatin Mountains. These houses were built fast in the 1950s through 1970s, and their chimneys are showing it. James Wilson, our owner and lead technician, has spent 17 years diagnosing exactly how Pacific Northwest moisture destroys lightweight concrete crowns on aging single-wythe brick. When you call (866) 541-8697, you’re getting that experience at your door — not a subcontractor reading from a checklist.
Why Horizon Chimney Sweep Washington Is Cedar Hills’s Preferred Chimney Cap & Crown Company
Our Chimney Cap & Crown team has built a reputation in Cedar Hills through repeat customers who’ve watched us pull apart failed crowns and show them exactly where the water got in. With 1,006 verified reviews averaging 4.8 stars, we’ve earned trust at real scale — not a handful of curated testimonials, but documented feedback from homeowners who’ve had us back for annual sweeps and bigger repairs alike.
Response time matters when water’s pouring down your flue during a November storm. We typically schedule Cedar Hills appointments within 2–4 business days, and we carry Gelco, Olympia Chimney, and Famco caps and crown materials on our trucks so we’re not ordering parts and making you wait through another rainy week. James Wilson handles the diagnostic work personally, which means when we recommend a crown rebuild over a simple coating, you’re getting a judgment call from someone who’s crawled across hundreds of Cedar Hills–style roofs and knows what survives the next 20 freeze-thaw cycles.
Our Chimney Cap & Crown Services in Cedar Hills
Custom Cap Installation
Standard flat caps from the tract-builder era don’t cut it in Cedar Hills. The original caps on these 1950s–1970s homes lack a proper overhang, so water rolls back under the lip and straight into the brickwork — a problem amplified by the heavier rainfall this foothill-adjacent pocket gets compared to flat Portland. We measure your flue precisely and fabricate custom caps with a minimum 2-inch overhang and integrated drip edge, typically in galvanized steel or copper. A custom cap for a Cedar Hills ranch runs $340–$620 installed, and we size them specifically for the oddball flue dimensions common on homes from this era.
Crown Repair & Coating
This is where Cedar Hills’s housing stock shows its age most dramatically. The original lightweight concrete crowns were undermixed by builders working fast during the postwar boom, and 50–70 years of Pacific Northwest moisture cycling has spalled them into porous, cracked shells. On a ranch home near Cedar Hills Boulevard, we found the original 1960s concrete cap had delaminated into shards, allowing water to run down the flue and saturate the clay tile liner. We demoed the old crown, installed a new Olympia Chimney crown with a 2-inch overhang and drip edge, and sealed the top with HeatShield CrownCoat. The homeowner had been smelling mildew for years — now the chimney is dry.
For crowns with intact structural integrity but surface cracking, we apply HeatShield CrownCoat after cleaning and priming the concrete. This runs $280–$450 in Cedar Hills. For crowns that have spalled past saving, we form and pour a new crown with proper slope and overhang — $650–$890. The difference is whether we can still trust the concrete underneath.
Multi-Flue Cap Systems
Many Cedar Hills split-levels and two-story ranches have multiple flues sharing a single chimney structure — often one for a basement fireplace and one for the main floor, or a fireplace paired with a furnace vent. Single caps leave gaps where water and debris enter the unused flue. Our multi-flue cap systems cover the entire chimney top as one integrated unit, with screened vents sized to each flue’s draft requirement. These run $580–$940 installed in Cedar Hills, and we spec them from Famco and Olympia Chimney lines that hold up to the wind exposure coming off the Tualatin Mountains.
Cap Replacement for Failed or Missing Units
It’s common in Cedar Hills to find caps completely missing — blown off in a winter storm years ago and never replaced, or removed by a previous homeowner who didn’t understand the function. Without a cap, rain enters freely, and the roughly 20–30 overnight freezes each winter expand that moisture inside the flue tiles until they crack. We stock replacement caps for standard flue sizes and can measure and install same-day for most Cedar Hills homes. Basic galvanized replacement: $220–$380. Stainless or copper upgrade: $420–$680.

Trusted Brands We Service in Cedar Hills

When we recommend HeatShield CrownCoat for a cracked crown, it’s because we’ve tracked its performance through enough local winters to trust the bond.
Common Chimney Cap & Crown Problems We See in Cedar Hills Homes
- Spalled original crowns from undermixed 1960s concrete. The lightweight crowns on Cedar Hills’s mid-century homes were never formulated to survive decades of saturation. We regularly find them reduced to gravel-like debris that crumbles at finger pressure, exposing the flue to direct rainfall.
- Gas inserts dropped into unlined or tile-lined flues without proper venting. A configuration quietly common in 1960s Cedar Hills retrofits, these create negative pressure that sucks moisture past any cap compromise. The cap isn’t the root problem, but it’s where the symptoms show up as rust stains and draft issues.
- Flat builder-grade caps with zero overhang. Water runs backward into the brickwork, accelerating mortar joint decay that’s already advanced from years of heavy rainfall. By the time homeowners notice interior damage, the cap has been failing for multiple seasons.
- Thermal shock cracking from freeze-thaw cycles. Cedar Hills’s 20–30 annual freezes don’t sound extreme, but they’re perfectly timed to exploit moisture-laden clay tile liners and crown concrete. A cap that was intact in October can show new gaps by March.

What moves you up or down within these ranges? Crown height and roof pitch affect labor time — a two-story split-level with steep access costs more than a single-story ranch we can walk right up to. The extent of hidden water damage underneath a failed crown sometimes requires additional brick repair before we can pour new concrete. And material choice matters: copper develops a patina that some Cedar Hills homeowners love, others want the clean look of stainless at a lower price point. We give exact quotes after inspection, and estimates are free. Call (866) 541-8697 to schedule.

FAQs — Chimney Cap & Crown in Cedar Hills
Repair with crown coating works if the concrete is structurally sound and cracks are surface-level; rebuild if the crown has spalled, delaminated, or lost more than 25% of its mass. In Cedar Hills, we see so much spalling from undermixed original concrete that rebuilds outnumber coatings roughly two to one on homes from this era. Call (866) 541-8697 for a free inspection — we’ll show you exactly what you’re working with.
You need a cap sized to the insert’s venting requirements, and often a new stainless liner run the full flue length. The unlined gas insert retrofits common in 1960s Cedar Hills homes create draft problems that a cap alone won’t fix. We assess the full venting system, not just the cap, because slapping a new cap on a misconfigured flue masks the real hazard.
Every year, ideally before the October rains begin. Cedar Hills’s wet season runs eight months, and the 20–30 annual freezes concentrate damage in the cap and crown. A cap that looked fine in September can have new cracks by February. We bundle cap inspection with annual sweeping appointments.
Copper runs 30–40% above stainless but develops a protective patina that resists the salt and acid rain common in Pacific Northwest coastal-influenced air. For Cedar Hills homes where the cap is highly visible from the street, many homeowners prefer copper’s aging character. For purely functional protection, 304 stainless from Gelco or Olympia Chimney lasts 15–20 years at lower cost.
Orange staining is rust from a galvanized cap that’s losing its zinc coating, or from flue gases condensing and corroding the metal from underneath. In Cedar Hills, we see this accelerated by the longer wet season — moisture sits on the cap surface instead of evaporating quickly. The stain is your warning that the cap is thinning and will soon leak. Call (866) 541-8697 and we’ll measure for a replacement before the next heavy rain.
