Fast, Reliable Chimney Cap & Crown Across Five Corners
Chimney cap and crown repair in Five Corners typically costs $280–$950 depending on whether you need a simple cap swap or full crown rebuild, and most jobs are completed in a single visit. If you’re seeing water stains on your ceiling near the fireplace or hearing dripping in the chase after rain, the culprit is almost always a failed cap or deteriorated crown — and in Five Corners’s 1980s–1990s housing stock, it’s usually the original prefab chase cover that’s finally given out after decades of Columbia basin moisture.

We’re Horizon Chimney Sweep Washington, and we know the Five Corners corridor well — from the ranch homes near Curtain Creek Wetlands Nature Area Information Board to the two-story tracts off Northeast 78th Street and Northeast Fourth Plain Boulevard. James Wilson, our owner and lead technician, has spent 17 years diagnosing chimney failures in exactly the kind of prefab fireplaces that dominate the 98662 ZIP code. When you call (866) 541-8697, you’re getting hands-on expertise at your door, not a subcontractor reading from a checklist. Our Chimney Cap & Crown team carries the specific cap sizes and crown coating materials needed for the factory-built units common here, so we rarely need to order parts and wait.
Why Horizon Chimney Sweep Washington Is Five Corners’s Preferred Chimney Cap & Crown Company
Five Corners homeowners have left us over 1,006 verified reviews averaging 4.8 stars — and a significant share of those come from repeat customers in the Green Meadows, Orchards, and Minnehaha areas who started with a cap replacement and came back for annual sweeps. That sustained trust matters more than any slogan we could write.
James Wilson personally leads the diagnostic on cap and crown calls. After 17 years exclusively in chimneys, he can spot a rusted Famco chase cover or cracked crown mortar from the ground — and explain exactly why your 1989 prefab fireplace is leaking when your neighbor’s 2005 masonry chimney isn’t. That pattern recognition saves time and prevents the “replace everything” oversell we’ve seen from generalist contractors who split their week between gutters and chimneys.
Our response time to Five Corners is typically same-day or next-day during the fall rush, because we’re based in Seattle and regularly service the Clark County corridor. We know the local reality: Southwest Clean Air Agency no-burn days compress the usable season, so when a Five Corners homeowner discovers their fireplace is legally off-limits on the first cold night, they need cap and crown work done fast before the next restriction window hits.
Our Chimney Cap & Crown Services in Five Corners
Custom Cap Installation & Replacement
In Five Corners, “custom cap” usually means fitting a new cover to an existing prefab chase that’s rusted through at the seams. The original sheet-metal chase covers installed during the 1980s and 1990s building boom weren’t designed to survive 25–40 years of valley fog and temperature inversions. We measure on-site and fabricate caps from stainless steel or copper-grade materials — often using Copperfield or Famco components — to match your chase dimensions exactly. A typical custom cap installation in Five Corners runs $450–$780, including removal of the corroded original and sealing the new base to the crown.
Multi-Flue Cap Systems
Shared chase setups are common in the duplexes and townhome-style builds near Northeast 72nd Avenue. When one flue’s cap fails, both flues are exposed — and the uncoated steel bases on original multi-flue caps expand and contract until the welds crack. We replaced a rusted multi-flue cap on a prefab fireplace in the Green Meadows neighborhood off Northeast 162nd Avenue. The original 1989 Famco chase cover had corroded at the weld seams, sending rainwater down two B-vents. Our crew installed a new custom Copperfield cap with stainless steel base and sealed the crown with Gelco coating. Multi-flue cap replacement in Five Corners typically costs $680–$950 depending on chase height and access.
Crown Repair & Rebuild
True masonry chimneys are rare in Five Corners, but they exist — usually on custom builds from the same era. The crown mortar on these chimneys crumbles from freeze-thaw cycles amplified by valley fog that keeps bricks damp for weeks. James Wilson assesses whether the crown can be patched or needs full rebuild, and we use HeatShield or Gelco crown-specific materials for repairs that outlast standard mortar. Crown repair in Five Corners runs $380–$650; full rebuild starts around $720.
Crown Coating & Waterproofing
For prefab chases with intact structural crowns but surface deterioration, crown coating is the cost-effective play. We apply Gelco’s flexible crown coat — it bridges hairline cracks and sheds water without the weight of new mortar. This is particularly valuable in Five Corners’s climate, where the wet season runs October through April and moisture gets trapped against structures for months. Crown coating typically costs $280–$420 and adds 10–15 years of protection.

Trusted Brands We Service in Five Corners
We stock and install DuraFlex, HeatShield, Gelco, and Copperfield components — the brands that professional sweeps specify when they want repairs to last through multiple wet seasons. For Five Corners’s prefab-heavy housing stock, that means stainless chase covers that won’t rust through at the seams, and crown coatings that flex with temperature swings instead of cracking. Because we carry common cap sizes and coating materials on our service vehicles, most Five Corners customers get same-visit completion rather than a two-trip delay.
Common Chimney Cap & Crown Problems We See in Five Corners Homes
- Rusted prefab chase covers leaking into attic spaces. The original sheet-metal covers on 1980s–1990s factory-built fireplaces develop pinhole rust at seams after decades of Columbia basin dampness, sending water down B-vents and soaking attic insulation and ceiling drywall below — often with no visible exterior damage until the ceiling stains appear.
- Crown mortar crumbling on rare masonry chimneys. The few masonry chimneys in Five Corners suffer accelerated freeze-thaw damage because valley fog keeps brickwork saturated for weeks at a time, expanding cracks in crown mortar that would dry out faster in a drier climate.
- Multi-flue cap weld failures on shared chases. Duplex and multi-family builds near Barberton and Brush Prairie often have uncoated steel multi-flue caps where thermal expansion has broken factory welds, separating the cap from flue tile and creating gaps that swallow rain and nesting material.
- Neglected flues with debris accumulation after years of disuse. Mild Five Corners winters lead many homeowners to skip fireplace use for seasons, then light a fire in October without checking — only to discover squirrels or birds have nested in the unprotected flue, or that creosote has concentrated in the absence of regular burns.

What moves you up or down within these ranges? Chase height and roof access matter — a two-story home off Northeast Fourth Plain Boulevard with a steep roof pitch takes longer than a single-story ranch near Curtain Creek Wetlands. The condition of the existing crown base affects whether we can cap directly or need prep work. And prefab versus masonry construction changes material and labor requirements significantly. We provide exact quotes after on-site inspection — call (866) 541-8697 to schedule, estimates are free.

FAQs — Chimney Cap & Crown in Five Corners
At 37-plus years old, your original prefab chase cover is almost certainly rusted at the seams if it hasn’t been replaced. We see this constantly in the 98662 corridor — the sheet-metal covers from that era simply weren’t built to survive four decades of Columbia basin moisture. Call (866) 541-8697 and James Wilson can confirm with a quick on-site look; estimates are free.
We don’t recommend it. Prefab chase covers must be properly sealed to the crown to prevent water entry, and the wrong cap size or material can restrict draft or void manufacturer specifications. The safety risk is moderate — a poorly installed cap can trap carbon monoxide or accelerate rust — so we suggest having a trained technician measure and install. Call (866) 541-8697 for an exact quote.
It typically doesn’t — crown coating at $280–$420 is usually less than custom cap replacement at $450–$780. If you’ve been quoted higher for coating, the contractor may be including crown prep or repair that a cap-only job doesn’t need. Ask us for a breakdown: (866) 541-8697.
Only if your home has a shared chase with two or more flues — common in duplexes and some townhomes near Northeast 72nd Avenue. Single-family ranches in Green Meadows typically need single-flue caps. James Wilson can identify your chase configuration during inspection.
A properly applied Gelco crown coating lasts 10–15 years even in Five Corners’s extended wet season, provided the underlying crown structure is sound. The key is application during dry conditions — we watch the forecast and schedule accordingly. For a free inspection and coating quote, call (866) 541-8697.
