Fast, Reliable Chimney Cap & Crown Across Redmond
Chimney crown repair in Redmond typically runs $380–$920, while custom cap installation ranges from $450–$1,200 depending on chase dimensions and material. Most Redmond homeowners get same-week scheduling, with our crew often reaching Education Hill, Overlake, and Grass Lawn within 24–48 hours of your call. If you’re seeing white efflorescence stains on your chase, water pooling in your firebox, or hearing dripping behind the damper during Redmond’s relentless fall rains, the crown or cap is usually the culprit — and waiting only drives the repair cost higher.
We’ve been climbing Redmond roofs since before the light rail expansion, and we know the housing stock here inside out. From the 1988–1996 prefab ranches on Education Hill to the custom builds creeping up Novelty Hill in 98053, Redmond’s mix of aging factory-built fireplaces and persistent Sammamish Valley moisture creates a specific pattern of crown and cap failures that generalist contractors routinely misdiagnose. Our Chimney Cap & Crown team doesn’t guess — we’ve replaced enough cracked crowns on Heatilator and Heat-N-Glo units in the 98052 ZIP to spot the warning signs before water ruins your firebox. Call (866) 541-8697 and we’ll get you on the schedule.
Why Horizon Chimney Sweep Washington Is Redmond’s Preferred Chimney Cap & Crown Company
James Wilson still carries his tools to jobs in Redmond — he’s not sitting in a Seattle office dispatching subcontractors. When you book a crown inspection in the 98052 or 98053 ZIP codes, you’re getting 17 years of chimney-only diagnostic experience at your door, not a handyman who splits time between gutters and dryer vents. That matters in Redmond, where the difference between a crown coating and a full chase rebuild can save you thousands, and only someone who’s seen a thousand prefab fireplaces knows which path to take.
Our reputation here is documented, not claimed. With 1,006 verified reviews averaging 4.8 stars, we’ve earned repeat calls from Redmond homeowners who’ve learned that chimney work isn’t a commodity — it’s a craft. Many of our Redmond customers found us after a previous contractor patched a crown crack with hardware-store caulk that failed within a season. We don’t do patch jobs. We use Gelco crown coating and custom-fabricated caps from Olympia Chimney and Famco because Redmond’s rainfall demands materials that outlast the warranty.
Response time matters when water’s entering your chase. We typically schedule Redmond cap and crown work within 1–3 business days, and we keep common cap sizes and crown coating materials stocked for the chase dimensions we see most often in 1985–2000 builder-grade homes. No waiting three weeks for a part to ship while your firebox rots.
Our Chimney Cap & Crown Services in Redmond
Crown Repair
Crown repair is what we recommend when the concrete crown atop your chimney chase has developed cracks but the underlying structure remains sound. In Redmond, this scenario plays out constantly on Education Hill and in Overlake, where original uncoated concrete crowns from the 1988–1996 building boom have endured three decades of thermal cycling and Sammamish Valley moisture. We grind out the cracked concrete, apply a bonding agent, and pour new crown material with proper slope and drip edge to shed water away from your brick or siding. For prefab fireplace chases with deteriorated crown wash, we’ll assess whether the metal chase top can be salvaged or if a custom cap makes more sense. Typical crown repair in Redmond runs $380–$650 for a standard single-flue chase.
Crown Coating
Crown coating is our go-to preventive and early-intervention service for Redmond homeowners who catch crown deterioration before cracks propagate through the full thickness. We apply Gelco crown coating — a flexible, waterproof membrane that bridges hairline cracks and blocks the moisture that drives efflorescence and spalling in Redmond’s wet climate. This is especially valuable for the brick chimneys in downtown Redmond’s original townsite and for prefab chases in Grass Lawn where the factory crown wash is starting to map-crack but hasn’t failed structurally. Crown coating in Redmond typically costs $280–$480 and adds 10–15 years of service life to a crown that’s otherwise on borrowed time.
Custom Cap Installation
Custom caps solve the problems that off-the-shelf products can’t touch. In Redmond’s 98053 Novelty Hill corridor, where 2000s custom homes often feature gas inserts in decorative masonry chases, standard galvanized caps look wrong and fit worse. We fabricate and install custom caps in copper, stainless steel, and powder-coated steel to exact chase dimensions, with proper screening to keep out the birds and squirrels that plague Redmond’s wooded lots. A custom copper cap on a prefab chase in Overlake or Education Hill doesn’t just seal out moisture — it outlasts the original factory components by decades. Custom cap installation in Redmond ranges from $650–$1,200 depending on metal choice, chase height, and whether we need to extend or modify the flue termination.
Cap Replacement
Cap replacement is straightforward until it isn’t. In Redmond, we replace dozens of rusted-through galvanized chase covers every year on the 1985–2000 builder-grade homes that dominate the market. The factory caps on Heatilator and Heat-N-Glo prefab units from that era were never designed for 30+ years of Redmond rainfall, and once they rust through, water enters the chase and accelerates every other failure mode. We stock replacement caps in common sizes for the chase dimensions we see repeatedly in 98052, and when we don’t have the exact fit, we measure and order from Famco or Copperfield with minimal delay. Standard cap replacement in Redmond runs $320–$580 installed.

Trusted Brands We Service in Redmond
We install and repair with materials from Gelco, Olympia Chimney, and Famco — brands we’ve specified for years because they hold up to Redmond’s specific abuse. Gelco’s crown coating remains flexible in cold weather, which matters when your crown is taking December rain at 40 degrees. Olympia Chimney’s stainless chase covers outlast the galvanized originals by a factor of three. We keep common sizes in stock for Redmond’s prevalent chase dimensions, so most cap replacements don’t involve a two-week wait. When a custom fabrication is called for — say, a copper cap for a Novelty Hill home where the homeowner wants the chase top to complement the roofline — we measure, cut, and install on-site rather than ordering a generic approximation.
Common Chimney Cap & Crown Problems We See in Redmond Homes
- Hairline crown cracks on 1988–1996 Heatilator units. In Education Hill and Overlake, prefab fireplaces from this era develop thermal-cycle cracks in the crown wash that allow moisture to wick directly into the chase. The cracks are often invisible from ground level and only reveal themselves during a rooftop inspection — by which point refractory panel damage is frequently underway.
- Moss-driven crown spalling on brick chimneys in 98052. Redmond’s position at the Cascade foothills means more fog and persistent moisture than Seattle or Bellevue. Brick chimneys in the Sammamish Valley fog zone accumulate moss that holds water against the crown, accelerating freeze-thaw spalling and efflorescence far faster than in drier Eastside microclimates.
- Rusted factory chase covers on builder-grade homes. The galvanized steel caps installed on 1985–2000 Redmond ranches and colonials were rated for 15–20 years in moderate climates. After 25–40 years of Redmond rainfall, they’re perforated, sagging, or completely detached — and every rainy season without replacement risks firebox and damper corrosion.
- Improperly sloped crowns pooling water. Original crowns on downtown Redmond’s 1960s–70s brick chimneys and on some prefab chases were poured flat or reverse-sloped. In a city that receives 40+ inches of annual rainfall, a flat crown is a failed crown waiting to happen. We re-pour with minimum 3:12 slope and drip edge as standard.
Pricing for Chimney Cap & Crown in Redmond, WA

|---|---|---|
| Crown Coating (preventive) | $280–$480 | Chase size, crack extent, accessibility |

These ranges reflect what we actually charge Redmond homeowners — not national averages or bait-and-switch estimates. A ranch on Education Hill with a single flue and easy roof access sits at the lower end. A steep-pitch custom home in 98053 with a chase that needs scaffolding and a fabricated copper cap lands higher. Every estimate we provide is free, in-person, and itemized. We don’t quote over the phone for crown work because the difference between a coating and a rebuild isn’t visible from the driveway. Call (866) 541-8697 to schedule your free inspection.

FAQs — Chimney Cap & Crown in Redmond
You’ll likely need crown coating or partial rebuild rather than simple patching — factory crown wash on 1992 Heat-N-Glo units in Redmond is typically degraded beyond what caulk or sealant can address. We inspect the crown thickness, check for moisture intrusion into the chase, and assess refractory panel condition before recommending coating ($280–$480) or rebuild ($380–$650). Call (866) 541-8697 for a free inspection — estimates are free.
Education Hill’s 1988–1996 homes share original factory-built crowns that weren’t designed for 30+ years of Redmond’s rainfall and thermal cycling, while newer neighborhoods have crowns with modern formulations and proper slope. The Sammamish Valley fog accelerates deterioration on these older units. We see this pattern so consistently in 98052 that we proactively check crown condition on every Education Hill service call. Call (866) 541-8697 for a free inspection — estimates are free.
Yes, if your Overlake home has two flues terminating in a single chase — a multi-flue cap provides unified protection with proper spacing and screening for both flues. Single caps on dual-flue chases leave gaps where Redmond’s driving rain enters, and they’re more prone to wind displacement. Multi-flue cap installation in Overlake typically runs $520–$890. Call (866) 541-8697 for exact measurements — estimates are free.
We can repair or replace the crown independently if the brick courses below remain structurally sound, but spalling near the crown often indicates that moisture has penetrated beyond the crown interface. We inspect the upper brick courses and mortar joints before recommending crown-only repair ($380–$650) versus more extensive masonry work. Downtown Redmond’s 1970s brick frequently needs repointing in addition to crown work. Call (866) 541-8697 for a free inspection — estimates are free.
A properly fabricated copper custom cap will block direct rainfall and shed water away from your chase, but it won’t fix an already-compromised crown or chase structure beneath it. For Novelty Hill prefab units with sound crowns, a copper cap provides decades of protection; if the crown is cracked, we repair first, then cap. Custom copper cap installation in 98053 typically runs $850–$1,200. Call (866) 541-8697 for a free inspection — estimates are free.
We serviced a ranch-style home on 156th Ave NE in the Overlake neighborhood where the original Heatilator prefab fireplace had a deteriorated crown that allowed moisture to wick into the chase, causing efflorescence. We installed a custom copper cap and applied Gelco crown coating to seal the cracked concrete crown, preventing further spalling. That homeowner’s neighbor called us three months later with the same house model and the same failure — we’d already seen it before.
