Fast, Reliable Chimney Cap & Crown Across Aloha
Chimney cap and crown repair in Aloha typically runs $280–$650 for most jobs, with same-week scheduling available throughout the 97003 area. We’re familiar with the ranch and split-level tract homes that dominate this unincorporated Washington County community, and we make the drive from our Seattle base with the right materials already loaded — because Aloha’s 1970s-era masonry chimneys don’t need guesswork, they need someone who’s seen this exact housing stock before. Call (866) 541-8697 for a free estimate.
Our Chimney Cap & Crown team has worked on hundreds of chimneys in the Tualatin Valley, and we’ve learned that Aloha’s conditions create specific failure patterns you won’t find in drier eastern Oregon or newer suburban developments. The long rainy season, the aging clay flue tiles, the unincorporated permitting situation — these aren’t footnotes. They’re the reason your crown cracked or your cap rusted through in the first place.
Why Horizon Chimney Sweep Washington Is Aloha’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Aloha one chimney at a time. Our 1,006 verified customer reviews averaging 4.8 stars include plenty from Washington County homeowners who found us after a bad experience with a generalist contractor who treated their masonry chase like a roof repair.
James Wilson, our owner and lead technician, has spent 17 years focused exclusively on chimneys — not roofing, not HVAC, not handyman work. When he arrives at your door in Aloha, you’re getting hands-on expertise from someone who has diagnosed thousands of crown failures and cap installations. Not a subcontractor learning on your dime.
Response time to Aloha is typically 3–5 business days for standard cap and crown work, with emergency appointments available when water is actively entering the flue. We know the area: SW Johnson Street, the neighborhoods near Cooper Mountain, the acreage properties off SW 185th. That local familiarity means we arrive with the right crown coating material, the correct cap size, and realistic expectations about what Washington County will require for permits.
Here’s what separates us in Aloha specifically: we understand the permitting trap. Because Aloha is unincorporated, chimney cap replacements and crown repairs require Washington County Building Department permits — not city permits. Contractors from Beaverton or Portland routinely miss this, leaving homeowners with unpermitted work that surfaces during resale inspections. We’ve navigated this jurisdictional quirk dozens of times.
Our Chimney Cap & Crown Services in Aloha
Crown Repair
Crown repair in Aloha runs $320–$580 and addresses the concrete or mortar wash that tops your masonry chimney. We’ve rebuilt dozens of crowns on 1970s ranch homes near Cooper Mountain and throughout the 97003 zip code where decades of Tualatin Valley moisture have caused the concrete to crack and spall. The original construction surge of the 1980s left many Aloha homes with improperly sloped crowns that pool water instead of shedding it — a design flaw we correct by reforming the crown with proper pitch and overhang. Our crown repairs use industry-standard materials designed to withstand the freeze-thaw cycles that hit harder here than in drier parts of Oregon.
Crown Coating
For crowns with minor cracking but sound structural integrity, crown coating in Aloha costs $280–$420 and adds 10–15 years of waterproof protection. We apply Gelco crown coating — a flexible, breathable sealant that bridges hairline cracks while allowing trapped moisture to escape. This is particularly valuable in Aloha’s climate, where persistent fall-through-spring rainfall keeps masonry saturated for months. We’ve applied crown coating to chimneys off SW Johnson Street and throughout the older split-level neighborhoods where homeowners want to stop water intrusion without the cost of full crown rebuild. The coating cures to a finish that sheds water rather than absorbing it, which matters when your chimney faces six wet months annually.
Multi-Flue Cap Installation
Multi-flue cap installation in Aloha ranges from $450–$750 depending on chimney dimensions and access. Many Aloha homes — especially the larger split-levels and early colonials built in the late 1980s — have multiple flues sharing a single chimney chase: one for the fireplace, one for a furnace or water heater vent. A single multi-flue cap protects all flues with one properly sized cover, eliminating the gaps between individual caps where water and debris enter. We source multi-flue caps from Olympia Chimney and Famco, sized precisely to your chase dimensions. This matters in Aloha because the aging clay flue tiles common in local masonry chimneys need protection from water infiltration that accelerates spalling and liner deterioration.
Cap Replacement
Standard cap replacement in Aloha costs $180–$340 for single-flue galvanized or stainless steel units. We see the most replacement need on original caps from the 1970s and 1980s building boom — galvanized caps that have finally rusted through after 40+ years of Tualatin Valley moisture exposure. We stock stainless steel and copper options from Gelco and Copperfield that outlast the originals by decades. For Aloha homeowners with detached workshops or accessory buildings that have chimney-equipped wood stoves, we assess whether your usage pattern and flue size warrant a heavier-duty cap than the original builder installed.

Trusted Brands We Service in Aloha
We install and repair using Gelco, Olympia Chimney, and Famco caps and components — brands we’ve specified for years because they hold up to Aloha’s wet climate. Gelco’s stainless multi-flue caps and crown coating products are our go-to for moisture protection in the Tualatin Valley. Olympia Chimney’s galvanized and stainless single-flue caps match the sizing common to 1970s tract home construction here. We keep common sizes in stock, which means most Aloha cap replacements don’t require a two-week order delay. When we quote your job, we’re quoting with the actual part we’ll install, not a placeholder we’ll swap for whatever’s cheapest.
Common Chimney Cap & Crown Problems We See in Aloha Homes
- Corroded original caps on 1970s masonry chimneys. The galvanized caps installed during Aloha’s original building boom have reached end of life. We’ve replaced dozens on ranch homes near SW 185th where rust holes allowed water straight onto the crown below, accelerating concrete spalling that could have been prevented with timely replacement.
- Crown pooling from improper original slope. Unpermitted crown repairs during the 1980s surge left many Aloha homes with flat or reverse-sloped crowns that collect water. In our freeze-thaw climate, that pooled water expands and contracts until the crown crumbles. We rebuild with minimum 3/4-inch per foot pitch to shed water properly.
- Moisture-damaged mortar joints on exterior chimney chases. The Tualatin Valley’s eight-month wet season keeps masonry saturated far longer than in Bend or eastern Oregon. We’ve repointed chimney faces on split-levels throughout 97003 where cap failure allowed water to wick down through open mortar beds, undermining structural integrity.
- Multi-flue gaps on homes with multiple heating appliances. Older Aloha properties often have fireplace and utility flues in the same chase with poorly fitted individual caps. The resulting gaps admit rain, leaves from mature neighborhood trees, and the occasional bird nest. A properly sized multi-flue cap from Olympia Chimney eliminates these entry points entirely.

FAQs — Chimney Cap & Crown in Aloha
Yes — chimney cap and crown work in Aloha requires Washington County Building Department permits, not city permits. Because Aloha is unincorporated, contractors accustomed to Beaverton or Portland city permitting often miss this requirement, leaving homeowners with unpermitted work that complicates resale. We file Washington County permits as standard practice for all cap and crown projects in 97003. Call (866) 541-8697 and we’ll confirm whether your specific project needs permitting.
Aloha’s extended rainy season — typically October through May — keeps masonry saturated for eight months annually, accelerating freeze-thaw damage and mortar deterioration. The Tualatin Valley’s mild, wet winters mean more fireplace use while firewood remains damp, producing cooler, slower burns that deposit acidic condensation on crown surfaces. We’ve rebuilt crowns in Aloha that showed 20 years of equivalent wear in just 8–10 years of actual service. An annual inspection catches crown deterioration before water enters the flue system.
A multi-flue cap provides excellent protection for aging clay flue tiles by preventing the water infiltration that causes spalling and liner failure. Many Aloha homes built in the 1970s and 1980s retain original clay-tile-lined masonry chimneys that have never been relined — now 40–50 years old and increasingly brittle. The multi-flue cap shields these tiles from direct rain and reduces thermal shock from sudden temperature changes. We assess flue tile condition during every cap installation and flag deterioration that warrants liner evaluation.
Standard caps work fine for most workshop chimneys, but we evaluate the specific conditions. On Aloha acreage properties with detached shops, heavy-duty door operation can create vibration and air pressure changes that stress chimney structures — especially if the flue is close to the door track. We specify appropriately sized caps with secure mounting brackets and assess whether the chimney chase itself needs reinforcement. During our free estimate, we’ll measure clearances and recommend the right cap for your setup. Call (866) 541-8697 to schedule.
Crown coating and resealing typically does not require a permit in Washington County if no structural modification occurs — but crown rebuilds and cap replacements generally do. The distinction matters because unpermitted structural work can surface during home resale inspections, especially in Aloha’s unincorporated jurisdiction where records are centrally filed with the county. We clarify permit requirements before starting any work and handle all applications when permits are needed. For a definitive answer on your specific project, call (866) 541-8697 for a free evaluation.
On a ranch split-level off SW Johnson Street, we replaced a corroded multi-flue cap from Olympia Chimney that had allowed rainwater to crumble the crown on a 1970s masonry chimney. Our crew applied a Gelco crown coating to seal the rebuilt crown, ensuring the structure withstands Aloha’s long rainy season.
