We’re across the river in Vancouver, but we make the run to Hillsboro regularly — usually same-day or next-day for cap and crown calls. We know the difference between a 1950s farmhouse off TV Highway with a traditional masonry crown and a 2001 prefab unit in the Ronler Acres subdivision with a rusted sheet-metal assembly. That local housing knowledge saves you time. Call (888) 916-8797 for a free estimate.
Why Sequoia Chimney Sweep Vancouver Is Hillsboro’s Preferred Chimney Cap & Crown Company
Fourteen years in the chimney trade means we’ve worked on hundreds of caps and crowns across Washington County. Our 664 verified reviews at 4.8 stars include plenty from Hillsboro homeowners who found us after a generalist handyman couldn’t source the right part for their prefab flue.
Larry Peterson shows up personally. He’s the owner and lead technician — not a subcontractor rotating through from Portland. When you call about a rusted crown in the 97124 corridor, Larry’s the one who climbs the ladder, measures the flue termination, and decides whether a DuraFlex multi-flue cap or a custom-fabricated solution is the right fit.
We stock HeatShield crown coating, Gelco stainless caps, and Famco custom hardware on our service trucks. For Hillsboro’s Intel-era tract homes with odd-shaped prefab terminations, that inventory means we don’t leave you waiting while parts ship from a warehouse.
Our Chimney Cap & Crown Services in Hillsboro
Custom Cap Fabrication
Standard off-the-shelf caps won’t fit the irregular flue terminations common in early-2000s prefab fireplaces throughout north Hillsboro. We’ve measured and fabricated custom caps for units in the Orenco Station area, the Jones Farm vicinity, and the subdivisions off 185th Avenue where factory-built fireplaces terminate in everything from oval collars to rectangular chase pans. Larry brings a brake, shears, and copper or stainless stock to shape a cap that seats properly — no bypass gaps, no spark escape, no second appointment.
Crown Repair
Traditional masonry crowns on older Hillsboro homes in 97123 — the farmhouses and mid-century ranchers south of Main Street — crack from freeze-thaw cycles and Portland cement shrinkage. We grind out deteriorated concrete, pour a proper cast-in-place crown with adequate overhang and drip edge, or apply HeatShield crown coating when the substrate is sound but the surface is porous. Either way, water stops pooling on the smoke shelf.
Multi-Flue Cap Installation
Some of the larger homes built during Intel’s heaviest hiring waves have two or more prefab flues ganged into a single chase. A multi-flue cap from DuraFlex covers the entire assembly with one welded stainless unit, eliminating the leak paths between individual caps. We size and install these in one trip, with spark arrestors that meet Washington County fire code.
Crown Coating
For masonry chimneys with crowns that are structurally intact but weathered, HeatShield crown coating adds a waterproof, flexible membrane rated to 2400°F. It’s a cost-effective alternative to full crown replacement on Hillsboro’s older brick chimneys, especially in the central neighborhoods where homeowners want to preserve original character without the expense of teardown and rebuild.
Cap Replacement
When the original cap is missing, wind-damaged, or rusted through, we replace with properly sized stainless steel or copper. On prefab units, this often means sourcing manufacturer-specific termination collars or adapting a universal cap to an obsolete flue design. We’ve replaced caps on Heatilator, Superior, and Lennox factory-built units common in Hillsboro’s 97124 subdivisions.

Trusted Brands We Service in Hillsboro
We work with professional-grade product lines that hold up in Hillsboro’s wet winters and acidic creosote conditions: Olympia Chimney for stainless flue liners and termination components, Famco for custom-fabricated caps and hardware, and DuraFlex for multi-flue and specialty termination assemblies. We don’t use big-box aluminum caps that’ll rot out in five years. For the 97124 prefab homes with rusted sheet-metal crowns, we spec heavy-gauge stainless or copper — materials that survive the acidic condensation from unseasoned wood burning and the persistent moisture of Tualatin Valley winters.
Common Chimney Cap & Crown Problems We See in Hillsboro Homes
- Prefab metal crowns rusted through from acidic creosote. In the Intel-era tract homes of 97124, sheet-metal or pressed-steel crown assemblies reach end-of-life after 20–30 years of acidic condensation. We regularly find rust holes large enough to drop a pencil through, letting rainwater pour directly onto the firebox damper and accelerate refractory panel failure.
- Odd-shaped flue terminations that reject standard caps. Early-2000s prefab fireplaces in Hillsboro’s north-side subdivisions were built with proprietary chase pans and collar designs that no longer have OEM replacement parts available. Custom fabrication is often the only path to a proper seal.
- Heavy creosote from unseasoned wood burning. Hillsboro’s wet winters push residents to burn whatever’s available, and moisture-laden combustion gases produce thick, acidic creosote that eats through light-gauge metal caps in 5–7 years. We see this most in the 97124 corridor where busy tech-industry homeowners bought the house with the fireplace and never learned proper fuel management.
- Cracked masonry crowns on pre-1980 homes in 97123. The older farmhouses and ranchers south of Main Street have Portland cement crowns that weren’t mixed or sloped correctly decades ago. Water ponds, freezes, and spalls the concrete — eventually reaching the brick courses below.

What moves the needle: accessibility of the chimney, whether we’re working from a standard roof pitch or a steep two-story elevation, and whether the flue termination requires custom fabrication versus an off-the-shelf fit. Prefab units in 97124 often need extra labor to remove and replace chase siding or access panels. We quote upfront before any work starts — call (888) 916-8797 for a free, exact estimate.

FAQs — Chimney Cap & Crown in Hillsboro
We can often replace just the prefab metal crown assembly, but in practice the cap is usually compromised too. We serviced a 1998 tract home near Cornell Road and 185th Avenue where the prefab metal crown had rusted into a sieve, allowing rain to pour directly onto the firebox damper. We installed a custom-fit multi-flue cap from DuraFlex, sealed the crown with HeatShield coating, and verified the new cap’s spark arrestor met local code — completing the entire heavy-duty repair in one trip so the software-engineer homeowner could get back to work. Call (888) 916-8797 and Larry will assess whether your unit needs crown-only, cap-only, or both.
We install manufacturer-specific or custom-fabricated stainless steel caps designed for factory-built flue terminations, not masonry-style caps that’ll sit loose and leak. The 97124 prefab units often have oval collars, rectangular chase pans, or other non-standard shapes that require on-site measurement and fabrication. We carry DuraFlex multi-flue assemblies and Famco custom hardware to match. Call (888) 916-8797 for a free evaluation of your flue termination.
Yes. Hillsboro sits on the flat Tualatin Valley floor where cold-air drainage and winter inversions trap wood smoke at ground level, concentrating heavy fireplace use into non-curtailment windows and accelerating creosote loading. That acidic creosote condenses on the cap and crown, eating through metal faster than in better-ventilated areas. We recommend annual cap and crown inspection for Hillsboro homes that burn regularly during inversion season. Call (888) 916-8797 to schedule before the heavy burning period starts.
Yes, we install DuraFlex and custom-welded stainless multi-flue caps sized to cover your entire chimney top. The older farmhouses in 97123 often have two or more flues — one for the fireplace, one for a furnace or wood stove — with deteriorated individual caps that let water between the flues. A single multi-flue unit eliminates those leak paths. Call (888) 916-8797 for exact sizing and pricing.
Yes, HeatShield crown coating is one of our standard services for sound but weathered masonry crowns in the 97123 central neighborhoods. If the crown concrete is intact with no structural cracks or spalling, we clean, prime, and apply the flexible ceramic coating — typically $380–$580 versus $650–$1,200 for full rebuild. Larry will tell you honestly whether coating is appropriate or if the crown is too far gone. Call (888) 916-8797 for a free assessment.
