Chimney Cap & Crown in Aloha - Measured On Site, One Written Price

Fast, Reliable Chimney Cap & Crown Across Aloha

A worn or rusted chimney cap and a cracked concrete crown are the two most common entry points for water damage in Aloha homes. We’re Emberly Chimney Cleaners, and we’ve spent 16 years documenting exactly what the Tualatin Valley’s long wet season does to factory-built fireplace systems that are now decades past their rated service lives. If you’re seeing rust streaks on your siding below the cap, spalling concrete at the crown, or dampness inside the firebox, call (980) 580-8641. We’ll send a background-checked, uniformed technician to your Aloha home with a camera, a moisture gauge, and a written price before any work starts.

Why Emberly Chimney Cleaners Is Aloha’s Preferred Chimney Cap & Crown Company

Most of Aloha’s housing stock went up between 1968 and 1985, which means most of the chimneys we inspect here aren’t masonry at all. They’re factory-built, zero-clearance metal systems from brands like Heatilator and Superior, many of them original to the house and now running 40 to 50 years old. That’s a different inspection than a brick chimney on Portland’s east side. The failure modes are different, the repair parts are different, and the crown isn’t concrete over brick. It’s a metal chase top assembly that rusts through at the welds.

Our Chimney Cap & Crown team has seen thousands of these Aloha systems. We know what a 1982 Superior chase cover looks like after 42 winters of Tualatin Valley rain. We know what happens when a homeowner fires up the stove on the first cold day after the DEQ curtailment lifts. And we document everything. Clause 4 of the Haven Standard means every visit includes a camera scan and a photo record you keep. That’s not an upsell; it’s been our default since 2009.

Corrine Halstead leads our team, and she’s clear about how we operate: a written price, written scope, and written warranty before anyone picks up a tool. No flashlight-and-gone inspections. If our tech can’t show you the problem on camera, you don’t have to take our word for it.

Our Chimney Cap & Crown Services in Aloha

Here’s what we actually do for Aloha homeowners, from a quick cap replacement on a ranch off SW Kinnaman Road to a full multi-flue cap and crown rebuild in Aloha Knolls.

Cap Installation

A missing or undersized cap on an Aloha prefab fireplace lets rain pour directly into the flue, where it eats the steel liner from the inside while the metal chase top rusts from above. We install stainless steel caps sized to your specific flue tile or liner diameter, with proper screening to keep birds, squirrels, and wind-blown debris out during spring nesting season. Most cap installations in Aloha run $220 to $380 including the cap, hardware, and our photo-documented confirmation of the fit.

Cap Replacement

This is the most common job we do in Aloha, and it’s almost always on factory-built systems from the 1970s and early 1980s. The original caps on those units were galvanized steel, not stainless, and after four decades of 38 to 40 inches of annual rainfall, the welds let go. You’ll see rust streaks down the siding or across the chase top. We remove the old cap, check the flue for water damage while we’re there, and install a stainless replacement that won’t rust through again. Expect $280 to $450 for a standard replacement on a prefab unit in Aloha.

Crown Repair

On the masonry chimneys that do exist in Aloha, the concrete crown is the flat slab that seals the top of the chimney. When it cracks, water gets in and starts spalling the concrete apart under freeze-thaw cycles. On prefab metal systems, the equivalent is the chase top. We repair crowns with CrownCote, a flexible waterproof membrane that bridges small cracks and prevents further water intrusion. A crown repair in Aloha typically runs $350 to $600, depending on cracking severity and surface area. If the crown is too far gone, we’ll tell you plainly and give you a written price for a full rebuild.

Crown Coating

For Aloha homeowners whose crowns are structurally sound but showing early signs of weather wear, we apply CrownCote as a preventative seal. This is common on ranches and split-levels near SW Farmington Road where the chimney gets hit by full western exposure and the October-to-April rain does the rest. Coating typically costs $250 to $400 on a standard-size Aloha chimney and adds years before a full rebuild is needed.

Multi-Flue Cap

Homes with two flues sharing one chimney, usually a fireplace and a furnace or water heater vent, need a multi-flue cap rather than two single caps. We measure both flues, confirm clearances, and install a stainless steel multi-flue unit that spans the full crown width. In Aloha, this job runs $450 to $750 depending on chase width and flue spacing. We also handle custom caps for odd-shaped or oversized openings on older masonry chimneys using materials from Copperfield and Famco.

Custom Cap

Some Aloha chimneys, especially on 1970s split-levels with unusual chase covers or decorative shrouds, don’t fit off-the-shelf caps. We fabricate custom stainless steel caps matched to your existing flue configuration and crown dimensions. Expect $500 to $900 depending on size and complexity. All custom work is done to NFPA 211 clearances with a documented photo record on completion.

Trusted Brands We Service in Aloha

Aloha’s housing stock leans heavily on Heatilator and Superior zero-clearance fireplaces, so we keep replacement caps, chase covers, and crown sealants on hand for those systems specifically. Where a full liner or component rebuild is needed, we source from DuraFlex, Copperfield, and Famco materials through our buying network, which keeps parts pricing honest for Aloha customers. Whether it’s a 1981 Heatilator in a ranch near Cooper Mountain or a later Superior in a split-level off SW Murray Boulevard, we can usually match the parting exactly and have it installed without waiting on a special order.

Common Chimney Cap & Crown Problems We See in Aloha Homes

• Rust-through at cap weld seams. Factory-built caps from the 1970s and early 1980s were galvanized, not stainless. After 40-plus Aloha wet seasons, the welds fail and the cap starts letting water into the flue. What was a $300 cap replacement becomes a $2,000 liner job if you don’t catch it early.
• Spalling concrete crowns on older masonry chimneys. The few true brick chimneys in Aloha, mostly on custom homes and farm properties south of TV Highway, deal with years of rain absorption followed by winter freezes. The crown cracks, water pools, and the concrete surface starts flaking away.
• Cracked or missing caps on curtailment days. When DEQ Action Days restrict burning in the Tualatin Valley air shed, Aloha homeowners tend to burn hard on the days they’re allowed. A compromised cap exposes the flue to higher heat cycling and faster creosote condensation on cold metal surfaces. The cap wasn’t the original problem; the rust was. The heavy burning just accelerates it.
• Rust streaks below the cap, months after a sweep. If you’re seeing rust-colored staining on the siding or chase top even after a recent cleaning, the cap itself is the likely source. It’s corrosion runoff, not creosote, and it means water is penetrating somewhere above the flue tile. We’ll show it to you on camera before we touch anything.
