Fast, Reliable Chimney Cap & Crown Across Boulevard Park

A chimney cap and crown repair in Boulevard Park typically runs $280-$650 and is finished in a single visit. Our technicians carry Olympia Chimney and Famco caps on the truck, so most Boulevard Park jobs don’t wait on parts. Call (844) 803-1545 - a live person answers, even at 11 p.m. on a Sunday.
Why Boulevard Park’s Climate Demands Serious Crown Protection
Here’s what separates Boulevard Park from drier markets: the marine moisture here doesn’t just leak in, it colonizes. Moss and lichen root into porous concrete crowns within two to three seasons, and each freeze-thaw cycle opens hairline cracks into channels that funnel water straight to the flue. We’ve pulled crowns off Boulevard Park chimneys where the rebar was rusted to half its diameter and the brick beneath had turned to sand.
The 98168 ZIP is dense with post-WWII single-family ranches and small Cape Cods built between roughly 1945 and 1970, a large share of which are now rentals with absentee ownership. Many retain original clay-tile-lined masonry chimneys that have never been relined, making flue integrity issues a near-constant finding on first-time inspections. When water breaches a failed crown, it doesn’t just damage brick - it saturates that original clay tile, accelerates creosote corrosion, and creates the exact conditions that lead to liner failure. That’s why our Chimney Liner & Rebuild in Boulevard Park crew stays busy through the wet season.
Because Boulevard Park is unincorporated King County, residents fall under Puget Sound Clean Air Agency mandatory no-burn days rather than any city-specific ordinance. During winter air-quality episodes, all wood burning is banned outright, so every usable burn day carries extra weight for households relying on fireplaces for supplemental heat. A cracked crown that forces you to shut down mid-season isn’t an inconvenience - it’s heat you can’t afford to lose.
What to Look For: Cap Problems vs. Crown Problems
Homeowners often confuse the two. The cap sits on top like a roof over your flue; the crown is the concrete slope that seals the chimney’s top course of brick. Each fails differently, and each repair has its own price and urgency.
Signs Your Cap Has Failed
Water dripping down the flue during rain. Soot-stained firebox walls even when the damper’s closed. Birds or squirrels audible in the chimney - a missing or rusted cap is an open door. In Boulevard Park, we see galvanized caps corrode through in 8-12 years because the marine air never really dries out. Stainless or copper caps from Famco last decades, but only if they’re sized correctly for multi-flue chimneys common on these older ranches.
Signs Your Crown Is Compromised
Spalling brick faces on the chimney’s top three feet. Mortar joints that wash out and recede. A crown surface that sounds hollow when tapped, indicating delamination from the brick beneath. In Boulevard Park’s rental stock, we’ve found crowns that were “repaired” with rooftop caulk or mortar mix shoved into cracks - neither bonds to concrete, neither sheds water, and both guarantee the real repair will cost more later.
Our Chimney Cap & Crown Services in Boulevard Park
Cap Installation
New cap on a flue that’s never had proper protection? We measure on-site, fabricate from Olympia Chimney or Famco stock, and install same-day for standard sizes. Boulevard Park’s prevailing winds off Puget Sound call for caps with integrated wind-resistant screening - cheaper hardware-store caps invert in a storm and become debris hazards. Our Chimney Cap & Crown team sizes for your specific flue count and chimney dimensions, not approximate guesses.
Cap Replacement
Rusted, wind-damaged, or improperly installed caps come off, flue condition gets documented with camera, and the replacement goes on with proper clearance and secure fastening. On a recent call near South 140th Street, we found a cap that had been screwed into the crown’s edge - three of four fasteners had pulled out, leaving a gap that funneled rain directly onto the firestop. Replaced with a Gelco stainless unit, caulked and counter-flashed correctly. Done right, and we stand behind it.
Crown Repair
Minor cracking, surface spalling, or edge deterioration gets addressed with professional-grade crown coating - we use HeatShield and Copperfield systems formulated for Western Washington’s wet-dry cycling, not generic hardware-store sealers that peel in two seasons. For crowns with structural cracks or significant material loss, we cut back to sound concrete, form and pour a new crown with proper slope and overhang. Most Boulevard Park crown repairs run $340-$580 and finish in one visit.
Crown Coating
Preventive maintenance for crowns showing early wear but still structurally sound. We clean the surface, repair hairline cracks, and apply a flexible, breathable coating that moves with thermal expansion without cracking. In Boulevard Park’s climate, we recommend this at year 10-15 on a new crown, or immediately after any significant repair. It’s the difference between a $280 coating and a $1,200 rebuild five years later.
Multi-Flue & Custom Caps
Many Boulevard Park ranches have dual-flue chimneys serving a fireplace and a former oil furnace or water heater. Single-flue caps leave the second flue exposed, or get jury-rigged with incompatible hardware. We fabricate and install multi-flue caps in galvanized, stainless, or copper, with custom screening and cleanout access. Custom work runs $480-$890 depending on metal and complexity - we quote upfront, and the number on the estimate is the number on the invoice.

Common Chimney Cap & Crown Problems We See in Boulevard Park Homes
- Crown wash failure on original 1950s-60s construction. Many Boulevard Park chimneys were built with a thin “wash” of mortar over the top course of brick, not a proper 4-inch reinforced concrete crown. That wash cracks within 20 years, and by the time we see it, water has saturated the top three feet of masonry. We replace with a true poured crown, sloped minimum 3/4 inch per foot.
- Galvanized cap corrosion from marine air exposure. The SeaTac lowlands never fully dry out between October and May. Galvanized steel caps in Boulevard Park typically show through-rust in 8-12 years. We upgrade to stainless or copper, with proper spark arrestor mesh that doesn’t clog with creosote.
- Improper prior repairs using non-bonding materials. Caulk, roofing tar, or standard mortar slathered over a concrete crown will not bond and will not flex. We’ve scraped gallons of this off Boulevard Park chimneys, each layer hiding worse damage beneath. The right repair starts with removal, not cover-up.
- Multi-flue chimneys with partial or missing coverage. Rental properties especially often have one failed cap removed and never replaced, leaving the flue open to water, animals, and debris. Our inspection documents the condition with photos you can see, and a plain-English verdict on what’s urgent versus what can wait.
