Why Hearthstone Chimney Co. Is Des Moines’s Preferred Chimney Cap & Crown Company
We’ve worked on chimneys in Des Moines long enough to recognize the neighborhoods without checking a map. The mid-century ranches clustered near Woodmont Beach, the split-levels climbing the hillside toward Zenith, the older waterfront properties along the marina - each has chimney characteristics we’ve documented over decades. Our Level-2 camera inspections end with photos you can see and a plain-English verdict, documented like an engineer, explained like a craftsman.
Des Moines homeowners have left us reviews mentioning specifically that we showed up when we said we would and explained the repair before touching anything. We’re not a one-truck operator who might answer the phone next year, and we’re not a chain sending whoever’s available from Tacoma. Our Chimney Cap & Crown in Des Moines crew arrives in uniform, background-checked, with the parts and materials to finish most cap and crown jobs in one trip.
Response time to Des Moines is same-day or next-day for standard calls, and we keep emergency slots open because a failed crown during a November storm doesn’t wait for business hours. The live person who answers our phone at 10 PM on a Saturday has real scheduling authority - no callback queue, no app to download.
We understand the local building context: Des Moines expanded heavily as a post-WWII suburban community through the 1950s-1970s, leaving a large share of the housing stock as mid-century ranch and split-level homes - many with original masonry chimneys now 50-70 years old, clay tile flue liners, and aging mortar beds that are highly vulnerable to the area’s persistent moisture. Some older waterfront-adjacent properties predate modern chimney liner standards entirely. That history matters when we’re evaluating whether your crown needs coating or your cap needs upsizing for multiple flues.
Our Chimney Cap & Crown Services in Des Moines
Cap Installation
New chimney cap installation in Des Moines runs $280-$450 for a standard single-flue stainless steel unit, with multi-flue and custom caps ranging higher. We size caps to handle the wind fetch off Puget Sound - a cap that works inland in Kent may not stay put on a bluff-top chimney facing open water. Our technicians measure on-site and fabricate or order from professional-grade suppliers so the fit is exact. We also handle Chimney Liner & Rebuild in Des Moines when your flue condition requires coordinated work.
Cap Replacement
Rusted, wind-damaged, or improperly fitted caps are a constant find in Des Moines, especially on homes west of Marine View Drive where salt-laden air accelerates corrosion. Replacement typically costs $320-$520 including removal and proper sealing. We see too many caps that were “close enough” - gaps that let rain in, screens that clog with debris, mounts that loosen in the first winter storm. We install caps from Famco and Copperfield, brands that hold up to this environment, and we document the before condition with photos you’ll see.
Crown Repair
Crown repair in Des Moines addresses the concrete or mortar wash that seals the chimney top, and it’s where we find some of the most urgent hidden damage in this city. The constant salt-laden marine air off Puget Sound, combined with the city’s bluff-top exposures, corrodes mortar joints, spalling brick faces, and deteriorates clay tile liners faster than in inland South King County cities like Kent or Federal Way. Chimneys here need inspection not just for creosote but specifically for moisture-driven structural damage that accelerates year-round because of the Puget Sound maritime environment, even in fireplaces that see light seasonal use. Crown repair ranges $450-$780 for crack sealing, rebuilding the wash slope, and waterproofing. When the crown has failed completely, we may recommend full rebuild.
Crown Coating
Crown coating with flexible, breathable sealant - we use professional-grade formulations from HeatShield and related systems - costs $380-$650 and can add years of life to a crown that’s cracked but structurally sound. In Des Moines, this is often the right middle path for homeowners in the 50-70 year old housing stock who want to prevent water intrusion without the cost of full rebuild. We evaluate crown thickness, underlying brick condition, and slope integrity before recommending coating versus rebuild. No coating goes on over damage that needs structural repair first.

Trusted Brands We Service in Des Moines
We work exclusively with professional-grade materials: DuraFlex for liner and venting components, HeatShield for crown and flue resurfacing, Famco and Copperfield for caps and termination hardware, Gelco for specialty finishes, and Olympia Chimney for structural rebuilds. We don’t substitute builder-grade alternatives to shave cost. For Des Moines customers, this means we stock common cap sizes and crown repair materials for faster turnaround - most jobs complete in a single visit because the right parts are on the truck, not on order from a warehouse three states away.
Common Chimney Cap & Crown Problems We See in Des Moines Homes
- Wind-driven rain saturation on water-facing chimney faces. Homes along the western bluff edge near the Des Moines Marina face direct Puget Sound wind fetch; chimney technicians routinely find wind-driven rain has saturated mortar and cracked crowns on the water-facing side of the chimney stack even when the interior flue looks relatively clean - making crown sealing and properly fitted chimney caps a near-universal upsell in this zip code.
- Accelerated metal corrosion from salt air. The marine layer that rolls in off the Sound carries chloride that pits and rusts galvanized and thin-gauge stainless caps within 5-8 years, versus 12-15 years inland. We see this pattern consistently in Des Moines and rarely in Tukwila or Kent.
- Crown wash erosion from freeze-thaw cycling in persistent damp. The Pacific Northwest marine climate delivers roughly 37-38 inches of annual rainfall with overcast, humid winters. Even without hard freezes, saturated crown concrete undergoes slow dissolution and surface spalling that opens cracks for deeper water penetration.
- Improper original construction on mid-century homes. Many Des Moines chimneys were built with flat or reverse-sloped crowns, no drip edge, and no expansion joint - design flaws that guarantee premature failure. We correct these with proper slope, overhang, and material specification.
Pricing for Chimney Cap & Crown in Des Moines, WA

What moves the number: accessibility (steep roof pitch, height, proximity to the bluff edge), extent of hidden water damage beneath the crown, whether flue liner repair is needed concurrently, and material choice.
