Why Horizon Chimney Sweep Washington Is DuPont’s Preferred Chimney Cap & Crown Company

We’ve been climbing DuPont roofs since before Northwest Landing finished building out, and that repetition matters. James Wilson, our owner and lead technician, has 17 years of chimney-exclusive experience — he’s the one who shows up at your door in the 98327 ZIP, not a subcontractor learning on your dime.

Our track record is documented: 1,006 verified customer reviews averaging 4.8 stars. That’s not a handful of cherry-picked testimonials — it’s sustained, repeated trust from homeowners who’ve called us back year after year. In DuPont specifically, we hear from military families stationed at Joint Base Lewis-McChord who need reliable chimney work before housing inspections or between PCS moves. They can’t afford callbacks, and neither can we.

Response time to DuPont is typically under an hour from dispatch. We know the loop roads of Northwest Landing, the townhome clusters near Hoffman Hill, and the single-family streets off McNeil — no GPS fumbling, no “we’ll be there sometime Tuesday” vagueness.

Here’s what separates us from generalist handymen: we only do chimneys. That narrow focus means James Wilson can diagnose a rusted chase cover versus a deteriorated crown in minutes, and specify the right Gelco or Copperfield component without ordering the wrong part twice.

Our Chimney Cap & Crown Services in DuPont

Custom Cap Installation

Most DuPont homes never got a proper cap to begin with. The builder-grade zero-clearance fireplaces in Northwest Landing were often finished with stamped-metal chase covers that lack integrated spark arrestors or animal guards. A custom cap from Copperfield or Famco, fabricated to your chase dimensions, solves that permanently. We measure on-site, specify galvanized or stainless steel depending on your budget, and install with proper clearances for the metal flue. Custom cap installation in DuPont runs $340–$520.

Cap Replacement

When your existing chase cover has rusted through at the seams — and in DuPont’s 45–50 inches of annual rainfall, that’s typically within 10–15 years — replacement isn’t optional. Water intrusion rots firebox insulation, corrodes the metal flue, and can damage interior framing. We stock standard sizes for common Northwest Landing prefab models and can source Olympia Chimney or Gelco replacements for less common configurations. Cap replacement in DuPont typically costs $180–$340. We recently serviced a 2004 home on Palisade Boulevard in Northwest Landing where the original builder-grade chase cover had rusted through at the seam, allowing rain to soak the firebox insulation. We installed a custom-fabricated copper multi-flue cap from Copperfield that matches the home’s existing downspouts and will outlast the original by decades.

Crown Repair

Prefab chimney systems in DuPont don’t have traditional poured-concrete crowns like masonry chimneys, but they do have crown wash or termination assemblies that seal the chase top. Cracks here are invisible from the ground until water has already done damage. James Wilson inspects these with every cap service, and we repair using crown-specific materials rated for metal chase expansion and contraction. Crown repair in DuPont runs $280–$450.

Crown Coating

For zero-clearance systems with minor crown deterioration, a flexible crown coating can add 5–10 years of protection without full replacement. We use HeatShield crown coat products formulated for the wet Pacific Northwest climate — they flex with temperature swings and seal hairline cracks before water penetrates. This is particularly cost-effective for DuPont’s military rental properties where owners want preventive protection between tenant turnovers. Crown coating in DuPont costs $220–$380.

Multi-Flue Cap

Some larger DuPont homes, particularly the custom builds near Bell Hill, have multiple fireplace flues or a fireplace plus furnace vent terminating through a single chase. A multi-flue cap from Copperfield covers the entire assembly with one integrated unit, eliminating the seam gaps where individual caps fail. Multi-flue cap installation in DuPont ranges $420–$650 depending on chase dimensions and material.

Trusted Brands We Service in DuPont

We install and repair using Gelco, Olympia Chimney, Famco, and Copperfield components — brands that spec properly for factory-built systems. For DuPont homeowners, this means we don’t order generic “universal” caps that fit poorly and fail early. We stock common chase cover sizes for the prefab models prevalent in Northwest Landing, so most replacements don’t involve a two-week wait. When a custom fabrication is needed, Copperfield’s copper and stainless options integrate cleanly with DuPont’s vinyl-sided architecture while outlasting builder-grade steel by decades.

Common Chimney Cap & Crown Problems We See in DuPont Homes

• Rusted chase covers from chronic moisture exposure. DuPont’s position in the South Puget Sound lowlands means near-constant dampness October through May. The lightweight stamped-metal chase covers standard on Northwest Landing prefab systems corrode at seams and screw holes within 10–15 years, allowing direct water intrusion into the chase.
• Missing caps on zero-clearance fireplaces. Many DuPont homes were sold without proper chimney caps installed — just a bare chase top. Rain enters freely, and birds or squirrels nest in the metal flue. We find this most often in rental properties near Joint Base Lewis-McChord where maintenance history is nonexistent.
• Unsealed crown cracks on prefab termination assemblies. Unlike masonry crowns, prefab crown washes are thin and rigid. Thermal cycling opens hairline cracks that DuPont’s wet climate exploits relentlessly. By the time staining appears on interior chase walls, flue corrosion is often advanced.
• Military-rental turnover masking deferred maintenance. Property managers handling JBLM housing inventory frequently have zero records for fireplace condition. We treat every DuPont rental inspection as potentially uncovering multiple seasons of unchecked moisture damage and unswept creosote.
