Though modest in size, your chimney cap performs a monumental task: it's the primary defense against rain, snow, birds, squirrels, and rogue embers entering your flue. An absent or compromised cap is the leading cause of water damage and animal infestations in Eastside chimneys. We'll accurately measure your flue and install a corrosion-resistant stainless-steel cap — available for single or multi-flue systems — complete with animal-guard mesh and hardware engineered to withstand the unique rigors of Pacific Northwest weather.

Near the water, the relentless lakeside wind and rain make a meticulously sealed, corrosion-resistant cap an absolute necessity for enduring the elements.

Why it matters

Why chimney cap installation matters

An open flue is an open invitation for rain, snow, birds, and squirrels to make themselves at home, and it also provides an exit path for hot embers to potentially ignite your roof. Water infiltration through an uncapped flue leads to rusted dampers, saturated masonry, and a significantly reduced liner lifespan. Meanwhile, nesting animals can dangerously obstruct the flue, risking carbon monoxide backing up into your living space. A robust cap, complete with a spark-arrestor screen, proactively addresses all these critical issues.

Signs you may need chimney cap installation

If any of these sound familiar, it's worth a free inspection:

  • No cap, or a rusted, bent, or missing one
  • Water, debris, or a musty smell inside the firebox
  • Birds, squirrels, or nesting sounds in the chimney
  • Downdrafts or animals getting into the home
  • A spark-arrestor screen that's damaged or absent

Chimney Cap Installation — before & after

The before is a flue with nothing over it at all — open to every storm, falling leaf and nesting bird our region can offer. The after wears a stainless cap with spark-arrestor mesh. Water pouring down an open flue is the single biggest driver of interior chimney decay, and a cap is about the least expensive part on the whole chimney relative to the damage it prevents.

Representative exampleTypical scenario — not a specific customer job
A common find around the north end of the lake: a capless, wide-open flue on a Kenmore home near Log Boom Park, water stains inside the firebox, and clear signs a bird has been keeping house up top. An open flue is the easiest invitation our rain and wildlife ever get. We'd typically fit a stainless cap with spark-arrestor mesh, measured to the flue. The result is a chimney that stays dry and animal-free — one small part standing in for a much larger repair later.

FAQ

Common questions about chimney cap installation

Why do I need a chimney cap?
It's essential because it effectively prevents rain, birds, and debris from entering the flue, deters unwanted animals, and critically, stops downdraft sparks from landing on your roof.
How much does a chimney cap cost installed?
A single-flue stainless cap is among the most cost-effective chimney enhancements you can make. Multi-flue and custom caps will naturally incur a higher cost. You'll receive the precise price before any installation begins.
Do chimney caps come in different sizes?
Yes, they do. We precisely measure your flue to ensure a perfect fit for either a single or multi-flue cap, guaranteeing an effective and proper seal.
Will a cap stop animals getting into my chimney?
Absolutely. Our chimney caps are equipped with animal-guard mesh specifically designed to prevent birds, squirrels, raccoons, and other critters from entering your flue.
How long does a stainless cap last?
High-quality stainless steel chimney caps are engineered for remarkable longevity, typically lasting for many decades, even when exposed to demanding wet-climate conditions.
