Though a small component, your chimney cap performs a colossal job: it vigilantly keeps rain, snow, bothersome birds, curious squirrels, and dangerous stray embers out of your flue. An open or absent chimney cap is the leading cause of preventable chimney water damage and animal nesting in Renton homes. We accurately measure your flue and install a robust, corrosion-resistant stainless-steel cap—available for single or multi-flue systems—complete with animal-guard mesh and hardware specifically engineered to endure the variable Pacific Northwest weather.
For Renton homes situated near the Cedar River or Lake Washington, the combination of high Pacific Northwest winds and relentless rain makes a properly sealed, corrosion-resistant chimney cap absolutely essential to prevent water intrusion and animal access.

Why it matters
An open flue is essentially an open door for rain, snow, birds, and squirrels to enter your chimney system – and a dangerous pathway for stray embers to escape and land on your roof. Water infiltration through an uncapped flue leads to rusted dampers, saturated masonry, and a significantly shortened liner lifespan. Meanwhile, nesting animals can dangerously obstruct the flue, forcing carbon monoxide back into your home. A properly installed cap, complete with a spark-arrestor screen, effectively resolves all these critical issues at once.
If any of these sound familiar, it's worth a free inspection:
See the difference
The before is an open flue with nothing over it — wide open to rain, snow, leaves and nesting animals. The after carries a stainless cap with spark-arrestor mesh. The cap keeps water out of the flue (the single biggest driver of interior chimney decay) and stops birds, squirrels and embers, for very little cost relative to the damage it prevents.
A wide-open flue capped in stainless — the rain and the squirrels stay out.
Representative example of a typical chimney cap installation — not a specific customer job. We add photos of our own completed the Eastside projects as we finish them.
A common find down in Kennydale: an open, capless flue with water stains inside the firebox and a bird nest starting up top. An uncapped flue is an open drain into the middle of the chimney — rain, damp and animals all take the invitation. We fit a stainless cap with spark-arrestor mesh, sized to the flue. Small part, quick job, and it heads off the water damage that costs real money later.
