Chimney Cap Installation
Essential protection for every chimney system.
A chimney cap is one of the most important safety and protection features you can add to your chimney. Installed at the very top of the flue, it keeps rain, snow, animals, and debris out—while also helping reduce downdrafts and preventing sparks from escaping onto the roof.
Without a cap, your chimney is completely exposed to the elements. Rain can flow directly into the flue, causing rust, cracked liners, mold growth, and costly interior damage. Birds and small animals often enter uncapped chimneys to nest, creating dangerous blockages and unpleasant odors.
At Northwest Chimney, we install both standard chimney caps and custom-fabricated chimney caps, ensuring your system is properly protected.
Standard Chimney Caps
Standard chimney caps are prefabricated, durable, and designed to fit common single-flue chimneys. They provide reliable protection at an affordable cost and are a great choice for homeowners with a straightforward chimney design.
-
Protects against rain, snow, and animal entry
-
Prevents sparks and embers from leaving the flue
-
Reduces downdrafts from sudden wind gusts
-
Cost-effective and code-compliant
Custom Chimney Caps
Not all chimneys are alike. Multi-flue systems, masonry chimneys with unique dimensions, or homeowners who want a cap that blends seamlessly with their home may require a custom cap.
Our custom stainless steel or copper chimney caps are built to exact measurements and designed for long-lasting performance and appearance.
-
Built to fit any chimney design (single-flue, multi-flue, or decorative)
-
Crafted from stainless steel or copper for superior durability
-
Optional powder-coated finishes for a polished look
-
Enhanced protection with extended drip edges and welded seams
Chimney Caps + Chase Covers
-
For full protection, many chimneys need both:
-
A chase cover to seal the chimney top
-
A chimney cap to cover the flue opening and stop rain, downdrafts, and animals
We install both as part of a complete system designed to keep your chimney safe, dry, and efficient.
Why Replacement Matters
A chimney without a cap is an open invitation for water damage, blockages, and fire hazards. Whether you choose a standard cap or a custom-fabricated solution, installing a properly fitted chimney cap is one of the simplest and most effective ways to protect your home and chimney system.
