Expand and customize your stainless steel chimney cap system with CA 5/8 Modular Extensions from Chicagoland Fireplace & Chimney Restoration. Built for precision fit, stability, and long-term performance.


A Custom Copper Corner Chimney Cap combines distinctive craftsmanship and lasting function to protect your chimney while enhancing your home’s architectural character. Designed with precision for chimneys that feature unique corner layouts or nontraditional rooflines, this copper cap offers both performance and style. At Chicagoland Fireplace & Chimney Restoration, every copper corner cap is custom-fabricated to exact dimensions, ensuring superior protection against rain, snow, wind, and animal intrusion. The solid copper construction provides a lifetime of resilience and a naturally evolving patina that ages gracefully into a rich, weathered hue.
Corner chimneys require specialized cap designs to ensure proper water diversion and venting. Our fabrication team measures each structure precisely, creating a cap that fits flush with the chimney’s angles and contours. The unique corner layout allows water to flow away from critical masonry joints, protecting your chimney crown and flue system from erosion and freeze-thaw cracking. Each custom build balances form and function—preserving the chimney’s performance while adding an elegant copper accent that complements any roof style.
Built for Chicago’s unpredictable climate, copper corner caps excel in durability. Their hip-style slopes guide moisture away from the flue while maintaining essential ventilation to ensure your fireplace or heating appliance operates safely. The corrosion-resistant copper material won’t rust or degrade over time, making it a long-term solution that requires minimal upkeep. With every storm, wind, or temperature shift, your chimney stays protected from water infiltration and the costly damage that can follow.
Beyond performance, a copper corner chimney cap makes a visual statement. The warm metallic tones reflect craftsmanship and sophistication while blending seamlessly into the home’s exterior design. Each piece is hand-soldered with reinforced seams, smooth edging, and proportional symmetry that transforms a standard chimney into a defining architectural feature. Over time, the copper develops its natural patina—a sign of quality and authenticity that enhances your home’s overall aesthetic appeal.
Every installation performed by Chicagoland Fireplace & Chimney Restoration follows exacting standards for fit, seal, and ventilation. Our technicians secure each cap to ensure a watertight finish without restricting airflow. The result is a lasting defense against rain, pests, and drafts while improving overall efficiency and performance. From design to final installation, every step is completed with attention to detail and long-term value in mind, protecting your chimney investment for decades.
Choosing a Custom Copper Corner Chimney Cap adds both immediate curb appeal and enduring protection. Unlike aluminum or galvanized options, copper resists corrosion and enhances your property’s architectural integrity. It is the perfect choice for homeowners who want a refined, one-of-a-kind accent that stands the test of time.
