We start with a thorough inspection of your existing chimney structure and flue configuration. This tells us exactly what type of cap you need—single-flue, multi-flue, or custom fabrication for unique setups.Next, we measure and select the right materials. Stainless steel for durability, copper for longevity and appearance, or galvanized steel for budget-conscious protection. Each cap includes proper screening to keep animals out while allowing proper ventilation.Installation happens quickly but carefully. We secure the cap to your chimney crown or flue tiles using the right fasteners for your specific setup. You get a cap that stays put during Long Island storms and does its job for years to come.
