Custom Chimney Caps on Long Island

A chimney cap is one of the most important and most overlooked components of your chimney system. This simple device, mounted at the top of the flue, provides protection against water, animals, debris, and downdrafts. Yet many Long Island homes have either no chimney cap at all or a cheap, ill-fitting cap that isn't doing its job.

At Capstone Chimney, we specialize in custom-fabricated chimney caps designed and fitted specifically for your chimney. Unlike off-the-shelf caps that come in limited standard sizes, our custom caps are measured, designed, and built to your exact chimney dimensions.

We fabricate our caps from heavy-gauge 304 stainless steel or copper, both of which resist Long Island's corrosive salt air environment. Our stainless steel caps can be powder-coated in black or custom colors to match your home's aesthetic.

Copper chimney caps are a popular upgrade for Long Island homeowners who want a premium, distinctive look. Over time, copper develops a beautiful green patina that adds character and elegance. Copper caps are especially popular on homes with copper gutters, Colonial architecture, and waterfront properties.

Every custom cap includes a mesh spark screen that meets code requirements while providing maximum airflow. The mesh prevents animals from entering, stops sparks from reaching your roof, and reduces wind-induced downdraft without restricting the draft your fireplace needs.

Multi-flue caps are available for chimneys with two or more flues. These single-piece caps cover the entire chimney crown, providing superior weather protection for the crown surface while capping all flues with one elegant installation.

All Capstone Chimney custom caps are installed with stainless steel fasteners and high-temperature sealant for a secure, permanent mount that will stand up to Long Island's strongest nor'easters.
