Chimney Cap Installation

A chimney cap is one of the simplest, most cost-effective investments a homeowner can make to protect their chimney system. Without a cap, your open flue is an invitation for rainfall, snow, leaves, and wildlife — particularly birds and raccoons — to enter the chimney. Water entering an uncapped flue accelerates rust on the damper, stains the firebox, and promotes deterioration of the liner and surrounding masonry. Best Rosedale Chimney Sweep carries and installs a full range of stainless steel and galvanized chimney caps in standard and custom sizes to fit single-flue, multi-flue, and round liner terminations.

Beyond weather protection, a properly sized cap also helps regulate draft. Caps with mesh skirts prevent downdrafts caused by wind — a common complaint among homeowners in our area where coastal winds from Jamaica Bay can create negative pressure in the flue, pushing smoke back into the living space. Our technicians will measure your flue opening precisely and recommend the right cap style for your chimney's configuration and your neighborhood's wind conditions. Installation is fast, typically completed within the same service visit as a cleaning or inspection, and the benefits last for years with minimal maintenance.
