Chimney Cap & Damper Installation Experts in New Haven, CT

A well-installed cap and damper are the first lines of defense against water, debris, and unwanted pests. At New Haven Chimney Masters, we install high-quality stainless steel caps and precision-sealing dampers that protect your chimney from the elements while improving your home’s energy efficiency.

Why Chimney Caps Matter

Chimney caps are designed to sit at the top of your flue, acting as a weatherproof shield. Without a cap, rainwater can enter the flue, leading to rusted dampers, cracked tiles, mold growth, and odors. Caps also prevent birds, squirrels, and leaves from nesting inside the chimney—common issues we see across New Haven, CT homes.

• Prevents rain and snow from entering the flue.
• Keeps out animals, debris, and leaves.
• Blocks sparks and embers from escaping to the roof.
• Reduces downdrafts and wind-related smoke issues.

Energy-Saving Top-Mount Dampers

Traditional throat dampers often rust and fail to close tightly, allowing warm air to escape and cold drafts to enter. We install top-mount dampers that seal at the flue top with a silicone gasket for an airtight closure—improving energy efficiency and eliminating drafts. They also double as rain covers, giving you dual protection in one system.

Our Installation Process

1. Inspection: We inspect the flue opening and measure for precise cap or damper fit.
2. Recommendation: Choose from stainless, copper, or custom powder-coated finishes.
3. Installation: Secure cap or damper with corrosion-resistant anchors and weatherproof sealant.
