Upgrading Your Chimney to a Top Mount Damper

Updated: Dec 29, 2023

A Sustainable Solution for Fireplace Efficiency

Fireplaces, revered for their warmth and charm, have long been cherished in homes, but their conventional dampers can often be a source of inefficiency and environmental concern. The shift from an old-style fireplace damper to a modern top mount damper isn’t just an upgrade—it’s a step towards energy efficiency and environmental stewardship.

Enhanced Energy Efficiency

One of the primary benefits of replacing an old fireplace damper with a top mount alternative is improved energy efficiency. Traditional throat dampers, often located in the chimney flue, can allow significant air leakage even when closed. This constant exchange of indoor and outdoor air can lead to increased heating or cooling costs, as conditioned air escapes and drafts infiltrate the home.

Top mount dampers, on the other hand, seal the entire chimney opening when closed, effectively preventing heat loss during cold months and blocking hot air from entering during warmer seasons. By creating a tight seal, these dampers substantially reduce energy wastage, translating to tangible savings on utility bills.

Environmental Advantage: Protecting Chimneys from Wildlife Intrusion

Beyond energy savings, the installation of a top mount damper offers an environmental advantage by safeguarding chimneys against wildlife intrusion. Traditional dampers, when left open or improperly closed, can serve as entry points for animals seeking refuge or nesting spaces. Birds, squirrels, raccoons, and other creatures might find chimneys inviting, leading to potential blockages, obstructions, or damage to the chimney structure.

The utilization of a top mount damper forms an impenetrable barrier against wildlife access. Its secure closure prevents animals from burrowing, nesting, or entering the chimney, ensuring the safety of both the fireplace and the creatures that might seek shelter within.

Promoting Sustainable Practices

By opting for a top mount damper, homeowners contribute to sustainable practices and environmental conservation. Mitigating air leakage not only reduces energy consumption but also minimizes the carbon footprint associated with heating and cooling systems. Additionally, by discouraging animals from nesting in chimneys, this upgrade fosters a harmonious coexistence between human habitats and wildlife, promoting ecological balance.

Installation and Long-Term Benefits

The installation process of a top mount damper is relatively straightforward for professionals, providing a lasting solution with minimal maintenance requirements. Unlike traditional dampers prone to corrosion and wear, top mount dampers are durable and built to withstand the elements, ensuring prolonged efficiency and functionality.


Transitioning from an old fireplace damper to a top mount damper isn’t just a home improvement; it’s a conscientious choice toward energy efficiency and environmental preservation. This upgrade offers tangible benefits, from reduced energy costs to protecting chimneys against wildlife intrusion, while promoting sustainable practices for a greener future. As homeowners seek ways to enhance their homes’ efficiency and reduce their ecological impact, the installation of a top mount damper stands out as an eco-friendly and pragmatic solution.
