Replace Fireplace Damper with a New Top Mount Damper

A Top Mount Damper is a highly effective alternative to traditional throat dampers for masonry chimneys. Installed at the top of the chimney flue, these dampers create an airtight seal to block drafts, odors, and moisture from entering your home. They are particularly beneficial for chimneys with missing or deteriorated throat dampers that no longer perform efficiently.

At Nexus Chimney Services, we provide professional installation of top mount dampers, including Seal Tight, Lymance, and Spring Loaded Energy Top Dampers, tailored to your chimney’s specific needs.

Why Choose a Top Mount Damper?

1. Superior Seal

Unlike traditional throat dampers, top mount dampers seal the chimney from the top, preventing cold drafts, creosote odors, and debris from entering your home.

2. Energy Efficiency

An airtight seal reduces heat loss in winter and prevents cool air from escaping in summer, leading to lower energy bills.

3. Moisture Protection

Top mount dampers double as chimney caps, preventing rain, snow, and moisture from entering the flue.

4. Improved Indoor Air Quality

By sealing the flue, top mount dampers keep out creosote odors and sooty smells that can travel into your home through the fireplace.

Types of Top Mount Dampers

1. Seal Tight or Lymance Dampers

  • Features: These dampers feature a stainless steel frame and silicone gasket for a durable and airtight seal.
  • Operation: A pull chain installed in the firebox allows for easy opening and closing of the damper.
  • Best For: Homes with creosote odors, significant drafts, or missing throat dampers.

2. Spring Loaded Energy Top Dampers

  • Features: Equipped with a spring-loaded mechanism for smooth and secure operation, these dampers are designed for energy efficiency.

  • Best For: Homeowners seeking energy savings and advanced sealing technology.
