Fireplace Inserts

Love the look of a fireplace but want more usable heat? A fireplace insert can improve comfort and efficiency—without giving up the feel of a real fire.

Fireplace insert upgrade for improved heating

Traditional open fireplaces can look great, but many homes lose heated air up the chimney. An insert is designed to help the fire burn more completely and put more heat back into the room.

What is a fireplace insert?

A fireplace insert is a heating appliance installed inside the existing firebox (masonry or factory-built). Most inserts are built from heavy steel or cast iron and use insulated glass doors and decorative trim panels to finish the look.

Why inserts are popular

Inserts can provide more controllable heat than an open fireplace, while keeping a clean, built-in appearance.

Benefits of adding an insert

  • Better heat output (turn the fireplace into a real room heater)
  • Improved efficiency vs. an open fireplace
  • Cleaner burn and more controlled airflow
  • Less heat loss up the chimney when installed correctly
  • Modern styles that keep (or improve) the look of your hearth

What we check before installation

A safe insert setup depends on the condition of the chimney and proper venting. If your flue has creosote buildup, draft issues, or damage, we’ll address that first so everything operates correctly.

  • We evaluate your existing fireplace + chimney condition and draft
  • We confirm sizing, clearances, and the right venting approach
  • We recommend insert options based on goals (heat, budget, style)
  • Installation includes proper connection to the flue system
  • Final check for safe operation and best practices for use
