How Do I Replace My Fireplace Door Gasket?

Due to the normal wear and tear that comes from opening and closing your fireplace door, gaskets will need to be replaced when they are no longer establishing a firm seal. The good news is, this is an easy DIY task that can be completed in a very short amount of time, right in your own home. (For a complete tutorial on how to test your high temperature gasket first, click here to be redirected to an instructional video!) 

Just a friendly suggestion: it is a good idea to replace the window seal along with the door gasket.

  • disposable gloves*
  • safety goggles*
  • flat head screwdriver
  • wire brush
  • small vacuum or shop-vac
  • new gasket
  • gasket cement* (available in a tube or caulk-gun cartridge)
  • heavy duty scissors
  • caulking gun
  • damp cloth

*Gasket cement can cause skin and eye irritation! Protect yourself when using this material.

  1. Carefully remove the fireplace door and place it on a soft padded surface. Seek out some help from a friend if your door is heavy.
  2. Using your screwdriver, pry out and remove the old gasket.
  3. Thoroughly clean out the channel, making sure to remove all the old adhesive with a wire brush. After this is complete, clear the channel of any dust with a small vacuum or shop-vac.
  4. Try in the new gasket. Determine the appropriate length and then cut the gasket with the heavy duty scissors.
    • If using a tube cement application, squeeze it a few times to ensure the cement is evenly distributed.
    • If using a cartridge, shake well before cutting the nozzle to the desired opening. Insert into a standard caulking gun, then gently squeeze the handle to apply an even bead of adhesive into the channel. 
  5. Apply the adhesive cement into the door channel. 
  6. Press the new gasket firmly into the adhesive. The gasket will need to be bonded at both ends where the butt joint is made. 
  7. Remove any excess cement with a damp cloth before it dries. 
  8. Replace and close the fireplace door.
  9. Allow the adhesive to dry thoroughly overnight before exposing the cement to heat. When you do ignite a fire, gradually increase the heat to initiate the final cure of the adhesive.

Although your glass window gasket doesn't undergo the same compression forces as your door gasket does, you can replace it at the first signs of fraying or unraveling material. However, as a good rule of thumb and to avoid oversights of the seal's condition, it is recommended that you replace the window gasket simultaneously with the door seal.
