Sealing your ash dump door is an effective way to improve energy efficiency, prevent drafts and odors in your home, and ensure proper ventilation. To unstick the ash door from the inside, sweep loose ash off the door and away from all edges and hinges. Wire brush around the edges of the door and spray with rust spray. Dry ash can billow into dust clouds if moved too quickly, shaken, or dropped. Some ash pits tunnel ash to the basement, making cleanup difficult. Others direct the fireplace ash to an outside door for easier cleanup.
To maintain a clean fireplace ash dump, clean the surfaces of loose rust and dirt, then wipe them clean of remaining dust before applying high-temperature silicone exterior grade. The exterior cleanout door and the ash dump door should be bRICK over both the exterior cleanout door and the ash dump door in the bottom of the fireplace. They allow you to sweep ashes into an ash pit located through the doors under your fireplace.
Due to intense heat and corrosion damage, ash dump doors need frequent cleaning. For the door, consider chiseling it out, getting a concrete block, and patching it in with mortar. If an outside ash dump on a masonry fireplace, seal it with a closed cell foam weatherstrip.
Try stuffing the ash pit opening with fiberglass insulation (remove plastic or paper) tightly and see if the furnace continues to draw the smell. You could also remove the ash pit opening and replace it with a firebrick and mortar it back in. Adjust the design of the hearth and seal off the ash dump.
A self-sealing ash dump with a spring-loaded trap door provides a time-saving, hassle-free ash removal solution. Install a Flueblocker or Chimney Balloon as low as possible in the flue to seal much of the smell outside. Ash pits are designed to deter smokey smells.

Hi! So glad I found this article! I have a question. We have a fireplace but we don’t have any type of access door to the chimney for the ash pit. Our home is on a slab foundation and when I look down into the ash pit, it seems to go deep into the ground. Is there something I should be looking for as far as a door or some type of entryway in order to clean out the ash pit? Or will my ash pit have to be clean a different way since we have a slab foundation?

Hey Mike, this is off topic but how long can I expect a chimney to last? Our cabin was built in 1907. I say keep pointing it and make it last. Some family members want to tear it down. It’s a fireplace with no flue liner—just bricks. I’m not even sure it’s ever been properly cleaned. Thanks. I enjoy your articles.

I have a 3-flue chimney at my house. And one day I heard banging in the basement. I went downstairs and found a squirrel running around down there. He apparently came down one of the flues and exited into the cellar because the latch wasn’t working on one of the flue clean out doors. I have since put a chimney cap over the entire chimney and have barricaded the clean out door with an old piece of cement concrete pier. End of the squirrel problem.
