Seal Off Fireplace Opening

I discovered this morning that the fireplace damper in the basement fireplace is pretty much rusted beyond repair.

Seal off fireplace opening.

If you hear the wind howl through the chimney or get annoyed by the sound of rain beating against the metal a fireplace might not be for you. That is where your damper seal will be installed. Remember to purchase also a few air bricks those that allow air to flow through it. I need your help advice on how to effectively seal this.

This air intake is usually visible from the inside of the fire box and resembles a small sliding door. Permanent closures in the case that you want to permanently close off the fireplace bricking up the opening with bricks and mortar is the most complete closure method. Once the bricks are purchased a row of them need to be set about twelve inches inside the opening of the fireplace. I find myself in a chilly situation.

How to block off a fireplace. While the idea of a fireplace is romantic it might be a nuisance in practice. Look up into the fireplace opening and note the shape of the opening just below the damper. Does the fireplace have a combustion air intake.

These are measured to fit the opening of your fireplace and set in the opening as a decorative sealing cover for the fireplace. I have found the best way to seal an unused fireplace flue is to install a piece of slate or thin stone on top of the unused flue tile using masonry caulk to adhere the stone. You can follow these easy steps to block off your fireplace or even to close it up completely. Cut out the pattern and put it in place to see if it fits.

Bhuvana if you are experiencing cold drafts and heat loss with the flue capped you ll need to check two things. The cold 10 degree air has been rushing through the damper hole into the basement and eventually to the upstairs kitchen etc. This way if the fireplace is ever to be used in the future the piece of stone can be removed easily without causing any damage to the flue.
