Seal Off Fireplace Opening

This air intake is usually visible from the inside of the fire box and resembles a small sliding door.

Seal off fireplace opening.

I need your help advice on how to effectively seal this. The fireplace opening needs to be measured so you have an idea of how much brick needs to be purchased to seal it. Look up into the fireplace opening and note the shape of the opening just below the damper. Eventually we heat the air and waste a ton of energy heat.

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. 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. The cold 10 degree air has been rushing through the damper hole into the basement and eventually to the upstairs kitchen etc.

Does the fireplace have a combustion air intake. Bhuvana if you are experiencing cold drafts and heat loss with the flue capped you ll need to check two things. 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. That is where your damper seal will be installed.

I discovered this morning that the fireplace damper in the basement fireplace is pretty much rusted beyond repair. These are measured to fit the opening of your fireplace and set in the opening as a decorative sealing cover for the fireplace. While the idea of a fireplace is romantic it might be a nuisance in practice. Remember to purchase also a few air bricks those that allow air to flow through it.

I find myself in a chilly situation. Cut out the pattern and put it in place to see if it fits. 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.
