Do I need an air vent for my sealed-up fireplace?

Wondering whether to get an air vent for your sealed-up fireplace? As the world progresses, modern-day people are now closing their fireplaces. Most people are doing this because of the boom in what's known as internal heating features.

It is because we now know that chopping down trees for firewood harms the world. Many people would instead use heaters or air conditioning when looking for solutions.

This is a much more comfortable and more sustainable approach to warming your house. The only challenge is that if you have got a chimney, it can render all the heating features of your home pointless.

This is because cold air can still come in from outside. People have resorted to sealing up their unused fireplaces using bricks.

This is where the dilemma comes in. You have a space in the house utilised for charcoal, and other dangerous fumes, is it wise to close it up and leave it be?

This will discuss the importance of allowing it through your sealed fireplace. We will look at the cost involved, as well as the necessity of the procedure.

Is it necessary to have an air brick when blocking up a fireplace?

In any house, the structure is well dependent on the house's ability to deal with moisture. If you had a chimney, then the moisture absorbed will be different from normal once you seal the chimney.

Not to mention that all chemicals that come when burning wood have now stuck to the chimney walls. These chemicals will now mix with the moisture that is inside the ventilation system.

This mixture combined can begin to destroy a way out of the bricks used to build the chimney. The lack of airflow will form insulation and end up creating moisture.

Does it cost a lot to put a vent panel into a bricked-up fireplace?

In some cases, we could say that it is expensive to put a vent panel into a sealed-up fireplace. This depends on the kind of house that you have.

If you have got an average-sized modern house, then this procedure will not be very expensive. You will only need in most cases to seal up the bottom side of the fireplace.

If you do this well enough, then the top of the chimney will remain open thus providing a ventilation system. You will not need to insert one in this case. For some, it might be more complicated; for example, some chimneys go through many stories and end up at different parts of the house.

You may need to install a chimney cap or add a brick vent somewhere along the line in such a situation. This process requires expertise but is not very expensive.
