Why Are Basements Cold?

Why Are Basements Cold?

You should consider yourself fortunate to have a basement in your home. For some people, however, its coldness comes off as a disadvantage, as the basement can practically become unusable. 

But have you ever wondered why they are so cold?

The main reason why basements are so cold is due to the water leaking through the concrete wall that can come from the ground floor or due to poor ventilation. Because of the greater moisture content suspended in the air, the air is much colder

This is because humidified air carries the body heat away more significantly than dry air. 

Here in this article, we will discuss more reasons why your basement is much colder than the rest of the house and what you can do about it. 

What Are the Main Reasons That Make Basements Colder? 

There are a few other reasons why basements are cold besides water leaking through the concrete wall.

Let us go through the other two explanations for the coldness in basements. 

Cold Air Is Denser

If we talk from a scientific point of view, cold air is denser than hot air. Hot air rises and is replaced by cold air in exchange.

The problem will persist even if your basement has adequate insulating material.

The basement will, without a doubt, be colder than the rest of the rooms due to its partially underground location.

Using a fan to drive cold air higher is a simple solution to this problem.

Even if you don’t own any heating fan, using a simple electric fan at the stairs will help you in removing the cold air from your basement. 

Limited Access To Direct Sunlight

Direct sunlight is beneficial for you and your home.

The direct entry of sunlight through your windows and curtains can increase the temperature of the house by up to 10 degrees even in colder seasons.

Basements are not exposed to direct sunlight. 

Sadly, this implies that your basement is not profiting from the hotness of the sun, and the high temperatures on the second floor prevent the thermostat from working properly. 

On one hand, it saves you a few pennies but in return, your basement turns colder.

Assuming you are going on a vacation and leaving your home for a lengthy amount of time during the cold season, keep in mind that the temperature in your basement is much lower compared to other parts of your home, so you should adjust your thermostat accordingly to prevent the pipelines from freezing.
