  • Excess moisture

What Makes It Cold In The Basement?

Being at the lowest level of the house, a basement's temperatures would be around 40 degrees Fahrenheit even during the winter. If you have an unfinished basement, it will feel cold because of the bare concrete. For finished basements, it can feel too chilly even with insulation.

Why Are Basements So Cold In Summer?

The summer has come, but unpredictable as the weather, your basement still feels cold. The main reason is the density of cold air. The warmer air molecules rise to other floor levels, while the colder air goes to the lowest part of the house. That is why even though the temperature is hot outside, the cold is consistent in the basement.

Another issue involves high humidity levels during summer. With the warm air, more moisture remains. If this humidity mixes with the cold temperatures, the basement will be cold. Other than the cold, excess moisture will also cause molds and musty odors that may pose health risks to family members.

The cold temperature could also be due to below-grade walls and floors. You have to install proper insulation systems to solve the issue. But then, if you have poor insulation installed, it can cause more cold air inside. For structural insulation issues, ask your contractor for help.

How Do You Keep A Cold Basement Warm?

It is best to maintain the ideal temperature for your basement with proven ways to battle the cold in your basement. You can prevent the cold from lingering in your basement with these practical solutions below that will keep your cold basement warm:

  • Keep your basement doors and windows closed so that warm air circulates inside.
  • Place carpets or rugs to keep the heat in the basement.
