My Basement Floor Is Freezing

If there are gaps in the concrete floor such as cracks or where the basement floor meets the foundation wall the cove joint or seam between the foundation and the floor slab ground water is forced up through them and into your basement.

My basement floor is freezing.

I know my most likely option is space heaters. Inside the wood sidewalls of the house it s colder than that. The greatest offender though is ground level cold. When the humidity level rises above 80 mold and mildew start to grow.

In fact the problem could well be your floor especially in a room at ground level or worse yet in the basement. Floors of ceramic stone or concrete are the worst culprits with hardwood a runner up. I have a 32 year old split entry 1550 sq ft. Another bedroom upstairs is even warmer.

When the ac or heat is set to 71 the basement temp is 52 and my bedroom on the 3rd floor is 75. The cold air just pours into the basement from the uninsulated balloon frame. Ground level cold is the real culprit. There are 2 bedrooms and a den down there.

The floor is probably the biggest source of heat at 38 f. Wondering what the best space heaters would be. Other causes of a high water table and seepage into the basement. My basement windows are above ground.

My basement was refinished last year. Keep cold air out warm air in. The basement is completely finished but it is super cold compared to main floor. The reason for this is because basements tend to be a damp and cold environment due to moisture coming up through the foundation water sources or from high humidity inside of your home.

It cascades into your basement through windows ducts vents pipes spaces around intrusions around the rim joist header joist and from non conditioned rooms overhead. Virtually all the coldness in a basement originates in air drafts and heat loss taking place up high at or above ground level. Walls that extend above grade vents ducts windows and more act as freeways that allow cold to cascade into your basement. One poorly insulated dryer vent and duct will chill your basement far more than an entire below grade basement wall.

Also the heat rises upstairs and heats the house. It really helps make the room comfortable. Approximately 600 sq feet. Moisture makes it feel colder.

Including a new central air system. It is recommended that you have a dehumidifier going in your basement at all times. I had insulation blown in the attic in 2011. Just moved into my first house with a basement.

The basement walls were insulated between the foundation and drywall. Last year i removed my wood burning stove in the basement family room and had an gas fireplace insert installed.
