Install a subfloor above the concrete. This will help to keep the floor warm if you’re installing flooring on top. It will also help to keep moisture away from the floor.
Insulate the basement walls, floors and crawlspace (if you have one) to trap in the heat, making the floors warmer.
Install radiant heating. This type of heating system delivers heat right to the floor. Radiant heating elements are installed under the floor, which keeps the floor and the room warm. This heating system also uses less energy than conventional heating systems.
Lay rugs or mats in various spots around the basement. This is a low-cost and effective method of making the floors feel warm.
Install carpet on the basement floor. Even the most inexpensive carpet helps make the concrete floors feel warm.
