Use a large utility knife to cut out the existing insulation from between the studs of the walls. Inspect the area for moisture or cracks in the foundation wall. You do not want water leaking into the insulation of your basement. Over time, this will allow unhealthy mold and mildew to build up.

Use polyurethane foam sealant to seal off any cracks, leaks, or gaps between the cement foundation and the home's wooden frame. Use caulk to seal off any openings where the home's electrical wires, vents, or pipes connect to the basement. For added protection, you can paint the walls with waterproof paint before installing the new insulation.

Measure the height and width of each wall so you know how much insulation you will need. Fiberglass insulation is sold in large rolls that can be cut to size once you bring it home. When purchasing insulation, look at the R-value. This measures the amount of heat the insulation can block.

Measure the distance between wall studs so you know what size to cut each panel of insulation. Roll out the insulation in your backyard or other open space. Breathing in the fiberglass can be harmful, so it is better to do this outside where you have plenty of ventilation. Cut the panels of fiberglass with a large utility knife or scissors.
