How to Insulate the Ceiling in a Damp Basement


If your basement is cold and damp, consider insulating it. Begin by insulating your basement walls first; this will provide you more warmth for the time and money you’ll spend. If you want additional warmth on the first floor of your home, insulate your basement ceiling as well. Before you insulate the ceiling, check for dampness and resolve any leaks or water seepage problems.

Things You'll Need

  • Flashlight
  • Gloves
  • Fiberglass insulation
  • Stepladder
  • Staple gun and staples
  • Duct tape
  • Utility knife

Check for Dampness and Make Repairs as Necessary

  • Inspect your basement for leaks. Take a flashlight and look in and around areas that appear damp. Inspect all pipes coming into and going out of your house for signs of leakage.

  • Inspect the foundation of your house for cracks that may have formed. Consider sloping the ground around your house away from the foundation, and run drain pipes from the downspouts to areas away from your house.

  • Repair any leaky pipes or water coming into your house through the foundation. Hire a plumber or contractor to make these repairs if you don’t feel confident doing so yourself.

Insulate Your Ceiling

  • Install the pieces of fiberglass batting in your basement ceiling, behind and around the wiring, pipes, and ceiling joists. Cut each section of batting with a utility knife to the size you need for the space you're insulating.

  • Staple the paper-faced side of the insulation to the bottom edge of the ceiling joists.

  • Insulate the wood framing around the perimeter of the ceiling that is above the foundation wall. Staple the insulation as you did to the ceiling joists.

  • Insulate around the ductwork and hot-water pipes that hang below the ceiling by taping the fiberglass batting on with duct tape.
