Old House Weatherization Tips

Keep the cold north winds out and warm heated air in for a more energy efficient home.

  1. Seal all cracks around window and door trim inside and out.
  2. Add weather stripping to all doors and windows. (Check for leaks by evaluating the smoke of an incense stick.) Make sure all windows have weather stripping on bottom of the sash, along the sides and at the meeting rail.
  3. Install foam insulation gaskets under electric cover plates on all outlets and switches.
  4. Seal up basement. Insulate bulkhead doors leading to basement. Seal all cracks in the foundation wall, both inside and out. Depending on location, this can be done with mortar or spray foam insulation.
  5. Add insulation to attic floor and floors above (unheated) crawlspaces and basements. (Vapor barrier should always face the heated space.)
  6. Make sure all attic door hatches are insulated and sealed.
  7. Add exterior storm windows to single glazed windows. Make sure they are properly sealed and caulked and have weep holes at the sill to allow moisture to escape. As a quick low-cost approach, add plastic sheeting to the interior of windows. Kits can be purchased at your local hardware store.
  8. Add wooden storm doors that are compatible with the home's architecture.
  9. Wrap all hot water pipes and air ducts. Turn off water to exterior faucets, drain, and cover taps with an insulated cover.
  10. Keep your fireplace flues shut tight when not in use. Fill the throat of the flue with insulation if the fireplace is not often used.
