How to Weatherproof a House


How to Weatherproof a House. Making sure a house is weatherproofed and insulated can save on energy bills. Sealing gaps around windows and doors cuts down on drafts in cold months and keep air-conditioned air in the house during hot summer days. Using plastic sheeting to seal and insulate windows in the winter also lowers heating energy costs. Here are some steps you can take to weatherproof your house.

Things You'll Need

  • Candle
  • Tube of window caulk
  • Caulk gun
  • Utility knife
  • Bucket of warm soapy water
  • Clean rag
  • Double-sided tape
  • Scissors
  • Clear plastic sheeting
  • Hair dryer

Seal Window Gaps with Caulk

  • Identify gaps around windows. You need to seal and insulate all of the windows in your house. When feeling for drafts, you can use a candle. Just light it and hold it near each window. When the flame dances, a draft is likely the cause.

  • Insert caulk tube into the caulk gun.

  • Cut off tip of caulk tube with a utility knife.

  • Gently squeeze gun handle as you move along the perimeter of each window, laying down a solid seal of caulk as you go. This will insulate the living areas of your house.

Install Plastic Sheeting on Windows

  • Wash the inside edge of window panes with warm, soapy water.

  • Cut double-sided tape with scissors to fit along the inside of window pane.

  • Peel one side of the backing off of the tape and stick it to the window frame.

  • Peel off the exposed side of the double-sided tape on the top of the window.

  • Starting at one of the corners, stick the plastic sheeting to the tape, forming a complete seal. Leave about an inch overlap to be trimmed later. Move slowly across the window, sticking the plastic to the tape.

  • Repeat for the sides and bottom edges of the window.

  • Trim excess plastic with scissors or a utility knife.

  • Smooth out any wrinkles in the plastic by using a blow dryer. Keep the setting on low and slowly pass it over the plastic to shrink it to fit your window.

  • Repeat this process to seal every window in your house. This will ensure that you will get the most out of your new insulation.

Tips & Warnings

  • Many door "draft-stoppers" are available. They are designed to be placed along the base of your doors. These products are effective during winter months.
  • Most home inspections will tell you the status of the insulation in your home.
