How to Winterize Windows & Doors

Gaps in doors and windows can cause major energy loss from the home.

Your home can lose heat during the winter due to gaps in windows and doors. According to the U.S. Department of Energy, drafts are responsible for the loss of between 5 and 30 percent of your home energy. Windows that are not sealed properly and doors with large gaps at the foot will cause major energy loss. Spending a little money on energy-saving seals will reduce your heating bills during the winter and, in the long run, save you money.

Things You'll Need

• Socks
• Kitty litter
• Neoprene
• Scissors
• Window insulation kit
• Soap
• Caulk gun
• Caulk tube
• Nail

Instructions

Cheap Energy Savers

1. Fill several old socks with kitty litter and place it at the foot of the door and on the window sill to reduce drafts from the two areas.

2. Cut a length of neoprene stripping that is long enough for the bottom of the window and remove the adhesive back. Run your finger along the neoprene, from one end to the next, to adhere it to the window. Do the same for the top and bottom of your home door to reduce drafts.

3. Clean the window thoroughly using soap and water. Cut the shrink film from a window insulation kit to the size of your window using a pair of scissors. Peel off the back of the film insulation and apply the film with the sticky side facing the window. Apply the film slowly, going from one end of the window to the other, working out any air bubbles along the way. Follow the instructions on the side of the package, since some window films require heat from a hair dryer, or application with water.

Caulking Windows

1. Insert a tube of caulk into a caulk gun and cut off the tip with a scissor. Make the cut so that the end has a 1/4 inch gap. Poke a nail into the hole and press the trigger of the caulk gun to ready it.

2. Run the tip of the caulk gun along any cracks in the window, such as in corners or where two different building materials meet. Apply caulk in those areas.

3. Wipe away any excess caulk from the window using a wet finger or wet rag.
