Small cracks, ripped weather stripping and improperly sealed joints through out the home create ways for warm air to escape. This causes drafts or chills on cold days which will only get worse. Sealing up these cracks, insulating walls and closing outside vents will keep the warm air inside longer which means a lower heating bill and more comfortable winter.  You may have read How to Prepare Your Windows for the Colder Weather but there are other ways to weatherize your home.

Exterior

Carefully check the outside of your home for any visible holes or cracks.  Fill small holes with sealant and use a combination of fiberglass insulation and sealant on larger holes. Caulk around any electrical wiring, plumbing, or vents that enter your home as well as all windows and doors. If you have a storm door make sure that it seals well and replace weathing stripping if necessary as it acts as another barrier between the elements. Close vents and tightly cover conditioner units as these have the potential to suck the warm air directly outside. 

Inside Living Space

The interior of the home is usually the least of your concerns but can prove to be a huge source of cold air infiltration. Insulate behind outlets along exterior walls as there usually is no fiberglass insulation at these points. Seal the joint where the wall meets the floor behind the casing. This is usually a missed area because it is rarely thought of and it does require a little extra work. Also, if you have a fire place that you do not use then make sure to seal it with a rigid or inflatable plug.

In the Attic

Use a high temperature sealant around chimneys and furnace vents while using multipurpose sealant around any cracks or holes. If you can see any daylight coming through joints, vents or anything else make sure to seal these gaps. Stuff fiberglass insulation into an electrical or vent openings to reduce air exchange between the attic and upper floor. Be careful not to place this insulation onto recessed lighting fixtures unless they are rated for insulation contact. Check roof flashings for possible water infiltration into the attic as these may require resealing and if at anytime you notice the indications of water seepage check these areas immediately to stop continued damage.
