Caulking, caulking and caulking.

But what exactly needs to be caulked?

Caulking should be done where two different materials meet such as
where brick meets windows or siding, around door frames and vents.
Also in the attic where wires go through wood framing. (Many
localities require fireproofing caulk in these holes) If you have hot
water heat you can insulate the openings for pipes or ductwork if you
have forced air. The foam backer pad that can be put behind your wall
switch plates can have a noticeable effect.
