    Can you caulk in the gap between counter and wall? It would most likely significantly reduce air leak. If you can get to rear wall inside lower cabinets, check there to insure no cracks are admitting air. If your kitchen is over your basement, see if other air leaks exist. Wrap your kitchen water pipes with foam pipe wrap, that is pre-slit and sized to fit your pipes. Fill any holes around water pipes with minimally expanding foam.

  • Run a line of caulk in the gap to seal it.

    Get a can of the low-expansion foam gap filler (used around doors and windows). Spray in a small amount of foam to seal the gaps about half way. Don't put in too much, because it continues to expand and you will have to trim it off about a day later.

    I would first look inside the cabinet under the sink and see if you can locate the crack or gap happening there. If just a crack, go with the caulk suggestions already posted. If there is a gap, pick up some weather stripping and see if that fills the area first then caulk over it.

    They also sell gap filters, if the hole is too big to caulk. Or you can put a piece of molding in that area to block the cold.

    First check out why there is cold air coming in, has something been compromised with a crack or a hole, Then hopefully you can get the repair done if needed. If nothing is wrong, caulk where it is coming in.
