I am going around caulking behind the insulation due to drafts. Part of basement sits above ground, as house is built on slope. Many of the nuts on these foundation anchors are loose. I have been tightening them with a socket wrench until firmly but not over doing it.
First are these supposed to be loose? The house is 2yrs old. Did they forget to tighten these or did they come loose as the house settles. Some were sitting halfway up the stem.
How tight should they be?
