So... we completely renovated our basement and the project seemed finished, but today we noticed mold growing on the back of a clock and warped pictures (mounted inside frames) on the same wall.
The wall is an exterior wall that is completely below grade. Because it is below grade, our contractor assured us that it did not need to be insulated, although the rest of the walls in the basement ARE insulated (since they are above grade, as the house lies on a slope).
Is the lack of insulation causing this problem, or could there be another culprit? What's the solution? HELP! Thankfully, we're within the warranty our renovation company provided, but I really don't want to perform costly repairs if (a) they're not needed, or (b) they're the wrong repairs.
