We’ve been in our home for a couple of years. We’ve had various issues (this seems to be a common theme for new home owners regardless of the age of the house). The home was built in the 1920s so almost everything is wooden.
This year we’ve noticed a change in the wood floor in many areas of the home. Specifically, more boards creak and some even seem to give more than they used to. Part of this may be caused by the shifting of several sets of jacks used to provide additional support to the floor joists. Until I go back under the house I won’t know if the jacks have shifted – this is very possible if they weren’t set on a solid base such as concrete or blocks.
Regardless, I believe I’ve narrowed down one other cause. The amusing aspect of this is that it turned out to be the opposite of what I expected.
