Wanting the house back to level isn’t the only reason to have reblocking done. While this might be the main reason from an aesthetic point of view, the fact of the matter is not having it done can be quite dangerous as a home that is tilting or sinking is no longer structurally sound. By leaving the home to continue in this manner could cause all kinds of associated problems to also arise. We understand that the cost of reblocking might be something that makes the idea one you may want to stay away from. But this would be a mistake. Replacing the stumps in the subfloor is not an especially expensive process if you have experts on hand. And furthermore, leaving the subfloor to sag or tilt can make it more expensive to fix in the long run since there’ll be other problems to fix too.
