(Please forgive me if I am not using proper carpentry terms)
I recently noticed I have a vertical wood frame popped out. I am suspecting it is caused by thermal expansion. I can see these are vertical frame joined by sectioned wood. I am living in Seattle so a bit worried about moisture intrusion to cause more damage.
I tried to use a hammer to put it into the slot but it barely moved at all.
My questions:
- Is it common for it to be popping out? Could it be caused by structural issues or just thermal expansion?
- How to fix it since hammer isn't quite helping? I don't think nail is a good idea because there is no nail at all on the trim.
Thanks in advance
