I have replaced some windows and bad trims. The new windows have different sizes so now I ran into few challenges.
If I put small pieces of siding to patch that area in red circle, (1) how do I "seal" in between the siding, and best with nice cosmetic fix? Another option is to replace the entire right side of the new window (but then I need to buy more sidings).
There were lots of places like below photos where the siding does not meet the trim completely. Some are 1/4" wide. (2) Do I just caulk it? What type of caulk is best for such gap?
The original trims oddly placed on top of siding as below. I need to cut back the sidings a bit and put new trims. (3) But do I need to wrap the corner with waterproof wrap or something? There are some water damage visible inside.
