I am replacing an old vinyl window. The previous window had a separate storm window on the outside (which I removed). Now there is wood exposed to the elements. I live in Minnesota where it's hot and wet in the summer and very cold in the winter. I am concerned about having this wood exposed.
I plan on
- Scraping, sanding and repainting the wood with oil-based, exterior paint
- Installing the sill edge (below the window)
- Insulating and caulking
But I am wondering if I need to do anything else? Do I need to install some type of flashing?
Any help is appreciated.
