Trimming exterior windows involves measuring and cutting the trim pieces to fit around the window frame. Secure the trim with nails or screws, and seal the edges with caulk to prevent moisture damage. Choose a trim material that complements your home’s exterior design, such as vinyl, wood, or aluminum, and ensure proper sealing for weatherproofing.
