To trim windows, measure and cut the trim pieces to fit around the window frame. Use nails or screws to attach the trim securely, then apply caulk around the edges to seal the gaps and protect the window from moisture. Choose a trim material that complements your interior or exterior design, such as wood, vinyl, or metal, and finish with paint or stain if desired.

Trimming windows involves cutting and fitting the trim pieces around the window frame and securing them with nails or screws. Sealing the edges with caulk prevents drafts and moisture. Paint or stain the trim to match the window design for a professional finish.
