6 Exterior Window Trim Upgrades

Add a Splash of Color
Painting is a quick and easy project if you’re new to DIY. Paint your trim a bright color or something like a dark black to contrast with your home’s exterior walls. Another fun idea: Use multiple colors. Paint the parts of the trim that go over the windows one color, and the trim along the perimeter of the window another.

Add Window Boxes
Another way to add color to your home’s exterior: Build window boxes and fill them with flowers. Window boxes add dimension to your home and can really give nice curb appeal. They’re also relatively simple to put together without too many tools. Finish them with stain or a coat of paint.
It save time, you can also buy planter boxes online. This option on Amazon comes with an easy installation kit. Order it in black, espresso or white.
