How to Pick the Right Interior Trim for Your Windows

Also known as molding pieces, interior trim boards are widely used to cover joints between different materials and surfaces. You’ll recognize them mostly as base molding at the bottom of a wall or as casings around your doors and windows. But with many different designs available, it can be hard to pick what’s best for your home’s interiors. To help you make an informed decision, window replacement specialist Renewal by Andersen® of Montana shares what you need to know:

Right Interior Trim for Your Windows

Different Types of Trim

Trim can be applied in almost any interior decorative element such as crown molding, columns, ceiling medallions, baseboards and even fireplace surrounds. Door and window casings also count as interior trim, as they create a frame around the opening while also hiding the gap between the adjacent wall and the jamb.

Tips to Keep in Mind

  • Trim Elements Must Match – Within each trim style, you’ll often have additional design options. Your selections must be suited with each other especially where the trim places intersect. For instance, the vertical pieces on a paneled wall shouldn’t be thicker than the horizontal trim. However, there are some exceptions, such as a plate rail meeting the casing of your picture windows. The end of the plate rail must be finished with a return so the end grain is covered.

  • Be Consistent – While you may choose more than one trim style for each of your windows and doors, you need to be sure that they all conform to your overall interior design. Don’t go all out on choosing many trim styles throughout your home’s interiors, as they can stand out more than the rest of the design elements and lose their visual appeal.

The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
