Trim refers to the decorative woodwork installed around doors, windows, ceilings, and floors. Casing specifically frames the perimeter of a door or window opening, covering the gap between jamb and drywall.
In practice
You'd see this when a homeowner in Salmon Creek, WA is finishing a basement remodel and CRM Services installs door casings and baseboards.
Why it matters
Trim and casing work appears at the end of nearly every interior remodeling project.
Common questions
Can I just match existing trim or do I need to replace it all?+
Matching is often possible if the profile is a standard style. The challenge is matching paint color after years of fading.
Why does my casing pull away from the wall?+
Usually from drywall movement, improper nailing, or moisture warping — MDF is especially vulnerable in wet areas.
