We'll cover what's included, benefits, installation, and pro tips for choosing the right kit.
What is a Pre-Mitered Door Trim Kit?
A pre-mitered door trim kit contains all the interior trim pieces needed to finish a door opening. The casing, stop molding, and sill trim come pre-cut with precision 45-degree mitered ends. This allows the trim to fit together perfectly around the door frame.
Types of Door Trim Pieces
Here are the main trim components included in a kit:
- Casing - The outer frame that encloses the door opening. Casing overlaps the door jamb and walls.
- Stop - The interior trim at the door jamb opening. Paired with casing for a finished look.
- Sill - Bottom trim piece on the threshold below the door.
Why Choose a Pre-Mitered Kit?
Pre-mitered kits eliminate the need to measure and cut trim pieces individually. The pre-cut miters ensure proper alignment so pieces join seamlessly. This prevents gaps and mismatched corners. Pre-mitered kits create clean sight lines for a flawless, built-in look. Installation is faster with no miter cuts required on-site.
Benefits of Using Pre-Mitered Trim Kits
Easier Installation
Installing door trim with a pre-mitered kit is straightforward even for beginners. Simply trim jamb extensions as needed, test fit the pieces, then adhere with adhesive and nail in place. Detailed instructions walk you through each step. Without any miter cutting, installation is faster than installing individual molding boards.
Precise Fit
Pre-cut mitered joints ensure trim fits tightly. The casing corners seamlessly align at 45-degree angles. Gaps are minimized for smooth transitions between boards. Your trim will have crisp lines and tight seams where pieces join.
Professional Finish
Pre-mitered kits produce expert results. The precision mitered cuts lend a built-in, high-end look. With uniform boards and angles, the finished trim has consistent gaps and sight lines. No more guessing miter angles and hoping boards line up evenly.

Step-by-Step Installation Guide
Follow these steps to install pre-mitered door trim:
- Remove existing interior door trim and jamb if present.
- Cut jamb extensions to width if your door frame depth changed.
- Do a dry test fit without nailing to ensure pieces align properly.
- Affix trim using wood glue and nail or screw in place. Avoid nailing through the visible face.
- Fill any gaps with wood putty. Let dry completely.
- Sand trim smooth in preparation for finishing.
- Apply primer then paint or stain to match existing trim.
Finishing Pre-Mitered Trim
Pre-mitered kits come as raw wood ready for finishing. Carefully sand and fill any imperfections prior to painting or staining. On paint grade trim, use primer first for best adhesion. For stain grade, apply your choice of oil or water-based stain. Always test products first before applying to the installed trim. Finish all sides of the trim, not just the front face. This ensures consistent moisture protection and appearance.
Pre-Mitered Trim Maintenance
Like all wood trim, pre-mitered kits need minor upkeep over time. Occasionally inspect for any gaps that may open up seasonally with temperature and humidity changes. Fill these with putty as needed. Use touch up paint or stain pens to conceal any nicks or dings. When trim starts looking worn or discolored, consider refinishing for a fresh look.
Pre-mitered door trim kits make installing interior trim easy, even for beginner DIYers. With pre-cut pieces, you skip the challenging miter cuts and measuring. Simply secure the interlocking boards for a seamless fit. Pre-mitered kits also deliver professional quality results. Uniform trim angles and tight joints result in clean lines, consistent gaps, and a cohesive look. For dramatically upgrading doorways with ease, a pre-mitered kit is the way to go.
