Complete Interior Trim
One Coordinated Finish From Room to Room
Interior trim looks best when the individual components relate to one another. Baseboard height should complement casing width. Crown moulding should suit the ceiling height, while wall details need to align naturally with doors, windows and other architectural features.
For larger renovations and custom-home projects, Miter5 can coordinate the full trim package so these details remain consistent throughout the interior.
Interior Doors
Door Installation as Part of the Finished Interior
A finished doorway is more than the door slab itself. The jamb, hardware, casing and surrounding baseboards all need to align correctly for the opening to look right and operate properly.
Miter5 installs standard swing doors, French doors, pocket doors, barn doors, solid-core doors and specialty interior door systems.

Balanced Proportions
Baseboards, casing, crown and wall details are installed in proportions that complement the room and surrounding finishes.
