Door Casing & Trim Installation in Charleston, SC

Plinth blocks are decorative blocks at the base of door casings where the casing meets the baseboard. They create an elegant transition and eliminate the need for a difficult miter or cope joint. Rosettes are decorative corner blocks at the top corners of door casings that add traditional character. Both are popular in Charleston's historic and traditional homes.

Absolutely. We install new door casings around your existing doors without disturbing the door itself. We carefully remove old trim, prepare the surface, and install new casings with proper reveals and tight joints. This is one of the most cost-effective upgrades for Charleston homes looking to elevate their interior trim.

Charleston homes vary widely in style. For historic downtown Charleston homes, we often use period-appropriate profiles with backband details and rosettes. For Lowcountry traditional homes, craftsman-style casings with built-up headers work beautifully. For newer construction in Mount Pleasant or Summerville, clean colonial profiles or modern flat-stock casings are popular choices.

Door casing installation typically ranges from $150-350 per door opening depending on the profile style and complexity. Adding headers increases the cost by $75-150 per door, and plinth blocks add $30-50 per pair. A whole-home door casing upgrade for 15-20 doors usually ranges from $2,500-6,000. We provide free estimates that include material and labor.

For a cohesive look, we strongly recommend using the same casing profile on all interior doors throughout your home. Consistency in door trim is one of the hallmarks of quality finish carpentry. However, you can add extra detail in focal areas — for example, built-up headers with crossheads on main living area doorways while keeping bedroom doors with simpler casings.

Door casing and door trim are often used interchangeably. Technically, 'casing' refers specifically to the trim pieces that frame the door opening (head casing and side casings), while 'door trim' is a broader term that can include the casing plus any additional elements like headers, plinth blocks, rosettes, or backband. We install all door trim components.

Yes, craftsman-style door headers (also called crossheads) are one of our most popular upgrades. They add substantial architectural presence above doorways and create a more finished, custom look. We can install simple flat-stock headers, built-up designs with backband and crown details, or full pediment-style headers depending on your desired style and ceiling height.
