Door Frame Molding: What's It Called?

Ever found yourself wondering about the name of that rectangular or square-shaped piece of material that surrounds your door, fitting snugly into the gap between the door and the wall? You're not alone. In the world of home improvement and architecture, this component is known as a door stop, door jamb, or more commonly, a door frame. But what about the molding that adorns this frame, adding a touch of elegance and completing the look? What is it called?

In the realm of carpentry and interior design, the molding around a door frame is typically referred to as door casing or door trim. This decorative element serves both functional and aesthetic purposes, enhancing the overall appearance of your door and room. Let's delve into the details of door casing, its types, purposes, and installation.

Understanding Door Casing

Door casing, or door trim, is a type of molding used to cover the gap between the door frame and the wall. It's usually made from wood, but you can also find it in materials like PVC, composite, or even metal. The primary function of door casing is to conceal the rough edges of the door frame, providing a smooth, finished look.

In addition to its aesthetic role, door casing also plays a part in protecting the door frame and wall from damage. It helps prevent the door from rubbing against the wall, which could otherwise cause scuffs, scratches, or even damage to the drywall. Moreover, it provides a surface for the doorstop, preventing the door from slamming into the wall and causing potential harm to both the door and the wall.

Types of Door Casing

Door casing comes in a variety of styles, sizes, and materials to suit different tastes and needs. Here are some of the most common types:

• Stock Door Casing: Available in standard sizes at home improvement stores, stock door casing is a cost-effective option for basic door trim needs.
• Custom Door Casing: Made to order, custom door casing offers a tailored fit and a wide range of design options, including intricate profiles and materials like solid wood or metal.
• Pre-finished Door Casing: Pre-finished door casing comes with a factory-applied finish, saving you time and effort in painting or staining.
• Primed Door Casing: Primed door casing has a base coat of primer applied, making it easier to paint and providing better adhesion for the final coat.

Door Casing Profiles

Door casing is available in a wide range of profiles, or shapes, that can significantly impact the overall look of your door and room. Some common door casing profiles include:

• Ovolo: An S-shaped profile that's simple and elegant, ovolo door casing is a popular choice for traditional and transitional styles.
• Egg and Dart: Named for its distinctive design featuring egg-shaped indentations and pointed darts, egg and dart door casing adds a touch of classical charm.
• Beadboard: Characterized by its vertical grooves, beadboard door casing offers a rustic, cottage-like appeal.
• Flat Stock: Simple and clean, flat stock door casing is a versatile option that works well with contemporary and modern styles.

When selecting door casing, consider the overall design and style of your room, as well as the size and shape of your door frame. The right door casing can enhance the appearance of your door and complement the architecture of your space.

Installing Door Casing

Installing door casing is a relatively straightforward DIY project that can be tackled with basic tools and a bit of patience. Here's an overview of the process:

1. **Measure the Door Frame:** Begin by measuring the width and height of your door frame to determine the size of the door casing you'll need.

2. **Cut the Door Casing:** Using a miter saw or miter box, cut the door casing pieces at 45-degree angles to create mitered joints at the corners. Ensure that the inside edges of the casing are flush with the inside edges of the door frame.

3. **Apply Adhesive:** Apply a construction adhesive, such as wood glue, to the back of the door casing pieces. This will help secure the casing to the door frame and wall.

4. **Install the Door Casing:** Starting with the top piece, position the door casing onto the door frame and wall, ensuring that the mitered joint is at the corner. Use a finish nailer or hammer and nails to secure the casing in place. Repeat this process for the remaining pieces, ensuring that the mitered joints are tight and the casing is flush with the door frame and wall.

5. **Fill and Sand:** Use wood filler to fill any nail holes or gaps in the door casing. Allow the filler to dry, then sand the surface smooth.

6. **Paint or Stain:** Apply a paint or stain to the door casing, following the manufacturer's instructions. Allow the finish to dry completely before using the door.

Tips for Installing Door Casing

• Always wear safety glasses when cutting and installing door casing to protect your eyes from debris and nails.
• Use a level to ensure that the door casing is installed straight and plumb.
• Test-fit your door casing pieces before applying adhesive or nails to ensure a proper fit.
• If you're unsure about any aspect of the installation process, consult a professional or seek advice from a home improvement store associate.

By installing door casing, you'll not only enhance the appearance of your door and room but also add a touch of personal style and craftsmanship. With a wide range of materials, profiles, and finishes available, you're sure to find the perfect door casing to suit your needs and tastes.
