When it comes to home design, door casing often gets overlooked, yet it plays a crucial role in your interior's overall aesthetic. This trim not only frames your doors but also adds character and elegance to your space. Whether you're renovating or building from scratch, understanding the importance of door casing can elevate your home’s style.
You might be surprised to learn that door casing comes in various styles and materials, each with its own price range. From simple MDF options to more ornate wood designs, costs can vary significantly, typically ranging from $1 to $10 per linear foot. Investing in the right door casing can enhance your home’s value while providing a polished finish that ties your rooms together beautifully.
Overview of Door Casing
Door casing, also known as doorway casing, is the trim or moulding that surrounds the door frame. Its primary purpose is to conceal the gaps between the door frame and the wall, which enhances both the aesthetic and structural integrity of the doorway. This trim helps finish the room's appearance, making it look more refined and polished.
Components
Doorway casing typically consists of three main pieces:
- Two long vertical pieces installed on either side of the door.
- A horizontal head casing that goes along the top of the door.
These pieces are generally made of wood or synthetic materials. They're milled to be slightly thinner on the edge that fits toward the inside of the door frame, reducing bulk and ensuring a sleek finish.
Types of Door Casing
- Mitered Trim: This style connects the pieces above the door with 45-degree angled (mitered) joints.
Types of Door Casing

Door casing comes in various designs, each offering unique aesthetics and functionality. Understanding these types allows you to choose the right style for your space.
Traditional Styles
- Colonial Casings: Characterized by raised edges and mitered corners, Colonial-style casings often incorporate subtle elements like beads and cavettos. This classic style enhances elegance and suits a wide range of home designs.
- Victorian Casings: Known for their elaborate details and decorative moldings, Victorian casings create a sense of grandeur. These casings may feature intricate patterns and curves, adding a touch of sophistication to any setting.
- Craftsman Casings: Emphasizing simplicity and craftsmanship, Craftsman casings showcase clean lines and sturdy construction. These casings typically feature wider profiles and flat surfaces, making them ideal for bungalows and Arts and Crafts homes.
- Mitered Casings: Mitered casings connect the side pieces and header using 45-degree angled joints, creating a seamless right angle. This style fits well in modern or minimalist designs, providing a sleek and streamlined appearance.
- Butted Casings: Butted casings place the header directly on top of the side pieces without angled joints. This style offers a more traditional look while drawing the eye upward, making it suitable for rooms with high ceilings.
- Square Edged Casings: Featuring square edges without ornate details, square edged casings lend a contemporary feel. Their simplicity allows them to complement various interior styles, from modern to transitional.
Materials Used in Door Casing

Door casing materials significantly impact both aesthetics and functionality. Various options are available, with wood being one of the most popular choices among homeowners.
Wood
Wood serves as a traditional material for door casings due to its durability, natural appearance, and versatility.
- Types of Wood: Common species used include oak, maple, poplar, mahogany, cherry, birch, and walnut. Oak and maple are particularly valued for their strength and excellent stain acceptance. Each species has distinct characteristics, influencing your choice based on style and function.
- Cost: The price of wood door casings varies. Basic hardwood options start at approximately $1 per linear foot, while ornate designs or exotic woods can exceed $10 per linear foot.
- Maintenance: Wood casings require regular maintenance, especially in exterior applications. Treating them with sealants prevents rot and preserves their appearance and longevity.
- Styles: Wood casings can be stained or painted, providing a wide range of finishes. This flexibility allows you to match your door casing with your home's decor.
Composite Materials
Composite materials offer a modern alternative to traditional wood door casings, combining durability with cost-effectiveness.
- Types of Composites: Common composite materials include MDF (medium-density fiberboard) and PVC (polyvinyl chloride). These materials replicate the look of wood while providing enhanced resistance to moisture and pests.
- Cost: Composite door casings typically start at around $0.50 per linear foot, making them a budget-friendly option compared to solid wood.
- Maintenance: Composite materials require minimal maintenance. They resist warping, cracking, and fading, making them suitable for various environments, including high humidity areas.
- Styles: Composite casings can be finished with paint to suit your aesthetic. They offer a contemporary look, blending seamlessly with modern home designs.
By understanding these materials, you can make an informed decision that enhances your home's appeal and longevity.
Benefits of Proper Door Casing

Proper door casing offers several benefits that enhance the functionality and beauty of your space. Two key advantages include aesthetic appeal and increased durability.
Aesthetic Appeal
Door casings serve as decorative trim around the door frame, providing a polished look for your entrances.
- Decorative Trim: Door casings act as essential decorative trim, enhancing the visual interest of your doorways and framing your doors attractively[1][2][5].
- Style Variations: You can choose from a wide range of styles, including Colonial, Georgian, modern, minimalist, craftsman, and rustic, allowing you to select a design that complements your home’s architecture[2][4][5].
- Visual Continuity: By matching door casings with your home’s overall aesthetic, you achieve visual continuity, creating a seamless look throughout the space[3][4].
- Enhancing Doorways: Door casings can transform ordinary doorways into eye-catching focal points, adding sophistication and architectural elegance to your interior design[3].
Durability and Protection
Proper door casing not only enhances aesthetics but also contributes to the longevity and protection of your doorways.
- Protection from Damage: Casings protect doors and walls by concealing gaps and preventing moisture and debris from entering.
- Material Choice: Selecting durable materials like hardwood or composite options ensures your door casings withstand wear and tear over time, maintaining their appearance and functionality.
- Maintenance Requirements: Proper maintenance applies to your door casings, with materials like PVC and MDF requiring minimal upkeep compared to traditional wood options.
- Investment Longevity: Investing in quality door casings contributes to your home's overall value, ensuring your doorways remain visually appealing and structurally sound for years to come.
Tips for Installation

- Measuring and Marking the Reveal: Use a combination square to establish a consistent reveal, maintaining a gap of 1/8 to 1/4 inch around the entire door frame. This approach ensures a balanced and symmetrical look.
- Preparing the Area: Ensure the jamb and wall are flush prior to installation. For projecting jambs, plane them flush with the wall. For recessed jambs, utilize shims behind the casing to level it with the wall surface. If the wall extends beyond the jamb, consider rabbeting the back of the casing or adding jamb extensions.
- Cutting the Trim: Start with cutting the top piece of trim. This step helps secure tight corners and proper fitting. Cut each end of the top casing at a 45-degree angle using a miter box. Use the initial piece as a template for subsequent pieces for consistency.
- Test Fitting: Conduct a dry fit of the trim pieces around the door to verify alignment and fit. Adjust as needed to achieve the best results.
