Removing the Existing Casing
Before installing new exterior door casing, it’s essential to remove the existing casing carefully to avoid damaging the door frame or siding. Here’s a step-by-step guide to removing exterior door casing:
1. Gather necessary tools: Pry bar, hammer, utility knife, measuring tape, safety glasses
2. Inspect the casing: Examine the casing to determine the type of nails or screws used.
3. Remove nails or screws: Use the hammer and pry bar to remove the nails or unscrew the screws that are holding the casing in place. Be gentle to avoid denting the door frame or damaging the siding.
4. Pry the casing loose: Starting from one corner, insert the pry bar between the casing and the door frame. Gently pry the casing away from the frame, working your way around the perimeter.

7. Clean the door frame: Once the casing is removed, use a damp cloth to clean the door frame of any debris or paint residue.
Preparing the New Casing
Measuring and Cutting the Casing
Measure the height and width of the door frame and add 1/2 inch to each measurement to allow for overhang. Cut the casing to size using a miter saw or a hand saw and miter box. Make sure the cuts are clean and accurate for a professional-looking finish.
Priming the Casing
Apply a coat of primer to the casing to help protect it from moisture and ensure good paint adhesion. Use a paintbrush or a roller to apply the primer evenly. Allow the primer to dry completely before painting.
Painting the Casing
Choose a paint color that complements the exterior of your home and paint the casing using a paintbrush or a roller. Apply two coats of paint for durability and allow each coat to dry completely before applying the next.
Installing the Casing
Place the casing around the door frame, aligning it with the edges of the frame. Secure the casing in place using 2-inch finish nails or screws. Countersink the nails or screws slightly below the surface of the casing and fill the holes with wood filler for a smooth finish.
Measuring and Cutting the Casing
1. Measure the height of the door frame from the bottom of the sill to the top of the header. Add 1 inch to this measurement for the top casing and bottom casing.
2. Measure the width of the door frame from the outside edge of the jamb to the outside edge of the other jamb. Multiply this measurement by two for the left and right casing.
3. Cut the casing to the measured lengths using a miter saw. When cutting the casing, be sure to miter the ends at a 45-degree angle so that they will fit together snugly at the corners.
| Casing Piece | Length |
|---|---|
| Top Casing | Door Frame Height + 1 inch |
| Bottom Casing | Door Frame Height + 1 inch |
| Left Casing | Door Frame Width x 2 |
| Right Casing | Door Frame Width x 2 |
Installing the Head Casing
Measure the width of the door frame opening. Cut the head casing to this length, making a 45-degree angle cut on each end.
Apply a bead of caulk along the top edge of the door frame, where the head casing will sit.
Place the head casing in position, ensuring that the angled cuts fit together snugly and that the casing is level. Nail the casing into place through the pre-drilled holes, using 6d finish nails.
Finishing the Casing
- Countersink the nails slightly using a nail set.
- Fill the nail holes with wood filler and allow it to dry.
- Sand the wood filler smooth and paint or stain the casing to match the existing trim.
Installing the Side Casings
Next, install the side casings. Cut each casing to length, allowing for a 1/4-inch overhang at the top and bottom. Position the casing against the door frame and nail it in place with 6d finish nails. Countersink the nails slightly and fill the holes with wood filler.
Installing the Top Casing
Cut the top casing to length, allowing for a 1/4-inch overhang on each side. Position the casing against the door frame and nail it in place with 6d finish nails. Countersink the nails slightly and fill the holes with wood filler.
Mitering the Corners
To miter the corners, cut the casings at a 45-degree angle. Use a miter saw or a sharp handsaw. Dry-fit the casings to make sure they fit together properly. Apply a thin bead of wood glue to the mitered edges and press them together. Secure the casings with 6d finish nails.
Caulking the Joints
Once the casings are installed, caulk all of the joints between the casings and the door frame. Use a paintable caulk that matches the color of the casings.
Finishing the Casing
Prime and paint the casings to match the rest of the door. Use a high-quality exterior paint that will protect the casings from the elements.
| Tool | Use |
|---|---|
| Miter saw | Cut the casings at a 45-degree angle |
| Carpenter’s square | Ensure the casings are cut to the correct length |
| Hammer | Nail the casings in place |
| Caulk gun | Caulk the joints between the casings and the door frame |
Using Casing Nails for a Secure Fit
Casing nails are essential for securely attaching exterior door casing. These nails are specifically designed for this purpose, featuring a thin shank and a large head that holds the casing firmly in place. When driving casing nails, it’s important to use the correct technique to ensure a strong and durable installation.
Step 1: Choose the Right Nails
Select casing nails that are the right size for the thickness of your casing. The nails should be long enough to penetrate both the casing and the framing behind it, but not so long that they protrude through the other side.
Step 2: Position the Nails
Hold the casing in place and mark the locations of the nails along the top and sides. Space the nails evenly, typically 8-10 inches apart.
Step 3: Countersink the Nail Holes
Using a nail set, create small indentations at the nail locations. This will prevent the nails from splitting the casing.
Step 4: Drive the Nails
Hold the nail perpendicular to the casing and drive it in using a hammer. Sink the nail head just below the surface of the casing.
Step 5: Set the Nails
Use a nail set or nail punch to drive the nail head completely into the casing. This will conceal the heads and create a smooth finish.
Step 6: Using a Nail Gun for Efficient Installation
For larger projects or if you need to drive a large number of nails, using a nail gun can significantly speed up the process. Follow the manufacturer’s instructions for proper operation and safety precautions. Here’s a table comparing the steps for using a nail gun versus manual nailing:
| Manual Nailing | Nail Gun |
|---|---|
| Choose the right nails and mark nail locations | Load the nail gun with appropriate nails |
| Create countersink indentations | Align the nail gun and drive nails |
| Drive nails using a hammer | Press trigger to drive nails |
| Set nails using a nail set | Nails are set automatically |
Filling Nail Holes and Caulking
1. Once the new casing is in place, you’ll need to fill any nail holes with wood filler.
2. Apply the wood filler to the nail holes using a putty knife or your finger.
3. Smooth the wood filler over the nail holes and let it dry completely.
4. Sand the wood filler smooth once it’s dry.
5. Caulk the seams between the casing and the door frame.
6. Use a caulk gun to apply the caulk to the seams.
Caulk Types
| Type | Properties |
|---|---|
| Paintable | Can be painted to match the trim |
| Non-Paintable | Cannot be painted, so it must be matched to the trim color |
| Silicone | Waterproof and flexible, ideal for outdoor use |
| Acrylic | Less waterproof than silicone, but easier to apply and remove |
| Polyurethane | Paintable and waterproof, but more expensive than other types |
7. Smooth the caulk over the seams using your finger or a caulk tool.
Painting or Staining the Casing
Once the casing is installed, you can paint or stain it to match the rest of your home’s exterior. Here are some tips for painting or staining exterior door casing:
• Clean the casing thoroughly before you start painting or staining. This will help the paint or stain to adhere better to the surface.
• Use a primer before you paint or stain the casing. This will help to create a smooth, even finish.
• Use a high-quality paint or stain that is specifically designed for exterior use. This will help the finish to last longer.
• Apply the paint or stain in thin, even coats. Allow each coat to dry completely before applying the next coat.
• Protect the casing from the elements by applying a clear sealer. This will help to prevent the paint or stain from fading or peeling.
Additional tips for painting or staining exterior door casing:
- If you are painting the casing, be sure to use a paint that is compatible with the type of wood you are using.
- If you are staining the casing, be sure to use a stain that is compatible with the type of wood you are using. Stain penetrates and protects wood and shows of the natural wood grain, while paint is opaque and covers the wood grain.
- Use a brush or roller to apply the paint or stain. A brush will give you a smoother finish, but a roller is faster and easier to use.
- Allow the paint or stain to dry completely before opening or closing the door. This will help to prevent the finish from being damaged.
- Apply a second coat of paint or stain for a more durable finish.
- Inspect the casing regularly and touch up any scratches or peeling paint or stain as needed.
- Clean the casing with a mild detergent and water solution every few months to keep it looking its best.
- If you are not comfortable painting or staining the casing yourself, you can hire a professional to do it for you.
| Painting or Staining | Description |
|---|---|
| Painting | Opaque finish that covers the wood grain. |
| Staining | Allows the natural wood grain to show and seals and protects the wood. |
Tips for a Professional Finish
1. Use the Right Materials
Exterior door casings are typically made of wood, vinyl, or aluminum. Wood is the most traditional material, but it requires regular maintenance. Vinyl is low-maintenance and comes in a variety of colors and styles. Aluminum is strong and durable, but it can be more expensive than other materials.
2. Measure Accurately
It is important to measure the opening of your door carefully before ordering new casing. Measure the width of the opening, as well as the height from the threshold to the top of the door frame.
