How to Replace Door Frame Molding: A Comprehensive Guide316

Introduction

Door frame molding serves both functional and aesthetic purposes, providing a finished look to your doorways and protecting the edges of your drywall from damage. Over time, molding can become damaged due to wear and tear, moisture, or impact. If you find yourself needing to replace your door frame molding, follow this comprehensive guide to do it like a pro.

Materials and Tools
New door frame molding (select the size and style that matches your existing molding)
Measuring tape
Pencil
Miter saw or miter box
Construction adhesive
18-gauge brad nailer
Caulk gun
Caulk

Step 1: Measure and Cut the Molding

Measure the length of the existing molding on one side of the door frame. Transfer this measurement to the new molding and mark it with a pencil. Use a miter saw or miter box to cut a 45-degree angle at the end of the molding. Ensure that the angle aligns with the direction of the molding on the door frame.

Step 2: Apply Adhesive and Position the Molding

Apply a thin bead of construction adhesive to the back of the cut molding. Position the molding on the door frame, aligning the cut edge with the corresponding cut on the existing molding. Apply pressure to ensure secure adhesion.

Step 3: Secure the Molding

Use an 18-gauge brad nailer to drive nails through the molding into the door frame. Space the nails approximately every 6 inches. Countersink the nails slightly below the surface of the molding using a nail set.

Step 4: Apply Caulk

Apply a bead of caulk along the seam where the new molding meets the existing molding and along the edges of the molding where it meets the drywall or door frame. Use a damp rag to smooth out the caulk and remove any excess.

Step 5: Repeat for Other Sides

Repeat steps 1-4 for the remaining sides of the door frame. Ensure that the mitered angles align perfectly and that the molding is securely attached.

Step 6: Touch-Up and Clean

Once the caulk is dry, use a utility knife to trim any excess caulk. You can also touch up any nail holes or imperfections with wood filler and paint if necessary. Clean up any debris from the work area and leave your door frame with a fresh and finished look.

Tips
Choose molding that matches the style and species of your existing molding for a cohesive look.
If you are inexperienced with using a miter saw, practice on scrap wood before cutting your actual molding.
Use a brad nailer specifically designed for finish work to minimize damage to the molding.
Allow the caulk to dry completely before painting or staining the molding.

Replacing door frame molding is a relatively straightforward task that can enhance the appearance and functionality of your doorways. By following these steps carefully and using the right materials and tools, you can achieve professional-looking results.
