Installing the Trim
Once the door is hung, it’s time to install the trim to finish the look and provide support. Here’s a step-by-step guide:
1. Measure and Cut the Trim: Measure the width and height of the jambs and header around the door. Mark the lengths on the trim and cut it using a miter saw or a miter box and a handsaw.
2. Dry Fit the Trim: Place the trim pieces dry around the door opening to ensure proper fit. Adjust the cuts or shims as needed for a snug fit without gaps.
3. Secure the Jamb Trim: Start by attaching the jamb trim to the vertical sides of the jambs. Use wood glue or finishing nails to secure it. Ensure that the corners are mitered neatly.
4. Install the Casing Trim: Casing trim covers the jamb trim and provides a decorative frame around the door opening. Here’s where extra detail comes in:
- Measure the Depth of the Casing: Measure the distance from the face of the jamb to the edge of the finished wall surface. This will determine the depth of casing needed.
- Cut the Casing to Length: Cut the casing pieces to the lengths measured in Step 1, mitering the corners to fit around the door opening.
- Attach the Casing: Secure the casing to the jamb trim using wood glue and finishing nails. Make sure to seal any gaps between the casing and the jamb trim.
- Install the Header Trim: Finally, attach the header trim to the top of the door opening, mitering the corners to fit. Use wood glue and finishing nails for securement.
- Fill Gaps and Touch Up: Once the trim is installed, fill any remaining gaps with wood filler or caulk. Lightly sand and paint or stain the trim to match the surrounding walls and décor.
Adjusting the Door
Once the door frame is securely installed, you’ll need to adjust the door to ensure it hangs straight and operates smoothly. Here are five key steps:
1. Level the Door
Use a level to check if the door is level both horizontally and vertically. Adjust the hinges by tightening or loosening the screws as needed until the door is perfectly level.
2. Set the Strike Plate
The strike plate is the metal plate on the door frame where the latch of the door lock engages. Hold the door closed and mark the location of the latch on the door frame. Chisel out a small notch to accommodate the strike plate and screw it firmly in place.
3. Adjust the Latch
Use a screwdriver to adjust the latch on the door so that it aligns correctly with the strike plate. The latch should extend just enough to engage with the strike plate without catching or binding.
4. Set the Gap
There should be a small gap between the door and the frame to allow for movement. Use wooden shims to fill any gaps that appear when the door is closed. Remove the shims and tighten the screws on the hinges to secure the door in place.
5. Fine-Tune the Operation
Once the door is installed, carefully check how it operates. If the door binds or rubs against the frame, adjust the hinges, strike plate, or latch as needed to achieve smooth operation. Lubricate the hinges regularly to prevent squeaking.
Securing the Door
Now that the hinge side of the door is secure, you can focus on the strike plate side. The strike plate is the metal plate that the door latch hooks onto when the door is closed. To install the strike plate:
1. Position the strike plate: Hold the strike plate over the door jamb where the latch will catch, ensuring that it is aligned with the latch.
2. Mark the screw holes: Use a pencil to mark the locations of the screw holes through the strike plate onto the door jamb.
3. Drill pilot holes: Drill small pilot holes at the marked locations to make it easier to drive the screws.
4. Attach the strike plate: Place the strike plate over the pilot holes and drive in the screws. Make sure the strike plate is secure and will not move when the door is opened or closed.
5. Test the latch: Close the door and test the latch to ensure that it latches onto the strike plate smoothly. If necessary, adjust the strike plate position or the latch bolt to improve the fit.
6. Install security features (optional): For added security, you can install a deadbolt or other locking mechanism to the door. Follow the manufacturer’s instructions for proper installation and use.
| Security Feature | Installation Tips |
|---|---|
| Deadbolt | Install at least 6 inches above the floor, preferably close to the doorknob. Use a strike plate with a reinforcing plate on the jamb. |
| Chain lock | Install near the top of the door, allowing a small gap when the door is open. Choose a chain with a thick metal link for maximum strength. |
| Door reinforcement bracket | Mount on the inside of the door frame near the hinges and strike plate. Provides additional strength and prevents the door from being kicked in. |
Finishing Touches
Once your door is hung, there are a few finishing touches to complete the installation.
