Gather the Necessary Tools and Materials
Installing a prehung interior door requires basic home improvement skills and some specialized tools. Before you begin, make sure you have the following items on hand:
- Prehung interior door
- Carpenter’s square
- Level
- Hammer
- Screwdriver
- Power drill
- Shims
- Door hinges
- Caulk
- Door handle or knob
Preparing the Door Frame
Before you can install the prehung interior door, you’ll need to prepare the door frame. Measure the width and height of the door opening. Then, use a carpenter’s square to check the frame for squareness. If the square doesn’t fit properly, use shims and a hammer to straighten the frame. Once you’ve made adjustments, use a level to ensure the frame is plumb and level. If the frame is not level, you’ll need to make further adjustments using shims.
Installing the Door
Now that the frame is level and square, you can begin installing the prehung interior door. Start by setting the door in the frame. Then, use a power drill to secure the hinges to the frame. Next, use a screwdriver to secure the door handle or knob to the door. Finally, use caulk to seal the edges of the door.
Finishing Up
Once the door is installed, use a carpenter’s square to recheck the frame for squareness. If the square still doesn’t fit properly, use shims and a hammer to make additional adjustments. Finally, use a level to recheck the frame for plumb and level. Congratulations, you’ve now successfully installed your prehung interior door!
