How to Hang a Prehung Door: 13 Steps
Hanging a prehung door can be an easy and efficient way to install a new door in your home. Prehung doors come with the frame already attached, which can save you time and effort when replacing an old door or building a new room. In this article, we will walk you through the 13 steps needed to successfully hang a prehung door.
1. Gather the necessary tools: You will need a level, tape measure, hammer, nails, shims, utility knife, drill with screwdriver bits and screws.
2. Prepare the rough opening: Measure the height and width of the opening and make sure it is square. The opening should be about 2 inches wider and taller than the door itself.
3. Check for any obstructions: Ensure there are no pipes or wires in the opening that could interfere with the installation.
4. Remove the old door and jamb (if applicable): Carefully remove any existing doors or jambs before installing the new prehung door.
5. Position the prehung door in place: Stand the prehung door in front of the rough opening, aligning it flush with the interior wall surface.
6. Check for plumb and level: Place a level on both sides of the door frame to ensure it is vertically plumb. Adjust as needed by inserting shims behind the hinge side jamb until perfectly plumb.
7. Secure hinge-side jamb: Nail through jamb and shims into framing with appropriate nails, starting near one of the hinges and working upwards.
8. Check for square: Measure diagonally from top corner to bottom corner on both sides of the frame, ensuring that measurements are equal for a square frame.
9. Adjust strike-side jamb for plumb: Insert shims behind strike-side jamb at intervals, checking for consistency using your level. Continue until the entire strike-side jamb is plumb.
10. Test the door operation: Open and close the door to ensure it swings smoothly and latches without resistance. Adjust shims as needed to correct any issues.
11. Secure the strike-side jamb: Once satisfied with the door’s function, nail through the jamb and shims, securing it to the framing.
12. Trim excess shims: Use a utility knife to carefully trim any excess shim material flush with the door jamb’s edges.
13. Install casing and finishing touches: Install the door casing around the frame, then add any additional hardware (handle, lockset) according to manufacturer instructions.
Congratulations! You have successfully hung a prehung door in your home. By following these 13 steps, you’ll find that this task can be quickly accomplished with accurate results. Enjoy your newly installed door and the beauty it adds to your space.
