No matter which type of door you would like to tackle, Builder’s Discount Center  has all the items you will need. 

The Tools You Need to Install an Interior Door

There are a few important hardware items & tools you’ll need to successfully install your new interior door.

• Prehung door
• Level
• Shims
• Hammer
• Nail gun
• Utility knife
• Chisel
• Screwdriver
• Finishing nails
• Door lock installation jig (optional)

Start with measuring your door frame to make sure you purchase the correct size prehung door. Then remove the old door by taking out the hinge pins using a nail punch and hammer. Unscrew the hinge brackets from the door jamb and lift the door out of the frame.

It’s Easy When You Follow These Steps

Steps for installing an interior door:

1. Slide the prehung door into the rough opening.
2. Use a level to ensure the door is even. Add shims as necessary to adjust.
3. Once the door is level, nail the door frame to the studs using finishing nails.
4. Score and remove any excess shims with a utility knife.
5. If your new door isn’t pre-drilled, use the old door as a guide to mark hinge placements.
6. Use a chisel and utility knife to score and create mortises for the hinges. 
7. For the doorknob and latch, a door lock installation jig can be helpful. Use it to bore holes for the latch and lever.
8. Install the latch and lever following the manufacturer’s instructions.
