1. Carefully slide the new door into the frame. Use shims to hold it in place if necessary. Take note of anywhere the door needs to be trimmed.
2. If the door doesn’t require trimming, skip this step.) Lay the new door flat and lay the old door on top. Make sure both are facing the same way. Use the old door as a template to mark where the new one needs to be trimmed. Use your oscillating saw to remove any excess and sand the edge.
3. Still using your old door as a reference, mark where the hinges and doorknob will go on your new door.
4. Trace the hinge markings with a utility knife. Using a hammer and chisel, carefully make notches inside the hinge markings. This will make removing the excess easier.
5. Gently scrape off the notches with your chisel.
6. Attach the new hinges to the door. Make sure they’re positioned to allow the door to swing in the right direction.
7. Attach the door handle and any additional locks.
8. Locate where the latch will be and, using the same method as steps 4-5, prep the area. This will ensure the latch is even with the door.
9. Install the latch.
10. Position the door in the frame and support it with shims if needed. Attach the hinges securely to the frame. Check the fit again before moving on.
11. Using the latch as a reference, mark the spot on the frame where the latch plate will go. Repeat steps 4-5 again to prep the area. Install the latch plate and make sure the latch fits smoothly.
