1. Check The Opening.

You need to make sure the door fits the opening. If the door is larger than the opening, it will not fit. If the door is considerably smaller, you may not be able to put enough wood between the jamb and the frame to make it work.

2. Level the Floor.

Checking the level of the floor is a critical step because if the floor is not level you will end up with a crooked door. Once you use a bubble level to find out how much the floor is off being level, you know what is needed to make it level.

3. Cut the Jamb on the High Side of the Door.

After you find the level, you need to cut the part of the jamb that will be on the high side of the door. This procedure will make the door level even if the floor is not.

4. Put Temporary Blocks on the Jamb.

Putting temporary blocks on the jamb will give you a way to hold the door in place while you are working on it. This step consists of four blocks capable of holding it to the door frame until you finish securing it.

5. Level Jamb Bottoms with Blocks.

After placing the door jamb in the frame, the next step is to level it using small blocks of wood as needed. To do this, you first bring back the bubble level to check to see how long will the jamb is. This part may require checking the Jamb level several times.

6. Nail the blocks on the jamb to the wall.

Nailing the blocks on the jamb to the wall supports it as you shim and nail it to the framing. These are temporary supports that hold the jamb in place well you are getting the door jamb properly aligned.

7. Check the door stop gap.

In this step, you check to see if the door is opening and closing properly. The door should contact the door stop evenly along its entire length. If it does not do so additional alignment of the door jamb will be required until the door works properly.

8. Shim Behind Hinges.

At this point, you remove the center screw evolve three hinges. After which, you slide wood behind the hinge. If the gap is more than three-eighths of an inch, you should add wood on both sides of the jamb. After you finish this, nail them with three two-inch fifteen gauge nails.

9. Add a Longer Screw to Each Hinge.

To further secure the door jamb add longer screws do each of the door hinges to secure them through to the frame. To make sure that you have not thrown the door jamb out of alignment open and close it after adding a screw.

10. Secure the Door Latch Side of the Jamb.

After this, you go to the other side of the door jamb and screw it down, you want to secure it by the door latch to make sure that it will handle even a hard slam. You should also secure it in several different places to give it strength.

11. Trim the Shims.

Once this is completed, it is time to trim the wood used between the door jamb and frame. That is the need to be cut back so that they are even with the door jamb and frame. This is necessary to get the excess water out of the way.

12. Remove the Temporary Blocks.

Once you have the door jamb secured, it is time to remove the temporary blocks. Removing this temporary support not only allows the door jamb to be held in place as it is supposed to be, but it clears up room for the rest of the process.

13. Attach the Trimming.

Attaching the door trimming; while largely cosmetic; is still an important part of the process. One practical use for it is that it does prevent airflow around the doorway, but its main purpose is to make the doorway look nice. Even plain trimming makes the door look better.

14. Secure the Door Latch Fixture.

Securing the door fixture helps make sure that the door will latch properly when it is shut. If the doorknob is not already installed in the door, this is the time to install it as well. Once the doorknob and fixture are attached, the door needs to be tested again.

15. Setup the Door Lever.

Just recheck that your door lever working or not. If looks good go ahead to the next step.

16. Test the Door for Problems.

The final step is to test the door to make sure that there are no problems. This will involve opening and shutting the door several times. The goal is to make sure that the door latches right, shuts evenly and that the job is truly done.
