Steps of Installing Inside Door

The following are steps that will teach you how to install inside door.

Remove the packaging and inspect the door

The first step is to remove the packaging from the product and inspect it for damage. If there are any damaged parts, you will need to replace them before getting started.

Measure the opening of the jamb so that you can verify that you bought the right replacement product. If you don't know how to, read our article on how to measure a door jamb for insight.

Fit the door into the opening

Next on how to install inside doors, fit the new piece into place and adjust it until it is right where you want it to be. A pre-hung will go into the rough opening, while a door slab will go into the existing frame.

Install shims

Check each side of your installation to make sure it is level or else you may have trouble getting it to stay in place once installed. If necessary, shim with wood blocks or spacers until they are plumb and level.

Start nailing

Once you have gotten everything level and straight, nail through the frame, into the shims, and into the adjacent wall studs. Drive nails through each shim every few inches but don't drive them all through at once — this will ensure that the balance of the panels is not disturbed.

Cut the shims

Once you've determined that the new panel is properly hanging and swinging, it's time to cut the shims.

Install the trim

Now that the excess shims have been removed, you can install the new trim.
