How To Install Prehung French Patio Doors

Installing prehung French patio doors is a project that can be completed by most do-it-yourselfers with some basic carpentry skills. By following these step-by-step instructions, you can ensure a successful installation.

1. Prepare the Opening

Before you can install the new doors, you need to prepare the opening. This involves removing the old doors and frame, as well as any trim or molding around the opening. Once the opening is clear, you need to check to make sure that it is square and level. If it is not, you will need to make adjustments before you can proceed.

2. Install the Door Sill

The door sill is the bottom piece of the door frame. It is important to install the sill level so that the doors will open and close smoothly. To install the sill, simply place it in the opening and secure it with screws.

3. Install the Side Jambs

The side jambs are the vertical pieces of the door frame. They are installed on either side of the door sill. To install the side jambs, simply place them in the opening and secure them with screws. Make sure that the jambs are plumb (vertical) before you secure them.

4. Install the Head Jamb

The head jamb is the top piece of the door frame. It is installed above the side jambs. To install the head jamb, simply place it in the opening and secure it with screws. Make sure that the head jamb is level before you secure it.

5. Install the Doors

Once the door frame is installed, you can install the doors. To do this, simply lift the doors into the frame and secure them with screws. Make sure that the doors are level and plumb before you secure them.

6. Install the Trim

Once the doors are installed, you can install the trim. The trim is used to cover the gaps between the door frame and the wall. To install the trim, simply cut the trim to length and nail it in place.

7. Finish the Installation

Once the trim is installed, you can finish the installation by caulking the gaps around the door frame. This will help to keep the weather out and prevent drafts.
