To get started with building the frame, get the right tools. Also, you must know the right measurements of the frame and the door. To avoid making mistakes when fixing the carport, you need to know two things: the rough opening and the finished opening. The left gap can be used for insulation.

The rough opening is the size of the opening before installing a frame. It is a bit bigger than the door. This allows room for installing the frame. The finished opening is the space you have after installing the frame. It is usually the same size as the garage door, if not smaller.

Нow to Frame a Garage Door Opening

1. Get your tools

Before you get started, collect all the needed tools. You need the following when framing a garage door jamb:

  • Tape measure
  • Pencil
  • Bandsaw
  • 2×6 inch lumber

The lumber you get should be twice the height of the garage door. You’ll also need lumber to cover the distance between the header and ceiling. Another option is to use garage door jambs in place of lumber. You have many options for the jambs, although wood is a popular choice. If you choose thick materials, the opening will be bigger.

2. Measure the rough opening

With your materials ready, the next step is to figure out the exact size of the rough opening. The aim is to have a rough opening that is bigger than the garage door. Take your tape measure and check the length of the distance from the floor to the rough header. This should be no less than 1 ½ inches longer than the height of the garage door.

The header should be at least 9 inches wider than the garage door. The width of the rough opening should be 3 inches longer than the garage door. Make sure you measure this between the right and left corners of the garage door and rough opening.

3. Frame the header

The frame on the header is sometimes referred to as the “head jamb.” This is the piece of wood that goes at the top of the frame of the garage door opening. Install the head jamb first since it provides room for the side jambs to rest.

To know the exact length of the head jamb, measure the width of the garage door rough opening. It should be 9 inches longer than the width of the garage door.

When you have the correct length of the jamb or lumber, you can place it on the header using nails. The frame should be big enough to cover whatever space between the rough opening and garage door.

4. Cut out the goal post

The next step is to prepare to install the goal post. The goal post is the jamb that moves from the floor to the ceiling of your garage. This is where the tracks of the garage door are attached to the interior wall. Again, there is an emphasis on making correct dimensions. The two jambs are placed on opposite sides of the wall next to the garage door.

Use your tape to measure the distance from the floor to the ceiling. When you’re sure you have the right length, trace it on the lumber of a PVC jamb, and cut out the two pieces you’ll need for the goal post. You can always trim the edges to make sure you have the perfect fit.

5. Install the goal post

Now place each of the jambs on each side of the garage door. Use framing nails to secure the goal post in position. The two pieces of the goal post should be installed on the inner surface of the garage door. Since these jambs go up to the ceiling, they will have to go past the head jamb.

6. Attach each side jamb

With the goalposts in place, the next thing is to attach the side jambs. First, measure the distance from the floor to the header. Cut out the two pieces of PVC jamb or lumber according to the measurements. The jambs run from the floor to the head jamb. The side jambs should be about ¼ an inch less the height of the garage door. This ensures that they are not placed directly on the floor.

Once you’re sure about measurements, secure the side jambs with nails. It is better to install double side jambs that will support the entire frame. Now measure the finished opening to make sure that it is the exact size as the garage door.

7. Attach the center bracket framing

The final step is to install the back framing on the interior of the garage. This goes from the head jamb to the ceiling. Measure the height from the ceiling to the head jamb. Cut out a piece of jamb or lumber and install it.

This piece of jamb is important as it provides a frame to attach the center bracket. The center bracket is connected to the spring system of the garage door.
