How to Frame a Garage Door Jamb

The garage door jamb usually extends from the floor to the header boxes’ underside on both sides of the opening. In some design versions, a piece of finished wood or ornaments bridges the bottom of the header. The door jamb is usually used to provide a stop for the external wall at the opening and a platform for the roller track or hinge. You can install and frame the garage door jamb through the following steps:


Erect a ladder on the side of the framed door. Next, measure the distance from the floor to the bottom of the header at the vertical frame’s outer edge to determine the door jamb’s height.


Place two sawhorses in parallel, about six feet apart. Next, lay two 2×8 pieces of lumber flat on top of the horse. Measure and mark each part of the front edge of the door jamb. 


On the side of the opening, place the adjustable square handle against the wooden frame’s outer edges, with the blade on the bottom side. Next, adjust the square blade so that it points into the garage.


Slide the square handle down until the blade touches the floor. The garage floor is slanted for drainage, so be sure to consider this when marking the door jamb to be cut. Adjust the blade so that it slides on the floor surface too.


Place the square handle against one side of the door frame. Next, slide the square to align the blade with your mark. Ensure that the square is in the correct position so that the toes (longer points) are on the mark. Next, mark the angle of the floor on the front of the door jamb. Repeat this step and mark the angle on the remaining door jamb.


Put on safety goggles and cut the door jamb to a certain length with a circular saw. 


Erect a door jamb on one side of the opening, lay it flat on the frame, and cut it at an angle on the floor. Adjust the side panels’ position so that the outer edge extends one inch from the wall frame’s outer surface. This provides a stop for the side panels. If the exterior wall is plaster, stucco, or masonry, place the edge flush with the frame.

Use a 20-ounce finishing hammer to screw in two 16d galvanized nails 3 inches from the top of the door frame. At this point, nails should be partially used to secure the door jamb in place. 


Plumb the door jamb vertically by clicking the inner or outer edge as needed. 


Drive in galvanized nails over 24 inches along the surface of the door jamb, and use the threaded end of a 3/8 inch bolt to secure the mail.


Install the second door jamb on the opposite side of the opening, using the same procedure as the first.
