Weather Proof A Garage Door Opening (4/5): Deep Door Trim

 

Thickening the edge with a quarter-inch strip brings the trim back to the door jamb while spanning the rain screen WRB

 

Before installing siding, we’re going to install door casing and corner boards. The trim is pre-rabbeted to accept the siding edges, making installation faster and adding a layer of overlap to the weather protection system.

Because the drainage mesh bumps the thickness of the wall out, Will needs to thicken an edge of the trim to return back to the door jamb—about a quarter of an inch. After laying a bead of exterior wood glue, Will uses the ol’ finger-spreader to assure a solid bond.

Before installing side casings, Ron seals the bottom edge of the against bugs and water. Now, they screw the casing to the wall. And build up the head casing.

(Turns out, Will moonlights as a video director!)

The head casing is assembled and installed in place. The corner boards are not rabbeted like the door casing because it would be impossible to install the siding, so solid corners are screwed into the framing—again, sealing the bottom against intrusion from stuff we don’t want in walls.

Next, we will install the siding and put the finishing touches on this tricky little wall section.
