Replacing Garage Door Trim |
Garage door openings use trim that
helps seal out rain and snow. The trim also acts as a stop for the
garage door, much like a window channel. Old wooden garage door trim
often rots over time requiring replacement. When replacing garage
door trim, choose a molded vinyl trim that lasts for years. This
garage door trim is a solid PVC with a vinyl flap that seals against
the face of the garage door. Replacing garage door trim with vinyl
trim eliminates the need for painting and offers a better seal than
standard wood trim.

Replacing Garage Door Trim
Measure the width of your garage door
opening with a tape measure. Next, measure the height of the door
opening. When purchasing replacement garage door trim, it is
necessary to buy two pieces for the height and one for the door
width.
Open the garage door. Pry off the
existing door trim with a small flat pry bar and hammer. It is often
less difficult to pry the trim from the side that meets the garage
door.
Close the garage door. Measure and mark
the opening jamb and header 1/2-inch from the face of the garage
door. Make marks every 12 to 16 inches. Open the garage door, and use
a straightedge to draw a line on the jambs and headers at your
1/2-inch marks.
Measure the top of the opening with the
tape measure, and cut a piece of vinyl garage door trim to the
measurement with a hacksaw.
Place the piece of garage door trim on
the garage floor with the face of the trim pointing toward you. Tap
trim nails at each end of the trim and the center of the trim with a
hammer. Tap the nails into the trim just enough to start them without
protruding through the backside of the trim.
Position the garage door vinyl trim
onto the header of the door opening with the vinyl flap pointing
toward the garage door. Align the solid part of the trim with the
trace line for the 1/2-inch mark. Drive the trim nails through the
trim and into the opening header. Drive several more trim nails along
the length of the vinyl trim, spacing them 6-inches from each other.
Measure the side jambs and cut pieces
of vinyl garage door trim to the measurements just as you did the
header piece of trim. Attach the side jamb trim to the opening jambs,
with the vinyl flap pointing toward the garage door and the solid
vinyl aligning with the 1/2-inch line.
Run a bead of silicone caulk around the
perimeter of the garage door opening where the trim meets the door
opening with a caulk gun.
Tips
Always install the top piece of trim
first. This helps prevent the vinyl flap on the side pieces from
getting trapped between the trim and garage door.
