Bow to install siding trim around door.

Nail the head moulding piece to the door jamb with trim nails. Either way to trim a door you need to bridge the gap between the door jamb the frame from on which the door is hinged and where the latch engages and the wall. A miter joint is where the ends of two pieces of molding are cut at equal angles 45 degrees for a square corner. So we used the miter saw to cut them and the same type of nails to install them.

This video shows the installation of siding j channel around doors and windows. We used pressure treated 2 x 4 s for the trim around the windows and the doorway and then we had to create trim corners for both the inside and the outside corners like the ones in the picture above. After a closed garage you can cut windows and doors and use a sheath masking tape to cover the tape to the windows and doors. Installing the trim now that the door is prepped the trim can be added.

This will provide a continuous barrier to water. Cut the trim so it is two channel widths longer than the opening s width. This is done with molding called casing. If we installed the trim after the siding we would have had to caulk a ton to fill in for the different levels the layered siding creates.

Cut the first miter on the head moulding piece. Make a mark before you cut another 45 degree miter with the power miter. Start at one end of the vinyl siding trim around garage door and hold straight down the garage and wake up when you fast to the wall. Install j channels at doors and windows and under roof eaves and rakes.

Then measure the length of the moulding from the inside point of the miter you just cut to the desired length.
