Exterior Siding Installation Accessories

Unsure where to start? Shop Samples

Exterior siding installation accessories include corners, starter strips, J-channels and trim and are required for your siding installation.


A starter strip is required at the base of the installation to lock the first row of panels in place, flush against the structure.

You will need the length of starter strip equal to the lineal footage of the base of each wall. Please refer to the product specs for the length of the selected starter strip.

You will need enough J-channel to go around each side of every window, door frame and other protrusions.
