Repairing Buckled Siding at the Joist
Vinyl siding sometimes becomes buckled between the first
and second floors of a newly built siding installation due to
settling and shrinkage of wet lumber and some framing
practices. Using “engineered” lumber for the joist greatly
reduces the chances of shrinkage and settling and can help
prevent buckling of siding. If, however, you do have a building
with this situation, here is a way to correct the problem using
aluminum starter strip.
With a zip-lock tool unlock the buckled panel from the panel
below by inserting the hooked end of the tool behind the
return leg of the buckled panel until the hook catches. Pull
down and “unzip” the panel.
Insert an inverted scrap piece of starter strip into the exposed
receiving lock of the lower panel.
With the scrap piece inserted into the lock, lay the upper panel
over the starter strip. The starter strip should be visible behind
the upper panel. Mark a line on the scrap piece where the
return leg of the upper panel meets the scrap piece.
Trim the starter on this line, saving the portion with the locking
edge.
NOTE: Cut the starter strip in shorter lengths to ease
handling and relocking.
Insert the trimmed edge into the lock of the lower panel. Begin
at one end and, using a zip-lock tool, pull the return leg of the
upper panel down to engage the upper panel with the
aluminum starter strip.
