Repair of Siding

Replacing a Damaged Siding Panel

To remove a damaged panel, insert the hook end of a zip tool
into the lock between the damaged panel and the panel
above. Pull downward. This will allow access to the damaged
panel’s nail flange. Remove the nails securing the panel.
The nails may be allowed to stay in the wall if they are driven
flush with the substrate after the damaged panel is removed.
Remove the damaged panel and install a new panel. Then use
the zip tool to lock the new panel into the panel above.

Replacing a Damaged
Outside Cornerpost

Remove the face portion of the damaged post by scoring along
the outside corner of the receiving channel with a utility knife. It
may be easier if you first cut away part of the face of the outside
cornerpost to get better access to make these cuts.

Remove the nailing flanges from the new cornerpost by
scoring and bending until the flanges snap off. Be sure to
score along the inner corner of the receiving channel.

Lap the partial receiving channel of the new post over the
partial channel on the remaining nail flange. Pop rivet the two
receiving channel legs together as needed.

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 short 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.
