Trimming the caulk
Trim the hardened caulk flush with the
siding using a razor blade.
All houses gradually accumulate
holes in their siding from fasteners
and from phone and cable lines.
The only way to repair these holes perfectly
in vinyl or aluminum is to replace the
entire piece—a repair that ranges from
challenging in vinyl to almost impossible
in old aluminum.
For an easier, nearly-as-good fix that
keeps water out and is almost invisible
from several feet away, fill the hole with a
color-matched caulk. Home centers don't
usually stock it, but siding wholesalers
that sell to contractors carry caulks specifically
blended for dozens of different
shades of siding. If you know the manufacturer
and color name of your siding,
you can get the exact blend developed for
that shade. Otherwise, bring a sample
piece or take a photo and ask a salesperson
to help you match it.
Before filling the hole, wipe the siding clean. Squirt enough caulk into the hole to
fill the area behind the hole. Avoid smearing
excess caulk all over the surrounding
siding—the less you get on the siding, the
less obvious the repair will be. Once the
caulk is fully cured (which could be several
days, depending on the type), trim it
even with the siding with a razor blade.
To avoid making holes, use vinyl
siding clips instead of fasteners to
hang decorations. They're sold at suppliers or online.
