High-quality silicone rubber weather stripping permanently seals gaps around exterior doors, increases energy efficiency—and looks better than most other types of weather seals.
By the DIY experts of The Family Handyman Magazine:December / January 2011
This old door had damaged brass weather strip held on by hundreds of tiny nails. We
used a small pry bar to remove the nails and weather strip. For the best-looking job, fill
the nail holes and repaint the jamb before installing the silicone tubing
After cleaning the area with toluene, xylene
or MEK, apply a thin bead of silicone caulk
to the inside corner of the jamb offset. This
is where you'll add the new silicone tubing.
Press the tubing into the wet silicone caulk.
Leave it a little long and trim off the excess
with scissors. Butt the tubing at corners.
Keep the tubing clean and dust free before
installing it to ensure good adhesion.
Damaged weather stripping can allow a
lot of air to leak around old entry doors.
Several surface-mount solutions work
well to seal the cracks, but they're unattractive.
A better-looking alternative is
silicone rubber tubing weather stripping, available in several colors and diameters.

Before you order the tubing, close the
door and inspect the perimeter to see
how large the gap is between the door
and the frame. Measure and record the
size of the gap at three places along
both sides and at the top of the door.
Use the chart at conservationtechnology.com to choose the right size tubing
based on the size of the gap. Order different
diameters for each side and the
top if the gap sizes are different. If the gap varies along one edge, order progressively
larger sizes and insert the
smaller seal about 1/2 in. inside the
larger seal where they join. You'll also
need a tube of commercial-grade neutral-
cure silicone caulk, which you can
get from Conservation Technology.
With the new silicone tubing in place,
your old door will be as airtight as
modern doors at a fraction of the cost of
replacing the door and frame.
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
You'll also need scissors.
Avoid last-minute shopping trips by having all your materials ready ahead of time. Here's a list.
