Blocking water drips
1 of 2
Loop the cable
A loop provides extra
length for minor repairs
or rerouting later. It also
forces water to drip off
the cable rather than
follow the cable into
the wall. A bushing
seals around the cable
and protects it from
the sharp edges of the
siding. Fasten the cable with clamps.

Use cable clamps to hold wire in place. Always insert feed-through bushings into holes through siding, and seal them with silicone caulk.
TV and Internet signals are the only
things coaxial cables should be bringing
into your house, but improperly
installed cables can let in water,
which can lead to rot and mold. So
the next time you’re trimming the
bushes, take a quick look where the
cable enters the house.
Cable should never run downward
and directly into your house.
Rainwater will adhere to the cable
and follow it right into your home.
Ideally, the cable should run upward
and then in. If your cable was
installed incorrectly, contact your
service provider and voice your concerns.
If the provider refuses to fix
the problem, see if you can reroute
the cable in order to gain a couple of
feet. Try to avoid splices if you can.
They can weaken your signal.
If you’re installing new cable, loop the cable before it
enters the building. The loop will not only help shed the
water but also provide extra cable in case a mistake is made
A properly sized feed-through bushing will allow you
to drill a slightly larger hole so you can fish the cable in
without damaging it. Dab silicone caulk behind the bushing before pushing it into its final resting place.
