If you’ve ever seen water building up inside the track of your sliding window and thought, “This can’t be good…” — this video is for you.
Hey guys, Sean with American Window Concepts! Today we’re breaking down how the weeping system works on modern vinyl windows and why seeing water in the track is totally normal during rain.
🌧 What You’ll Learn in This Video
Why water naturally gets inside the window track
How modern sliding windows drain water through the weep holes
Why weather stripping doesn’t stop water
What causes water buildup during wind-driven rain
The BIGGEST mistake homeowners make (putting a towel in the track!)
When you should be concerned and what to do about it
Your window’s weep system is designed to channel water from the inside track → to the outside of your home. Even perfectly installed dual-pane windows will collect some water when it rains — that’s just how the system works.
🚫 Don’t Panic!
Water in the track doesn’t mean your window is leaking. Don’t cancel trips, don’t stress during storms, and definitely don’t shove a towel in the track — that actually makes things worse.
Hey guys, Sean with American Window
Concepts and today we're going to talk
about once again the weeping system of
your new windows and what is the
function? Let's get into that.
We're catching some rains now. We're
getting into the season where rains are
coming and we're starting to get these
phone calls from customers who are
saying,
>> "Hey, I have water building up in my
track where the window is sliding. I
think this is not working for me. Like,
this is not good." And I have to go out
and either inspect the window myself or
show them videos of what the function of
the weep hole is on the outside of the
vinyl frame. Any kind of frame that has
a dual pane glass unit is going to have
a weeping system in the channel to allow
for water to get from the inside of the
track to the outside of the home. So
when people are saying, "Well, why is it
that water is getting in here in the
first place?" And I would say to them,
well, your old window would allow that
as well. Unless it's a wooden window
that's a single hung or double hung,
then you're not going to have that
issue. But with these style windows, any
kind of slider window systems, even
single hungs and double hungs of today
are going to have an area where the
window goes into the frame itself and
closes. is the weather stripping presses
against the main frame, but you're still
going to have water that comes from
beyond the screen and drops inside the
window track. Weather stripping that is
on the slider side, whether it's a
single hung or a single slider, it's
going to stop a little bit of dust,
debris, things like that, but it's not
going to stop water. And even the dust
and debris that gets stacked on top of
that weather stripping at the bottom of
the slider is still going to fall into
the track. You have to maintain your
windows regardless. You're going to get
more water in the track if you have
winddriven rain. The little wee hole
here can get overwhelmed. Sometimes the
natural reaction of a homeowner is when
they start to see water pulling up
inside this window track. The first
thing they do is panic. Go grab a towel
and shove that towel inside this window
track. Big big no no. When you do that,
you have already created a bigger issue.
Now, now it's going to be so easy for
that water to go up and over the
interior lip and onto your window sill
and from there floor. If you have water
building up in your track, do not panic.
The only time I would say is to panic is
if it's just overflowing and you haven't
done anything. There's a very good
chance that the frame itself wasn't
punched correctly. All right, mistakes
can happen. It's very, very rare, but it
can happen. When you see water, do not
fret. It's going to be okay. I don't
want you to cancel trips because, oh,
rain's in the forecast and we can't
leave these windows unattended because
we're afraid that water's going to come
into the house. It's not going to happen
every time there's a rain. It's just
whenever you have torrential rains with
wind. When those happen, yes, you will
see some water building up in the track.
And that's okay. It's fine. Just let it
do its job and everything will be just
fine. Anyways, I hope this helps make it
a great day. Before you click off this
