How We Cure a Window

glass and window components are thrown into landfills every year.
2 million metric tons of greenhouse gases are produced making windows
The average life expectancy of an insulated glass unit is only 12
years, yet the components will last much longer.
2008 foggy window repair companies had saved over 250,000 windows
keeping approximately 3000 tons of glass out of landfills.
Manufacturing and installing new windows and glass for these
windows would have produced 5000 metric tons of greenhouse gases

process re-engineers the window to reverse the accumulation of
moisture. We drill small vents into the window,
through the glass or into the spacer bar of the window. Now
the window heats up and the air expands it starts to release the
moisture out of the window. Imagine a partially full water
with it’s lid tight in the sun. The water will never dry out
because the water has no where to go. However remove the lid,
put an attachment over the lid to make sure no rain, snow etc can get
inside. It will dry out and stay dry. We are
doing the same thing with a window. The key is (1) make sure
moisture has a place to go and (2) make sure water cannot get back into
the window, either through the vent we drill or though the seal.
positive aspect of this process is that the vents or membranes act to
pressure regulate the window. No longer will the heat put
external pressure on the seals or will the extreme cold cause the
window to be at a negative pressure and pull moisture into it.
benefits of this process: No mess from tearing
sash or frames to replace the window or thermal glass unit.
Reduce green house gas emissions by reducing the manufacturing and
transportation of glass and other window components, and
glass to fill landfills. The cost is
that replacing the glass or the window.
Why Windows Fail:
Thermal windows are manufactured to be a sealed unit. But it
is difficult to maintain a perfect seal. Manufacturing,
transportation and installation can destroy the seal. The
atmospheric pressure changes exposure to weather and the radiation from
the sun all act on that seal.
The majority of failed thermal glass units are found on the sunny side
of the property because of the extreme heat exerted on the
windows. In fact in recent testing the temperature
reached 160 degrees.
When it is very cold the pressure inside a window drops. The
window can even suck water into it. This especially happens
in high humidity areas like bathrooms. On one bathroom window
I worked on the window had filled up 2 inches of water. When
drilled into the spacer bar the window continued to pull air into the
window until the pressure had equalized to the outside air pressure.
Eventually because of this all windows will fail. The average
lifetime of a window is 12 years.

Handyman talks about this cycle that causes windows to fail]
Q. Can you clean the inside
surface of windows with water spots inside?
the window has a light haze, or small deposits that look like salt
crystals I can often clean them out. If the spotting gets
worse with river bedding streaks or white water spots, I
will not be able to clean them out.
Q: How long does it take (after the service is completed) for the
windows to be clear? i.e. the healing process ?
There is no exact answer to how long
it takes for a window to clear. There are a three major variables; how
large is the window, what is the window orientation to the sun and how
much water/moisture is in the window system. Honestly most
look worse when we finish than before we started because the cleaning
and rinsing process adds water to the system. However now the
can begin to heal or dry out. In the summer many windows dry
in two weeks. In the winter they may take 6 weeks to dry out.
Our warranty guarantees that all
moisture will be evaporated after 12 weeks.
Q: What is the R-Value of a normal Thermal pane and what would the
R-Value be after the process has been completed?
Generally speaking, in a standard thermal pane, the R value is in a
range of 2.5 to 4.3. The R value of the thermal pane will be restored
very close to the original R value of a new unit when the unit is dried
Q. Can you service glass doors or
other tempered windows?
I can't drill into tempered glass without breaking it.
However sometimes I can drill into the spacer bar area and
window. Normally if I vent a window thought the spacer bar I
won't do any cleaning or rinsing of the window, but the window will
dry out much faster.
you serevice low-e windows?
There are two major types of low-e coated windows:
coat and hard coat. Soft coat low-e windows are
delicate metallic coatings that easily oxidize. I cannot
low-e windows that have started to oxidize. However some
have a more durable coating. With hard coat low-e windows the
coating is baked on and is much more resistant to moisture and I often
can heal those.
Will window cleaning and cleaning chemicals used on the window (both
inside and out) have a harmful effect on your process and the membranes
No, normal window cleaning will not affect our process. You
should try to avoid putting harsh chemicals directly on the
Q: With the hole drilling and vent installation is there any visible
change to the window viewing area?
The access holes are discreetly positioned in the corners of the
insulated glass unit and generally out of the way of the main window
viewing area. In fact the upper hole and vent are generally covered by
blinds or drapes and not seen. Most
clients are very happy with the dramatic increase in the main view area
once we have removed the condensation and the small access holes and
vents almost disappear.
about windows that had argon gas when new?
With regard to the argon issue, while we concede that argon has many
very good qualities (i.e. it deadens sound and has better insulation
value that regular air), in our opinion, the argon has been out of a
failed window unit for a considerable period of time before
condensation formed in the window. So the best that we are able to do
is return the R value to what an original air fill window would have
been, slightly less than an argon filled window but considerably better
that a window filled with wet air.
