How can I get rid of the condensation that forms
on my window panes?
The answer varies, depending upon whether the
condensation is on the Exterior Pane, the Interior Pane or Between
the Panes.
EXTERIOR PANE: Condensation on the outside of your windows
or patio doors may occur during spring and in the fall, usually when
cool nights follow a warm day. It is a result of moisture in the air
exceeding certain limits and the temperature of the glass falling
below the dew point in the air. Condensation on the exterior glass
panes is a natural phenomenon. This condensation will evaporate once
the day warms.
INTERIOR PANE:
On the edges or entire pane: Condensation on the inside of your windows
is a result of too much moisture in the air of your home. This condition
is common in new homes, where it may take months for the moisture
from paint and fresh building materials to dissipate. This condition
is also common in winter. Humidity levels in winter months should
no exceed 30-35%.
To maintain these levels in your home, you may want to:
· check your venting,
· use a dehumidifier to remove moisture,
· turn your humidifier on furnace down or off,
· turn on exhaust fans during showers, and
· allow ceiling fans to run and circulate the air.
Oval in center: An oval condensation ring on the interior glass surface
is an indicator that interior and exterior panes of glass have collapsed
toward each other. You need to repair or replace the window sash or
door panel.
BETWEEN THE PANES: When the seals along the outer perimeter
of glass fail and allow moisture to penetrate the space between panes
of insulated glass, your window or door will appear cloudy or fogged.
Please check and make sure the glass does not have chemicals or pollutants
on the outside surface. Once you confirm that the condensation is
between the panes, you will need to replace the window sash or door
panel.

Can scratched glass be repaired?
Typically, scratches in glass are the result of
debris during construction or dirt on the glass. If care is not taken
to lightly flush and remove the debris it could etch the glass surface
resulting in a scratch. As a guideline, if the scratch is deep enough
to catch the edge of a fingernail, it's too deep to remove. ^

What is the best method for removing
residue and other materials from glass?
There are a few procedures for cleaning stubborn
materials from glass.
IMPORTANT: Do not clean glass while it is exposed to direct
sunlight.
Cleaning with soap and mineral spirits:
- Apply mild soap, mild detergent, LEPTYNE® solvent, mineral
spirits or naphtha solvents to glass either by spraying or using a
clean, grit-free cloth or sponge saturated with cleaning solution.
CAUTION: When using solvents, do not use too much
solvent. Damage to the glazing or insulating unit seals can occur.
After cleaning the glass with solvents or mineral spirits, immediately
clean the frame with soap and water to prevent staining.
Follow solvent manufacturer's directions on label for toxicity, handling
and flammability warnings.
- Wipe the cleaning solutions on the glass in a circular motion,
applying light to moderate pressure. Approximately three to five passes
of the affected area may be required to remove the residue.
- Rinse the glass surface immediately with generous amounts of clean
water, removing the cleaning solution from the glass surface.
- Using a squeegee or clean, lint-free dry cloth, remove water from
the glass surface.
- If glass residue is still evident, repeat steps 1, 2, 3 and 4.
Cleaning with toothpaste
- Use a damp cloth and toothpaste for glue, pitch, and other less
harsh contaminates.
- Apply toothpaste to damp cloth and buff circular until clean
Cleaning with polishing compounds:
For harsher contaminants and scratches, there are polishing compounds
on the market such as cerium oxide, which works well for reducing
fine scratches and scuffmarks. Follow directions carefully and heed
all product warnings. ^ BACK

Your windows let in too much cool
air in winter and warm air in summer.
Old, worn-out windows are often leaky, which can
result in high energy bills during peak heating and cooling months.
The glass may be loose (in which case it should be re-glazed) or the
seal between the sash and frame may have weakened. The cost of replacing
failing windows is often dwarfed by overall household energy costs,
but we recommend replacing old single-pane windows with modern windows
that feature dual-pane Low-E glass for a substantial energy savings.
If your windows are in decent shape but still leak, consider applying
new weather stripping. It's easy to install and available at most
building supply stores. ^ BACK TO TOP
Your windows look ugly to you.
"Ugly" is a matter of taste, but let's
address three obvious causes:
Does the exterior color of the windows match the rest of the home?
If not, a simple repaint can solve the problem. If the windows are
obscured on the home exterior by unattractive storm window frames,
consider replacement windows with dual-pane Low-E glass instead.
Does the window style not match the home? Older homes usually feature
double-hung windows. Gliders and casements offer a more contemporary
approach. Consult an expert to see if you need a touch of architectural
authenticity in your home.
Does the window material seem artificial or cheap? If you don't like
the look of thick vinyl frames, replace them with natural wood that
can be painted or stained to match your interior. ^

Your windows won't open at all.
In some cases, a window may fail to operate simply
because of broken hardware. Replace the hardware and the problem is
solved, right? Some situations aren't so easy. Your window, for example,
may be painted shut -- and setting it free can be a painstaking process.
By carefully working a putty knife around the perimeter of the sash
and breaking the paint seal between sash and frame, you can often
undo the damage. For some extra leverage, try a small pry bar. In
extreme cases the interior trim may have to be removed. Be advised:
windows that are painted shut are often older and of poor quality.
Replacement is the best bet.
Operational trouble can also stem from a warped frame and sash. Warped
windows are usually caused by house settling, which skews the rough
opening where the window sits. In this case, the entire window must
be removed and the opening reframed and squared. After that, the most
common course of action is to insert a brand new window. ^

Your double-hung window won't
stay open.
If it's an older window, there's most likely a
problem with the connection to the sash weights. Older double-hung
window sashes are counterbalanced with heavy weights connected to
the sash on rope. As the windows age, the rope dries out and becomes
brittle, eventually breaking. If you decide to fix the problem yourself,
you can remove the interior trim to expose the fallen weight, replace
the rope and reinstall the trim. Newer double-hung windows often feature
in-sash balancers. If these break, follow the manufacturer's recommendations
for balancer replacement. ^ BACK TO TOP
Your windows don't open or close
easily.
For casement windows, the solution may be as easy
as cleaning and lubricating the operating hardware with a light oil
or dry silicone spray. Avoid lubricants or harsh abrasive cleaners
-- these will break down or collect dirt and grime. Gliding window
tracks also need periodic cleanings to maintain easy sash operation.
Otherwise, you may be looking at a warped frame and sash caused by
house settling, which can skew the rough opening the window sits in.
Here, we recommend removing the entire window and reframing and squaring
the opening. Then simply insert a new window. ^ BACK TO

Your windows are difficult to
clean.
Some homes must weather tough environmental conditions
by virtue of their locations -- such as areas of heavy industry, or
along the coast. Airborne particles abound in these environments,
and they stick to windows. That means frequent washing. Thankfully,
some window products are available to help ease the chore. Many double-hung
windows now feature tilt-in sash designs. This means the exterior
glass can be cleaned from the inside -- just tilt the sash inward.
If grilles cause cleaning headaches for you, consider ordering windows
with grilles built-in between the glass. It'll be easier to wipe the
windows clean.
^ BACK TO TOP
Your windows are falling apart
or rotting.
If a window is failing or on the verge of failure
-- leaking, sticking or falling apart -- it's time to replace it.
Choose a style that matches the other windows in your home. In many
cases, you can take the opportunity to do more than a simple replacement.
Why not enhance your home's look from the inside and out, and improve
your overall energy efficiency? Two windows side-by-side, called a
combination, can be replaced with a single picture window that frames
a stunning view or opens the room to more light. You can also enlarge
an opening to add more windows. Be sure to choose a replacement that
features the energy-efficiency of Low-E glass and the durability of
rigid vinyl cladding. ^
BACK TO TOP
Your windows are inconsistent
with the style of your home.
If your windows don't match your home's architectural
style, go ahead and replace them with a more appropriate style. It
can improve the look of the whole house. Older or more traditionally-designed
homes usually feature double-hung windows, while contemporary architecture
favors casement or gliding windows. Consult your architect for the
best fit. ^ BACK TO TOP
