Frequently Asked Questions

Why won't my window stay up?

Answer: The Sash may have come out of the “shoe”. Which is very easy to fix. See photo to identify the “SHOE”, make sure your shoe isn’t stuck at the bottom of the window frame. IF it is, open your window, remove the sash. The sash is the window that operates (see picture). Take a flat head screwdriver, tap it under the shoe. Raise the shoe about 3 inches from the bottom of the frame. Put the sash back in, and close the window. See video below.

Cause: The sash may come out of the shoe if the window was taken out, perhaps for cleaning or just reviewing the functionality of the window.

How To Adjust The Shoe:

Window Shoe. The shoe is what holds the sash in the window frame.
Window Sash. The window sash is the operating window. Sash is shown open for cleaning.

WHY do I have condensation?

Each winter sees more and more homeowners vitally interested in solving window condensation. Window condensation is not a happy interest because of bad experiences, which range from irritating to downright expensive.

It may strike you as odd, but the growing condensation problems of the nation are caused by progress. If you have trouble with window condensation, it’s probably because you live in a “tight” modern home that you can heat for a fraction of the money it took to heat the house your parents lived in—a home that’s cleaner and more comfortable besides! Your condensation problems also result from use of labor-saving appliances that make life easier than it used to be.

This article explains the moisture problem of the “tight” home. It offers suggestions for curing condensation problems in existing homes and provides additional suggestions for you who are planning a home. You unquestionably will build a “tight” home, and there are more things you can do to prevent excessive moisture when you build than can be done in a home where the problem already exists.

Control Humidity
A few things can be done to control humidity, such as turning off humidifying devices, opening the fireplace damper so moisture can escape, keeping windows slightly ajar, or opening them for a few minutes each day. You may also air out the kitchen, laundry rooms, and bathrooms after they get steamed up. Some other steps that can help to reduce humidity are covering pots while cooking and using gas or electric furnaces.

Some amount of temporary condensation will occur for three main reasons: new construction, humid summers, and sudden drops in outdoor temperature. New building materials contain a lot of moisture, although the first heating season should dry things up. During a humid summer, a house absorbs moisture and again should dry up with the first heating season. No cure is available for temporary condensation; it just needs time to run its course.

Proper ventilation is important when dealing with condensation, and a couple of positive steps can be taken here. Make sure the louver doors in the attic and the basement crawl space are open and adequately sized. Run kitchen and bathroom ventilating fans for longer periods of time than you usually do. Some other simple steps may help, such as making sure vents are clean, venting all large appliances to the outside, venting the crawl space, using small fans to circulate air, and not storing firewood indoors.

Energy-efficient windows and doors made with low E II or argon coatings are designed to maintain the temperature difference between indoors and outdoors. You can also install double or triple glazed windows. Just remember that windows do not cause condensation–it is caused by the amount of humidity in the home. Therefore in some cases, the expense of new windows may not be justified.

What the Better Business Bureau says!

Tell tips #421: Condensation on Windows Condensation is visible evidence of excessive moisture in the air. It may appear as water, frost, or ice on the room surface of windows and doors. The warmer the air, the more water it can hold. This means that the air in the center of any given room will hold more water than the air adjacent to the window or door walls, since this area is always colder. When the warm moisture-laden air moves toward the cooler window or door wall, it becomes cooler and could not hold the moisture it held when it was warmer. Therefore, the moisture is dropped and appears as water on the glass and frames of windows and doors. This occurs more frequently during the winter months, because of the extreme difference between the inside and outside temperatures. If you wish to avoid condensation during the winter months, when the average outdoor temperature drops to 35 degrees or less, it would be wise to maintain a 25 to 35-degree relative indoor humidity.

Ventilation is a very effective way to remove excessive moisture from the air, which is why old poorly insulated houses with single glazed windows often times do not have condensation problems. This is because the air is changed by infiltration around the windows, vents, and other openings. Newer homes which are constructed to meet current insulation standards and energy conservation requirements; or older homes which have been newly insulated through the addition of added attic or basement insulation and installation of prime windows with dual or triple glazed glass, are now so airtight that they present a new problem.

All homes will on occasion have temporary condensation, which is the result of one of three occurrences:

  1. New construction or remodeling. Building materials contain a great deal of moisture. As soon as the heat is turned on, this moisture will glow out into the air and settle on the windows and so on. This will usually disappear following the first heating season.
  2. During humid summers, houses absorb moisture. This will be apparent during the first few weeks of heating, and then the house should dry up.
  3. Sharp, quick, and sudden drops in temperature, especially during the heating season will create temporary condensation problems.

If you have an existing moisture or condensation problem, do not count on correcting it merely by installing new windows. Windows do not cause condensation; therefore, windows cannot cure condensation. However, an energy efficient vinyl replacement window with Super Spacer technology, Argon gas, and Low-E glass helps to greatly reduce condensation.
