Below you will find helpful answers to some of the more common questions we recieve from our Window World customers.

Dropping Windows

Sometimes, especially after being moved during cleaning, a window sash can become disengaged from its balancer in the frame track, often referred to as the "shoe." When the window is open, this detachment will cause the sash to drop from its heightened position in the frame. Each sash has a pin on both ends that connects it to the frame; fixing the issue is as simple at guiding the pins back into their shoes.

How to fix dropping windows
  1. Insert a flat-head screwdriver into the indent of the exposed metal shoe and give it a quarter turn (the indent should now be perpendicular to the window frame)
  2. Keeping the screwdriver in the shoe, allow the shoe to guide you up the frame to a few inches under the sash
  3. Using the screwdriver, reset the shoe to the vertical position (the indent will be parallel with the window frame)
  4. Move the sash down to the shoe and tilt it in
  5. Balance the sash with one hand in the middle and push down the sides (where the sash connects to the frame) to lock the pin into the shoe
  6. Tilt the sash back and move it up a few inches to ensure the shoe is now engaged (the track should be empty)
  7. Lock the window

How to fix broken window locks

Please review the scenarios listed below to correct your locking problem.

Unable to lock the window

Unlock the window completely. Push the upper sash upward, as far as it will move and pull the lower sash to the bottom of the window. Once both sashes are in their proper positions you will be able to engage the lock.

The top sash has dropped from its pocket

Push the upper sash all the way to the top while at the same time pushing the lower sash down. NOTE: You may need an additional person to aid you. This should align and allow you to engage the window lock.

The sashes are not aligned correctly in the channel

Tilt each sash in as if you are cleaning the windows. Push both sashes firmly back into the window channel. This should align the sash and allow the window to lock properly.

Balance shoe is disengaged

If the balance shoe becomes disengaged from the sash, the window will not lock because it is misaligned. To correct this situation, please refer to the section on "Windows Dropping Down".

If the instructions listed above do not correct the problem, please call us for further assistance.

How to prevent window fogging and condensation

Household condensation, or "sweating", on windows is a result of humidity comes in contact with a cold surface such as a mirror or glass window, it turns to water droplets and is called condensation. This is perfectly normal and all homes will occasionally have some condensation on their windows.

Keep in mind that excessive window condensation, frost, peeling paint, even moisture spots on ceilings and walls can be signs of excessive condensation and possibly damaging problems in your home. We tend to notice condensation on window and mirrors first because they are not porous and moisture cannot penetrate these surfaces. This is an indication that you may have a moisture problem that needs to be addressed.

Note: Windows do not cause condensation

You may be wondering why you see more moisture now that you have replaced your old, drafty windows with energy efficient ones. It’s simple really, your old windows were drafty and allowed humidity to escape. Now that your new windows create a much tighter seal, the excess moisture is unable to escape and therefore collecting on your windows. Again, windows do not cause condensation, instead they prevent humidity from escaping and provide an easy surface for condensation to collect.

Where is the humidity coming from?

There are many common things that generate indoor humidity such as your heating/air unit, humidifier, showers, etc. Everything you do in your home that involves water, like mopping the floors, contributes to the problem.

The condensation you see on your windows is more likely to occur where the outside temperature is much lower than the inside temperature. The greater the difference the greater the opportunity for condensation.

Reducing humidity is the key to reducing condensation.

The best way to reduce condensation is to lower the humidity in your home. So, how much humidity is too much? The following table illustrates the recommended comfortable levels of indoor humidity during the winter months.

OUTSIDE TEMPERATURE INSIDE REMITIVE HUMIDITY
-20°F 15 to 20%
-10°F 15 to 20%
0°F 20 to 25%
+10°F 20 to 30%
+20°F 30 to 35%
(Indoor humidities can be measured with a humistat or psychrometer.)
Easy steps to controlling indoor humidity
  • Make sure all sources of ventilation to the outside are working. If bathroom exhaust fans, attic vents and laundry room vents are not working excess moisture is building up.
  • Air out your home periodically. Opening windows for just a few minutes a day lets excess moisture escape and the fresh dry air enter.
  • Check your humidifier setting. Make sure you are following the instructions for your humidifier.
  • You can even open your fireplace dampers to allow excess moisture to escape.
  • Do your best to not over-water your house plants.

Window Seal Failure & Glass Breakage

Windows that appear foggy could be suffering from seal failure, where outside air has penetrated the space between the two panes of glass and condensation develops. Unfortunately, once seal failure occurs, there is very little that can be done to repair the sash. Similarly, if the glass in a sash has been compromised, the best solution to maintain the integrity of the window is to replace the sash.

Window World customers have the peace of mind of knowing that they have an industry-leading warranty. If seal failure or glass breakage occurs, we can have a replacement sash specially manufactured to fit your window. Simply give us a call!
