  • Q: Why is my single hung window hard to open or close?
    • A: Balancers are a block & tackle pulley and spring system. Often construction debris and/ or silt will work its way into the mechanism over time. By removing the balancers and the debris and giving a light spray of silicone spray may resolve the problem.
  • Q: What are weep holes and what are the used for?
    • A: Weep holes are small cut-outs at the bottom of the window frame when looking from the outside-in. When the passage within the frame is clear of dust and debris, rain will automatically be lead towards the outside of the frame to make sure no water is entering the house. To clean the weep holes or to open the passage, simply use a small screwdriver and remove any visible debris and dust. If you have any more questions, please view our video library to find a properly cleaning instruction video.


  • Q: Why is the inside of my window damp when I touch the glass?
    • A: Condensation is a common occurrence in modern construction.

  • Q: Why is Champion’s window track system better?
    • A. As you can see, Champion Windows tracks are curved on the top rather than being flat. The reason behind this is, that a window cannot simply move out of the track or move in general. The Champion Windows track provides more stability and security for your windows as well as more ease to operate the Vent.
