9 Most Common Window Installation Mistakes

Window installation is a complicated process requiring precision and attention to detail. Improper installation can cause a myriad of issues, from decreased energy efficiency to water infiltration. Here are 9 common window installation mistakes to be aware of.

Wrong Size Rough Opening

The rough opening of your window should be the exact size of the window, including the frame. If the rough opening is too small, the window won’t fit, and if it’s too big, it can lead to air infiltration, water infiltration, and energy loss.

Wrong Size Jambs

The jamb size should also match the size of the window, including the frame. If the jamb size is too small, the window won’t fit and if it’s too big, it can lead to air infiltration, water infiltration, and energy loss.

No Back Slope

When installing a window, the back slope should be considered. This is the slope of the window sill that helps direct water away from the window and outside. Without a properly-sloped back slope, water can enter the window, causing damage.

Poor Flashing Adherence

The window flashing serves an important role in window installation, helping to create a seal between the window and the wall to prevent air and water infiltration. Make sure to adhere the flashing properly to the window and wall for optimal performance.

Not Sealing the Nailing Fins

The nailing fins on the window should be properly sealed with an approved sealant. This helps to create a seal between the window and the wall to prevent air and water infiltration.

No Back Dam

The back dam is the portion of the window that sits on the brick mold. This is an important component as it helps to prevent water infiltration and air infiltration.

Other Common Mistakes

In addition to the above, there are several other common window installation mistakes that should be avoided, including:

  • Not using the correct screws
  • Not using enough shims
  • Not using the proper caulk
  • Not sealing the head
  • Not caulking the perimeter
