Jamb restoration removes lead paint and facilitates window operation

We find it useful (for the sake of defining the scope of a restoration project) to divide the window into four different sets of parts:

  • Exterior casing or window frame
  • Interior casing or window frame
  • Sashes and associated parts that contribute to functionality
  • Window jamb

The bulk of the work of window restoration focuses on the third set of parts listed above–sash and functional restoration.  But in almost all cases, the window jamb also needs to be restored in order to recover smooth functioning of the window.

The jamb consists of the sidewalls, top, and bottom (the sill).   This is the frame in which the sashes both sit and ride up and down. Here are the reasons we recommend window jamb restoration be included in any given window restoration project:

  • Improperly applied paint in window jambs is a major source of poor operation
  • This improperly applied paint also, then, is a major source for the creation of lead paint dust
  • Window sills are typically in need of some repair
  • It is difficult to properly seal windows with retrofitted weather-seals without removing paint from the jambs
  • As these images attest, jamb restoration is essential to the aesthetics of a window.  (I know it sounds “revolutionary,” but a pulley that isn’t slathered in paint is a good idea.  And yes, you did detect sarcasm in that statement.)
