Each Window Defoggers Dealer offers their own LIFETIME WARRANTY for both Commercial and Residential installations. The warranty period begins when the Window Medics restoration is completed. Transferring ownership is possible, as long as the original receipt is produced for warranty claims.

For Defogging Service each dealer shall provide:

  • Re-servicing of your window(s) if visible water, or water droplets, remains between your thermal window panes more than twelve (12) weeks after the Window Medics installation. A complete refund of the purchase price will be given if we are unable to remove the moisture from between your window panes within the first year after installation.
  • A replacement window is provided if window breakage should occur when the dealer performs window restoration work.
  • Replacing a one-way valve may occur if water droplets appear between the thermal windowpanes after a Window Medics restoration treatment has been completed

For Preventative Service each dealer shall provide:

  • A replacement window if window breakage should occur during the valve installation.
  • Re-servicing of your window(s) if visible water, or water droplets form in-between the panes.
  • A complete refund of the original price paid if visible water or water droplets appear after re-servicing.
