The Problem

  • Condensation between the patio-door panes had reduced visibility.
  • The sliding frame was still serviceable, so the work focused on the failed sealed glass unit.

How We Fixed It

  • Removed the fogged patio door glass unit.
  • Prepared the existing door frame.
  • Installed a clear replacement sealed glass unit without removing the frame.
