Service overview
A clear plan for a cleaner result.
Clean glass improves natural light and presentation, but a complete window-cleaning quote must define more than the number of panes. Interior or exterior access, height, screens, removable storm units, tracks, paint or adhesive residue, hard-water deposits and surrounding surfaces all affect the work.
Zem confirms which sides of the glass are included and what can be reached safely with the approved equipment. Ordinary dust, fingerprints and environmental film are different from mineral etching, scratches, failed seals or construction residue. Those conditions may remain even when the glass is properly cleaned.
