For most homes in Northern Virginia, DC and Maryland, professional window cleaning twice a year keeps glass clear: once in late spring, after the heavy spring pollen has settled, and once in the fall, after leaves come down and before the holidays.
Clean more often if your home is near heavy tree cover, construction or busy roads, if sprinklers spray the glass (which leaves hard water spots), or before an event, a listing photo shoot or a move.
A professional window cleaning from Green Zebra Exterior Cleaning covers exterior glass, with interior glass available as an add-on or on its own. Screens are cleaned and reinstalled, and sills and tracks are detailed. Skylights and hard water stain removal are available.
Pairing window cleaning with gutter cleaning in the fall is efficient: both happen once the leaves are down, in one visit.
