What changes the right cleaning schedule?
Distance from salt water, prevailing wind, irrigation overspray, tree cover, construction dust, and the direction your glass faces all matter. A protected Palm City home and an exposed Hutchinson Island condominium should not be placed on the same schedule.
A useful Treasure Coast rule of thumb
Start monthly for exposed exterior glass, every two months for a typical residential exterior, and quarterly for interior panes. If the view looks hazy before the next appointment, shorten the interval. If it still looks excellent, extend it.
Why exterior-first service is usually enough
Salt, pollen, rain residue, insects, and landscaping collect outside much faster than inside. An exterior-only visit keeps the view clear without requiring anyone to be home, while interior service can be added when fingerprints and household film become noticeable.
How to tell salt film from irrigation staining
Salt film usually looks like an even haze and releases during routine cleaning. Irrigation minerals tend to form repeated white dots, arcs, or cloudy bands on the lower part of the glass. If those marks remain after ordinary soil is removed, the pane may need a separate hard-water buffing assessment rather than another standard clean.
Screens and tracks affect what you see after cleaning
A dusty screen can soften the view through newly cleaned glass, while debris in a standard track can move back onto the sill after the first rain. Pro Exterior includes standard screens, visible frames, and standard window tracks with the selected window cleaning so the finished view is not undermined by the parts immediately around the pane.
Build the schedule from the first return of haze
After a professional clean, note when the most exposed pane first loses contrast. That single observation is more useful than copying a neighbor’s schedule. Use the ocean-facing slider, irrigated front window, or shaded pool-area glass as the indicator, then place exterior service just before that condition normally returns.
