For most homes, a professional window cleaning every 6 to 12 months keeps glass looking clear and helps windows last longer. That's the baseline. Busy households and homes near busy streets need it more often.
If you live near construction, have young kids, or deal with hard water from sprinklers, plan on every 3 to 6 months. Dust settles on the glass, kids leave handprints, and mineral deposits bake in under the California sun — the longer they sit, the harder they are to remove.
Here in San José and the surrounding South Bay, the seasons matter too. Spring brings pollen that coats everything, and dry summer months mean dust builds up fast. Many of our customers book a cleaning in spring to clear off the winter rain residue, and another in fall before the holidays when guests are coming.
Watch for the signs: water spots that don't wipe away, a hazy film that returns after you clean, or screens that look gray with dust. Those all mean grime has built up on the glass and frames.
Between professional cleanings, wipe sills and tracks regularly, clean spot smudges with a microfiber cloth instead of paper towels, and trim landscaping back from windows. When it's time for a streak-free shine, call (408) 555-0133 for a free quote.
