I clean windows for a living around the Nashville/Franklin area, and the question I get more than any other is “how often should I actually be doing this?” Figured I’d share what I’ve learned since it might save some of you money (or a headache).
The short version: there’s no universal answer, and anyone who gives you one is guessing. It depends almost entirely on your specific house. A few things that make a big difference:
• Trees. Mature trees around the house mean way more pollen, sap, and bird activity than an open lot. Shade is great, clean windows are harder.
• Pollen season. Y’all know how brutal Middle TN spring is. That yellow film hits glass hard for a few weeks.
• Hard water. The one people ignore. Sprinkler overspray leaves mineral deposits, and if they sit long enough they can permanently etch the glass. If your sprinklers hit your windows, fix the angle — seriously.
• Road/construction dust. Near a busy road, gravel drive, or active construction? Fine grit dulls glass fast.
• Sun exposure. South and west-facing windows bake on whatever’s sitting on them.
As a rough guideline most homes here do fine somewhere between twice a year (spring + fall) and quarterly if you’ve got heavy tree cover or hard water. Spring + fall is the sweet spot for the average house — clean off the pollen, then clear the summer buildup before winter.
One genuinely useful tip whether you DIY or hire out: don’t clean windows in direct sunlight. The cleaner dries before you finish and you get streaks no matter how good your technique is. Early morning or overcast is your friend.
Happy to answer questions about specific situations — hard water, screens, tracks, whatever. Not trying to sell anybody anything, just like talking shop.
