Window Cleaning Guides
Everything you need to know about keeping your windows spotless, removing hard water stains, and hiring the right pros.
How Often Should You Clean Your Windows?
There's no single correct answer to how often windows should be cleaned — the right frequency depends on where you live, what's around your property, and what your windows are exposed to. Most homeowners default to 'never' or 'when it gets bad enough,' which usually means years between cleanings and glass that's significantly dirtier than they realize. This guide gives you a framework to set an actual schedule based on your specific situation.
Professional vs. DIY Window Cleaning: Which Is Worth It?
Window cleaning seems like one of those tasks that obviously doesn't need a professional — you have a bucket, some glass cleaner, and paper towels at home already. In practice, most DIY window cleaning produces mediocre results: streaks from cleaning solution residue, smears from low-quality cloths, and missed contamination on the exterior that standard spray products can't dissolve. This guide breaks down what professionals actually do differently, what it costs, and when DIY is genuinely sufficient.
How to Remove Hard Water Stains from Windows
Hard water stains are the most common complaint in window cleaning — and the most misunderstood. Those white spots and cloudy film on glass aren't dirt; they're mineral deposits, primarily calcium and magnesium carbonate, left behind when water evaporates and leaves its dissolved minerals behind. Standard glass cleaners don't touch them. Vigorous scrubbing makes them worse. But the right chemistry and technique removes them completely — unless they've etched the glass surface, at which point you're in restoration territory.
Window Cleaning Cost Guide: What to Expect in 2026
Window cleaning pricing is more variable than most homeowners expect — the difference between a 15-window single-story home and a 35-window two-story can be 3x the price, and coastal California and the Northeast cost significantly more than the Midwest for the same work. This guide breaks down exactly what drives pricing so you can evaluate quotes accurately, know when something is suspiciously cheap, and understand what scope differences between quotes actually mean.
Best Time of Year to Clean Windows
The best time to clean windows isn't the same everywhere. The right timing depends on your climate, your local pollen calendar, the precipitation pattern, and what you're trying to achieve. Cleaning in the wrong season — right before the heaviest pollen drop, or right as salt air season peaks — can mean your windows are noticeably dirty within weeks of a professional cleaning. This guide breaks it down by region and situation.
10 Questions to Ask Before Hiring a Window Cleaning Company
Window cleaning looks like a simple commodity service — show up, clean glass, leave. In practice, there's meaningful variation in quality, equipment, technique, insurance coverage, and scope that isn't visible in a price quote. The right questions before hiring reveal which companies will deliver professional results and handle problems correctly, and which are cutting corners on insurance, equipment, or training. Here are the ten questions that matter most.
