Clean windows do something almost nothing else in home maintenance does: they change how your whole house feels in an afternoon. More light, clearer views, a home that looks cared for. But in Cache Valley — with our dust, hard water, sprinkler overspray, and long winters — glass doesn’t stay clear on its own. Here’s how often to clean it, why Utah is especially hard on windows, and what a professional cleaning actually gets you.

How often should you clean your windows?

For most Cache Valley homes, twice a year is the baseline — spring and fall. But the right rhythm depends on your surroundings:

• Twice a year (spring & fall) suits the average home and keeps glass consistently clear.
• Quarterly makes sense if you’re near a busy road, a construction site, or heavy tree cover, or if lawn sprinklers hit the glass.
• Monthly or on a custom schedule is common for homes where the view is the whole point — and for anyone who’d simply rather never think about it again.

Exterior glass takes the most abuse and benefits from more frequent cleaning; interiors can often stretch longer between visits.

Why Utah is so hard on your windows

If you’ve ever cleaned a window and watched it spot right back up, you’ve met Utah’s hard water. Our water is mineral-rich, and when sprinkler overspray or rain dries on the glass, it leaves behind calcium and lime deposits. Left alone, those hard water stains etch into the surface and become genuinely difficult to remove — a regular squeegee won’t touch them.

The good news: caught in time, professional treatment can remove up to about 95% of hard water staining and restore clarity. The sooner it’s addressed, the better the result — which is one more reason routine cleaning pays off. It’s also why adjusting sprinkler heads away from the glass is one of the best free things you can do for your windows.

What a professional residential window cleaning includes

There’s a real difference between wiping glass and cleaning a window. A proper residential window cleaning covers:

• Interior and exterior glass, washed and finished streak-free with professional squeegees.
• Frames, sills, and edges wiped down — no drips, no missed corners.
• Screens and tracks available as add-ons, so the whole window looks right, not just the pane.
• Hard water treatment where staining has set in.
• A final walkthrough to make sure every window meets the standard — yours and ours.

The 7-day rain guarantee

Here’s a worry we hear a lot: “Why clean windows if it’s just going to rain?” Rain itself is basically clean — it’s rain hitting dusty glass that leaves spots. Freshly cleaned windows are actually protected. And to remove any doubt, our work is backed by a 7-day rain guarantee: if rain spots your windows within a week of cleaning, we come back and re-clean the affected glass at no charge.

DIY or hire a pro?

Ground-floor windows are fair game for a Saturday and a good squeegee. The math changes with second stories, steep landscaping, hard water staining, and the simple fact that a streak-free finish is harder than it looks. Professionals bring the reach, the right solutions, and the technique — and hand you back the afternoon.

Frequently asked questions

Do I need to be home?
For exterior-only cleaning, no — as long as we can reach the windows. For interior work, someone should be home; our team wears shoe covers and treats your space with care.

Do you clean screens and tracks too?
Yes, both are available alongside your window cleaning and are the best way to get a truly clean-looking window.

Can you remove hard water stains?
In most cases we can remove up to about 95%, depending on how long the staining has set. The earlier we treat it, the better the outcome.
