How Often Should You Clean Your Windows in South Orange County?

Ask ten neighbors how often they clean their windows and you'll get ten answers, from twice a year to whenever it bothers them. They're all partly right. The honest answer depends on where the house sits, what's growing near it, and how much water ends up on the glass.

Four things that dirty glass here

Santa Ana winds, mostly in October and November, carry dry dust and grit down from the hills. It lands as a fine tan layer that feels gritty if you wipe it. A single windy week can undo a cleaning from last month.

In summer, the marine layer is the culprit. The damp morning air leaves a thin film on glass, and the dust it picks up bonds to it when the sun burns off the cloud. That film doesn't look like dirt. It looks like glare, a faint cloudiness that gets worse when the sun is low.

If you live near the coast, in Laguna Niguel, Dana Point, or San Clemente, salt mist joins the mix. It's invisible in the air, but it settles on the glass and gathers dust more readily than a clean pane does. Homes a few miles inland see less of it.

The fourth is hard water, and it's the only one you control. Sprinklers, hoses, and pool splash leave mineral spots that don't wash away with the next rain. They stay and build.

How to tell it's time

Skip the calendar for a moment and look at the glass. Stand inside and look out toward a bright sky, or check from outside in low afternoon light. Haze, streaks, and spots show up clearly in that angle, and they're nearly invisible at noon.

Big picture windows and tall entry glass show haze sooner, simply because there's more surface to catch the afternoon light. A large window that looked fine last month can look cloudy today with nothing changed except the angle of the sun. Here are the signs to watch for.

• Spots or a fan-shaped pattern on the lower panes, which points to sprinkler water.
• A cloudy glare on sunny mornings, which points to marine-layer film.
• A gritty feel or tan tint after a stretch of wind.
• Dust or dark residue collecting in the window tracks and on the screens.
• A noticeable change when you look at a freshly cleaned neighbor's house.

Try one quick test: run a finger along the lower corner of the glass or the bottom of the track. If it comes away gray or tan, you're past due. Tracks and screens are worth checking separately. They gather dust and debris out of sight and can keep a clean window from looking clean. Every visit from Alan's Cleaning includes the screens and tracks for that reason.

A starting schedule

For a typical inland home, two cleanings a year is a sensible starting point: one after the Santa Ana season in late fall, and one in spring before the marine layer settles in. Coastal homes, and any house where sprinklers reach the glass, tend to want a little more attention. A home with a lot of tall trees or heavy dust near a construction site may as well.

Some people prefer an annual visit and a quick wipe-down in between, and that's fine too. The point is to catch the film and the spots before they harden. Fresh buildup comes off easily with purified water. Buildup that has sat for years takes more time, and some of it can't be reversed.

What it costs around here

Alan's Cleaning publishes its window cleaning range for Laguna Hills. Most homes run $150 to $400, depending on window count and stories. Smaller homes with 10 to 15 windows typically start around $150 to $175. Larger two-story homes with 30 or more windows run $350 to $600 and up.

Those are ranges, not quotes. The exact flat-rate price comes from a phone call, and there's no hidden fee behind it. Alan gives free quotes and a firm number without sending someone out to your door first, for most services.
