How often should windows be cleaned in Austin?
For most Austin homes, twice a year: once in spring and once in fall. That schedule keeps glass clear and stops pollen, dust, and minerals from sitting long enough to bond to the surface or start etching it. Homes under heavy oak canopy, near construction, or with hard-water sprinkler overspray often need quarterly cleaning, because buildup there gets harder to remove the longer it sits.
The right schedule for your home depends on a few local factors. Here's how to think about each one.
Why do Austin windows need cleaning more often than you'd think?
Central Texas throws pollen, hard water, heat, and dust at your glass, often at the same time.
- Pollen comes in waves almost all year. Mountain cedar peaks from December through February, live oak from March through April, and ragweed carries into the fall. Each wave leaves a film on glass and screens.
- Austin's water is hard. When sprinklers mist a window, the water evaporates and leaves calcium and lime spots. Left for months, those spots can etch the glass.
- Heat bakes everything on. Long, rain-free summer stretches and strong sun cook pollen, dust, and mineral spots onto the glass.
- Construction never really stops. Fine dust from grading, framing, and concrete work travels well beyond the job site.
When is the best time of year to clean windows in Austin?
Late spring and fall. Timing matters as much as frequency. Clean in the middle of oak season and you'll have a yellow film again within days. Here's how the year breaks down:
| Season | What's hitting your windows | What to do |
|---|---|---|
| December – February | Mountain cedar pollen, winter dust | Book for after the holidays only if you have a reason, such as an event or listing photos. Otherwise wait. |
| March – April | Live oak pollen and tassels, spring storms | Hold off on a full cleaning until the oak pollen settles. |
| Late April – June | Leftover pollen, sprinkler season begins | Spring cleaning window. Clears the worst of pollen season before summer. |
| July – August | Heat, dust, sprinkler overspray | Exterior-only touch-ups are popular. Watch for new hard-water spots. |
| September – November | Ragweed, summer dust, fall leaves | Fall cleaning window. Resets the glass before the holidays and cedar season. |
Which Austin homes should clean windows quarterly?
Homes where buildup happens faster than twice a year can handle. Consider a quarterly schedule if any of these apply:
- Heavy tree canopy. Big live oaks and pecans, common in older neighborhoods like Tarrytown, drop pollen, tassels, and leaf debris on glass and screens all year, and shade keeps windows damp longer.
- Construction nearby. If a neighboring lot is being rebuilt, a common sight in Rollingwood and fast-growing Bee Cave, dust settles on your windows every week.
- Sprinklers that hit the glass. Each watering adds another layer of mineral spots. The longer they sit, the more likely they are to etch.
- Hillside and lake-view homes. Exposed lots in West Lake Hills and Lakeway catch more wind-blown dust and pollen, and their big view windows make every spot visible.
Do inside windows need cleaning as often as the outside?
Usually not. The exterior takes the pollen, dust, storms, and sprinkler spray, so it gets dirty much faster. Interior glass mostly collects fingerprints, cooking film near the kitchen, and nose prints from kids and pets. Those build up more slowly, though homes with young children or dogs that watch the street may notice them sooner. A common approach is to alternate: a full interior-and-exterior cleaning once a year, plus an exterior-only visit in between. Many two-story homes book exterior-only in summer and add interiors in the fall.
How often should commercial windows be cleaned?
More often than homes, because customers see the glass every day. Storefronts, restaurants, and offices with heavy foot traffic often clean weekly or every other week, while offices with less street-level glass may do monthly or quarterly. Casa Care offers weekly, bi-weekly, monthly, quarterly, and custom schedules for commercial window cleaning, with early-morning, evening, and weekend appointments.
What are the signs my windows need cleaning now?
If you notice any of these, it's time, whatever the calendar says:
- A hazy film that shows up when the sun hits the glass in the afternoon
- White spots or rings on lower windows near sprinkler heads
- A yellow-green coating on sills and screens after oak season
- Screens that look gray or clogged, or sliding windows that stick in dirty tracks
- Rooms that seem darker than they used to
Is it bad to wait too long between window cleanings?
Yes. Waiting makes the next cleaning harder, and sometimes the damage permanent. Hard-water minerals and grime slowly etch into glass, and the longer they bake in the Texas heat, the harder and more expensive they are to undo. Deep etching can't always be fully reversed. Regular cleaning is the cheapest way to protect your windows, which is why our maintenance plans exist. Our guide to removing hard-water stains covers what to do if spots have already set in.
How can I keep windows cleaner between visits?
A few small habits go a long way:
- Adjust your sprinklers so they water the lawn, not the glass. This is the single biggest way to prevent hard-water spots.
- Trim branches that touch or hang right over windows and the roofline.
- Keep gutters clear so overflow doesn't run down the glass during storms. See gutter cleaning.
- Don't rinse windows with the hose. Austin tap water dries with mineral spots and can make the problem worse.
What's the easiest way to stay on schedule?
Let a maintenance plan handle it. Casa Care's plans book the visits for you and discount each one: Bi-Annual (2 visits a year, 10% off each), Quarterly (4 visits, 15% off, with free track cleaning and priority scheduling), or Monthly (12 visits, 20% off). You'll get reminders before every visit, and if rain spoils the exterior results within 7 days, we come back and re-clean for free.
