Most generic window cleaning guides tell you to clean windows in spring and fall. That's fine for Maine. In Central Texas, the seasonal pattern is completely different — and if you're following generic advice, you're probably scheduling your cleanings at exactly the wrong time.
Here's the local calendar that actually makes sense for Round Rock, Austin, Cedar Park, Georgetown, and surrounding areas.
January–February: Cedar Season — Wait, Then Clean
Central Texas cedar (technically Ashe juniper) pollinates from December through February, and it is relentless. At peak season you can watch a yellow cloud roll across the Hill Country. That pollen settles everywhere — including on window glass, screens, and frames.
Our recommendation: Do not schedule a professional cleaning until cedar season has fully passed. Cleaning during peak cedar just means you'll be cleaning again in two weeks. Wait until late February or early March, after a good rain has washed the last pollen wave off the trees, then schedule your first cleaning of the year for maximum effect.
March–May: The Best Window Cleaning Window of the Year
Post-cedar, pre-summer heat, regular spring rains washing road dust — this is the ideal cleaning period for Central Texas windows. Temperatures are mild, humidity is moderate, and cleaning solutions work at their best (extreme heat causes solutions to flash-dry before they can be properly worked).
This is our busiest season for a reason. A thorough March or April cleaning removes the full winter buildup: cedar pollen, winter grime, and any mineral deposits from fall irrigation cycles.
June–August: Summer Heat & Dust — Clean Before, Not During
Texas summers are brutal on windows. The combination of extreme heat, drought-driven dust, and heavy irrigation use means windows accumulate mineral deposits and dust film rapidly from June onward.
Cleaning is still perfectly effective in summer, but schedule it for early morning or late afternoon — not midday. Cleaning solutions (and even pure water) can flash-dry on 100°F glass before they can be properly wiped, leaving streaks. Professional window cleaners adjust technique for summer, but the physics still favor cooler glass.
If you're on a quarterly schedule, late May or early June catches the end of spring and before the worst of summer heat.
September–November: Fall Refresh Before the Holidays
October through November is the second-best cleaning window in Central Texas. Heat breaks, rains return, and you want your home looking great for the holiday season. This is also when live oak drip peaks — the sticky tannin residue that oaks release in fall that leaves a yellowish haze on glass and frames.
A fall cleaning removes summer's mineral buildup and oak tannin drip before the holidays and positions you well heading into cedar season again.
December: Pre-Holiday Touch-Up if Needed
If you're entertaining, a quick touch-up cleaning in early December before cedar season fully kicks in makes your home look its best. Just know that by late December, the cedar is already coming back.
The Optimal Schedule for Central Texas Homeowners
Based on local conditions, here's what we recommend for most homes in our service area:
- 2x/year minimum: March/April (post-cedar) and October (fall refresh)
- 3x/year ideal: Add a late May or early June cleaning before summer heat peaks
- 4x/year (quarterly): Best option for homes with heavy irrigation exposure or in new construction neighborhoods with active limestone dust
Quarterly service also prevents mineral deposits from ever reaching the "bonded" stage that requires expensive restoration work — making it the most cost-effective option over time. Schedule your window cleaning in Round Rock or check our full service area.
