Best Time of Year to Pressure Wash Your Katy TX Home
Most national pressure washing guides will tell you to clean "in spring or fall." That's good advice for Boston or Denver. In Katy, where we go from oak pollen season to hurricane season to mountain cedar season without ever really getting a winter, the calendar is more complicated. Some months are great. Others are a waste of money.
Here is a Katy-specific month-by-month guide to when to schedule your home cleaning.
The Two Best Windows in Katy
If you want the short answer:
- Late February through April is the best window for an annual deep clean. Cedar pollen is winding down. Live oak pollen is just starting. Humidity is lower than summer. HOA spring inspections are coming up. Your home will look its best heading into the busy outdoor season.
- Late October through early December is the second-best window. Hurricane season is over. Summer humidity and pollen have eased. You're cleaning off six months of growth before holiday gatherings.
If you can only do one cleaning per year, pick the spring window. If you can do two, do spring and fall.
Month-by-Month Breakdown for Katy
January: Avoid (Cedar Pollen Season)
Mountain cedar (Ashe juniper) drops massive amounts of pollen across central and east Texas in January. Even though the tree itself is more concentrated in the Hill Country, the pollen blows hundreds of miles east and coats Katy homes. Cleaning in January means re-cleaning in February when the pollen finally stops. Save the money.
February: Mid-Month and Later Is Good
Cedar pollen winds down by mid-February in most years. From February 15 onward, conditions are good for cleaning. Temperatures are cool, humidity is moderate, and you're catching all the winter buildup before it has a chance to set in. This is the start of the prime spring window.
March: Excellent
One of the best months of the entire year. Cedar is done. Live oak hasn't started yet. The weather is mild. Daylight is increasing. HOA spring inspections are coming up in April and May, so cleaning in March puts you in compliance well before any violation notices go out. Most Katy homeowners book their annual visit for March.
April: Good (Live Oak Pollen Caveat)
April is mostly excellent, with one caveat: live oak catkins drop yellow-green pollen across most of Katy starting mid-April. If you have a lot of live oaks on your property, plan your cleaning for the first two weeks of April or wait until early May. The pollen will collect on freshly cleaned surfaces and look bad for a few weeks.
May: Excellent
Live oak pollen has settled, mountain laurel and pine pollen are easing, and humidity hasn't yet reached summer peak. May is the perfect time to do a complete property cleaning before the heat sets in. We typically book up for May about 30 days in advance.
June: Good (Watch for Storms)
June can work but Katy starts getting daily afternoon thunderstorms by mid-month. The morning hours are best. Humidity is rising into the 80% range. If you missed the spring window, June is a fine catch-up month.
July: Avoid
Peak heat (95-105 degrees), peak humidity (90% in mornings), and daily afternoon thunderstorms. Anything cleaned will get re-soiled within weeks because the bacteria and mold growth rate is at its annual peak. Crews can work in July, but the value per dollar is at its lowest. Save it for fall.
August: Avoid
Same as July, with the added bonus of being the start of hurricane season. Even tropical storms that don't make landfall deposit massive amounts of debris and runoff against home exteriors. Cleaning in August is almost always a waste.
September: Risky (Hurricane Season Peak)
Statistically, mid-September is the absolute peak of hurricane season for the Gulf Coast. Cleaning your home and then having a tropical storm roll through the next week is exactly what you don't want. We typically tell Katy customers to wait until October.
October: Excellent
Hurricane season is mostly over by mid-October. Temperatures drop. Humidity eases. The summer's accumulation of mold, pollen, and storm debris is at its peak and ready to be removed. October is the start of the fall cleaning window and one of our busiest booking months.
November: Excellent
Last leaves are falling. Holiday season is approaching, and most Katy homeowners want their property looking sharp for Thanksgiving and Christmas guests. November is one of our highest-volume months. Book at least 3 weeks in advance.
December: Good Early, Avoid Late
Early December is fine, but by mid-December cedar pollen season is starting to ramp back up. Holiday weather can be unpredictable. We typically wrap up annual cleanings by December 15 and don't recommend booking after that until February.
Special Cases That Override the Calendar
Selling Your Home
If you're listing your Katy home for sale, schedule a full property cleaning 5 to 7 days before listing photos and open houses, regardless of the calendar. The boost to curb appeal is worth the off-season scheduling. Read our Katy pressure washing cost guide for what to budget.
HOA Violation Notices
If you've received an HOA notice about exterior appearance, you typically have 30 days to fix it. Don't wait for the "perfect" season. Schedule the cleaning now. Read our HOA compliance guide for more on Katy-specific HOA rules.
After a Storm
After any significant tropical system or severe storm, plan on a cleaning regardless of the season. Storm debris, runoff, and water damage need to be addressed promptly to prevent permanent staining. See our Katy hurricane season prep guide.
New Construction Move-In
Brand new homes in Cinco Ranch, Cross Creek Ranch, Cane Island, or Elyson typically have construction dust, mortar splatter, and yard debris that should be cleaned within the first 60 to 90 days of move-in. Don't wait for spring.
What About Driveways and Sidewalks Specifically?
Concrete cleaning follows roughly the same calendar as house washing, with a few notes:
- Spring (March-May) is best because winter rains have pushed dirt and clay onto concrete and you want it removed before summer sun bakes it in.
- Fall (October-November) is good because summer storms and humidity have grown algae and mold in the concrete pores.
- After construction or yard work is non-optional. Concrete that gets dirt or mortar on it should be cleaned immediately, not on a schedule.

Katy Climate Quick Facts
Three things that make Katy's seasonal calendar different from anywhere else:
- Humidity averages 70%-plus year-round. Mold and algae never really stop growing. We don't get a true "winter break" like northern climates do.
- Hurricane season runs June through November. Six months of risk that can disrupt any cleaning schedule.
- Pollen comes in waves. Cedar (December to February), live oak (April), pine (May), pecan (May to June), ragweed (August to September). There's almost always something dropping.
The two windows that avoid the worst of all three: late February to early April, and late October to early December. Those are your optimal cleaning windows.
Frequently Asked Questions
Is summer too hot to pressure wash in Katy?
Crews can work in summer but quality is lower for several reasons. Surfaces dry too fast for chemistry to dwell properly. Workers tire faster in 100-degree heat. Daily afternoon storms disrupt scheduling. And the growth rate is so high that anything cleaned will look dirty again within weeks. Wait for fall if you can.
Can I pressure wash in winter in Katy?
Yes, except during cedar pollen season (mid-December through mid-February). Katy rarely gets freezing temperatures so cleaning is possible most winter days. But if you clean during cedar season, the pollen will recoat everything within a week.
How far in advance should I book?
For peak windows (March, May, October, November), book 3 to 4 weeks in advance. For off-peak months, you can usually get a same-week appointment. Spring HOA inspection time (April and May) gets booked up the fastest.
What if I have an HOA inspection coming up?
Schedule your cleaning at least 5 to 7 days before the inspection. This gives the surfaces time to fully dry and shows the cleaning is complete. Most Katy HOAs do spring inspections in March or April.
Should I do my whole property at once?
Yes, that's almost always the best value. Bundling roof, house, driveway, and walkways into one visit saves 15 to 20% compared to booking each service separately. It also means everything is on the same maintenance cycle going forward.
What about January cleanings for new home buyers?
If you just moved into a new Katy home in January, get a baseline cleaning right away regardless of cedar pollen season. You need a clean starting point to see what condition the home is really in. After the baseline, follow the standard seasonal schedule.
