How Often Should You Pressure Wash in North Texas? (A Seasonal Guide)
North Texas weather doesn't give your home's exterior much of a break. Between spring pollen, summer heat and dust, fall leaf tannins, and just enough winter humidity to keep algae going year-round, most homes here need exterior cleaning more often than the “once a year” advice you'll find online. Here's a realistic schedule broken down by surface and season.
The General Rule of Thumb
Most hard surfaces — driveways, patios, walkways, pool decks — hold up well to once or twice a year in our climate. Softer surfaces like roofs, siding, and fencing usually only need attention once a year, though shaded, north-facing areas that stay damp can need a closer eye.
The bigger factor than a fixed calendar is what's actually growing or building up on the surface. Algae, mold, and mildew spread fastest in humid shaded areas; dirt, pollen, and rust stains build up faster in high-traffic, high-sun areas. Both call for cleaning — just on different timelines.
Spring (March–May)
Spring is when North Texas gets hit hardest by a combination of heavy pollen, sudden rain, and warming temperatures — exactly the conditions algae and mold need to take hold on roofs, siding, and shaded patios. This is the most common time of year for us to get calls about black streaks appearing on roofs seemingly overnight.
What to check: roofs, siding, fences, and any shaded patio or walkway areas. Why now: getting ahead of algae growth before the summer heat sets it into the surface makes it much easier — and safer — to remove.
Summer (June–August)
Texas summers bake driveways, patios, and pool decks with dust, tree pollen residue, and mineral deposits from sprinklers and pool splash-out. Heat also makes stains — oil, rust, tannins — bond more stubbornly to concrete and stone the longer they sit.
What to check: driveways, pool decks, patios, and outdoor entertaining areas. Why now: this is peak pressure-washing season for hard surfaces — the durable ones that can handle high-pressure cleaning without damage.
Fall (September–November)
As leaves start dropping, tannins from oak and other trees stain concrete and stone surfaces, especially in yards with heavy tree cover — common throughout Double Oak, Flower Mound, and Argyle. Fall is also a good time for a pre-winter roof check, since North Texas's brief but real winter humidity can let moss and algae continue growing quietly through the cooler months.
What to check: driveways and patios under trees, gutters, and roofs. Why now: clearing leaf buildup and tannin stains before winter prevents them from setting in over several damp months.
Winter (December–February)
Winter is typically the slowest season for pressure washing demand, but it's not a season to ignore your exterior entirely. North Texas winters are mild enough that algae and mold don't fully go dormant, especially on north-facing roofs and shaded siding that don't get much direct sun to dry them out.
What to check: roofs and siding in consistently shaded areas. Why now: if you're planning a spring project — a patio refresh, pool deck resurfacing, exterior painting — winter is a good time to get a cleaning done first so the surface is ready.
A Simple Seasonal Schedule
Driveways, patios, pool decks: clean in late spring and again in late summer or early fall
Roofs and siding: soft wash once a year, ideally in spring before algae season peaks
Fences and screened enclosures: once a year, or as visible buildup appears
Shaded or north-facing surfaces: check twice a year — they hold moisture longer and grow algae faster than sun-exposed areas
When to Skip the Calendar and Just Look
Schedules are a helpful starting point, but the real signal is what you see: black streaks on a roof, green or gray film on a patio, a driveway that's visibly darker than when it was installed. If any of that shows up outside the schedule above, it's worth cleaning regardless of the season.
