When’s the best time to pressure wash your home’s exterior?
If you live in Northern Virginia, the answer is: it depends on the season, your home’s condition, and the kind of curb appeal you’re chasing.

Here’s the thing your home’s exterior takes a beating here in Northern VA. Spring pollen, summer humidity, fall leaves, winter grime it’s like your siding, walkways, and decks are under constant attack. And while pressure washing is the superhero that blasts it all away, timing it right makes all the difference.

At Lawn Theory, we help homeowners across Fairfax, Arlington, Reston, Leesburg, McLean, Falls Church, and beyond pick the perfect time to wash away dirt, mildew, and that “been through a storm” look. As a veteran-owned, local exterior cleaning company, we’ve mastered the art of pressure washing in our unique climate so your home looks sharp year-round.

Why Timing Matters for Pressure Washing

You can pressure wash anytime the temperature is above freezing, but certain times of year offer better results, longer-lasting cleanliness, and less risk to your home’s surfaces.

Pressure washing at the wrong time can:

• Shorten the lifespan of your paint or siding
• Leave streaks or water spots from rapid drying
• Mean you’ll be cleaning again sooner than necessary

When you choose the right season, your home stays cleaner for longer, your landscaping isn’t disturbed, and you get maximum bang for your buck.

Best Time to Pressure Wash Your Home’s Exterior in Northern Virginia

Spring – Post-Winter Revival

Spring in Northern VA is like pressing the reset button on your home. After months of snow, road salt, and gray skies, your exterior is ready for a refresh.

• Wash away winter grime, salt stains, and mold spores
• Remove pollen buildup before it stains siding and decks
• Prep your home for spring landscaping projects

Pro Tip: Book your pressure wash before spring planting your garden will thank you.

Summer – Mid-Season Shine

Summer is prime “show-off your house” season. If your home sees a lot of outdoor entertaining, a mid-summer wash keeps it picture-perfect.

• Great for removing dust, mildew, and algae buildup
• Perfect for driveways, patios, and pool decks
• Avoid the hottest midday sun mornings and late afternoons work best

Plus, a clean house makes your BBQ look even better.

Fall – Pre-Winter Protection

Fall is our second busiest season for pressure washing at Lawn Theory and for good reason.

• Clear away leaves, dirt, and debris before they stain or clog gutters
• Protect concrete, decks, and siding before winter’s freeze/thaw cycle
• Apply protective sealants for driveways or decks after cleaning

Think of it as winterizing your home’s curb appeal.

Winter – Proceed with Caution

Pressure washing in winter is possible, but it’s not for every day.

• Only wash during warmer breaks in the weather (above 40°F)
• Avoid washing before a freeze to prevent icy hazards
• Ideal for emergencies, like removing salt from driveways

We recommend booking winter washes only when absolutely needed.

Signs It’s Time to Pressure Wash – No Matter the Season

Sometimes, your home will tell you it’s ready for a wash:

• Visible dirt, grime, or mold
• Green algae or mildew streaks
• Stains on siding, brick, or concrete
• Slippery walkways or decks
• You can write your name in the dust

If you spot these signs, don’t wait for the “perfect” month, act now to protect your home.
