How often should you pressure wash your home in Decatur, GA?

March 14, 2026

Humidity, tree cover, spring pollen and traffic film make buildup appear faster than many owners expect. Cleaning protects paint, siding and concrete as well as your curb appeal. For most homes, plan on a professional exterior cleaning about once a year, with a look around each season.

A practical schedule

Siding: every 12 to 18 months. Driveways and walkways: yearly. Decks and fences: every 12 to 18 months. Shaded, north-facing sides: check every 6 to 12 months.

Signs it’s time

Look for streaks, a dull film of pollen, slippery surfaces, dirt lines and weathered decking or fencing.

Why Georgia homes need it more

Warm, humid conditions encourage organic growth, and buildup left too long gets harder to remove.

Pressure washing isn’t always the answer

Siding and painted trim usually need a low-pressure soft wash, while concrete and stone can generally take traditional pressure washing.

The best time of year

Spring and fall are popular, but visible mildew or a slippery walkway is a reason to act whatever the season.

When to call a professional

Second-story work, delicate materials, stubborn stains and mixed-surface jobs are best left to a pro. Combining services can also get your whole exterior done in one visit.
