How Often Should You Pressure Wash Your House in Florida?

In a lot of the country, washing the house is a once-every-few-years chore. In Central Florida it's not. Our climate does everything possible to grow algae, mildew, and mold on your siding, and the honest answer to "how often" is more often than you'd think.

The general timeline

For most Lakeland homes, plan on a house soft-wash every 12 to 18 months. But that's an average, and where the growth sits on your house matters more than the calendar:

• Shaded and north-facing walls: these barely see direct sun, stay damp, and grow that green-black film fastest. They often need attention closer to the 12-month mark.
• Sunny south and west walls: direct Florida sun dries them out and slows regrowth, so they can stretch longer between washes.

You'll usually notice one side of the house looking dingy while another still looks clean. That's normal here and it's driven by sun exposure and airflow.

Why Florida is so hard on siding

Two things work against us. First, humidity. Our air holds moisture nearly year-round, and algae like Gloeocapsa thrive on damp, shaded surfaces. Second, water. Lakeland sits among more than 30 lakes — Hollingsworth, Morton, Parker, Mirror, and dozens more — and homes near the water, or backing up to a pond in a deed-restricted community, get even more moisture and shade. That combination means spores are always present and always ready to regrow.

Lovebug season in spring and fall adds another layer, splattering screens, walls, and pool cages with residue that gets sticky and stains if it sits.

Signs it's time, regardless of the calendar

• Green or black streaking on siding, soffits, or the north side of the roof.
• Slick, slippery spots on shaded walkways or the pool deck.
• A general dinginess that a garden hose won't touch.
• HOA or deed-restriction letters — many Polk County communities enforce a clean exterior.

Staying on a regular schedule is cheaper than waiting. Once algae digs into stucco or a shingle roof, it takes stronger treatment and more time to remove. A gentle house washing on a sensible cycle keeps the growth from ever getting a foothold.
