When Should You Clean Your Screen Enclosure? (Signs to Watch For)

Florida screen enclosures should be cleaned every 6-12 months, but many homeowners wait too long and end up with mildew that has already stained the screen material. Here are the six clearest signs it’s time to book service - and why waiting makes it harder to clean.

1. You See Green or Gray Tint on the Screens

Mildew and algae start as a light tint that's easy to miss - especially at a distance. Look at your screens with the sun behind them. If they look green, gray, or hazy, mildew has already taken hold.

2. The Aluminum Frame Is Streaked or Chalky

Florida humidity oxidizes aluminum framing. If your frame looks chalky white or streaked black, it's not just cosmetic - the finish is breaking down. Regular cleaning slows the oxidation dramatically.

3. There's Visible Buildup at Kick Plates

Kick plates - the horizontal aluminum panels along the bottom of the enclosure - collect the worst of the buildup because they're closest to grass, dirt, and irrigation spray. Green film here is a clear signal.

4. Pollen Season Just Ended

Central Florida pollen peaks in February through April. According to University of Florida IFAS Extension, pollen counts in Pasco and Hillsborough counties routinely rank among the highest in the state during peak weeks. Screens trap it, and it becomes a food source for mildew.

5. Water Beads Are Turning to Streaks

When your screens or aluminum frame no longer bead water, dirt and mildew have coated the surfaces. Rain now spreads streaks around instead of running clean.

6. You're Ready to Sell (or Just Had a Hurricane)

Two situations where cleaning becomes urgent:

• Before listing your home - a cloudy enclosure kills first impressions
• After hurricane season - wind-driven debris and salt spray leave residue that must be removed before it stains permanently

Why Waiting Makes It Worse

Mildew is easy to remove when it's on the surface. Once it works into the screen material, it stains permanently - and no cleaning removes it. The point of scheduled cleaning is to remove mildew before it stains.

The same applies to aluminum framing: light oxidation cleans off. Advanced oxidation requires refinishing.

Can You Pressure Wash a Screen Enclosure?

Absolutely not with high pressure. Screens stretch and tear at pressures above what a garden hose delivers. Professional patio and screen enclosure cleaning uses:

• Very low pressure (below garden hose PSI)
• Biodegradable detergents to break down mildew chemically
• Detail work on frames and kick plates
• Concrete or paver surface cleaning included

What About the Pool Deck Underneath?

Most pool enclosure services include the concrete or paver surface as part of the same visit. If you have pavers, ask about sealing them at the same time - the paver surface is already cleaned and prepped.

How Much Does Screen Enclosure Cleaning Cost?

Most Wesley Chapel pool enclosures fall in the $175-$375 range depending on size. Bundling with a house wash or roof wash typically saves 10-15%.
