How to Remove and Prevent Algae on Your Pool Cage After Summer Rains in Riverview, FL

July 10, 2025

After a typical Riverview summer, many of us step outside to enjoy our backyard pool oasis—only to find our pool cage covered in blotchy green or black algae. With the mix of daily rain and heat, it’s a perfect storm for algae to take over. The good news? With a little knowledge and a regular cleaning plan, you can keep your pool enclosure fresh, healthy, and inviting all year long.

Why Algae Loves Riverview Pool Cages

Algae thrives where there’s moisture and a little shade. Pool cages sit directly above a source of humidity, and Florida’s summer rain keeps everything damp. Large trees, dusty pollen, and wind-blown debris all add to the perfect growth environment. The risk isn’t just cosmetic: left unchecked, algae builds up, attracting insects and potentially damaging your screen’s paint.

Our Proven Approach to Removing Algae

  • Gentle chemical pre-treatment – At Riverview Pressure Cleaning, we begin with a mild cleaning solution specifically chosen for your pool cage materials. This helps break down dirt, dust, and algae so the next steps are more effective—and safer for your enclosure and landscaping.
  • Low-pressure rinsing – High pressure does more harm than good on fragile screens! We wash using lower, controlled pressure to avoid damage. This ensures a thorough clean without risking paint or screen tears.
  • Detail checks – We don’t just spray and dash. We go corner-to-corner, making sure joints, frames, and hard-to-reach areas get the attention they deserve—because that’s where algae likes to hide.
  • 30-day satisfaction promise – If you spot any missed spots or issues within 30 days of service, let us know. We stand by our work and will come back to make it right.

DIY or Professional? Think Safety and Lasting Results

Many homeowners wonder: is it worth doing this myself? For light touch-ups, a gentle soap, vinegar, and a soft brush can handle isolated spots. But remember—from our recent blog about DIY vs. professional cleaning, most DIY jobs lack the power (or proper chemistry) for a lasting deep clean. Too much pressure can also crack frames or wear paint. If you have persistent stains, recurring algae, or just want to avoid risking a fall from a ladder, it may be time to call in a pro.

Long-Term Algae Prevention Tips from Twelve Years in Riverview

  • Minimize standing water: Sweep leaves and debris away from the base of the cage and deck.
  • Trim back trees and shrubs: Sunlight helps dry the cage quickly after storms, reducing algae growth.
  • Keep up with regular rinsing: Every few weeks, especially in rainy season, rinse your enclosure with a garden hose or apply a light vinegar solution to slow new algae growth.
  • Don’t skip professional maintenance: Schedule deep cleaning at least once or twice a year—especially after a long, wet summer. Protect your investment and preserve your home’s beauty (many HOAs require it too!).

What to Watch Out For

  • Black algae: This stubborn variety often returns fast after a Florida summer. If you keep seeing dark spots every month, it could be time to upgrade your cleaning technique or call in a professional for a deeper treatment.
  • Paint damage from high pressure: If you’ve noticed chalky or flaking paint on your frame or screen, stop and reassess—gentle cleaning is key.

Final Thoughts

Florida’s weather isn’t gentle on pool cages, but keeping algae under control doesn’t have to be a chore. Regular care, a watchful eye after a big rain, and thoughtful annual professional cleaning can keep your pool area as inviting as the day it was built. If you’re ever in doubt or simply want the job done right, reach out to us at Riverview Pressure Cleaning. We’re your neighbors and understand exactly what your home needs to shine, safely.
