If your screen enclosure is turning green, you’re not alone. Algae growth is one of the most common problems affecting pool cages, screened patios, and lanais throughout St. Johns, Florida.
Many homeowners invest thousands of dollars in a beautiful screen enclosure only to watch it slowly disappear behind a layer of green algae, mold, mildew, and dirt. The good news is that algae can be safely removed and your enclosure can look almost new again with the proper cleaning methods.
Why Does Algae Grow on Screen Enclosures?
Florida’s warm temperatures, high humidity, and frequent rainfall create the perfect environment for algae growth. Screen enclosures provide plenty of shaded areas where moisture can remain trapped for extended periods. Once algae spores land on the screens and aluminum framework, they begin feeding on dirt, pollen, and organic debris that naturally accumulate over time.
Homes located near wooded lots, retention ponds, and heavily landscaped properties often experience algae growth much faster than neighboring homes.
Signs Your Screen Enclosure Needs Cleaning
Many homeowners become accustomed to seeing algae and don’t realize how dirty their enclosure has become until it’s professionally cleaned.
Common signs include:
- Green staining on aluminum framework
- Black mold spots around joints and corners
- Dark streaks running down support beams
- Discolored screen mesh
- Spider webs and insect buildup
- A neglected appearance
A clean enclosure should enhance your backyard view.
Why Pressure Washing Isn’t Always the Best Solution
One of the biggest mistakes homeowners make is blasting their screen enclosure with high pressure water.
While pressure washing can remove surface dirt, too much pressure can:
- Damage screen mesh
- Tear older screens
- Bend aluminum framing
- Force water into unwanted areas
- Shorten the lifespan of screen components
- blast out the screen splines which leave your screens flapping in the wind.
Professional cleaning typically combines low-pressure washing with specialized cleaning solutions that kill algae at the source while protecting the enclosure.
The Best Way to Clean Algae from a Pool Cage
A professional screen enclosure cleaning process generally includes:
1. Applying a Cleaning Solution
The enclosure is treated with a cleaning solution designed to break down algae, mold, mildew, and organic growth.
2. Allowing Dwell Time
The solution is allowed to remain on the surface long enough to kill the growth and loosen stubborn staining.
3. Low-Pressure Rinsing
The enclosure is thoroughly rinsed using safe water pressure that cleans without damaging screens or aluminum.
4. Detailing Problem Areas
Heavy algae buildup, corners, support beams, and screen doors may require additional attention to achieve the best results.
How Often Should a Screen Enclosure Be Cleaned?
In St. Johns County, most screen enclosures benefit from professional cleaning every 12 to 24 months.
However, certain factors may require more frequent service:
- Large oak trees overhead
- Pine trees dropping needles and pollen
- Homes near water features
- Heavy shade around the enclosure
- High humidity areas with limited airflow
Regular maintenance prevents algae from becoming deeply embedded and keeps cleaning costs lower over time.
Can Algae Damage a Screen Enclosure?
Algae itself may seem harmless, but allowing it to remain for years can create additional issues.
Organic growth traps moisture against painted aluminum surfaces, contributes to staining, and accelerates the dirty appearance of the entire backyard area. The longer algae remains, the more difficult it can become to restore the enclosure’s original appearance.
Think of algae like weeds in a flower bed. It starts small, but eventually takes over if ignored.
The Hidden Benefit of a Clean Pool Cage
Most homeowners expect a cleaner appearance after service.
What they don’t expect is how much brighter everything looks.
After cleaning a year of algae buildup, most customers can notice how much sunlight returns to their pool area. The enclosure appears lighter, cleaner, and more inviting, making the entire backyard feel larger and better maintained.
