Patio Cleaning in Key Biscayne - A Seasonal Guide
Key Biscayne's patios go through distinct cycles over the year, and timing your patio cleaning around them gets better, longer-lasting results than cleaning on a random schedule.

Rainy Season (Roughly May Through October)
Frequent rain combined with heat and humidity creates ideal conditions for algae and mildew growth on concrete and cement patios, particularly in shaded areas that don't fully dry between rain events.

02 / Seasonal guide
Dry Season (Roughly November Through April)
Lower rainfall means slower algae regrowth, making dry season a practical window for a deeper patio cleaning, since results tend to hold longer before the next rainy season resets the cycle.

Year-Round Salt Air Exposure
Unlike seasonal algae growth, salt air exposure in Key Biscayne is constant, and it steadily wears down sealant on concrete patios regardless of season.

Best Time to Schedule Patio Cleaning
For most Key Biscayne properties, scheduling a thorough patio cleaning near the start of dry season sets up cleaner, longer-lasting results. A second cleaning partway through the rainy season helps control algae buildup before it sets in deeply.
