Why does stucco turn green, gray and black in Coral Springs?
Warm temperatures, high humidity and regular afternoon rain give mildew and algae ideal conditions for most of the year. Walls that stay shaded, such as the north side of a house or areas behind hedges, grow green or black film first. Sprinklers that spray the wall add moisture and often leave rust-colored streaks as well.
Stucco holds that moisture in its tiny pits, so growth takes hold and keeps coming back. Light paint colors show the dirt quickly, and a wall that looks tired can make the whole house seem neglected.
In a community with a homeowners association, that look can lead to a notice. Washing is often the simplest first step before anyone talks about repainting.
