Green on your siding? Algae, mildew, and pollen on the Grand Strand
That green film on the shady side of the house is living growth. Here's why it keeps coming back and what actually stops it.
Why we wrote this: Mold, algae, and pollen removal are top mentions, along with homes that look brand new afterward.
Humidity, shade, and heavy spring pollen make coastal South Carolina perfect for algae and mildew. It shows up first on the north side of the house, under eaves, on fences, and on pool screens.
Why rinsing doesn't last
Spraying it off removes the top layer but leaves the roots, so it grows back in weeks. A soft wash solution kills it, which is why results last far longer.
Pollen season
The yellow coat that shows up every spring sticks to screens, windows, and cars. A wash after pollen season wraps up keeps it from mixing with moisture and feeding new growth.
