Why East Texas Homes Are Vulnerable

East Texas has the kind of climate that can encourage mold and mildew on painted surfaces. Warm temperatures, high humidity, shaded siding, tree coverage, and moisture around landscaping can all contribute to recurring exterior staining.

  • High humidity
  • Shaded walls
  • Tree-covered lots
  • Pollen and organic buildup
  • Sprinklers hitting siding
  • Clogged or overflowing gutters
  • Poor airflow around exterior walls

Painting over mold or mildew is not a long-term fix. The surface should be cleaned and prepared before repainting.
