On house siding (vinyl, hardie-board, composite board, & solid painted wood), we warrant and guarantee that fungus, mold, mildew, and algae will not return up to 6 months after the date of service. If mold or mildew return, we will clean it at no additional charge. This applies to the treated areas only. For example, if you elected to have only 2 sides of the house cleaned (typically north/shady sides), this would not apply to the south/sunny sides.
Warranty does not extend to pollen, dirt, clay or paint splatter, nor other non-organic staining*. Warranty does not apply to Stucco or Synthetic Stucco/EIFS siding, nor stained wood.
