Staining and Growth

Typical Places to Look:

  • Siding
  • Below windows, roofs, decks, etc.
  • Bases of walls
  • Bricks (efflorescence)
  • Concrete (walls, ceiling, subgrade)

Details:

  • Excess moisture behind cladding will leak out around sources.
  • The base of a wall touching landscaping, concrete, or ground will wick up moisture.
  • Excess moisture traveling through brick will leave behind white salts.
  • Excess moisture traveling through concrete will cause staining and spalling.
  • Excess moisture will cause blistering.
