Preparation

Evaluate What Needs to be Tested

Where to Test

Test areas that are known or suspected of having water leaks (e.g. – roof leaks, flooding, pipe leaks, etc.) If specific areas cause sneezing and coughing, they should be included. Include more than one mold plate in large areas or rooms.

We recommend testing each of the following areas:

Bathroom

Basement

Master Bedroom

Den/Great Room

Car

Kitchen

Child's Bedroom

Office (Home & Work)

Where it Grows

Roof and Attic
  • Flashing, gutter, or canale leaks
  • Bad seals around penetrations, like chimneys
Rooms
  • Closets with high humidity
  • Window and roof leaks
  • Flooding
Laundry Room
  • Washing machine mold
  • High humidity
  • Plumbing leaks
Kitchen
  • Plumbing leaks around sink and drain pipes
  • High humidity in cabinets
  • Refrigerator ice maker leaks
  • Decaying food and trash
Air Conditioning Systems
  • HVAC systems causing condensation
  • Mold inside HVAC systems (on coils and in ducting)
  • Inadequate ventilation
Bathroom
  • Plumbing leaks around sink, bathtub, shower, and toilet
  • Elevated humidity
  • Caulking that is lifted or broken
Windows
  • Moisture from bad seals
Basement and Crawlspace
  • Moisture transfer through cement floors and walls
  • Water settling against foundation
  • Dirt crawlspaces without proper ventilation
  • Standing water in sump pumps

How it Grows

Mold can be found anywhere water is allowed to remain for 48 hours or more. Humidity above 60% can also lead to mold growth. Mold needs a food source, water source, and warm temperatures to grow.

Food Source

Such as wood supports, drywall backing, wallpaper, carpet, cabinetry, books, cardboard boxes.

Water Source

Such as a busted pipe, roof leak, poorly graded building site, flooding, high humidity, or other moisture causing event or conditions.

Warm Temperatures

40º – 120º F
