5 Signs Your Humidity Levels Are Too High, And How to Fix It

At Comprehensive Mold Management, we regularly get asked by customers how they can figure out if their humidity levels are too high in their homes.  High moisture levels tend to pose a problem when a warm, heated space, meets a colder area (for example, a poorly ventilated and insulated attic).


Signs Your Humidity Levels Are Too High:

  1.  Window and patio door condensation. Moisture on the interior of your glass doors and windows is one the best ways to know your humidity levels are too high. For more information, check out this article: Window Condensation: Causes and Remedies
  2. Peeling paint, rotting wood, or delaminating plywood. Consistently high moisture levels in your home will eventually lead to peeling paint, rotting wood, and/or delaminating plywood. The built up moisture usually leads to mold growth and the deterioration of paint, wood and plywood.
  3. Mold growth on personal items. When personal items such as furniture, clothing, and blankets start to show signs of mold growth and have a musty smell, it’s usually due to high moisture levels over a long period of time.
  4. Mold spots on the ceiling, skylights, or on corners of the walls. Due to elevated moisture problems, mold spots are often found on the ceiling, skylights, or corners of the walls. This can be caused by water vapor from showers, cooking, or clothes dryers not venting properly. If you live in a newer house, this tends to be more of a problem. Newer houses are built less drafty and heavily insulated, so built up moisture doesn’t have the chance to escape.
  5. Musty smells throughout the home. Musty smells are a sure sign of high moisture, or previous moisture damage in the home.



How to Fix It:

  • Open a window daily to air out your home
  • Keep exhaust fans on for a longer period of time (kitchen, bathroom, laundry room)
  • Open your drapes and blinds daily so air can move more easily against windows
  • Install a dehumidifier with the proper specifications for your home (we recommend the Santa Fe line of dehumidifiers. For more information, check out our Dehumidifier Blog.)

If you spot mold in your home from high moisture levels, do not attempt to clean it yourself. Doing so can cause mold spores to spread throughout the home if done incorrectly. High moisture levels are easy to avoid, whether you have a newer, tightly-built home, or an old, drafty home. As always, if you're not sure about your humidity levels, call an expert to analyze the situation.
