mold mildew in home on walls
October 22, 2020

Have you been noticing an off smell in your home lately? Many homeowners in Arlington, Northern Virginia, and the Metro DC area have been spending more time than usual inside their houses this year, which may make them more aware of any unpleasant, funky indoor odors.

If you’re wondering what causes musty smells in a home, or are trying to get rid of the musty smell in your home’s AC vents, it’s likely you’re experiencing one of the signs of mold in your house. Here’s what causes moisture and mold in a home and how you can do to remedy the issue.

Why Does Mold Grow in a House?

Mold needs a few things to grow: moisture, warm temperatures, and something to eat. Two of those three components can be found in almost any house: the interior of your home is likely warm and comfortable, and mold can feed on a number of common building materials, including sheetrock and construction wood. This means that the real culprit for mold is moisture.

Indoor moisture is likely the result of:

Inadequate ventilation—Are you turning on the bathroom fan when you take a shower or the vent above the stove when you cook food? These everyday activities can make your indoor air humid and wet, creating the perfect conditions for mold growth. Have you noticed sweating glass in your bathroom or kitchen? Those are perfect signs that the air in your home is too humid, and mold growth on your walls can follow.

Poor insulation levels and air leaks in your home—Many homes rely on air sealing and insulation to stop condensation in their houses, as well as to prevent water or outdoor moisture or humidity from entering. Oftentimes the problem is hidden away behind walls, or in your basement or crawlspace, but if the mold growth becomes widespread, you can see signs of mold under floors, in your crawlspace or basement, and more.

How Can You Prevent Indoor Mold Growth

Mold not only creates unpleasant smells, but depending on how bad mold is in your home, it can also create indoor air quality problems and health hazards for your family. Signs of mold sickness of mold allergies include:

  • Sneezing, runny nose, and red eyes

  • Asthma attacks

  • Increased allergic reactions

If there is a small amount of visible mold on your walls, it’s easy enough to treat it with a cleaning solution. But you won’t be fixing the underlying cause that led to that mold growth in the first place, and it can be difficult for the average homeowner to really check or test for mold in their home.
