House Smells Stale After Vacation; Is It Mold or Mildew?

Did you just come back from a vacation and notice an odd smell that seems stale in your house? Even while it might be unsettling, you could be wondering if it’s mildew, mold, or something else.

To properly treat the issue, it’s important to identify the source of the stench. We’ll look at several possible reasons for that musty smell in this blog post and offer advice on how to spot and get rid of it.

What Does ‘Stale Smell’ Mean?

Stale smells are often caused by not enough air flow, too much moisture, and too much organic matter or waste.

These things make it easy for mold and mildew to grow, but they’re not the only ones to blame.

A musty smell can also be caused by things like weak air flow, dust, and surfaces that haven’t been cleaned. To deal with the smell properly, you need to first find out where it’s coming from.

1. Mold?

Mold is a common problem in homes that can affect your health and damage your belongings if you don’t get rid of it right away. Mold grows best where it’s damp and dark, and it can quickly cover surfaces like floors, and walls.

  • Visual Signs: Mold often shows up on surfaces as black, green, or white spots. The feel of it might be fuzzy or slimy.
  • Odor: Mold has a strong, musty smell that people often describe as earthy or rotten. Mold is probably to blame if the musty smell is very strong and doesn’t go away on its own.

2. Mildew?

One type of mold that usually develops on damp surfaces is called mildew. Though less pervasive than mold, it may nevertheless be the cause of your issue.

  • Visible Signs: A powdery, white or gray development known as mildew can be seen on surfaces including shower walls, windowsills, and textiles.
  • Odor: Mildew generally smells less strongly than mold, but it still has a musty scent. Mildew might be the source of the faint, localized stale scent.

3. Other Common Household Issues

If mold or mildew isn’t the source of the stale smell, take into account these additional possibilities:

  1. Poor Ventilation: Odorous and stale air can result from inadequate ventilation. This is typical of houses that have been unoccupied.
  2. Household Dust: Odors can be present in accumulated dust, particularly if it contains organic materials such as food particles or pet dander.
  3. Unclean HVAC Systems: When dust and mold build up in HVAC systems, the system emits a musty odor that permeates the entire house.

"Out of all of the options in the area, I’m so glad I went with Mold Solutions. They were the only ones that can thoroughly handle my entire problem, including the air conditioning ducts where other companies were telling me I needed 3 to 4 different service people with different bills all coming to my house at different times costing me tons of money. They got everything done in one day. I felt the difference in my health immediately after they finished." — 5-Star Google Review

Mold solutions just remediated mold in my air handler and ductwork throughout my home. They were very thorough. I was impressed with their knowledge of mycotoxins from mold and the seriousness of mold. All of the staff that I interacted with was patient, friendly, helpful and efficient. They kept me informed and I was super happy that the entire home was dry fogged with pet friendly ingredients. My two cats and I had to go out on the patio for 3 hours as the dry fog did it's thing. They kept me informed and let me know when it was perfectly safe to go back inside. Trustworthy, efficient and nice.
