What Causes High Humidity In The Home

Think back to that locker room smell again

What happens in that locker room besides horseplay by kids?

Showering, or so we can only hope!

Well hot showers can create high relative humidity within bathrooms. If the bathroom isn’t ventilated properly this can create a dew point.

Bathrooms can be a prime source of high humidity, but most bathrooms are built to withstand it.

One of the main causes of high humidity is an air conditioning unit that is not properly functioning. If your air conditioning is not dehumidifying properly it could also be a sign that is it undersized or oversized.

How To Get Rid Of Musty Smell In Carpets

If the smell is coming from a carpet, address it immediately. The smell comes from excess moisture and the carpet could be harboring mold and mildew. If the carpet was completely soaked you may have to remove it and replace it.

Take these steps to get rid of musty smells from your carpet.

  • Dry out the entire area. If necessary call a water damage remediation specialist.
  • When the carpet is dry, vacuum it thoroughly.
  • Mix one cup of white vinegar to 2 cups of water and add the mixture to a spray bottle. Spray a light mist over the carpet.
  • Add baking soda to the carpet. It wont harm your carpet or pets!
  • Allow the baking soda and vinegar to sit for a few hours, up to overnight.
  • If the smell persists, repeat with hydrogen peroxide and water. It is one part of hydrogen peroxide to 5 parts of water.
  • An alternative is to use a foam carpet cleaner according to directions.
  • If the odor still persists, it is time to call the mold remediation professionals.

Laundry Drains And Front Load Washers

Many front load washers retain a little water at the base of the unit. Over time, this water grows bacteria, leading to musty smells in your laundry area. We had problems with this in our first front loader. The new unit has a small drain hose, and I clear the stale water out every couple weeks.

An improperly installed drain hose may trap water in the line or allow sewer gases to escape into the home. Make sure drain lines are installed correctly.

How To Prevent Another Infestation In The House

When there is a water intrusion or leak in your home, steps should be taken promptly to prevent any potential mold-related problems that can arise.

The main objective is to fix any moisture problems promptly and then dry materials within 24 hours of them getting wet.

The dry out should be done quickly because when items remain wet for long periods, mold will begin to grow.

Repair all plumbing leaks when they occur.

Frequently inspect windows and AC vents for condensation.

Ensure the air conditioning system is serviced as recommended by the manufacturer. AC systems help to remove excess humidity that can lead to mold growth.

Dont block air vents with clutter, drapes, or furniture. Blocking air vents can cause restricted airflow that will promote mold growth.

Keep the air conditioning drip pans and condensate drain lines clean and free of obstructions.

Maintain humidity levels between 30 to 50 percent.

Clean and dry wet materials within 24 to 48 hours. Mold will begin to grow on items that remain wet for 48 hours or longer.

Vent dryers, range hoods, and bathroom exhaust to the exterior.

Run the bathroom exhaust fans during and after taking a shower .

Avoid placing carpet in moisture-prone areas such as bathrooms, kitchens, and unconditioned basements.

Frequently clean gutters to ensure proper water drainage.

What Else Can Cause A Musty Odor In The Home


As a mold assessor, the number one culprit that I find is causing musty smells in homes during a mold inspection is:

High humidity

Humidity is how the amount of water vapor measured in the air.


Humidity itself can lead to mold growth on both hard surfaces


Mold generally will only be on the surface of hard surfaces and in most cases but may let off what people describe as a mildew smell.

High humidity for an extended period of time could lead to mold growth on porous items such as couches, beds, clothes, etc.

There are many times however by just controlling the humidity within the home that the smell will vanish. The smell of dampness is mostly related to humidity.

    The only way to get rid of the mold smell is to remove the mold. Air fresheners, disinfectant sprays, household cleaning products, candles, incense, and potpourri may temporarily cover up the smell but they wont get rid of it because you are not addressing the source of the smell.

    What Causes Mold Smells

    Many people believe that all mold smells are caused by mold spores, but this is not the case. While some mold smells are caused by mold spores, most mold smells are caused by microbial volatile organic compounds , which are chemicals produced by molds various biological processes. They could be byproducts of the molds digestion, growth or reproduction. And depending on where the mold is in its life cycle, it may produce different odours or seemingly no odours at all.

    People sometimes think that if they cant smell the mold, then it cant harm them. This, however, is completely false. Most health risks of mold are caused by mold spores, while most mold smells are produced by MVOCs. During a mold colonys reproductive stage, it produces fewer MVOCs and more spores, so a mold colony is actually most harmful when it is least smelly.

    While mold odours are a great early warning of mold growth, you should avoid relying solely on your sense of smell to detect potential mold growth in your home. The only way to really be sure that your home is free of mold is to have it inspected by qualified mold professionals. These professionals can use sophisticated detection methods, such as laboratory air testing and surface sampling, which are thousands of times more sensitive than your sense of smell.

    Controlling The Moisture Levels:

    A simple and obvious solution for curbing the mold and mildew growth in the corners is to control the moisture levels of the house. Fungi usually thrive in wet and humid environment, this means bathrooms, kitchen areas and garden shed are more prone to fungal growth. Install exhaust fans and ensure that there are no leakages and damp ceiling in the house. Ensure that there are no damp spots, wet rugs or clothes lying about the house. Keep your house as dry as possible.

    Does A Musty Smell Mean I Have Mold

    Mold is the most common reason for a musty smell in your home. But all homes have some mold and since the mold has a low odor threshold, the musty smell does not mean it is already out of control. What you may be smelling are MVOCs, or mold volatile organic compounds. These are the chemicals that are released at a certain stage in the life of mold that is volatile enough to evaporate but also have an odor that is strong enough to be noticed in a home. This is often not dangerous and can be easily addressed.

    If the odor persists and is stronger you likely have mold and should look for the source of moisture that is causing it. You may also be experiencing an old house smell which is not necessarily a sign of the mold but can be from a number of causes.

    Old house smells can stem from the combination of limited ventilation, high humidity, and darkness. Sunlight and ventilation can often clear this up. The smell may be associated with the carpet, furniture or drapes. Check them out and have them cleaned if so. Do a deep cleaning and deep declutter and that may solve your problem.
