Is There Mold In My Home?

Mold and mildew in homes is more common than you might think. Preventing mold in your home begins with a cleaning regimen and inspection of your living space. But how can you make sure you’re checking all the right spots for mold in your home?  

What Does Mold Need to Grow

Part of knowing where to look for mold lies in understanding what mold needs to successfully grow. According to the CDC, “mold will grow in places with a lot of moisture, such as around leaks in roofs, windows, or pipes, or where there has been flooding.” Mold can attach to a number of materials as well, from cardboard and wood to upholstery and fabrics. As long as there is a damp, warm environment to support development, a mold infestation is likely to occur.  

Where Specifically Can Mold Grow in My Home

To help you cover all your bases, we’ve put together the following list of common areas in which mold could be found. You can use this as a checklist as you inspect your home for mold.

Mold in Grout: Bathroom and Kitchen

As you might imagine, your kitchen and bathroom are the first spots to come to mind when it comes to mold. After all, these are the areas where you use water the most. One place you might not think to look is in the grout between tiles. This includes the grout in your shower as well as surrounding your kitchen sink.

Beyond tile grout, however, there are multiple places you’ll want to check for mold in your kitchen and bathroom. In the bathroom, you should inspect “your shampoo bottles, washcloths and loofahs, shower curtain, in and around the faucet and shower head.” Corners between the walls and floor can be breeding grounds for mold as well.

In the kitchen, you should check beneath the sink, in the pantry, around the microwave, stove, and refrigerator. Don’t leave dishes in the sink and make sure your dishwasher isn’t leaking, even if it’s just a seep. Any moisture can give mold the opportunity to make a home in your household.    

Mold in Bedrooms and Living Rooms

Windows are one spot where moisture can potentially gather and allow mold to grow. Ensure that your windows are properly and tightly sealed to prevent any seepage. If you have any exterior doors in your living room or bedroom, you should also seal those up as tight as possible. Fireplaces and chimneys can also allow moisture to collect, so check those on a regular basis.

Besides windows and doors, textile materials within your home can host mold as well. Mattresses should be covered to prevent moisture from getting into the fibers. Clean your window treatments, couches, and throw pillows often and keep them dry. Air flow is key if your bedroom connects to your bathroom, as the steam created by the shower could get trapped as moisture in the bedroom as well as the bathroom.

Mold in Wood

Any areas in your home that contain exposed wood are susceptible to mold growth. these include framing beams that may be exposed in unfinished areas of your house, such as the basement, attic, or crawl space. We’ll talk more about those spaces in a minute, but be sure that any exposed wood or drywall is careful inspected on a regular basis for moisture and/or mold growth.

Mold in Attic and Underside of Roof  

Moisture and humidity typically gather in your attic or the underside of your roof if there is a leak. Inspections of your roof should be done on a regular basis, and any repairs that need completed should be done well in advance of any inclement weather. It’s a good idea to look both inside the house, in the attic, as well as the exterior of the house on the roof. Attic ventilation will prevent mold growth as well.

Mold in Vents

A house typically has a number of vents for various purposes. Your kitchen, bathroom, and laundry room will have vents for the stove, shower, and dryer. Soffit vents, “the vents near the bottom of the roof that provide ventilation to the attic,” can also host mold growth. Water heaters and furnaces most often have vents as well, so check these for mold on a regular basis. Gutters can also be a perfect place for mold to grow.

Mold in Basement, Garage, and/or Crawl Space

Since most basements can be unfinished, they may not be as protected from mold growth as the rest of your house. Garages and crawl spaces are the same way. To protect from mold growth in these areas, inspect them often. You can also use a dehumidifier to keep humidity low, ventilation to keep air temperatures down, and you should also declutter your space to prevent any mold from growing without notice.

How to Prevent Mold in Homes

Maintaining a clean household is one of the best ways you can keep mold at bay.

Below is a list of more measures you can take to stop mold growing in your home:

  • Humidity levels should be low. Air conditioning units and dehumidifiers can help control humidity levels, as they should be “between 30% and 50%.
  • Ventilation is crucial, especially in bathrooms, kitchens, and laundry rooms. Ensure these areas in your home are well-ventilated so that air can flow in and out to remove heat and humidity.
  • Diagnose and repair any leaks immediately. This is especially crucial for those living in older homes. Pipes can burst, roof leaks can occur, and excessive rainfall could uncover seeping holes in your windows and doorways.
  • Dry out any moisture thoroughly as soon as possible. Remove as much water as you can from the area. Dispose of any items that came into contact with the moisture that cannot be cleaned properly.

So what do you do if you encounter mold in your home?
