DIY Tip: How to Prevent Musty Smell/Odor in Your Basement

With mold and mildew forming the majority of a basement’s musty smell, other causes can round off the smell and give it that singular odor:

  • Damp Materials: Drywall, fiberglass and rockwool insulation, and especially wood in all forms can add to a basement’s musty smell when wet and not allowed to properly dry out.
  • Sewage: Sewage lines typically run through the basement before continuing outside. Sewage problems can range from improperly fitted pipes that emit odors to liquid sewage spills from pipes.
  • Animal Waste: Rodent droppings look like dark grains of rice and can contribute to the sour smell in a basement. Not only that, rodent feces can spread diseases such as hantavirus and salmonella.
  • Iron Ochre or Iron Bacteria: Iron ochre looks like slimy mud. In fact, this vibrant red-brown wet material is a bacteria that feeds off of iron and adds a rotten-egg smell to the basement.

Types Of Basement Mold

Various types of mold will infest your basement. While they are all hideous, not all of them are toxic to humans.

Molds can be divided into two categories:

  • Allergenic
  • Mycotoxin/black

Allergenic molds usually pose no health risk unless you are extremely sensitive to molds or asthmatic. Black molds, on the other hand, produce a toxic chemical called mycotoxins and are particularly harmful to humans and pets.

Here are the common types of molds that can infest your basement.

Aspergillus

Aspergillus is one of the most common household mold species. There are different types of Aspergillus, and most of them thrive well indoors. Some of the Aspergillus molds are allergenic, but some are mycotoxin and should be removed by a specialist, especially if it is something like black mold.

This fungus is dark green and found on damp walls, ceilings, and even furniture. It flourishes in humid environments, but can also grow in areas that are dry with high levels of humidity or condensation.

Baking soda is helpful in many other ways due to its absorbent properties. If you cant remove carpeting without ripping and ruining it, baking soda in the carpets absorbs unwanted moisture and makes them a less likely area to harbor spores.

Inspect Your Basement For Leaks

Finding the mold or mildew source is crucial if you want to remove that unpleasant smell from your basement.

You Have Mildew Or Worse Black Mold

How To Get Rid Of That Musty Smell In Your Basement

Ok, so lets start with clarifying the difference between mildew and mold.

Mildew is actually a form of mold. Without getting too deep into the differences, at a high-level, mold is generally more dangerous to your health and mildew is more of a cosmetic problem.

But both can cause your basement to smell musty and need to be removed.

And in this article when we refer to mold or mildew, it could be either.

Now lets get back to how to remove them.

Do you see black, white or green patches growing on the floor, walls or ceiling?

Well, its established that you are dealing with mold.

But what we do not know is how severe the infestation is.

Whats visible might be the tip of the iceberg. Mold likes to hide in places that are oblivious to sight, like tiny crevices in the wall or in your carpet.

If you are lucky, its just the circulation of warm air in the house thats causing condensation on the walls in the basement resulting in an increase in moisture.

But if thats not the cause, then you have to play detective and rule out all possible causes one at a time.

A crack in the foundation wall, a window seal thats broken, a leaky pipe or even a laundry vent thats fractured. ;The source of the moisture can be anywhere.

Most types of household mold can be eliminated by yourself with some patience, some elbow grease and some basic tools that can be found around home.

But first, we need to be aware of what we are up against.

Lets begin.

Opening the basement door and smelling a musty odor is not pleasant. Many homeowners choose to turn the basement into usable living space. A basement with a musty odor is not a place where a homeowner wants to entertain, relax or make a playroom for the children. A musty smell in a basement is a telltale sign of dampness. Dampness leads to mold and mildew growth, making the environment unhealthy. Mold and mildew harms a home and threatens the structure. Ridding the musty odor is necessary to improve the quality of a home.

  • Look for signs of mold and mildew on the walls, in closets and around windows and doors. Clean the mold with equal amounts of chlorine bleach and water, or a commercially available mold killer. Spray the mold killer on the moldy or mildewed areas and scrub them away with a scrub brush.

  • Examine the basement walls for cracks and holes. Apply hydraulic cement to the cracks and holes with a putty knife to seal them from water entry. If the entire wall feels damp, paint a coating of waterproofing material on the walls.

  • Grade the soil away from the foundation of the house, forcing water to flow from the house rather than toward it.

    Your bathrooms Moist and warm, bathrooms are like heaven to mold spores. You will want to check the most obvious places like the tiles in the shower but do not forget to check under the sink, around the toilet, and in the walls. Water leaks may not always be evident right away, but if you do a thorough inspection of your bathrooms, you should be able to tell if there is a moisture problem causing mold growth.

    The kitchen There are a lot of places in the kitchen for mold to hide out, so you will want to check thoroughly. Look inside of, underneath, and around your refrigerator, underneath your sink, and inside your microwave and stove. Oh, and do not forget to check your trash can that is another dark place mold cannot resist.

    In the bedrooms True, your bedroom may not seem like a great place for mold to grow but its very possible. To keep your room smelling fresh, you will want to check for mold on your mattress, your bedroom windows and windowsills, and in any potted plants you have.

Once you have identified the source of the musty smell in your home, decide whether it requires maintenance that you can do yourself or if it makes more sense to hire a contractor to do the work for you. If you are renting, keep in mind that most leases require your landlord to pay for the repairs.

    Mold In The Basement: Identifying And Treating It

    Homes that have basements often have mold. Due to basements’ proximity to groundwater, water can wick up through concrete floors and continue wicking up through floor sleepers and wall studs. Homes without a robust water diversion system may accumulate water in the soil that can crack the foundation, which results in water leakage.

    Identifying and treating basement mold is a multi-stage process. You must find the mold, then test it to make sure of what you’re dealing with. You’ll remove structural elements to permit access to the mold, as needed, and go through the process of killing the mold. Then you’ll mechanically remove or encapsulate the dead mold spores, depending upon which is best for your situation. Finally, you’ll turn your attention to fixing the problem that allowed the mold to grow in the first place.
