First Aid For Moldy Crawl Spaces

Got Mold in Your Crawl Space? What To Do First
  • Watch out: Do not enter or work in a moldy area without wearing proper respiratory and other personal protection.

I Recently Renovated A Bathroom There Is New Sheetrock Plaster And Paint In This One Area The Wall Started Bubbling When We Chipped Away At The Loose Paint There Was White Stuff That Grows Back When Removed This Wall Is Next To The Tub/shower Is This Mold What Should I Do

This doesnt look like mold growth. It appears to be deformation of the mud/plaster due to excess water. I recommend investigating further with a moisture meter. Your goal is to identify whether the water is 1.) Entering the wall from the backside 2.) Occurring due to splashing water during shower usage, or 3.) Excessively wet mud/plaster was used during the install and is deteriorating as it dries out.

If its the latter option, the moisture meter should show lower moisture content levels with each passing day.

What Is Mold Anyway

Molds are fungi. Fungi are neither animals nor plants. They inhabit a kingdom all their own. Fungi are spore producing organisms that feed on organic matter and include: yeasts, mildews, rusts, smuts, molds, and mushrooms. Fungi grow using filaments or hyphae that make up their bodies . They digest organic matter externally before absorbing the nutrients.

Assuming the shoes are stored in a closet, it is likely mold growth. White mold growth on shoes is nearly always due to high humidity. Closets in an older home often suffer from elevated humidity due to the lack of air flow and heat, combined with poorly insulated exterior walls. Keeping the closet door slightly open is often enough to solve the issue. This will allow heat to enter the area and moisture to escape. You can also assist the dry out by installing a moisture absorbing material such as Damp Rid.

Unfortunately, this is fairly common in new construction. There are a couple of possible causes. The subfloor and joists often become saturated by rain before the roof is installed. Over the subsequent weeks, mold growth forms before the building materials can dry out. Another common cause is exposed soil in the crawl space. Most builders wait until the very end to install the vapor barrier. If the soil beneath the home is damp, this can create high humidity conditions in the crawl space. Over time this will cause mold growth on the joists.

Why Should You Be Concerned About Crawlspace Mold

Mold can result in a negative impact on your health

One of the easiest places for mold to grow is in your crawl space since it doesnt necessarily require sunlight to grow. In fact, the major factor that mold needs for growth is moisture.

Mold can result in a negative impact on your health and continued exposure to crawl space mold can lead to a range of health issues. These problems may include eye irritation, coughing, wheezing, nasal stuffiness, throat irritation, eye irritation or even skin irritation.

Furthermore, some more serious ailments like obstructive lung disease have been linked to prolonged exposure to mold and damp places in general. And what makes this type of mold a lot more dangerous is the fact that you dont have to go into your basement to be exposed.

Thanks to the Stack effect, the air from your crawl space finds its way into your house and circulates. Since heat rises, warmer air rises which then brings along with it various particles. Some of these particles are crawl space mold.

Institute of Medicine publications in 2007, 2010, and 2011 reiterated evidence that linked association with damp spaces and indoor mold to respiratory illnesses. Therefore, spending time in a place with mold present such as your crawl space is a potential cause of ill health.

Wood Rot On Bottom Of Joists

Amazingly, this was not due to direct saturation, but rather extreme humidity in the crawl space. This kind of damage is extremely rare.

Water Damage on Subfloor in Crawlspace

  • Inspection of crawlspace revealed moderate mold growth throughout significant areas of subfloor and floor joists.
  • Significant areas of rot were noted in framing along exterior wall, the inspector was able to pass a 3.5 knife blade completely into the rim-joist along the back foundation wall.

How To Identify Mold Vs Mildew In Your Home

  • Email

Mold and mildew are often spoken of together, almost as if they were the same substance. We fear mold and mildew growing below our homes in crawl spaces, under house siding, around the bathroom wall surround, and behind the sink. Excessive, pervasive mold and mildew can hamper a house sale or cause homeowners to move their bedroom elsewhere. Neither mold nor mildew is welcomed in the home, in any form.

Though related, mold and mildew are separate microorganisms that grow differently and must be treated differently. Safely eradicating mold and mildew is crucial to keeping you safe and your home in good shape.

Is Crawl Space Mold Dangerous? | How Bad is the Mold in Crawl Space?

I wouldnt worry about identifying the specific type of mold growth. The remediation and prevention is the same, regardless of species. Your need to lower the humidity in the area these tapes are stored. Aim for a relative humidity of < 50% with< 60% as your maximum. If you live in a climate with cool winters, this can be achieved by increasing the ventilation to the storage area and increasing the heat/temperature. The higher the temp, the lower the RH. Purchase a relative humidity gauge to monitor your efforts. If you live in a very humid location such as Florida, youll need active dehumidification.

Humidity problems are typically worse in closets or cabinets, due to the poor air flow. Try moving the tapes to an area that is more actively conditioned/heated.

Preventing Mold Caused By Basement Condensation Issues

There are two methods to prevent mold growth in your basement caused by moisture and condensation.

Try anti-mildew paint in your basement

Re-paint your concrete foundation where youre experiencing surface mold growth with an antifungal paint such as KILZ . These types of paints advertise that they prevent mold growth on the surface of the paint. In my experience, they dont always work, though.

Insulate your foundation to prevent condensation

The second thing you can do would be to insulate your concrete foundation walls. There are many different options: Styrofoam, spray-foam, or finishing the basement. Insulated walls would prevent that difference in temperature that causes condensation and mold growth.

Efflorescence Or Mold Water Damage In Basements Or Crawl Spaces

I heard an unfortunate story recently about a pair of new homeowners who hadnt properly inspected their basement before they moved in. While the home was mostly in good shape, with a sound roof, a recently remodeled kitchen, and new floors throughout, it only took three months of living there to realize they may have overlooked some troubling signs in their walk-in basement and in the crawl space under the breezeway.

They noticed a white material on the basement walls that was damp to the touch, and upon further inspection, they found a similar substance in the crawl space. Although the crawl space would not be regularly used , it was still an issue they needed to address before it became a health risk.

Besides identifying the source of the moisture, it was important for the homeowners to determine whether the white substance in question was a case of efflorescence or a more harmful mold, both of which result from moisture intrusion. If youve never heard the term before, efflorescence is a salt deposit that can appear on the exterior or interior of a structure, and its easily mistaken for mold or mildew. For homeowners trying to troubleshoot moisture problems in their basement, understanding the difference is important to be able to treat and prevent it.

White Mold In Your Car

White Mold in Crawl Space or Something Else? Crawl Space Mold on Block : White Mold on Block Wall

Even though your car isnt technically your home, it is still one of the more common places we have found white mold. The truth is that moisture can easily make its way into your car, whether through the air conditioner, a poorly sealed window, door or sunroof, a spill, or simply an open window. Once mold has started growing inside your car, it can quickly spread onto upholstery, carpeting, and seatsultimately destroying your vehicle. And if mold has gotten inside your cars air conditioner, it will circulate through the air and expose you to potentially toxic mold spores. The best indication that your car has mold is white spots or an earthy odour.

Tackling mold in the crawl space and along the floor joists is a physical job. It takes a lot of scrubbing and the ability to squeeze into tight spaces. Because of these working conditions, you need the property safety gear and cleaning agents to get the job done quickly and without jeopardizing your health. Have the following personal protective equipment:

You also need to gather cleaning supplies:

  • Plastic sheeting
  • Sponges/old cloths
  • Brush, putty knife, or small shovel

Before proceeding, you need to decide on what you are using to clean up the mold you find in the crawl space. Some individuals choose to make their own household solution cleaners. You can use ammonia, bleach, tea tree oil, or vinegar to remove the mold. You can also purchase a commercial-grade cleaner, such as a mold remediation company would use.

Whatever you decide to use, you need to be thorough and systematic in your approach to getting rid of the fungus. Here how to get started with mold removal:

  • Put on your protective clothing, gloves, or goggles before mixing up your cleaning solutions.
  • Using a small brush or the flat part of a putty knife, scrape off or remove any large growths of mold that you see. You can scrape these into a trash bag or let them fall to the floor. You will be disinfecting the dirt once you are finished with the floor joists and other spaces.
