Preventing Mold In Crawl Spaces

Whether you have dealt with mold in your crawl space before or not, implementing measures to prevent mold growth is essential. There are several things you can do to reduce moisture buildup under your home, which is the primary cause of mold.

First, you should seal or waterproof any cracks in your foundation. Sealing gaps will prevent water from seeping in after rainfall or from other runoff.

Another great way to reduce the amount of water that gets into your crawl space is to implement adequate drainage outside your home.

A sound drainage system includes gutters, downspouts, and gutter extensions to move problematic rainwater away from your foundation wall, as well as a French drain system that can move runoff to a safe area of your property.

Next, you should install a vapor barrier in your crawl space if you dont already have one. This kind of crawl space encapsulation gets installed on the walls and floor of your crawl space and helps keep moisture out.

If your crawl space is vented, you may want to consider having it sealed to prevent moisture from the outside from getting in.

The sealing process is best left to professionals, as crawl space vents and any openings need to be fully adequately sealed to be effective.

Lastly, a sump pump and dehumidifier can work to remove standing water and water vapor from your crawl space, respectively. These should be your last line of defense but can keep your crawl space air well-conditioned and dry to prevent mold from forming.

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.

Reader Question About Mold In Dirt Crawl Space

Hi I have attached a few pics of the mold growth on my dirt crawl space each pic is isolated and no further spread is seen anywhere else.

I was actually shocked to see this strange looking growth. I do keep the crawl vents open but there is no forced air movement at all. Please assist as to how to safely remove.

The house sustained a fire in may of 2014 and the ac system has been off since. There are fans running in house though.

The only power to crawl space is to the sump pumps that discharge any water to the outside via pipes which none of the pics of the mold spores / mushrooms are even close to the sump liners of perimeter pipe in perimeter ditch.

There is no black plastic liner on dirt floor and no floor joist insulation, I removed all several years back when I dug my perimeter ditch and sump pits with the plastic liners. Thanks for any guidance! â G.E. 9/8/2014

Introduction Crawl Space Cleaning

Mold in crawl spaces is very common and can often be corrected with a little patience and hard work. We have been saying for years that there is no such thing as a crawl space with no mold growth in it. While this is probably an exaggeration, it certainly isnt far from the truth. It is a very common problem that, while oftentimes not a health issue, is a growing resale issue that requires attention prior to listing a home for sale.

The cost of cleaning up crawl spaces can be very expensive. Indiana Mold Remediation has always sought to find the best solution to mold problems that meet both remediation needs as well as account for the available resources of the homeowner. While we have worked hard to provide a high value for our cleaning services in crawl spaces, this guide is designed as an instruction manual for the do-it-yourselfers trying to address this hidden problem themselves and save the cost of hiring a professional. Keep in mind, cleaning up mold in a crawlspace can be very labor-intensive and quite messy, it isnt for the faint-hearted!

How Do I Remove It

If youre wondering how to get rid of white mold in your crawl space, youll need to assess the size of the problem. With a small emerging issue, you might be able to take care of it yourself, but you should not attempt anything over 30 square feet.

Use Personal Protective Equipment , even for small jobs. Youll need an N95 mask, gloves, and googles as a minimum since mold in the air can be as much as 10 to 1,000 times higher during removal/cleaning.

If the mold is on soil, and only a few square feet, you can dig down an inch to remove the affected area. After removal of the dirt, consider the installation of a plastic vapor barrier to help prevent reoccurrence.

Bleach may kill the mold but it doesnt prevent the spores from being airborne and you dont want to use bleach on porous materials. This action starves the mold of its food source.

Discoloration On Walls & Insulations

One of the easiest ways to identify a mold problem in the attic is by looking out for discolorations on insulations and walls. Mold growth mostly appears black or grey.

Whatever the color, youll notice a patch or discoloration which wasnt there before. When such is noticed, a closer inspection will be necessary before treatment commences.

What Causes Moisture In Crawl Space

Different sources could contribute to moisture in the crawl space. Lets take a look at some of the more common reasons below.

Condensation One of the biggest contributors to condensation in the crawl space is because of venting. Venting allows the outside air to enter the crawl space and come in contact with the inside air. Most often during the summer months, the crawl space becomes a breeding ground for mold and other harmful bacteria. The best way to combat condensation is to seal any vents or loose doors to prevent the outside air from being able to get in.

Water Seepage After heavy rainfall or when the snow begins to melt, all of that water-saturated in the soil will begin to seep up through the ground and come up into the crawl space. The best way to stop this from happening is to lay strips of heavy-duty plastic over the ground to act as a barrier, better known as crawl space encapsulation.

Gutters and Downspouts One of the biggest causes for a damp crawl space is one that could have easily been prevented, and that is by making sure that the gutters are clean and clear of debris and that the downspouts are properly directing water away from the foundation.

Leaking Pipes Plumbing pipes under your crawl space are another culprit that tends to get overlooked. Keep an eye on your utility bill and make sure there are no sudden spikes in usage.

However, a crawl space can all too easily collect moisture and become a breeding ground for mold.

What Chemicals And Tools Will Clean Mold In A Crawl Space

We have seen several genuinely confused people about what chemicals and tools will work the best to clean mold from a crawl space. Before we go through the exact steps needed to clean your crawl space of all mold thoroughly, we need to look at the exact tools you will need.

We always recommend that people have these at hand before entering the crawl space, as it can be a bother to go in only to find you are missing a tool. We have seen several people be surprised just how strong the normal chemicals found around the home are.

  • Bleach: The most effective household item that you can use to fight any type of mold will always be bleach. As a chemical, bleach is one of the most dangerous things you can have in your home and will be effective in killing any mold that may be growing or even spreading.
  • Ammonia: Ammonia has the same effect as bleach on mold, killing it instantly, but will usually work better on surfaces where bleach may be absorbed. We recommend never using the two together, choosing to use only one chemical each time when you enter the crawl space.
  • Hydrogen Peroxide: When both bleach and ammonia are just simply failing their job, we recommend that you use hydrogen peroxide. This is an acid and will kill everything it touches, including your hands, and cause rust on anything metal, but it will completely eradicate all types of mold.
