How To Remove Mold From Crawl Space Floor Joists

Assessing Damage From The Mold Growth

Mold in a Crawl Space and Floor Joist

The dangers of mold to your home go far beyond health concerns. If mold is left unaddressed, you run the risk of serious damage to the floor joists, floorboards, and other support structures of your house. Wood that retains moisture is weakened, and an invasion of mold takes the damage even further. The boards and beams can crack and separate as the fungus eats through the materials. You may not know that your flooring is unsafe until its too late.

After you have thoroughly cleaned up the mold, you need to assess the area for damage. Look at the joists or boards and determine if there are soft spots or areas of deterioration. You want to have any structural concerns evaluated by a professional contractor, as you may need some parts of board, beams, or flooring replaced for safety.

Will Bleach Kill Mold In Crawl Space

Yes, bleach will kill mold in a crawl space, and it will also kill almost everything else that is causing a problem. Bleach is almost pure chlorine with only a few other things mixed in, and organic life cannot survive in this mixture of chemicals, which is why people often use bleach to disinfect items.

You can use bleach to kill almost all types of mold on any surface throughout your home, with many people using bleach to control the mold in their bathrooms. We recommend doing this as well as it will keep your shower and toilets as clean as they can be without resorting to more dangerous chemicals.

It is vital to understand that bleach is one of the strongest chemicals you can use, but it is not the strongest. When going to hardware stores or specialist chemical providers, you can often find dangerous chemicals to handle without gloves but completely eradicate all mold within seconds.

What To Wear To Remove Mold Safely

Before even choosing a cleaning product, you should know what kind of safety equipment to wear to clean a moldy surface.

The basic equipment consists of an N-95 respirator, goggles or eye protection, & protective gloves with long cuffs. Long pants, a long sleeved shirt and waterproof boots are important to wear as well. Closed toed shoes are a good substitute for boots, especially if you are working on a small area of mold.

Mold is a respiratory irritant and allergen, so a mask with a N-95 respirator is important. A simple dust mask will NOT protect you from the mold spores. To learn more about face masks see our post: In-depth Guide to Face Masks: Allergies, Grass Cutting, and COVID-19.

Brushes Scrubbers And Abrasive Material

Once everything has been sealed, and you have read the instructions on the chemicals, it is time to start cleaning everything. Scrub the foundation walls with plastic brushes, flat metals with sponges and cloths, plastics with soft brushes, and every other hard surface with the hardest brushes.

Choosing which brushes work the best for your crawl space will require a judgment call from you as everyone has different types of crawl spaces. People often prefer to use one plastic brush throughout the crawl space to get everything clean.

What Is A Crawl Space

Crawl spaces are a type of foundation where the ground floor of a home is raised 1-3 feet off of the ground. This foundation type is used in areas where the freeze-thaw cycle poses risks to other foundation types such as slab-on-grade or basements, or where significant moisture may affect your foundation over time. Crawl spaces may also be used in locations with sandy soil, which is common in the coastal areas of the United States.

What Problems Do Mold Cause

A mold problem can be detrimental to your health and your home. Mold can cause throat and eye irritation, nose stuffiness, trouble breathing, and even more severe reactions for those with mold allergies. For your home, mold and mildew are often caused by water damage. A mold infestation is a sign that there is too much moisture in your home which can lead to deteriorating structures, expensive repairs, and decreased home value.

Why Does Mold Form In Crawl Spaces

Before we outline how to get rid of mold in crawl space, its helpful to understand why mold forms in this area in the first place.

The most important thing to understand is that mold cant form without water. If mold is present, that means water is also present. For mold to form on common building materials takes time, which means that any mold in your crawl space is preceded by a time where the wood or insulation in that area is saturated and kept wet. This can occur from a consistently high humidity level where moisture buildup is frequent in the air.

Mold is specifically a problem in vented crawl spaces. In a vented crawl space, small vents are placed along the perimeter of the crawl space to facilitate passive air circulation with the outside. During cooler months this works adequately, but during warmer months it creates a moisture problem.

In warmer months, the ground and air in a crawl space are a few degrees cooler than the outside air. As that warmer outside air enters the crawl space it begins to cool. Once that warm air hits the dew point it will form condensation. In most vented crawl spaces this condensation will form on the underside of the subfloor, on the floor joists and insulation placed there. As the moisture along the floor joists and insulation persists, it will begin to form mold.

    Do Small Tight Crawl Spaces Cost More To Fix

    Should I Remove Dirt From My Small Tight Crawl Space

    Many have asked us questions over the years about removing dirt from the crawl space. Most are interested in leveling the dirt floor of the crawl space. Not lowering it for access. Either way, removing dirt from the crawl space could create a flooding problem. When compacted soils are loosened, there is less resistance for water to make its way into your crawl space. This is part of the reasons homes flood in the first place.

Once the water finds a way in, it usually will not stop.
