The crawl space isn’t really inviting. You don’t go down there very often. Still, the whole house smells musty, and you’ve looked everywhere else. You grab a flashlight and take a peek. Right away, you can see the source of that unpleasant odor. It’s there in the crawl space.

You know how to deal with the stuff under a sink. Do you know how to get rid of mold in a crawl space?

As a DIY project, crawl space mold remediation is usually manageable, but you have to be very careful. You need personal protection gear, the right cleaning products and plenty of patience.

Mold in Crawl Spaces: The Health Issues

When you tackle mold in crawl spaces, it’s dangerous for the same reasons mold thrives under your home’s first floor. The area is dark, humid and badly ventilated. The conditions are ideal for a mold outbreak that can pose serious health hazards in a compact space.

Mold type is another health consideration. White mold in a crawl space is easier to remove than toxic Stachybotrys chartarum. DIY removal of this strain of black mold in a crawl space can be very dangerous to your health. Before starting your cleanup job, think about testing the mold so that you know exactly what you’re dealing with.

How to Kill Mold in Crawl Spaces: 6 Steps to a Cleaner Home

When we’re asked about how to get rid of mold in crawl spaces, we always stress the importance of personal protection. Before you begin any DIY mold removal project, protect your health with an OSHA-rated respirator or face mask, non-vented goggles, heavy gloves and throw-away coveralls.

1. Assess the Situation

Wearing your protective gear, assess the extent of mold in the crawl space. Set up lights, and lay down plastic sheets to catch mold as it’s cleaned from surfaces. If the job seems too big, contact a mold remediation company right away.

2. Clean With a Foaming Spray

Spray affected areas with a foaming cleaning product specially formulated for mold removal. Allow it to expand and loosen mold, and then begin carefully cleaning surfaces.

3. Soak With a Mold Killer

Soak any remaining thin coats of mold with a homemade mold-killing mixture or mold-removal cleaner. Commercial products are usually more effective, and they often remove mold stains too.

4. Scrub Off Residue

Let affected areas dry, and then use a stiff bristle brush to scrub away any remaining mold. This can be a time-consuming process, but you want to remove as much mold residue as possible.

5. Dispose of Everything

Carefully fold up your plastic sheeting, and seal it in a heavy trash bag. Dispose of coveralls, brushes and any other contaminated gear the same way. Keep bagged items stored outside until trash pickup.

6. Control Crawl Space Climate

There are several different ways to address crawl space climate, but a dehumidifier is usually the most effective and affordable solution. Consider installing a model designed to operate in tight places. Make crawl space inspection a part of spring and fall home maintenance.

Don’t Risk Your Health

As sure as you are of your DIY talents, don’t risk taking on a job that’s too big or too dangerous. We strongly recommend calling in a mold remediation service if:

• Affected areas include damaged or rotted wood.
• Mold covers multiple areas larger than 3 square feet.
• You or any family members deal with allergies or respiratory problems.

Bringing in a mold remediation specialist also addresses issues like identifying and eliminating mold sources and repairing and replacing affected materials.
