DO: Seal Any Cracks or Gaps in the Foundation 

Before you start cleaning your crawl space, check for any cracks or gaps in the foundation that need to be sealed. These cracks can lead to water leakage and allow pests into the area. To help prevent this from happening, use caulk or spray foam insulation to fill in any gaps or cracks before beginning your cleaning process. 

DO: Install Vapor Barriers 

A vapor barrier is a layer of plastic sheeting that helps protect against moisture buildup in the crawl space. Installing a vapor barrier also helps reduce mold growth, as it prevents condensation from forming on surfaces in the area. When installing a vapor barrier, make sure that it covers all walls and floors completely so that no moisture can get through. 

DO: Check for Mold Growth 

Mold can be dangerous if left unchecked, so it's important to check your crawl space regularly for signs of mold growth. If you find any areas where mold has started to grow, use a fungicide to treat it immediately before it spreads further throughout the area. Additionally, try using a dehumidifier in the area if possible; this will help reduce humidity levels, which can help slow down mold growth over time. 

DO: Inspect for Pests

It's normal to expect to have to deal with insects and other pests when working in a dim area close to the ground. Make sure you also check for infestations as part of your cleaning. For instance, the smells you've noticed throughout your house could be the result of dead rodents that have consumed poisonous bait. Even if they cannot enter your home, rodent infestations can still be dangerous. This is because inhaling rodent feces and urine can allow harmful pathogens to enter your body.

DON'T: Use Bleach or Ammonia-Based Cleaners

Bleach and ammonia-based cleaners may seem like they'll do an effective job of killing germs in your crawl space, but they can actually cause more harm than good by releasing toxic fumes into the air. Instead of using these chemicals, opt for natural solutions such as baking soda or vinegar mixed with water to clean surfaces instead. 

DON'T: Forget to clear the debris.

Cleaning your crawl space includes removing debris, which is a crucial step. You might not be able to get to it if you don't clear away junk, construction debris, and old trash. It's also crucial to keep in mind that in order to check for pests and water damage, you or a professional will need to descend. If debris like splintered wood or broken glass isn't cleaned up right away, it could cause damage.

Don't: Avoid Small Leaks

It's critical to understand that even a small leak or water drainage issue can result in significant issues down the road as you inspect the remainder of your crawl space. Even if they seem unimportant at the time, take note of any leaks or water damage you see. Take as many pictures as you can so you can later show them to an expert for additional review.

Preparation

The following actions can help you get ready to clean your crawl space

1. Gather your tools: You'll need cleaning supplies like a broom, dustpan, mop, and disinfectant, as well as safety equipment like a face mask, gloves, and protective eyewear.
2. Turn off the power: In order to prevent any electrical mishaps, it's crucial to turn off the power in the crawl space before entering.
3. Examine the crawl space: To look for any potential dangers, such as any standing water, structural problems, or high mold concentrations. It might be best to hire a pro to handle the cleaning process if you notice any of these problems.
4. Remove trash: Start by clearing the crawl space of any trash, debris, or insulation that has fallen.
5. Fix any leaks or moisture problems: In order to avoid further harm, it's crucial to fix any plumbing leaks or moisture problems in the crawl space before cleaning.
6. Ventilate the crawl space: This will help to lower moisture levels and stop the development of mold and mildew. Before cleaning, make sure the crawl space is properly ventilated.
7. Prepare your cleaning solutions: As directed by the manufacturer, combine water with a mild detergent or commercial disinfectant. When handling chemicals, be sure to put on protective eyewear and gloves.

Cleaning Process

Crawl spaces are usually dark and damp areas of the home that, unfortunately, can be breeding grounds for pests, mold, and mildew. It's important to keep this space clean and well-maintained in order to protect your home from damage. But how do you go about cleaning your crawl space? Here’s a step-by-step guide to making sure you get the job done right.

Step 1: Wear Protection

Before entering the crawl space, wear gloves, a face mask to block dust and debris, and protective eyewear. This will prevent crawl space cleaning injuries and illnesses.

Step 2: Survey

After donning your gear, inspect the area. Bring a flashlight to see what needs cleaning. Check for mold, mildew, and rodents. Water leakage or other water damage may indicate a plumbing problem. Before cleaning, note any issues.

Step 3: Clean Up Debris 

After identifying what needs cleaning, start doing it! A vacuum cleaner with an extension attachment can reach tight corners and remove dirt, dust, cobwebs, dead leaves, and other debris from your crawl space floor and walls. 

Before cleaning your crawl space, use a wet/dry vacuum or sump pump to remove all standing water from broken pipes or flooding. Use bleach and a scrubbing brush/mop head combo tool to clean mold or mildew before drying with towels or rags.
