The Ultimate Sealed Crawl Space Solution in Atlanta

The dark, damp, and often overlooked area beneath your house, known as the crawlspace, plays a crucial role in your home’s overall health and energy efficiency.

While it may not be the most glamorous aspect of homeownership, the decision to seal your crawlspace can bring about a multitude of benefits, including reduced energy bills and enhanced indoor air quality.

In this all-inclusive guide, we’ll take you through the step-by-step process of achieving a perfectly Sealed Crawl Space.

Understanding Your Crawlspace

What Is a Crawlspace?

A crawlspace is a shallow, accessible area beneath a house that provides access to plumbing, electrical wiring, and sometimes HVAC systems. It’s typically constructed with a foundation of concrete blocks or poured concrete and is designed to allow just enough space for a person to crawl or kneel.

Common Issues in Unsealed Crawlspaces

Unsealed or poorly sealed crawl spaces can lead to a host of problems, including excess moisture, mold growth, and unwanted pest infestations. These issues can compromise your home’s structural integrity and indoor air quality.

Benefits of a Sealed Crawl space

A properly sealed crawlspace acts as a barrier between your home and the earth below, reducing the risk of moisture infiltration and creating a more comfortable living environment. It also helps prevent heat loss during the winter and reduces cooling costs in the summer.

Assessing Your Crawlspace

Before you start sealing your crawlspace, it’s essential to assess its condition thoroughly.

Inspecting Your Crawlspace

Begin by entering the crawlspace with proper safety gear and a flashlight. Look for signs of moisture, such as puddles or damp spots, as well as any visible mold or pest activity. Pay attention to any structural issues, like sagging floors or deteriorating insulation.

Measuring and Scoping the Project

Measure the size of your crawlspace to estimate the materials you’ll need for the sealing process. Determine whether your crawlspace is ventilated and if so, how many vents there are. This will help you decide if ventilation needs to be addressed during the sealing process.

Preparing for the Sealing Process

Before you get to work, it’s crucial to prepare properly.

Safety First

Safety should be your top priority when working in a crawlspace. Ensure proper ventilation and wear protective clothing, including a mask, gloves, and knee pads. Make sure someone knows you’re working in the crawlspace in case of an emergency.

Tools and Materials

Gather the necessary tools and materials, including a vapor barrier (usually made of heavy-duty plastic), sealant, insulation, a dehumidifier, and pest control products if needed.

Professional Help

If your crawlspace has extensive issues like structural damage or severe mold infestations, consider consulting with professionals who specialize in crawlspace remediation.

Steps to Seal Your Crawlspace

Now, let’s dive into the actual sealing process.

Installing a Vapor Barrier

A vapor barrier is a crucial component of a sealed crawl space. It prevents moisture from seeping into your home from the ground. Lay the vapor barrier on the crawlspace floor, overlapping seams, and securing it to the walls.

Sealing Vents and Openings

Seal off outside air by closing or covering vents and other openings to the crawlspace. Use weather-resistant sealant or insulated covers to ensure a tight seal.

Insulating the Crawlspace

Insulate the walls and sometimes the ceiling of the crawlspace to maintain a consistent temperature and prevent heat loss or gain. Common insulation options include rigid foam boards or fiberglass batts.


Controlling humidity is vital in a sealed crawl space. Use a dehumidifier to maintain an ideal humidity level, typically between 30-50%. Regularly empty and maintain the dehumidifier as needed.

Pest Control

Address any existing pest issues and take preventive measures to keep pests out of your sealed crawlspace. This may include sealing entry points and using pest repellents.

Maintenance and Monitoring

After sealing your crawlspace, it’s crucial to maintain and monitor it.

Regular Inspections

Schedule regular inspections to check for any signs of moisture, mold, or pest activity. Look for damage to the vapor barrier or insulation.

Humidity Control

Continue monitoring humidity levels and adjust your dehumidifier as necessary to keep them within the recommended range.

Benefits of a Sealed Crawl space

A sealed crawlspace offers several advantages:

Energy Efficiency: Reduced energy bills thanks to better temperature regulation.

Improved Indoor Air Quality: A sealed crawlspace prevents mold and allergens from entering your home.

Long-Term Savings: Less maintenance and potential savings on heating and cooling costs.

Increased Home Value: A sealed crawlspace can enhance your home’s market value.

Sealing the crawlspace under your house is a worthwhile investment in your home’s comfort, efficiency, and overall health. By following the steps outlined in this guide and staying vigilant with maintenance, you can enjoy the benefits of a properly sealed crawl space for years to come. Don’t overlook this often-neglected space; take action to ensure your home is in its best possible condition. Your crawlspace will thank you, and so will your wallet.
