Do it Right — How To Keep Your Crawl Space Dry And Humidity In Check

Why Dry Your Crawl Space?

There is nothing worse than having a great day and coming home to a musty smell. You finally track it down to your crawl space sitting damp and moist. Ignoring this issue can lead to costly repairs. But don’t worry—this guide will provide the best steps to dry out your crawl space and keep humidity in check.

 

What Is Crawl Space Encapsulation? 

Crawl space encapsulation is the process of sealing your crawl space from moisture, pests, and mold. This process includes:

• Vapor Barrier to block moisture.
• Sealing Vents and Cracks to stop air and water infiltration.
• Adding Insulation to boost energy efficiency.

 

Advantages of Crawl Space Encapsulation

1. Humidity Control

Encapsulation keeps crawl space humidity between 30%-50%, helping prevent mold, mildew, and wood rot.

2. Better Air Quality

Blocking damp areas avoids harmful mold spores and bacteria from spreading throughout your home.

3. Energy Efficiency Upgrades

Your HVAC system can maintain indoor temperatures more efficiently, saving you money on energy bills.

4. Structural Protection

Excess moisture weakens wooden beams. Encapsulation helps preserve the structural integrity of your home.

5. Pest Prevention

Dry crawl spaces are less inviting to pests such as termites, rodents, and cockroaches.

 

Signs That Your Crawl Space Needs Attention

• Water Marks: Stains on walls or flooring.
• Excess Moisture: Water droplets or damp surfaces.
• Musty Odor: Persistent mildew-like smells in your home.

 

How to Dry Out Your Crawl Space

1. Remove Standing Water

Use a sump pump or wet vacuum to eliminate standing water. If necessary, seek professional assistance.

2. Fix Moisture Sources

• Repair plumbing leaks.
• Direct downspouts away from your foundation.
• Install a drainage system.

3. Improve Ventilation

Promote airflow using a dehumidifier or vents. In humid climates, focus on sealed encapsulation for moisture control.

4. Install a Vapor Barrier

Place a durable plastic sheet (10-20 mil) on crawl space floors and walls to create a moisture barrier.

5. Add Insulation

Choose fiberglass batt or rigid foam insulation to regulate humidity and reduce energy costs.

 

Tips on Effective Crawl Space Encapsulation

• Start with a Professional Inspection: Identify and fix existing issues before encapsulating.
• Use Durable Materials: Opt for thick, high-quality vapor barriers to ensure long-lasting results.
• Seal Gaps and Cracks: Close openings around vents, pipes, and other points of infiltration.
