Crawl space Encapsulation

Crawl Space Sealing • Vapor Barrier • Crawl Space Remediation

Crawl spaces, often neglected and unseen, play a surprisingly crucial role in your home's health. For homes built on a crawl space, studies show approximately 50% of the air you breathe comes from the crawl space. When poorly constructed, and particularly when moisture problems exist, crawl spaces can create a disaster for your home's Indoor Air Quality and even compromise the structural integrity of the home.

Moisture is the greatest enemy to any home. Because crawl spaces so commonly have moisture problems, these spaces become a breeding ground for mold (not to mention pests and rodents). Unfortunately, crawl spaces have been incorrectly built for decades. Traditional crawl space construction in humid climates is often the culprit, allowing moisture-laden air to freely enter through vents.

The proper solution is to seal the crawl space, AKA Crawl Space Encapsulation. When kept sealed and maintained properly, a homeowner can more effectively:

  • Manage moisture within the home
  • Prevent Mold
  • Maintain Healthy Indoor Air Quality
  • Reduce Pest Infestation
  • Lower Energy Costs

Benefits of Crawl space Encapsulation

Reduce Moisture

Prevent water damage and mold metabolizing organic materials, like wood framing.

Energy Efficiency

Crawl Space Encapsulation helps control the temperature within a crawl space, reducing the load on HVAC equipment.

Controls Pests

Vented crawl spaces provide the ideal environment for the infestation of pests, which are damp, dark, and cool spaces.

Better Indoor Air Quality

Reduces odors as well as mold spores and other allergens in the home.

Signs of Crawl space problems

Below are some of the common signs of how a crawl space problem can affect your home.

  • Musty odor in home
  • High energy costs to cool and heat the home
  • Poor Indoor Air Quality in the home
  • Mold inside the home
  • Sagging or uneven floors
  • Cracks in drywall, brick, or other wall structure
  • High relative humidity (RH) in crawl space
  • Moist insulation within crawl space
  • Sagging insulation in crawl space
  • Mold in crawl space
  • Water damage to joists and framing in crawl space
  • Pooling water in crawl space
Insulation in the crawl space falling due to being saturated with moisture

Mold & Moisture Assessment

We perform a thorough inspection of the crawl space for mold and any signs of excess moisture or water damage to structural components in the crawl space.

Mold Remediation & Moisture Management

Prior to sealing the crawl space, all mold must be remediated. All excess moisture must also be collected and removed from the crawl space.

Installation of a Crawl Space Vapor Barrier

We install a high quality vapor barrier to seal the crawl space and prevent moisture in the Earth from rising up and making contact with the underside of the home.

Sealing Crawl Space Vents

In the humid climate of the Southeast, we recommend all crawl space vents be sealed to keep humid air out.

When necessary:

Installation of a Crawl Space Dehumidifier

In very humid areas, such as the Southeastern United States, it may be necessary to add a permanent dehumidifier in the crawl space to manage moisture.

Sump Pump Drainage System

In situations where there is water pooling in a crawl space, a sump pump drainage system is recommended to collect the water and pump it out.

Mold & Moisture Frequently Asked Questions

What is mold?

Mold is a microscopic fungus that is part of the natural environment. Mold is all around us, indoors and outdoors. It is a necessary part of our ecosystem. While mold is necessary in the outdoor world, too much mold inside a structure can be dangerous and unsanitary. Mold reproduces through spores that float freely in the air. Once these spores land on a moist surface in the right conditions, mold will begin to grow.
