Crawl Space Encapsulation

Crawl space encapsulation is a process that completely seals the area beneath your home to protect it from moisture, mold, odors, and pests. This service is essential to maintain a healthy indoor environment, improve energy efficiency, and prevent structural damage.
What does it envolve?

The encapsulation process includes:

  • Cleaning and inspection of the crawl space.
  • Installation of a vapor barrier on the ground and walls.
  • Sealing of vents and air leaks.
  • Proper thermal insulation.
  • Installation of specialized dehumidifiers, if needed.
Types of Encapsulation
  • Partial Encapsulation: Ideal for basic moisture control and mold prevention.
  • Full Encapsulation: Recommended for maximum protection, including vapor barrier, full sealing, insulation, and active humidity control.

Our 8 Step Crawl Space Encapsulation Process

Step 1

Inspection and Diagnosis

We perform a complete assessment of the crawl space to identify the source of moisture, mold, or structural issues, allowing us to design a customized encapsulation plan for your home.

Step 2

Cleaning and Removal

We thoroughly clean the area, removing debris, trash, and old or damaged insulation from the ground to ensure a smooth, lasting vapor barrier installation.

Step 3

Moisture and Drainage Correction

We address standing water issues by installing sump pumps or drainage systems as needed to redirect water away from your home.

Step 4

Air and Vent Sealing

We hermetically seal all foundation vents and wall cracks with spray foam to block humid or cold outside air from entering.

Step 5

Heavy Duty Vapor Barrier

We cover 100% of the ground and walls with a heavy-duty, reinforced liner (12 to 20 mil) and seal all seams to lock out ground moisture permanently.

Step 6

Thermal Insulation Barrier

We install thermal insulation on the foundation walls to stabilize temperatures and reduce heating and cooling costs.

Step 7

Honeywell Dehumidification System

We integrate a professional-grade Honeywell dehumidifier designed to automatically keep humidity levels below 50% and prevent mold growth.

Step 8

Final Testing & Quality Check

We test the complete system, verify the seal, and take final moisture readings to ensure optimal performance and long term protection.
