Crawl Space Encapsulation

Seal Out Moisture, Mold, and Odors — Protect Your Home from the Ground Up

Unsealed crawl spaces are a hidden danger. Excess moisture, poor ventilation, and exposed soil can lead to mold growth, wood rot, and even foundation damage. At PiersPro, we offer professional crawl space encapsulation services that create a dry, sealed, and healthy environment beneath your home.

What Is Crawl Space Encapsulation?

Encapsulation is a complete sealing system designed to isolate your crawl space from the outside environment. It includes:

• Heavy-duty vapor barrier installed over soil and foundation walls
• Sealing of all vents and air leaks
• Moisture and humidity control with optional dehumidifiers
• Insulation upgrades to improve energy efficiency

The result? A clean, dry, and sealed subfloor space that strengthens your home’s structure and air quality.
