Crawl Space Encapsulation in Greenville, SC

Crawl Space Encapsulation in Greenville, SC

The air in your home might be coming from a place you rarely think about. In Greenville, where summer humidity clings to everything and the clay-rich soil traps moisture, a damp crawl space can quietly spread problems into every room above it. From musty air and rising energy bills to mold and wood rot, an unsealed crawl space does more than just stay hidden—it puts your whole home at risk.

At ’58 Foundations & Waterproofing, we’re the crawl space encapsulation company Greenville homeowners trust when it’s time to take control of what’s happening beneath their floors. We don’t just seal your crawl space—we transform it into a clean, dry, protected environment that supports the health, efficiency, and value of your home.

Why Crawl Space Moisture Is a Bigger Problem Than It Looks

Even though you can’t see it every day, your crawl space plays a major role in your home's air quality and structural health. Without proper protection, it becomes a magnet for moisture. That dampness fuels mold growth, weakens floor joists, and invites pests. In homes across Greenville, we often find insulation falling apart, standing water pooling after storms, and musty odors drifting upward into bedrooms and living spaces.

More than 40% of the air you breathe indoors can come from your crawl space. That means sealing it off from outside humidity isn’t just about comfort—it’s about protecting the people inside.

Our Crawl Space Encapsulation Services in Greenville

Every encapsulation system we install is tailored to your home’s layout, condition, and moisture level. After a full inspection, we may recommend a combination of the following solutions:

• Heavy-Duty Vapor Barrier
  We line the floors and walls of your crawl space with a thick, reinforced barrier that blocks moisture from the soil and surrounding air. It creates a sealed, controlled environment that keeps dampness out year-round.
• Vent Sealing and Gap Closure
  We close off outside vents, holes, and openings to prevent outside air, pests, and humidity from entering the crawl space.
• Dehumidifier Installation
  For added protection, especially in homes with persistent humidity, we install crawl space dehumidifiers that maintain healthy moisture levels and improve air quality throughout the home.
• Insulation Upgrades
  Once the space is sealed, we can replace old or damaged insulation with materials designed to perform better in enclosed, moisture-controlled spaces, helping your HVAC system run more efficiently.

All work is performed by our in-house Certified Foundation Specialists—not subcontractors—and backed by our Life-of-the-Structure Warranty for long-term peace of mind.
