Crawlspace Encapsulation Services in Eastern Pennsylvania

Protect Your Home from the Ground Up with Expert Crawlspace Encapsulation

Crawlspace Encapsulation If your crawlspace is damp, musty, or moldy—it’s more than just uncomfortable, it’s a threat to your home’s structure and indoor air quality. At 1 Dry Basement , we offer full crawlspace encapsulation services in Eastern Pennsylvania designed to permanently seal out moisture and protect your property from the ground up.

What Is Crawlspace Encapsulation?

Crawlspace encapsulation is the process of sealing your crawlspace from outside moisture and air using a heavy-duty vapor barrier, insulation, and drainage solutions. In simple terms, it transforms your dark, damp crawlspace into a clean, dry, and controlled environment. We install professional-grade vapor barriers across the floors and walls, seal vents and gaps, and control water intrusion using drain tile systems, sump pumps, and dehumidifiers where needed. This creates a moisture-resistant barrier between your home and the earth below, preventing mold, mildew, pests, and wood rot.

Encapsulating your crawlspace has major benefits that go far beyond just eliminating odors. Here's what you can expect:

Benefits of Encapsulation

Moisture and Mold Prevention

By blocking humidity from the ground and surrounding soil, encapsulation stops mold before it starts. This protects your floor joists,beams and insulation from rot and microbial growth.

Improved Indoor Air Quality

Roughly 50% of the air on the first floor of your home comes from your crawlspace. Sealing it up means you're breathing cleaner, healthier air with fewer allergens and irritants.

Energy Efficiency

A sealed crawlspace reduces the amount of outside air entering your home. That means your HVAC system doesn’t have to work as hard to heat or cool, leading to noticeable energy savings.

Pest Control

Encapsulation keeps out rodents, insects, and termites by removing the moisture and entry points they rely on. It's one of the best proactive defenses against infestation.

Structural Protection

Continuous exposure to moisture leads to wood decay and foundation problems. Crawlspace encapsulation protects your investment and can add years to your home’s lifespan.

Increased Property Value

A clean, dry crawlspace adds value to your home and peace of mind for future buyers.

Crawlspace Encapsulation FAQ

Please reach us at onedrybasement@gmail.com if you cannot find an answer to your question.

What is crawlspace encapsulation?

Crawlspace encapsulation is the process of sealing your crawlspace from outside moisture, pests, and contaminants. It involves installing a heavy-duty vapor barrier across the floor and walls, sealing vents and gaps, and often including drainage systems, insulation, and a dehumidifier for full moisture control.

Why should I encapsulate my crawlspace?

Encapsulation helps prevent mold growth, wood rot, poor indoor air quality, and high humidity levels inside your home. It also makes your crawlspace cleaner, more energy-efficient, and can protect your home’s structure from long-term moisture damage.

How does crawlspace encapsulation tie into basement waterproofing?

A wet or damp crawlspace can contribute to water problems throughout the foundation. Crawlspace encapsulation often starts with drain tile installation, sump pumps, or foundation crack repair—key parts of a complete basement waterproofing system. Sealing the crawlspace without addressing water entry first is never recommended.

What materials are used?

We use professional-grade, woven 10-mil and 20-mil vapor barriers, which are more tear-resistant and durable than thinner plastic liners. All seams are sealed, and wall barriers are mechanically fastened and taped to ensure a long-lasting hold. We also use foam board insulation and seal any gaps for energy savings.

Do I need a dehumidifier in my encapsulated crawlspace?

Yes, in most cases. Even with a vapor barrier, some moisture can still enter from the air or surrounding materials. A crawlspace-rated dehumidifier helps keep humidity below 60%, which is ideal for preventing mold and mildew.

How long does crawlspace encapsulation take?

Most projects take between 1 and 3 days, depending on the size of the crawlspace and whether drainage or repairs are needed first

Will this improve my indoor air quality?

Absolutely. Up to 50% of the air you breathe on the first floor comes from your crawlspace. Encapsulation helps block mold spores, dust, allergens, and musty odors from entering your living space.

How much does it cost?

Costs vary depending on the size of your crawlspace, materials used, and whether waterproofing work is needed. We offer free consultations and estimates to give you a clear picture of the investment before work begins.

Do you offer warranties?

Yes. We stand behind our work with warranties on both materials and labor. Details vary depending on the scope of your project, and we’re happy to walk you through what’s covered.
