The Problem

Why is an unsealed crawl space a problem?

An unsealed crawl space acts like a “lung” for your home, pulling in moisture, allergens, and unconditioned air from the earth and circulating them upward into your living areas. Because of the stack effect, roughly half of the air you breathe on your first floor originates in this dark, damp area, making its condition vital to your home’s overall health and structural integrity.

  • Compromised Air Quality: An unsealed crawl space can allow mold spores, radon gas, and musty odors to seep into your living space, triggering allergies or respiratory issues.
  • Structural Deterioration: Uncontrolled humidity leads to condensation on wooden floor joists, eventually causing wood rot, sagging floors, and rusted metal supports.
  • High Energy Costs: Infiltrating outside air forces your HVAC system to work significantly harder to combat humidity in the summer and cold floors in the winter.
  • Pest Infestations: Damp, unsealed environments serve as an open invitation for termites, cockroaches, and rodents to nest and eventually find pathways into your home.

Addressing these issues through encapsulation doesn’t just protect your foundation… It creates a more comfortable environment and preserves your home’s long-term resale value. By sealing the space with Dakota Radon Pros, you transform a hidden liability into a clean, controlled part of your home’s building envelope.

common issues

Can my crawl space cause radon & Mold growth?

Yes, an unsealed crawl space is one of the most common contributors to high radon levels and mold growth within a home. Because this area sits directly on the soil and is often damp and poorly ventilated, it acts as a collection point for hazardous gases and fungi that eventually migrate into your living space.

Radon Intrusion

Radon gas seeps directly through dirt floors and foundation cracks, concentrating in the crawl space.

Moisture-Driven Mold

Ground vapor and humid air creates a damp environment where mold thrives.

Pest Infestations

Unsealed vents and gaps invite rodents and pests that chew through wood, destroy insulation, and gnaw on wiring.

General Deterioration

High moisture levels cause premature rust and corrosion on plumbing pipes, metal connectors, and HVAC ductwork.

Frequently Asked Questions

Everything you need to know about crawl space encapsulation and our services. We’ve compiled answers to the most common questions we receive from homeowners and property managers. If you have additional questions not covered here, our team is always happy to provide personalized guidance for your specific situation.

How does crawl space encapsulation affect my energy bills?

Yes, you may see a drop. This occurs because an unsealed crawl space is a major source of energy loss due to the stack effect. By sealing this area, you effectively move the “envelope” of your home from the first floor down to the foundation.

Furthermore, because many HVAC ducts are located in the crawl space, encapsulation prevents them from sitting in an environment of extreme temperatures. Instead of losing heat or cool air through the duct walls into a 100-degree or 30-degree crawl space, the ducts operate in a “conditioned” environment. This stabilization not only lowers monthly costs but also extends the lifespan of your expensive HVAC equipment by reducing its total workload.

How long does crawl space encapsulation take?

For smaller crawl spaces, the job could take as little as half a day, while larger areas may take a few days. The exact timeline depends on the size of your home and the current condition of the space. The process is broken into several distinct phases.

The first phase involves removing old, soggy fiberglass insulation, clearing out debris, and leveling the soil. If your crawl space has standing water or mold, remediation must happen here, which can add extra time.

The final phase is usually dedicated to the mechanical components: installing the dedicated crawl space dehumidifier, setting up a condensation pump or sump pump, and ensuring the electrical work is up to code.

Can I still use the crawl space for storage after encapsulation?

Yes, you can use an encapsulated crawl space for storage, and in many ways, it becomes a much better storage environment because it is cleaner, drier, and less prone to pests.

That said, it’s still always best to use airtight plastic bins for storage, rather than cardboard boxes. Even in an encapsulated space, cardboard can absorb trace amounts of moisture and provide a food source for silverfish or the occasional stray insect. In addition, avoid storing flammable materials, chemicals, or firewood.

Finally, always leave a clear pathway to the dehumidifier and the sump pump. Maintenance technicians will still need to access these components for annual service.

How long does crawl space encapsulation last?

When completed by a professional, crawl space encapsulation typically lasts between 15 and 25 years.

The most durable component is the reinforced polyethylene vapor barrier. These heavy-duty 12–20 mil liners are designed to remain puncture-resistant and effective for over 20 years.

To maximize the life of the entire system, it’s a good idea to conduct visual inspections from time to time to ensure seam tapes remain secure and everything looks to be in order.
