Why Choose Insulation Commandos of Clarksville?

We’re not here to install a basic liner and rush to the next job. Every crawl space is different, so we take the time to identify moisture sources and recommend the right encapsulation system for your home.

Our free expert estimate process includes:

  • Detailed inspection for moisture, mold, standing water, damaged insulation, pests, and structural concerns
  • Assessment of vents, outside air entry points, humidity, and drainage conditions
  • Thermal imaging and precise measurements when appropriate
  • Evaluation of whether insulation removal or drainage work is needed
  • Evaluation of the correct dehumidifier for the space
  • Face-to-face consultation to explain our recommendations
  • Photos of problem areas for accurate estimating and installation planning

Professional Crawl Space Encapsulation

Every crawl space is different. To recommend the right long-term solution for your home, we inspect the space carefully and determine how moisture and humid air are entering.

During your free estimate, we measure the crawl space, inspect the existing insulation and structural materials, and evaluate any drainage, mold, or humidity concerns. This allows us to prepare the correct materials and complete the installation properly.

What’s Included in Our Crawl Space Encapsulation

Our complete encapsulation process includes:

  1. Inspection and assessment
    We evaluate moisture sources, insulation condition, accessibility, drainage, and visible structural concerns.
  2. Heavy-duty moisture barrier installation
    The crawl space receives a total 26-mil barrier system across the floor, with 20-mil barrier material installed on the walls and piers.
  3. Controlled ventilation and air-entry sealing
    Uncontrolled vents and moisture-entry points are sealed. We also install a 220 CFM humidistat-controlled fan in a designated foundation-wall opening to exhaust moisture-laden air and support the dedicated dehumidifier.
  4. Dedicated dehumidifier installation
    A crawl space dehumidifier actively controls humidity and helps maintain a conditioned environment throughout the year.
  5. Final walkthrough
    We review the completed installation and explain how to monitor and maintain the system.

Why a Conditioned Crawl Space Matters

Full encapsulation goes further by sealing the floor, walls, piers, and uncontrolled moisture-entry points while adding controlled ventilation and active humidity control.

The addition of a dedicated dehumidifier actively controls humidity instead of relying only on a passive liner. This creates a cleaner, drier, conditioned crawl space and provides a more complete solution for persistent moisture problems.

The Benefits of Crawl Space Encapsulation

A professionally installed crawl space encapsulation system does more than cover the ground beneath your home. It creates a sealed, conditioned environment designed to actively control moisture and humidity.

  • Support better energy efficiency and HVAC performance
  • Discourage pests attracted to damp conditions
  • Create a cleaner and easier-to-maintain crawl space

What Affects Crawl Space Encapsulation Cost?

The cost of encapsulating a crawl space depends on several factors, including:

  • Crawl space square footage
  • Accessibility and working conditions
  • Current moisture or mold severity
  • The condition of existing insulation
  • Whether damaged insulation must be removed
  • Whether drainage improvements are needed
  • The amount of sealing and barrier material required
  • The size and type of dehumidifier needed

We provide a detailed estimate after inspecting the crawl space. Financing options may also be available for qualifying homeowners.

Frequently Asked Questions

Encapsulation can be a valuable solution for homes with ongoing moisture, humidity, musty odors, or mold concerns. It provides more complete protection than installing a floor vapor barrier alone.

A vapor barrier primarily covers the ground to reduce soil moisture. Encapsulation seals the floor, walls, piers, vents, and outside air entry points and includes active humidity control with a dedicated dehumidifier.

Encapsulation helps reduce moisture and humidity that can contribute to mold growth. Any existing mold or water-entry problem should be evaluated and addressed as part of the project.

A dedicated dehumidifier actively maintains controlled humidity inside the sealed crawl space. It is a key part of creating a truly conditioned space.

A damp crawl space may contribute to musty air and elevated humidity inside the home. Encapsulation can help by reducing moisture and creating a cleaner, controlled environment beneath the living space.

Encapsulation focuses on moisture, outside air, and humidity control. Crawl space insulation focuses primarily on comfort and energy efficiency, though some homes may benefit from both services.
