Moisture Control Starts Below Your Home

Why Crawl Space Encapsulation Is Essential in Raleigh

Raleigh homes face year-round moisture challenges due to regional humidity, temperature fluctuations, and soil conditions. Vented crawl spaces allow damp air to enter, creating the perfect environment for mold, mildew, wood rot, pests, and contaminated air. The solution is crawl space encapsulation raleigh which seals the crawl space completely and maintains proper humidity levels.

Our process is designed to protect your home through:

Moisture control

Humidity reduction

Improved indoor air quality

Structural preservation

Long-term waterproofing solutions

Whether you need full encapsulation, crawlspace remediation, or advanced moisture management, Triangle Radiant Barrier delivers lasting results you can trust.

The Importance of Crawlspace Remediation Before Encapsulation

Before installing a vapor barrier or insulation system, your crawl space must be properly restored through crawlspace remediation. This involves removing damaged insulation, cleaning contaminated surfaces, eliminating mold, sealing vents, and correcting moisture issues. By addressing these underlying problems first, your home gains the maximum benefit from encapsulation.

Common remediation steps include:

Removing moldy or deteriorated fiberglass insulation

Sealing all structural gaps and penetrations

Sanitizing surfaces

Installing new vapor barrier systems

Preparing the crawl space for conditioning

Proper remediation ensures that your crawl space remains clean, dry, and structurally sound for decades.

Our dehumidification systems:

When combined with sealing and insulation, dehumidification provides a complete moisture-control solution.

Sealing Out Moisture. Sealing In Comfort.

What Is an Encapsulated  Crawl Space?

An encapsulated crawl space is a fully sealed, insulated, humidity-controlled environment designed to keep moisture out and conditioned air in. Unlike traditional vented crawl spaces, encapsulated spaces stay clean, dry, and protected from outside conditions.

Key features of an encapsulated crawl space include:

Sealed foundation vents

Heavy-duty vapor barrier

Wall and floor insulation

Air sealing

Moisture management system

Interior conditioning or dehumidification

The result is a healthier, more energy-efficient home with long-term structural protection.

Frequently Asked Questions

What is the best insulation for crawl spaces?

The best insulation options for crawlspaces are ones that both insulated and air seal (prevent convective heat transfer), such as rolled insulation (such as CrawlBarrier), closed cell spray foam, or rigid foam board (such as Bora-Foam). Fiberglass insulation does not air seal, so it is by far the least performing type of insulation for a crawl space.

What is the best way to insulate a crawl space?

The best way to insulate a crawl space is by sealing the foundation vent openings and installing a product that insulates and air seals the foundation walls. This is best done with rolled insulation (like CrawlBarrier), closed-cell spray foam, or rigid foam board (like Bora-Foam). This insulates the crawlspace and extends your home’s thermal and pressure boundary to the crawl space, moderating crawl space temperature and humidity.

What is the average service life of crawl space insulation types?

Fiberglass insulation typically lasts about 10 years before needing repair or replacement. It deteriorates faster in a crawl space with high humidity, particulates, and rodent activity.

Insulation types that seal or encapsulate a crawl space are made with materials that do not deteriorate over time, such as rolled insulation (like CrawlBarrier), closed-cell spray foam, or rigid foam board (like Bora-Foam). These products generally last the life of the crawl space, with lifetime warranties against degradation or delimitation.

Should I encapsulate my crawl space?

In a humid climate, crawl space encapsulation offers benefits like:

Preventing mold growth
Improving indoor air quality
Increasing energy efficiency by reducing heating/cooling costs
Protecting the home’s structural integrity
Extending the service life of crawl space utilities (e.g., HVAC, water heater)
Enhancing your home’s resale value.

What is guarantee and warranty on TRB’s encapsulated crawl spaces?

With a dehumidifier installed, TRB guarantees the performance of its encapsulated crawl spaces in terms of moderating relative humidity and preventing mold growth. TRB also offers a ‘No Mold’ Guarantee to customers who subscribe to TRB’s Annual Service Plan.

TRB provides a limited lifetime warranty on installed CrawlBarrier insulation, closed-cell Spray Foam insulation, and Bora-Foam insulation, as well as on all 10-mil Reinforced or better crawl space vapor barriers. The warranty covers both labor and materials to repair or replace any degraded or delaminated products for as long as you own your home. The lifetime warranty is transferable to a buyer if on TRB’s Annual Service Plan.

Will encapsulating your crawl space improve HVAC efficiency?

Encapsulating your crawlspace moderately improves HVAC efficiency but less than improving your attic’s air sealing and insulation. Crawl space encapsulation primarily enhances indoor air quality, protects structural integrity, and extends the service life of utility systems in the crawl space (e.g., HVAC, water heater).

For energy efficiency, consider attic improvements before crawl space encapsulation.

Is air induction or a dehumidifier better for moderating crawlspace relative humidity?

Air induction uses a small amount of conditioned air from your HVAC system to moderate crawl space temperature and humidity. It is less expensive to install than a dehumidifier.
