Protect Your Home With Professional Crawl Space Encapsulation

Reduce moisture, improve indoor air quality, and create a cleaner, more energy-efficient crawl space environment.

Moisture Protection, Energy Efficiency & Healthier Indoor Air

Crawl spaces are one of the most overlooked areas of the home, yet they can have a major impact on indoor air quality, moisture control, comfort, and energy efficiency. When crawl spaces are exposed to outside air and ground moisture, they can become damp environments that contribute to mold growth, musty odors, pest activity, and structural damage over time.

Crawl space encapsulation is designed to seal and protect the crawl space from outside moisture and uncontrolled airflow. A complete encapsulation system typically includes a reinforced vapor barrier, sealed vents, insulation improvements, air sealing, and moisture control solutions that help create a cleaner and more energy-efficient environment beneath the home.

Why Crawl Space Moisture Is a Problem

Unsealed crawl spaces often allow moisture from the soil and outside air to enter the home. Over time, excess humidity can lead to mold growth, wood rot, damaged insulation, musty odors, and poor indoor air quality.

Many homeowners are surprised to learn that air from the crawl space can travel upward into the living areas of the home. Because of this, moisture and contamination beneath the house can directly affect comfort and air quality indoors.
Excess crawl space moisture may contribute to:
  • Musty odors inside the home
  • Increased humidity levels
  • Mold and mildew growth
  • Wood rot and structural damage
  • Higher energy bills
  • Pest and rodent activity
  • Damaged or falling insulation


When properly installed, crawl space encapsulation helps reduce moisture problems while improving the overall condition of the home.

Our Crawl Space Encapsulation Process

1. Crawl Space Inspection

We evaluate moisture levels, insulation condition, airflow, and structural concerns.

2. Cleanup & Preparation

Damaged insulation, debris, and contaminated materials are removed if necessary.

3. Vapor Barrier Installation

A reinforced 12-mil or 20-mil plastic barrier is installed to help block ground moisture.

4. Air Sealing & Vent Protection

Open vents, gaps, and crawl space leaks are sealed for better protection.

5. Insulation & Moisture Improvements

Insulation and moisture-control solutions are added to improve efficiency and comfort.

Signs Your Crawl Space May Need Encapsulation

Many crawl space problems develop gradually over time. Common warning signs include:

  • Musty odors throughout the home
  • Sagging or cold floors
  • Visible moisture beneath the house
  • Mold or mildew growth
  • High indoor humidity
  • Increased pest activity
  • Damaged insulation
  • Rising heating and cooling costs

If these issues are left untreated, moisture problems can continue affecting both the crawl space and the living areas above it.

How Encapsulation Protects Your Home From Rodents

An unsealed crawl space is an open invitation for mice, rats, and other pests to nest under your home, destroying your insulation and creating unhealthy air quality. Standard insulation alone won’t keep them out. By pairing high-quality insulation with a fully sealed crawl space encapsulation system, you eliminate their entry points, protect your home from pest damage, and create a cleaner, healthier environment beneath your house.

Frequently Asked Questions

Why do Denver homes need crawl space encapsulation if Colorado has a dry climate?

While Colorado is semi-arid, Denver-area soils (especially expansive bentonite clay) trap moisture from melting snow and spring rains right against your foundation. This trapped moisture evaporates upward into your crawl space, causing hidden mold growth, wood rot, and musty odors that eventually travel up into your living areas. Encapsulation seals out this ground moisture permanently.

Yes, significantly. During cold Front Range winters, freezing air drafts into unsealed crawl spaces, making the floors right above them icy cold. This forces your furnace to work overtime. By combining high-performance insulation with precision air sealing and encapsulation, you trap a pocket of stabilized air under your house, lowering your heating and cooling costs by up to 15% to 20%.

 Yes. The EPA ranks Denver and the surrounding Front Range as a high-risk zone (Zone 1) for radon gas. Radon naturally escapes from the soil and enters your home through exposed dirt crawl spaces. Installing a heavy-duty, professionally sealed 12-mil or 20-mil vapor barrier acts as an excellent primary layer of defense to block radon and soil gases from entering your breathing air.

Absolutely. Beyond protecting your family’s health by eliminating mold spores and pest nesting grounds, encapsulation protects your foundation from costly structural wood rot. Furthermore, a clean, fully encapsulated crawl space serves as valuable, dry storage space and drastically increases your home’s resale value when it comes time to sell in the competitive Colorado real estate market.
