Crawl Space Insulation and Encapsulation

Eliminate Moisture, Mold, and Energy Loss

Protect your home's foundation and improve indoor air quality with professional crawl space insulation, moisture control, duct cleaning, and sealing solutions.

Your crawl space affects your entire home's comfort, energy efficiency, and air quality. Uninsulated or improperly insulated crawl spaces allow moisture infiltration, create cold floors, and waste energy. Our crawl space insulation solutions address these problems at the source.

  • Standing water

  • Mold and mildew growth

  • Pest infestations

  • Frozen pipes

  • Poor indoor air quality

Encapsulation vs. Vented Crawl Spaces

Modern building science favors conditioned crawl spaces over traditional vented designs. Our encapsulation approach creates a controlled environment that:

  • Increases comfort, evens out temps

  • Reduces humidity levels throughout entire home

  • Eliminates condensation and mold growth

  • Improves indoor air quality

  • Increases energy efficiency

  • Prevents intrusion from spiders, bugs, and critters

  • Creates usable storage area and clean, comfortable access for maintenance

Health Benefits:

  • Cleaner indoor air

  • Reduced allergens and dust mites

  • Prevention of mold-related health issues

  • Improved overall home comfort
