Why Crawl Space Encapsulation Matters

Crawl spaces are one of the biggest sources of moisture, mold, and indoor air quality issues in Massachusetts homes. Without protection, damp crawl spaces can lead to:


  • Mold and mildew growth
  • Musty odors traveling into living spaces
  • Pest infestations
  • Foundation deterioration
  • Higher energy bills due to humidity
