Is Your Crawl Space Affecting Your Whole Home?

Your crawl space sends air straight into your living space. Watch for these signs that your crawl space needs help:

In Your Home:

  • High summer cooling bills
  • Cold floors in winter
  • Musty smells that won't go away
  • Uneven temperatures between rooms
  • Indoor allergies getting worse

In Your Crawl Space:

  • Damp or wet insulation
  • Rusty metal parts
  • Sagging plastic barriers
  • Standing water or wet spots
  • Moldy wood or beams

These aren't just annoyances. They're signs that your crawl space is working against you. Your home can't be truly comfortable or efficient until your crawl space is fixed right. 


I see these problems in Knoxville homes every day. Most homeowners don't know their high energy bills and comfort issues start under their feet. Let's find out what's really going on under your home.

The Science Behind Proper Crawl Space Encapsulation

Your house works like a chimney. Warm air rises, pulling air from your crawl space into your living areas. Scientists call this the "stack effect".


This means:

  • Up to 40% of your indoor air comes from below
  • Crawl space moisture rises into your home
  • Mold spores travel up through your floors
  • Cold winter air chills your rooms from below 
  • Summer humidity sneaks in through your foundation 


That's why proper encapsulation matters. It stops these problems at the source and turns your crawl space into a clean, dry foundation.

What Sets Our Encapsulation Apart

Most companies just lay down thin plastic and call it done. That's not encapsulation - it's a temporary cover-up. 


Our system is different:

  • We use vapor barriers that last decades, not years
  • Every seam gets sealed with special tape
  • Dehumidifiers match your space's exact needs
  • All corners and edges get proper attention
  • No gaps or loose edges left behind 


I personally check every installation. Your crawl space won't just look clean - it will stay clean and dry for years to come. Water finds every weakness. That's why we focus on complete protection, not quick fixes.
