Signs Your Crawl Space May Need Attention
Ground moisture, damaged vapor barriers, plumbing leaks and elevated humidity can contribute to poor crawl-space conditions.
Musty Odors
Persistent odors may indicate moisture or deteriorated materials beneath the home.
High Humidity
Elevated humidity may lead to condensation on pipes, ductwork or accessible surfaces.
Damaged Vapor Barrier
Torn or displaced material may leave exposed soil uncovered.
Sagging Insulation
Damaged or moisture-affected insulation may fall away from the floor system.
Visible Moisture
Standing water, damp soil or wet building materials should be evaluated.
Cold Floors

Condensation
Moisture on pipes or ducts can be a sign of elevated crawl-space humidity.
Mold or Mildew Concerns
