Musty Odors and Damp Air
A lingering damp smell is a classic sign of poor ventilation. It can also affect indoor air quality.
Cracked or Warped Wooden Beams
Wood that swells, cracks, or bends suggests prolonged moisture exposure, which weakens structural integrity.
High Energy Bills
Leaky crawlspaces allow heat to escape in winter and bring in heat in summer, driving up utility costs.
Water Stains and Puddles
Visible water damage on the floor or walls points to leaks or inadequate drainage systems.
