Contributing factors to excess moisture in your crawlspace:

• Poor ventilation through crawlspace.
• Poor drainage around your house.
• Not paying attention to water run-off.
• No gutters or water spouts leading the water away from the house.
• A leak in the irrigation system.
• Condensation from the HVAC unit not piped to the outside.
• HVAC ducts not properly insulated.

Houses most prone to moisture problems:

• Non-sufficient crawlspace ventilation.
• Flat property with poor natural drainage.
• Soil level around the house above crawlspace.
• Dense shrubs blocking any natural ventilation.
• Large homes with extended foot prints.
• Large sections without vents, such as garages, decks, porches, and additions.

Inside your home look for:

• Distortions in your wood floors.
• Notes from your termite inspectors that you have a moisture problem.
• Excess amount of mildew in your house.
• High energy bills for your air conditioning system in the summer.

Inside your crawlspace look for:

• Stale and musty odors.
• Moist and wet insulation which is beginning to fall down.
• Mildew covering the wood structure, or even worse the growth of fungi on the surface.
• A wood surface which feels "soft" and can easily be penetrated with a sharp object.
• Water marks along the walls and under the duct works (HVAC).
• Any standing water after a heavy rain fall.
