Dehumidifiers - The Last Defense Against Excess Moisture

The first step to dehumidifying damp a basement is to keep water, moisture, and water vapor out!

Today’s new home builders and contractors are taking steps to do just that by installing vapor barriers under slabs, adding waterproof coatings and membranes to foundation walls, and installing exterior drains around the perimeter of every home they build.

To prevent moist air from reaching living spaces, a variety of strategies are used, including:

  • Perimeter footing and wall drains, such as CactusBoard
  • Tight-fitting lids on sump basins
  • Dehumidifiers and mechanical exhaust ventilators
  • Insulated perimeter walls
  • Seals around doors and hatchways
  • Insulated and sealed ducts and pipes
  • Encapsulation of crawlspaces
  • Conditioned air supply

Unfortunately, keeping moisture out of a basement or crawlspace is a bit like keeping moisture out of a hole in the ground. Water vapor is everywhere, and it wants to go wherever it’s drier than where it happens to be. Open a window or door in the winter or go outside during the summer and all that air that’s loaded with moisture will tumble right into your basement. Flashing leaks around vent stacks and flues, plumbing and groundwater leaks may also be culprits. Even aquariums (fish tanks), houseplants, and new construction materials can raise moisture levels.
