Down the stairs into a DRY basement!

Is your basement wet or do you have a flooded basement? Having a damp or flooded basement not only ruins a good mood, it can damage your home and belongings. Keeping a dry basement helps protect your home from flood and mold damage, and allows you to get the full use out of your basement's potential. There are several things you can do to help keep your basement dry.

Difficulty: Moderate
Instructions

Things You'll Need:

  • A stubbornly damp basement
  • Handyman skills
  1. Step 1

    Install gutters and downspouts. If you have gutters, make sure they are flowing freely and clean from debris. Downspouts can be installed that shoot water six to twelve feet from the perimeter of the home. Make sure the drainage flows away from the home.

  2. Step 2

    Install an automatic sump pump. Locate the dampest area in the basement for this installation. If you have a sump pump, you may consider lowering the pit. Ensure the pump is in good working order and the drainage from the pump flows clearly away from the home. This will clear standing basement water.

  3. Step 3

    Use a dehumidifier. Every damp basement will benefit from this upgrade. Let the drainage flow into the sump pump pit, so continuous emptying of a dehumidifier is not required. An alternative to the dehumidifier is ventilation. Simply opening the basement windows can help dry out the basement as well. This however, is a temporary solution.

  4. Step 4

    Seal the basement walls. There are many reputable concrete sealing products you can use to stop moisture from coming through the walls of your basement. There are products for the floor of the basement as well.

  5. Step 5

    Ensure your landscaping outside flows away from your home. If you have a steep grade leading up to your home, you may need to install a perimeter drain.

  6. Step 6

    Install a perimeter drain. I have included a link below explaining how this is done.

  7. Step 7

    If after all of this, you still have a wet, damp, or flooding basement, seek a professional. You can rest easy knowing you have tried everything!

Tips & Warnings
  • Consider adding backup power to your sump pump.
  • You may need two dehumidifiers on opposite sides of your basement.
  • Check your sump pump regularly to ensure it is still operational.
  • Basement waterproofing is a multi-pronged approach. Consider trying several of the methods above.
  • Landscaping draining and perimeter drainage can be complicated. Consider what you are capable of doing, and hire a professional if necessary.
