Eliminate the Problem

Moisture problems in existing basements are very common, but often are not understood or properly treated. In a basement that is seldom used and separate from the living spaces above, this may not present a great problem. However, most basements in Michigan are connected to the rest of the house through ductwork or other openings. In addition, basements are increasingly used as finished living and bedroom spaces. In these cases, moisture problems are not only annoying and uncomfortable, but can lead to significant health problems. Mold and mildew can grow in damp carpets and beneath wall coverings. Finishing a basement without first dealing with the moisture problems can result in making health conditions worse, and lead to significant damage as well. Basement water problems are solvable, but there is a cost to doing it right.

A problem that can damage your health and home

To correct basement moisture problems, it is necessary to understand where the water is coming from and what mechanisms permit it to enter the basement.


There are just three sources of moisture:

1. Liquid water from rain or ground-water.

2. Interior moisture sources such as humidifiers, unvented clothes dryers, bathrooms and cooking, as well as the moisture in concrete after construction.

3. Exterior humid air that enters the basement and condenses on cooler surfaces.


Moisture is transferred from the outside of the building to the basement interior by four mechanisms:

1. liquid water flow

2. capillary suction

3. vapor diffusion and

4. air movement.

Sometimes problems are traced to poor construction with cracking, settling foundations. In many cases, however, houses and basements can be structurally sound but are often not properly built to handle water drainage. Failure to slope the ground surface away from the foundation or lack of a good gutter and downspout system is common. Missing or non-functioning subsurface drainage systems are also found relatively frequently. These problems can all be addressed and corrected if a systematic approach is used.


Understanding the problem

  • Water trickling out of walls

  • Standing water on floor

  • Saturated base of concrete block wallS - a ring of dampness

  • Damp, humid air

  • Condensation on cold walls and floor in summer

  • Odor, mold and mildew

  • Deterioration of carpet or wood

  • Rot and decay of wood headers, joists, sill plates and columns

  • Staining and blistering of wall covering

  • Efflorescence, spalling of concrete or masonry
