Condensation Solutions

Reducing the amount of moisture in the indoor air is the priority as it is often the least costly and most effective strategy.

Effective strategies to reduce moisture sources involve:

  • removing or reducing indoor moisture sources;
  • dealing with basement moisture problems;
  • prudent use of humidifiers; and
  • using a dehumidifier in the basement during fall, spring and summer.

Keeping surfaces warm is the next priority. This can be done by:

  • upgrading windows to energy-efficient ones with double or triple panes, low-e coated glass, argon gas between the panes, insulated spacer between the glass and insulated frames;
  • keeping drapes and blinds open during cold weather and overnight;
  • keeping walls and ceilings warm by adding insulation;
  • careful use of programmable setback thermostats so condensation-susceptible surfaces do not get too cold; and
  • providing sufficient heat to all indoor areas in the home and ensuring it flows over exterior walls, ceilings, windows and doors.

Providing adequate ventilation is also part of the overall strategy. This is done by:

  • installing ventilation equipment to achieve the right amount of indoor-outdoor air exchange;
  • providing good air distribution throughout the home and circulation within each room; and
  • using the ventilation systems as needed to maintain moisture level in an acceptable range.
Reduce condensation in the air in your home by controlling moisture sources, providing good ventilation, using dehumidifiers (when necessary) and keeping all surfaces at an equal temperature.
