Step1

Keep your house well ventilated. Make sure that your home has good air flow. To accomplish this, make sure to install bath and kitchen fans and use portable fans during hot and humid days. If you have ceiling fans, use them to circulate the air in the room. Another way is to open the window to prevent moisture caused by poor air circulation. Check your air vents and ensure that they are not obstructed in any way.

Step2

Make sure that when you are cooking to use the air vent at all times and open the windows to help with air circulation. Follow the same tips when using the dishwasher. When doing the laundry, make sure to use the air vent to keep the moisture out.

Step3

Make sure that your room temperature is properly regulated. Condensation occurs when the relative humidity is too high for the temperature conditions, so you either need to increase the temperature of the surface of the window or lower the humidity in the room.

Step4

Firewood that is stored in the room can emit a lot of moisture so avoid storing them indoors. Live plants can also emit moisture that happens after watering which can be lessened when the plants are watered outside or at night to limit the condensation.

Step5

Check the windows and doors if there are any cracks or broken seals. Replace cracked windows and replace the damaged caulking or seals.

Step6

Check insulation on the attic and crawl space for any discoloration which can be signs of excessive moisture.

Step7

Avoid using humidifiers as much as possible and make sure that the air conditioning is drained outside away from the crawl space.

Tips & Warnings

When there is increased physical activity in the home, such as using the treadmill or any form of exercise, ensure that the windows are open and use a fan to lower the moisture caused by excessive body sweats.
