What causes high humidity in newly built homes

Controlling your humidity levels inside your newly built home may be difficult over the first year or two, but it gets better as the condensation on windows reduces as years pass by.

Moisture condensation occurs quite frequently during the first heating season of a newly built home. This happens regardless of your wood frame construction type. The condensation may come off like a fog on your windows and may even freeze on your glass. Moisture condensation most likely appears on windows instead of walls, as glass surfaces contain the lowest temperature compared to other interior surfaces of your home. As the warm, moist air gets in contact with your cooler glass, condensation will occur. You have to turn your HVAC system on for the moisture to dissipate. As the winter season comes and goes, one of the challenges new homeowners face is understanding the increased humidity levels inside their newly built homes. New homes usually have freshly poured concrete that requires time to cure properly. The wood products used to construct your home also expel moisture into your atmosphere, increasing the humidity levels indoors. Controlling your humidity levels inside your newly built home may be difficult over the first year or two, but it gets better as the condensation on windows reduces as years pass by. Moisture condensation may also accumulate in your new home after the first year due to everyday living. Today’s homes are built so tightly, making them more susceptible to retain moisture from bathing, cooking, heating with fossil fuels, drying clothes, and even breathing. Proper ventilation in a home will help maintain the correct moisture levels indoors, balancing safety and comfort. Excessive moisture in your new home could also be caused by the external conditions of your home, such as poor exterior grading, high winds during heavy rains, and a high water table.
