Condensation on windows,
We bought new double-pane windows 5 years ago. We have our house insulated in the attic and walls.We also had a air flow breather added to our furnance. This week the windows are still sweating.What do you suggest we should do next?

| Merica Petrella- Moisture on windows indicates a lack of fresh air in the home. A healthy home as an air change every four hours. Increasing the fresh air ventilation will resolve moisture on the windows when cold outside. Mechanical fan ventilation is the practical method and increases the cost of heating for the year only $50 per year. Homes need fresh air all year including summmer. I suggest introducing fresh air with our Ultra-Aire APD. This unit provide dehumidification of fresh air and the home during the high humidity times of the year plus fresh air ventilation all year. High humidity in a home causes the growth of mold/mildew and dust mites during the summer. This results in the accumulation of allergens, poor indoor air quality and sick people.

Where do you live? If earthern floor means exposed earth in the crawlspace or basement, the earth must be covered with a vapor retarder.This is plastic with gravel on to keep it tight to the earth and protect it when walking on it or a layer of concrete. This eliminates the source of humidity during the drier winter months. If the windows sweat after a proper vapor retarder is installed, improving the fresh air ventilation is required. This is accomplished by mechanically moving more dry outside fresh air through your home. It cold be a simple as a high quality bath fan with fresh air inlets to a more complex ventilating dehumidifier. In extreme cold climates and high ventilation rates, a heat recovery ventilator is cost effective.
During the summer months, a properly sized dehumidifier is required to maintain less than 60% relative humidity under the floor. Fresh air vents to the outside must be closed when wet outside. Maintaining <60% RH prevents mold growth. It usually is better keep the vents closed year around in most green grass climates. In dry climates open vents are OK.
Creaking floors are caused by fitting original flooring when wet or wood expansion after the floor is layed. When the floor dries and shrinks, it's loose and creaks. Removing excess moisture will not help the floor problem. Keeping the home and it's ajoining cavities dry and mold
free are more critical than a creaking floor. Thanks

I too have water on my windows. What is the best way to
measure the humidity level in my home. Also will running
the dehumidifier in my basement, were my hot forced air
furnace is, help the situation at all?

Fresh air ventilation is the solution to your problem.
Fifty-eighty cubic feet per minute of exhaust or make-up
air ventilation will remove excess moisture from your
home. Our dehumidifier is installed to bring in fresh air
winter and summer to control winter and summer moisture and
provide fresh air.
