When Is Condensation a Concern?
Remember summertime? It’s that warm or even hot time of year when we lay back on our chaise lounge in the shade with a cold glass of our favorite beverage. It is so humid that the glass is sweating profusely and we find ourselves wiping our hands on a nearby napkin after every refreshing sip.
That wetness, my friend, is condensation. It occurs when the moisture in the air makes contact with the cold surface of the glass or bottle. This phenomenon is what also causes dew to form on your car or on the lawn on some nights.
On a cold glass of lemonade or on you car window shield condensation is usually not a problem, but just a nuisance. However, when it begins to appear on building surfaces within your home, it may be a problem and a sign that something is not quite right.
Here are some photos of condensation that indicate something is not quite right.
So, what’s happening? What can be done?

In summary, if there is an issue with condensation (sweating) inside a building, generally there is too much airborne moisture. On occasion, it may be due to a cold spot on a wall or ceiling due to missing or dislodged insulation. Most often, the amount of moisture in the air needs to be decreased. Airborne moisture may often be reduced by proper ventilation of the attic or living area or by reducing the amount of airborne moisture generated by human activities or equipment within the building.
Usually building codes, industry standards, and/or equipment owners’ manuals provide guidelines regarding the amount of ventilation needed or how to properly vent moisture generated by human activities or equipment. In unusual situations, the services of a mechanical engineer experienced in these matters may be necessary to determine a solution peculiar to the conditions. If you are unsure, get professional help.
