As the summer heat sets in, many homeowners find themselves dealing with a hidden adversary: black mold. While it’s often associated with damp, dark conditions, black mold can thrive in warm, humid environments, making summer a prime season for its growth. Let’s explore how condensation contributes to this issue and what you can do to prevent mold problems in your home. The Science of Condensation Condensation occurs when warm, humid air comes into contact with cooler surfaces, causing moisture to form. This is particularly common in the summer when the outside temperature is high, but the inside of your house may be cooler due to air conditioning. Common areas where condensation accumulates include: Windows : The temperature difference between the outside air and the glass can lead to moisture forming on the surface. Walls and Ceilings : Poorly insulated walls may cool down significantly, allowing condensation to form on them. Bathrooms and Kitchens : Areas that generate steam from s...

Winter can be especially harsh on a house's roof, and it’s almost never a good idea to simply wait for spring before addressing the issues that the presence of snow and ice on your roof can cause. Five of the main winter roof damage problems t hat homeowners should be aware of are listed below, along with some advice on how to best manage them. 1. Ice Dam Formation When warm air rises from your heated living spaces, it warms the shingles of your roof and the snow that covers it. This leads to snow melting and dripping down to the colder edges of the roof where it refreezes as ice. Once the ice grows thick enough, it backs up further snow-melt behind it, causing water to seep under the shingles, and eventually into your home through leakage points. Leaks are made the more likely when backed up water freezes and thaws, working its way into nooks and crannies and expanding them. The number one way to prevent an ice dam is by insulating and ventilating your attic, bu...

The dew point is the temperature at which moisture in the air will condense on a surface. It fluctuates with the outdoor temperature and relative humidity, which have an inverse relationship to each other.  Because cold air can hold less moisture than warm air, as the temperature falls the relative humidity rises and, when the temperature of a surface falls enough, it reaches the dew point—which is 100% relative humidity—and condensation forms.  The window glass of an air conditioned home will be cooler than the outdoor air on a warm morning and reaches the dew point temperature before other outdoor surfaces.  Occasionally, we get asked the question “Why do I have condensation when my windows are insulated?” An insulated window still has some heat/cold transmission, and the exterior glass surface will still be slightly cooler because of the chilled indoor air. Trying to determine why one window has condensate on it and a nearby one does not can get complicated due...
