One of the most frequent topics we deal with at this time of year is condensation on windows. We get lots of calls, and what we hear from people is that there is a very basic misunderstanding of why condensation forms in winter. (You can find several articles on our blog; here’s a representative one you can read – click here.) In this particular post, though, we’d like to address one of the side effects of letting that condensation just sit there. Moisture in a warm atmosphere can eventually lead to a very dangerous problem: mold.
Mold thrives on two common winter factors: moisture and heat. Mold development is a common problem in the winter months, mainly because people are indoors more and humidity builds up. Cooking, bathing, and even just breathing contribute to moisture in the air in a home. It can be even more problematic if you’ve replaced your windows and doors with more energy-efficient ones that prevent air leaks and cut down on drafts. While those characteristics can reduce your heating bills, one thing that results is a more air-tight home. And it’s exactly that lack of fresh air coming in that can foster both condensation and mold development. And as those mold spores grow, if you’ve got forced air heating, those spores will build up in your air ducts and get blown all through the house.
While mold can certainly damage any wood surfaces it develops on (such as window frames and trim), its affect on health is more concerning. Mold can trigger mild symptoms such as sneezing and watery eyes, but for some who have a mold allergy, it can be very dangerous. Symptoms from most respiratory allergies such as hay fever all but disappear in the winter months, but that’s not the case with mold allergies. In fact, they get worse as it gets cold.
To prevent that condensation from turning into mold, the first step is preventing condensation from developing. Reducing the humidity level in your home is the best way to do that. And then you need to stay vigilant for wherever condensation develops – not just on your windows but on any hard surface. Wipe it dry as soon as you spot it.
