Are You Seeing Condensation on Home Windows? What That Moisture Is Trying to Tell You

If you’ve noticed condensation on the windows of your greater Cincinnati home, there’s too much moisture in your indoor air. Why is that important? Because too much humidity can cause moisture damage to your home. What can cause this sort of problem and what can you do to resolve it?

What Causes Condensation on the Windows?

Condensation develops due to the difference in temperature between indoor and outdoor air. When warm, moist indoor air bumps up against cooler window glass, that air cools. Warm air can hold more moisture than cooler air, so that cooling makes it release some of its moisture, resulting in window fog or larger droplets of water on the glass.

How can condensation on the windows cause damage? The moisture that collects on the glass typically drips down the window, wetting the window frames. From there it can leach into walls, rotting wood and other materials and promoting the growth of mold and mildew. Additionally, the excessively humid indoor air that causes window condensation can cause moisture damage throughout the house, condensing on other surfaces to damage things like wood floors, carpets and furnishings.

Correcting the Problem

Preventing condensation on the windows and other moisture damage in your home is all about keeping indoor humidity below 50 percent. Among the most common causes of humidity above that level is poor ventilation, especially in bathrooms, kitchens and laundry rooms, so have your ventilation system checked by a professional.

An unbalanced or improperly sized HVAC system can also cause overly moist air. Sealing any air leaks in your home’s exterior can help keep moisture out, as can replacing older, single pane windows with more efficient double-pane ones.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
