Why is there Moisture Inside my Windows?

Why is there Moisture Inside my Windows?

When you look out through your windows on a clear spring day, what do you hope to see? You’re probably imagining a landscape of healthy green grass, the sight of children playing, or even a glimpse of woodland creatures. That view can be less than perfect if it’s obstructed by unsightly water condensation that occurs on the inside of your windows. If inside condensation has become a fact of life with your windows, you may be resigned to simply deal with it.

However, overlooking window moisture can potentially allow more serious problems to arise that could cause serious damage to your home over time. In this post, our home exterior contractors at Powers Premier Contracting will talk about the causes of moisture on windows and what window condensation means for your home.

The Cause of Condensation

We’ve all seen condensation form at some point during the summer on a drinking glass. When the hot summer air comes into contact with the cooler surface of the glass that contains your beverage, this causes the water vapor to naturally condense. This results in droplets of water deposited on the cooler surface.

Condensation is especially common during the summertime or any time the humidity is high. If it forms between panes of glass on a window, it can’t be wiped or cleaned, creating an unsightly view. Even more concerning, the formation of moisture inside your windows indicates that your windows are no longer performing as they need to in order to provide good insulation.

The Problem With Condensation

In addition to obstructing your view, window condensation between your panes can lead to more serious problems for homeowners. Even a small amount of moisture over time can add up to significant damage around your windows. Water collecting around your windows can cause the drywall to become damaged and eventually penetrate the wood underneath it. Wood and water are a bad mix in terms of home components.

When moisture comes into contact with wood, it eventually causes the wood to rot or warp and allows mold to take up residences. Less toxic mold can create allergies and health problems for family members, and toxic mold can lead to devastating and even life-threatening neurological damage.

Sources of Humidity

As home exterior contractors based in Minnetonka, humidity is something we’re all accustomed to at Powers Premier Contracting. But weather-related humidity isn’t the only reason humidity can occur. There are also a number of humidity sources located inside your home.

Every time you do a load of laundry, wash the dishes, or run a bath, the humidity levels in your home can rise, which is why bathrooms and laundry rooms can have moisture damage. Humidity can also escape from inside of lumber and other natural building materials under some circumstances. If your windows are performing as they were intended too, however, these minor sources of humidity should not ordinarily be a problem.

Identifying Window Condensation

If you haven’t noticed condensation on your windows, it’s still a good idea to check around your home for signs of moisture on the inside of window panes. Identifying window condensation early could save you the trouble of having damage inside your home later on.

If your evaluation determines that there is window condensation, determine if it’s on the inside or outside of your window. Moisture on the outside of your windows is natural and nothing to be concerned about. Water collecting anywhere on the inside of your windows or inside the window panes is a red flag that your windows most likely need to be replaced.

Causes of Window Failure

One of the most common reasons for window condensation is simply the natural aging process. As windows get older, they will eventually begin to lose their insulating properties. Frequently, the caulk that helps to form the seals on older windows will begin to degrade and weaken, causing the seal on the window to begin to fail.

Even newer windows can experience seal failure if they’re not manufactured to high-performance specifications. Repairing the caulk is usually a temporary solution that doesn’t repair the underlying structural problems caused by the original seal weakening. Once the seals have initially weakened, the insulation qualities of the window begin to degrade as gas leaks out.

These are a few signs your windows are not insulating your home well:

●        High heating and cooling costs

●        Uneven temperatures inside your home

●        Drafts

●        Cold spots

Replacing Your Windows

Removing your poorly sealed windows and replacing them with newer ones is your best bet to restore insulation once window condensation has been identified. This removes the source of the condensation, giving you a fresh start and windows that will last for many years and backed by a warranty.
