In the beginning, your windows might have been working great when you first installed them. But think about it. When your home appliances fail, you’ll replace them with new ones, right? The same logic should apply to windows, but unfortunately, some people let the problems grow too big.

Over time, windows start to wear out. There’s a seal between the glass and its frame, which will become loose eventually. There are many factors that make the fast transition between a tight seal and a worn-out one. Foundation settlement and temperature fluctuations are some of the more common causes.

Windows made from aluminum and wood are at the highest risk of allowing too much moisture to enter the house. Usually, the moisture enters the window sill first as it’s typically made out of wood. In this scenario, the water will seep deeper into the window’s structure, raising the humidity levels.

And if the windows haven’t been cleaned properly for a while, there’s going to be enough dirt and grime around to accompany the higher humidity. Dirt, together with humidity creates a hotbed for mold growth.

How will replacing the windows help to alleviate moisture and mold issues?

Buying and installing new windows is an effective step towards combating the mold growth. Your old windows shouldn’t be replaced by the same design and technology.

What might be other contributors to mold growth?

It’s always useful to think through what other risky areas in your home could be contributing to mold growth. Window glass replacement wouldn’t make a difference if there are other areas that make the mold growth easier.

Check and find out if there are any water leaks from your house’s foundation, plumbing, and roof. Also, make sure that your ventilation system works as it should. Before replacing the windows, make sure you get these other issues sorted out. Otherwise, you’ll change the windows, but the mold growth won’t subside.

How can I lower mold risk even more after window replacement?

Lower mold risk after window replacement

While window replacement is a great way to significantly decrease the mold development risk, there are still other factors involved if you look at the big picture. Look to see if increasing the temperature of the window glasses and frames will help with the moisture containment.

When the temperatures outside are lower compared to inside the house and you use blinds or draperies, then there’s a higher chance of condensation forming. Remove the barriers to the flowing air and raise the window structures’ temperature by putting a heater in a strategic position. This way you’ll effectively combat the condensation that could start creating a mold problem on the affected surfaces.

High humidity might be good for your airways when you’re sick, but it’s definitely not going to help you avoid mold growth in your home. Use air dehumidification machines to get the moisture in your house under control and decrease moisture in windows.

This equipment doesn’t have to be very expensive. You are able to get inexpensive dehumidifiers for a few hundred dollars online. And if you still get some condensation on the windows, remember to wipe it off every morning. Just leaving it there definitely invites mold into your home, in turn causing moldy windows.
