Condensation & Mold with your Windows & Doors

November 30, 2017

By David J. Wieland


    Window and glass door condensation is typically formed by natural occurrences. It is often times a warning sign that there is excessive moisture present. Whenever there is a build up of condensation, there is a higher risk of deterioration and the growth of mold. 


    A few Tips from us: 


  1. Keep in mind how mold is formed. Mold relies on high humidity from the interior of your home, coupled with low temperatures and condensation build up from the exterior of your window. Often times, fall and winter seasons present a higher risk of this. As we run our heaters inside the house, while it’s raining outdoors, we put our old windows at a high risk of build up.

  2. Mold is like an infectious virus. If not early detected, mold begins to grow and spread. First it may start within the window and then can spread into the wood foundation of your home, causing wood rot. Once your wood begins rotting, mildew often accompanies the problem. 


    We recommend ensuring that your windows are not being directly hit by your vents when running the heater this season. You become more susceptible to mold when your windows experience that high clash of temperatures imbalance. 


3.   There are products for your windows called an “air exchange device.” This helps create ventilation for your windows and ensures that moisture does not sit and build up in corner areas of your window.

4.   When you shower, we recommend running the exhaust fan in your bathroom. This will help balance the steam and humidity generated from your shower. 

5.   Buy a dehumidifier. This will also help establish a bit more of a balanced temperature in your home.

6.   Even while running your heater… consider keeping your fan going on a very slow speed (this will make sure that the air keeps circulating), or consider occasionally cracking a door or window to balance the temperatures around your window. 


    Some of these tips may be more practical than others (depending on how much of a winter wonderland you experience). We recommend that if your windows have possibly reached the “point of no return,” give us a call. We can talk to you about your next steps and provide you with a free in-home estimate!
