Window Condensation

Windows and doors are very important additions to any household. For starters, they allow natural light inside and properly ventilate homes.

Window Condensation

 

Without them, a house will never be efficient and liveable. For that very reason, most homeowners quickly assume that a small incident like window sweating is already a sign of leakage and that they need to call for a contractor immediately. In most cases, that is not what it is. Here are some reasons why your windows are sweating.

Window Condensation

A leakage on your replacement windows can be quite alarming; however, before replacing them,

make sure that it is not just window condensation. When warm moist air comes into contact with a cooler surface, moisture will form on the surface, and it is called window condensation. It is common and can happen in any household because moisture can come from anywhere since vapor pressure can force it through plaster, wood, brick and cement. Surprisingly, everyday living activities like cooking and showering can produce moisture.

What Should I do?

First of all, if you do not mind the look of a sweating window, then it’s best to leave it as it is. Window condensation is not a bad thing after all. It even proves that your windows have good tight seals and are energy-efficient.

However, if you prefer having a clear view all day round, what you should do is reduce the humidity in your home. Be sure to vent all your gas appliances like clothes dryers and exhaust fans outside. Moreover, your attic should have proper ventilation, and vapor barriers should be installed in your crawl space. Lastly, start running exhaust fans while doing daily activities that produce moisture.

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
