Condensation vs. Failed Seals: Why Your Cleveland Windows are "Sweating" This Winter

Many homeowners see fog on their glass and immediately worry about a leak, but at Progressive Windows & Doors, we know that "sweating" windows often tell two very different stories. Understanding whether you are dealing with simple surface moisture or a permanent structural failure is key to maintaining your home's comfort and efficiency during a harsh Ohio winter.

Identifying Interior Condensation vs. Failed Seals

Interior condensation occurs when warm, moist air hits a cold glass surface, while a failed seal manifests as persistent fogging trapped between the panes. We often see Cleveland homeowners mistake high indoor humidity for a broken window, but if you can wipe the moisture away with your finger, your seals are likely still intact.

Our Expert Winter Humidity Checklist

To keep your home healthy, Progressive Windows & Doors recommends maintaining indoor humidity levels between 30% and 35% during the freezing months. We suggest checking high-moisture areas like kitchens and basements frequently. Managing your home’s airflow and using dehumidifiers can often resolve surface "sweating" without needing a full window replacement right away.

The Advantage of Windsor Triple-Pane Glass

When simple humidity control isn't enough, we recommend upgrading to Windsor windows featuring Triple-Pane LoE glass technology. These advanced units keep the interior glass surface significantly warmer than standard glass. By reducing the temperature differential, Windsor windows effectively eliminate the "sweat" factor that plagues older, builder-grade windows in our local climate.
