Why Do My Windows Have Condensation?

Are you experiencing window condensation problems? Although it’s normal for windows to fog up a little in the winter if you’re doing a few loads of laundry and the moisture levels inside your house are a bit higher than usual, a lot of condensation inside the window isn’t normal.

A too tightly sealed home can cause excess window condensation, but this isn’t always the case. Your windows may be sweating for a few different reasons related to the actual window:

  • Poor insulation
  • Improper or poor installation
  • Broken parts

Reasons for Window Condensation Problems

The excess condensation could be the result of any of the reasons mentioned above.

Poor Insulation

Condensation develops when warm, moist air meets a cold surface—like the glass of a poorly insulated window. Poorly insulated windows aren’t energy-efficient and don’t provide that extra layer of protection against the weather. Windows with high insulating values are less likely to experience condensation problems. Double- and triple-pane windows are energy-efficient and well insulated, especially models with a gas (usually argon or krypton) between the panes.

Improper Installation

If your window wasn’t installed right the first time—and you may not know or be able to tell until you start experiencing a bunch of problems—this could cause issues like condensation buildup. Your best bet would be to have a local window company come look at your windows and determine if you need to repair or fully replace them.

Broken Parts

If your window has lost its tight seal—and as windows age, this can happen, especially if you don’t keep up with proper maintenance and cleaning—condensation can build up on the glass. You may even see mold and mildew developing. Old, drafty windows need to be either repaired or replaced (depending on the severity of the problem) in a timely manner. If they aren’t, the problem can become worse and end up costing you even more money!
