Garage door window condensation is not a manufacturer defect, even if the windows are dual pane. The good news is that your garage door is doing what it's supposed to be doing, keeping the cooler air out. Unfortunately, if the ventilation in the garage is not maintained throughout the winter, condensation may appear.
Condensation on garage door windows is a characteristic of a warm, humid garage and a cooler garage door surface due to a colder exterior temperature. In fact, it's similar to the windows in your home. They too may form condensation because the temperature outside is cooler than the air inside of your home.
The Most Common Causes Of Condensation
- Difference in air temperature inside and outside of the garage
- A home with an attached garage may emit warm air into it
- Wet or snow-covered vehicles
- Moisture from an adjacent laundry area
- An old fridge or freezer that isn't climate controlled
- Restricted air flow due to clutter in the garage
Tips For Controlling Condensation
- Maintain proper garage ventilation
- Do not idle a vehicle inside of the garage
- Lower the garage air temperature during extreme cold weather conditions, for example, leave the garage door open a small amount or run a fan to circulate the air
- Dry off wet vehicles after parking in the garage
- Invest in a dehumidifier or heater
Replace Your Garage Door

Frequently Asked Questions
Does condensation mean my garage door windows are defective?
No. Condensation, even on dual-pane windows, is a normal reaction to warm, humid air meeting a cooler surface. It is not a manufacturer defect.
How can I quickly reduce condensation in my garage?
Improve ventilation by cracking the garage door slightly or running a fan, dry off wet vehicles, and address clutter that restricts airflow.
Should I be worried about condensation between the window panes?
Condensation between the panes, rather than on the surface, can indicate a failed window seal. This is different from surface condensation and may be a sign it's time for a replacement.
Can a dehumidifier help with garage window condensation?
Yes. A dehumidifier or small heater can help regulate humidity and temperature in an attached garage, reducing the conditions that cause condensation.
When should I consider replacing my garage door because of condensation?
If condensation is trapped between the window panes, the seals have failed or the moisture is affecting the door's finish and hardware, a residential garage door replacement may be worth considering.
