Condensation in garage: causes and solutions

Exitech - Condensation in garage

Condensation is produced when excess moisture in the air comes into contact with a cold surface. Typically, you will notice drops of water or even frost. While condensation in the garage is a common problem, you should not ignore it as it may lead to more serious issues.

Read on and discover some of the causes and solutions of condensation in the garage.

Why is there condensation in my garage?

As mentioned above, condensation results from too much moisture in the air. When warmer air comes into contact with a colder surface, drops of water or frost may form. Garage doors are not airtight and have a surface area that is much larger than an entrance door. As such, it is not surprising that condensation would form in your garage. However, you should try to minimize humidity as it could lead to other issues. These may include accelerated rusting of cars, tools, and metal surfaces, damage to the foundation, and even the growth of mold and mildew.

Often, condensation results from changes in outside temperatures. After a cold winter, rising humidity levels in the spring can lead to condensation in the garage. Rain or snow on your car may cause more humidity. Additionally, running appliances in your garage can also cause condensation.

How can I reduce condensation in my garage?

There are a few things you can do to minimize condensation in the garage. However, for more complex issues, we recommend calling in the professionals.

  • Replace the weather stripping on your garage door. While garage doors are not airtight, ensuring you have proper weather stripping can help reduce garage condensation. Speak to an Exitech specialist to know what weather stripping solutions would work best for your garage door.
  • Heat your garage. For condensation to build up, floor and wall temperatures must be lower than the dew point. As such, a warm garage will help keep condensation in check. However, use electric heaters rather than propane ones, as propane heaters create water vapor.
  • Dry off your vehicle. A wet car, especially one covered with snow, will create more moisture in your garage. Try to dry it off after parking it in the garage.
  • Install a vapor barrier. Condensation in the garage can be reduced by installing vapor barriers or insulation with built-in vapor barriers. But, do not use a vapor barrier on the ceiling as it will just trap moisture in.
  • Coat your floor. A garage floor coating or epoxy coating can be applied to your concrete floor. It will dramatically reduce condensation.
  • Ensure good ventilation. Make sure there is enough air circulation in your garage. If you have a ventilation system, have it inspected regularly.
  • Inspect and unclog drains. Check indoor and outdoor drains regularly (especially in the spring) to remove debris and ensure there are no blockages.

While condensation in your garage is common, you should try to minimize it to avoid potential headaches. Furthermore, installing a high-efficiency garage door and proper weather stripping can help reduce condensation. For expert advice or to schedule an inspection, contact an Exitech expert today.
