Garage Condensation & Moisture

Condensation in garages is a common issue that many homeowners overlook. Excess moisture in your garage can come from a variety of sources which are almost never construction related, and if ignored, it may cause structural damage, ruin stored belongings or create unhealthy conditions. Fortunately, there are several effective steps you can take to control condensation in your garage and protect your home.

What Causes Garage Condensation?

Condensation happens when moisture in the air comes into contact with a cold surface, forming water droplets. While this might seem minor, persistent condensation can cause:

• Damage to your garage’s walls

• Rust on vehicles, tools, and storage cabinets

• Mold and mildew growth, which can pose health risks

Moisture problems in garages can occur in all climates—whether from freezing winters followed by spring humidity, or in warmer regions with high humidity and occasional temperature swings.

Common sources of condensation include:

• Rainwater or melting snow brought in by parked cars

• Appliances like fridges or freezers running in unventilated garages

• Inadequate ventilation

• Improper garage heating

• Moisture and/or ground heat from floor drains

• Seasonal shifts in temperature and humidity

  
  

Ways to Reduce Garage Condensation

Garage condensation can typically be managed with some preventative measures and improvements.

1. Control the Garage Temperature

   Using a heater in winter helps stabilize temperatures and minimize condensation. Avoid propane heaters, which emit water vapor.

   
   

2. Dry Your Vehicle Before Parking

   During rainy or snowy seasons, take a few minutes to dry off your car before parking. This simple habit reduces the amount of water entering your garage.

   
   

3. Improve Ventilation

   Good ventilation balances indoor and outdoor air, preventing excess moisture buildup. Crack any windows, open garage door regularly, or install a ventilation fan.

   
   

4. Inspect Drainage

   Ensure your garage’s floor drains, drainage in front of garage door, and downspouts are clear of debris. Poor drainage can lead to leaks and increase condensation issues.

   
   

5. Apply a Epoxy Floor Coating

   An epoxy floor coating creates a durable, protective seal that lowers condensation levels.

   
   

6. Install a Dehumidifier

   A dehumidifier is a straightforward way to reduce moisture in the garage. Be sure to empty its water tank regularly, or connect it to a drainage hose.

   
   

7. Remove Old Appliances

   Old fridges or freezers in unheated garages are moisture culprits. Their drip pans collect water quickly, and condensation often forms on their exteriors when temperatures fluctuate.

   
   

8. Reduce Clutter

   Clutter reduces airflow, making it easier for condensation to form. Free up space by installing smart storage solutions.

   
   

Protect Your Garage and Home

Condensation in your garage may seem like a small problem, but over time it can lead to rust, structural damage, and mold growth. By understanding what causes condensation and following preventative steps you can safeguard both your garage and the valuable belongings inside it.
