They’re easy to implement, but may not give you the desired aesthetic appeal that a condensation fix from a professional garage improvement company like Garage Living can provide.

Garage condensation: a simple explanation

Garage condensation results from moisture in the air. When that moisture makes contact with a cold surface, water droplets accumulate and lay the groundwork for future serious issues. Excess condensation and humidity levels in your garage can actually have a negative affect on the rest of your home, contributing to the growth of mold and mildew that pose health risks to you and your family.

Common sources of condensation

Our cold Canadian winters are especially problematic when it comes to condensation. Low winter temperatures, followed by the rising humidity of spring and early summer, can make your garage and home vulnerable to excess moisture. Rainwater and melting snow from cars parked in garages will also contribute to condensation.

Running appliances in a cold garage without proper ventilation will create excess moisture in the air.

Improper roof drainage causing leaks in your garage will lead to undesirable amounts of condensation.

7 ways to effectively reduce garage condensation

  1. garage heaterControl your garage’s temperature. Using an electric heater during the year’s colder months will keep the temperature and condensation under control. Avoid the use of heaters that create water vapour, such as propane heaters. Garage Living offers garage heaters that will work for you.
  2. Use a vapour barrier. Proper installation of a wall vapour barrier, or using insulation products with built-in vapour barrier, will reduce condensation. A vapour barrier can also be used to cover the floor, but avoid using it on ceilings. Doing this can trap water vapour inside your garage.
  3. Dry your vehicle off after parking it inside your garage. Condensation issues can be exacerbated by parked vehicles covered in moisture during snowy or rainy seasons. Simply taking a few minutes to dry off your vehicle with a towel will reduce the likelihood of excess moisture.
  4. Check your ventilation. Proper ventilation is essential to reducing condensation and helps maintain the balance between the air inside and outside of your home. Roof ventilation, such as commonly used turbine roof vents, also needs to be cleaned regularly to allow for efficient airflow.
  5. Check your drainage. Proper floor drainage and rooftop drainage that prevents leaks are important to keeping condensation in your garage at bay. Ensure that floor drain covers aren’t obstructed and that eavestroughs and downspouts are kept free of debris.
  6. Apply a floor coating. A garage floor coating will significantly lower condensation levels and also protect it against damage from wear. Many coatings contain granules that prevent slipping, which makes them an ideal choice for wet environments. Garage Living’s Polyaspartic Floortex™ Coating system is the highest quality cement floor coating on the market and a perfect remedy for your garage flooring problems.
