Humidity Control Ideas for a Garage

A garage is often built without the same climate controls as the rest of the house. The garage may not be attached to the house at all. Because of this, humidity can be a problem, causing mold, mildew or rust on the items stored in the garage. To prevent excess moisture in the garage, there are some methods you can use to help control it. Experiment with some of these ideas for humidity control and find an idea that is most practical for you.

Proper Ventilation

You can control excess humidity in the garage.

Moisture moves through the air very quickly and easily. One of the main reasons why moisture can build up in a garage is because of a lack of ventilation. During hot and humid weather, you should have a source of fresh air to keep air moving as much as possible. If the garage is closed off completely, open a window. If the garage doesn't have a window, you might want to put one in if humidity is a considerable problem.

Space Heaters

Space heaters are a good way to reduce humidity caused by condensation during cold weather. Even during warm and humid weather, the dry heat produced by a space heater can assist with dissipating humidity. Some electric devices are specifically designed to heat garages. These electric garage heaters are compact, lightweight heaters that produce clean heat without the need for fuel, and many have safety features that shut the heater down if temperatures get too hot.

Good Insulation

Adding insulation to your garage will help reduce humidity in the room drastically. Just as the rest of your home requires insulation to stabilize temperatures, keep climate-controlled air inside and outside air out, insulation in your garage will have the same effect. Simply reduce humidity through ventilation, heaters or other methods and allow quality insulation to help maintain the humidity levels.

Vapor Diffusion Retarder

You can install a vapor diffusion retarder in your garage to reduce the rate that moisture can permeate the room. These materials are also known as vapor barriers, although no material will completely stop the moisture from passing through. This is a process generally done in remodeling or building projects as the retarder is installed on the walls themselves to prevent excess moisture from penetrating the garage or other areas with concrete slab flooring. Vapor diffusion retarders include many different materials. Materials such as polyethylene sheets, stainless steel, aluminum and reinforced plastics are all effective vapor diffusion retarders.
