How To Prevent Mold In Your Garage
Instead of tackling the mold, we need to tackle the moisture. To prevent standing water, rainwater, and flood water from entering the garage, you should install a garage door threshold seal. This will create a watertight barrier underneath the door and prevent excess moisture from entering.
Condensation is the second biggest damp problem that contributes to mold. This can be prevented by improving the air circulation by installing an air conditioning unit, or ventilation system. Maintaining a constant temperature that is above the dew point will also help prevent condensation. Therefore, insulating the garage door (walls and ceiling as well) will help maintain the temperature and prevent condensation.
If you invest in a quality weather seal, AC system and insulation, you can save yourself a small fortune in mold remediation costs.
