How To Prevent Your Garage From Flooding

Your garage may be one of the most vulnerable buildings on your property. Because it is designed to accommodate your vehicles, its entryway is at ground level and very wide. These conditions make it susceptible to flooding, which can have serious consequences. Not only can your belongings sustain water damage but flooding also can weaken the structure of your garage and lead to the growth of mold and mildew. No property owner wants to deal with any of these issues, which is why you need to know how to prevent your garage from flooding. Fortunately, there are a number of steps you can take to stop garage flooding from becoming an issue at your home or business. Here are some of the most effective.


Your garage’s foundation can shift and settle ever so slightly over time, which can lead to the formation of tiny cracks. Even though the cracks may be almost imperceptible to the eye, they provide an entry point for water. If it freezes, it can widen the cracks and make them worse. Take a walk around your garage and look for any signs of cracking. A concrete sealant or fresh coat of waterproof paint may be all you need to prevent garage flooding if you have this problem.


When considering how to prevent garage flooding, don’t forget to inspect your gutters and downspouts. If they’re blocked, clogged or not draining properly, rainwater can pool around the base of your structure and infiltrate it. More effective drainage will carry rain and melting the snow away from the garage and keep it protected.

Inside your garage, you might choose to add flood vents that will allow floodwater to rapidly enter the building and to leave it just as quickly. Although the interior will get wet, the vents can prevent long-term damage by draining faster and keeping the water out of your business or house.


If the area around your garage is prone to flooding, you may want to dig a trench or place sandbags around it to keep out the floodwaters. The sandbags will expand when they become wet, providing additional protection.


If you’re wondering how to stop your garage from flooding, the best answer may be found at the bottom of your door. A gap between the garage door and the floor allows rain, snow and all kinds of unwanted guests into your structure. Installing a threshold seal from GaraDry will create a barrier that keeps your space dry, clean and climate-controlled.
