Keep Gutters Free of Debris The best way to prevent basement flooding is by keeping your gutters free of debris. Preventing water from leaving your premises is never helpful. Your gutters were put in for a reason and driving water away from the home is its No. 1 function. If leaves or branches get caught in your gutters, water could start to pile up and leak right around your foundation. The more water near the foundation, the more likely your basement is going to flood. Cleaning your gutters is easy and should be done every spring and fall. See our step-by-step guide for cleaning your gutters here.
Make Sure There are No Cracks in the Foundation Even if your home has no history of flood damage, it is vital that you seal cracks in the foundation walls and basement ﬂoors. I don’t need to explain that if there are holes in the foundation, water will get into the basement. There is no way around it.
Many sealing solutions are DIY projects, but some require professional installation. Start by removing any crumbling concrete and repair all cracks in the walls and floors. Use masonry caulk on cracks less than 1/8 inches wide. Caulk only costs about $10 per tube. Patch wider cracks with epoxy filler and a putty knife. Remember to patch the places where pipes and tie rods pass through the concrete. Drylok Fast Plug is effective for sealing cracks in masonry. For complex cracks or those subjected to movement, hire a professional, as DIY kits are less reliable for this level of damage.

Position Downspouts Away from FoundationYour gutters could be as clean as whistles, but if you don’t have proper downspouts directing all that water away from your foundation, basement flooding can occur. They need to be thick and long enough to handle large amounts of water. Especially in areas of heavy rainfall, downspouts of 3X4 inches are highly recommended. They should be placing the rain gathered from the gutters at least five feet away from the home. If your current downspouts are not meeting these basic guidelines, you should think about extending them, another simple DIY project
