Water entering your basement due to drainage problems, flash floods, appliance failures or other reasons can cause severe damage to your home. Here’s what you can do to stop water from accumulating into your basement. Blocked gutters may cause roof water to pour directly into your home’s foundation, increasing the risk of basement flooding. Remove any debris, such as leaves or branches from the gutters and check the gutters for loose particles if you have asphalt roofing. Tighten any loose gutter straps and spout extensions. If there is gunk in the downspouts, clean them by pouring water into the downspouts with a garden hose.
