In homes with basements and crawl spaces, we always need to be concerned with water flow from the roof. An overflowing gutter will dump water next to the foundation and create a water leak into the crawl space or basement. In homes with concrete slabs, the water next to the foundation can cause movement and cracking, which are bad things for a slab.
So, don’t let the gutters overflow. Trees can drop needles, seeds, and leaves that can make a real mess in the gutters. Establish a routine for cleaning the gutters that address the needs in your yard.
Also, make sure downspout extensions dump water away from the foundation. They should extend at least 3 feet and preferably 6 feet to an area where the water will naturally drain away from your home.
One of the best inspection techniques is to observe your home during a hard rain. Gutters should not overflow, and all surface water should be directed away from your home. Water pooled next to a foundation is almost always the cause of a water leak into a basement and can result in structural damage to walls and slabs. Maintenance is easy and simple – make it a priority.
