Get out in the rain and look at your gutters and see where they are coming out to. Make sure they are at least 18" from the foundation so water does not pool. You don't want standing water at the base of your house. This means you have poor drainage. You may need to address the need for a french drain or swale around your house.
A french drain is underground and catches the surface water as it seeps into the ground and usually redirects it into the street. The small ditch surrounds the house and is insulated with a geotextile fabric that filters the water though while keeping dirt out.
A swale can also redirect water. Resembling a moat, the swale is dug around the house in order to re-contour the lot and provide natural drainage without all the underground pipes.
