Is your basement damp? Does it leak when it rains heavily? I see missing downspout extensions or very short extensions on about 40% of homes I inspect. An easy improvement you can make, with very little investment, is to move water away from your foundation wall. Add extensions to your downspouts that are at least 6 ft. in length and keep water away from your foundation walls. Keep your gutters clean and the extensions connected and enjoy a dryer basement.
