Hi. The answer to this depends on how much your location will get water away from the house on its own. If you have a good negative slope away from the house for the first 6 feet or so, then that should help get it going the right way. If you are down at the bottom of a valley, then it might require a lot of digging for a french drain. Check posts below by Jay J on this subject. One thing that you might try are the clear plastic window well covers, available from home centers, to keep water from blowing directly into your wells during the heavy rains.
