Surface Water and Low Spots - Look at the yard surface areas directly next to your home. Sometimes this area settles down from loose original backfilled material.
Look at your overall yard contours. Sometimes, this is best done during a substantial rainstorm. See have water reacts and flows. Look for water headed toward your home or ponding near it.
Solutions - Add soil to low areas and create a gentle slope "away" from your foundation.
If you have large areas that are directing surface water toward your home, you will probably need a professional landscaper with equipment to correct your problems. Sometimes, a landscaper can create a swale or lower contoured area to direct surface water to run around and away from your home.
Plant Boxes or Retainer Walls - If your wet spots inside correlate to the same areas in which you have planter boxes or retainer walls on the outside, it is likely that they are holding water and causing the problem.
Solution - Your solution to this problem may be as simple as drilling drain holes near the bottom of your planters or outside retaining wall. Drain holes will allow the water to slowly drain out so it doesn't build up and create a problem.
If retainer walls are being pushed out by frost, your solution might be to re-build the walls with drain tile and put crushed stone behind them for drainage.
