Missing or Defective Gutters and Downspouts
The purpose of gutters and downspouts is to direct rainwater away from the foundation of your home. If those gutters and downspouts are missing, or not functioning properly, rainwater is often directed towards your foundation.
How to Fix It: Consider adding gutters if there are none already in place. A minimum of 1 downspout should be placed per every 50 ft. of the roof eave.
Extenders should be placed on all downspouts, dispersing water at least 4 ft. away from the foundation. Existing gutters should be cleaned regularly to ensure they are functioning properly.

Cracks in Your Foundation
If you have cracks in your foundation, you can be sure that water will find them and make its way into your basement. In fact, sometimes the water is even the cause of the cracks themselves.
If floor joists are not properly connected to the foundation walls, it can allow the walls to move, and in turn, cracks are formed. Water can actually cause cracks in the foundation as well due to poor drainage in the soil.
How To Fix It: Depending on the cause of the cracks, your solutions will vary. If hydrostatic pressure is the cause of the cracks, repairing your exterior drainage should help to solve the problem.
The cracks will still need to be repaired, but the cause should have been repaired. If structural problems caused the cracks, proper footing and connections (straps or anchor bolts) should be put into place to seal the gaps.
