Basement window wells that are unprotected or poorly constructed can leak into a basement causing flooding and mold growth. Windows which are sub-level to the soil on the exterior need to be protected with window well guards or have drainage systems installed. Windows, like the one shown below, which are above grade but have cracking and are long past their life span, should be replaced. When water leaks into the basement behind drywall, you can replace the window to stop the water intrusion, but the interior walls will still need to be removed adding to the repair cost. It is wise to inspect the surrounding areas of your home every month or at least every other month to avoid such damages, and do whatever is needed to prevent an occurrence such as this one show here.
