#1. An Interior Water Leak

This may seem like a no-brainer, but you should always check for inside leaks first when trying to identify the cause of moisture in your basement. 

A water leak can come from numerous places: a shower, a sink, a toilet, a washing machine, a dishwasher, a bad pipe, just to name a few. You can even hire an expert for caulking and sealing services via https://mcgillbrothers.com/.

Sometimes, if the moisture in your basement is located on the ceiling or walls beneath a bathroom or kitchen, an interior water leak is to blame. Find where the moisture is located and determine if something in that area is leaking.

How to Fix It: An interior leak is typically one of the easiest problems to solve. Simply repair the leak (or have a plumber take care of it for you) and with any luck, that was the cause of the moisture, and it will be gone for good.

#2. Ineffective Grading

Rain or groundwater often makes its way into basements due to poor grading. The ground around your foundation should slope away from the house, not towards it. If draining in the wrong direction, water will accumulate against your foundation and eventually make its way inside. 

This often happens when fill dirt around your foundation isn’t properly compacted. As the dirt settles, the slope changes and water flows toward your house rather than away from it.

How to Fix It: Build up the dirt around your foundation, creating a slope aiming away from the house. This should be a minimum of one inch per foot, for at least 6 feet.
