If you have never actually seen water leaking in your basement, you may believe that you do not have a problem and do not have to worry about water damage. However, you should periodically check for the following signs that you may have a hidden water problem inside the concrete walls of your otherwise dry basement.

1. Chalky Residue on Bare Concrete Walls

While inspecting your basement walls for signs of a hidden water problem, look at the bare surface of the concrete. See if you find a chalky residue that seems to glisten in the light, especially when you shine a flashlight on it.

If you do find any areas of this sparkling chalk-like residue, it is most likely efflorescence. This efflorescence is caused by water seeping into the concrete and pushing out such minerals as calcium or lime. Even if the water does not make its way to the interior surface of the wall, the deposits are pushed through the pores and gather on the concrete.

When you do find efflorescence, this is a sign that water is trying to make its way into your basement. If you do not have the issue taken care of by a professional, the concrete will eventually start to crumble, which would allow water to trickle directly inside. 

2. Flaky or Bubbling Paint on Painted Concrete Walls

If your basement is partially or fully finished, the walls may be painted, which would make it difficult to check for efflorescence without scraping off the paint. However, you can still tell whether or not water is seeping into the concrete walls by inspecting the condition of the paint.

When water gets underneath the paint, it will first start to bubble up as its adhesive properties are broken down by the moisture. These beginning bubbles may be difficult to see. However, shining a flashlight at an angle may cause subtle shadows that will alert you to their presence.

If you see painted areas that are starting to flake, this indicates that previous bubbled areas have deteriorated to the point that the water is removing the paint. A water damage restoration contractor can determine the true extent of the problem.

Along with the above signs, if you notice an ever-present musty odor in your basement, you most likely have a hidden water problem that is causing damage to your structures without you even knowing it. Contact a water damage restoration company to have them inspect your basement to see if you do have an issue so they can offer suggestions on how to fix the problem if necessary.
