Warning Signs of Basement Water Damage


Musty Odors and Mold Growth

Musty odors are one of the most severe signs of water damage. When you smell musty, it's a sign of too much moisture. Mold growth is another standard indicator of water damage.


If you see white, powdery stuff on concrete or brick, it's called efflorescence. It's caused by water seeping through these materials and leaving salt behind. If you see it, it's a sign that water is getting into your basement.

Cracks in the Foundation

Cracks in your basement foundation walls and floors can develop over time due to water damage. Even a tiny break can allow water to seep in and cause significant damage.

Water Stains

If you see water stains on your walls, ceiling, or floors, it's a sure sign you've got a water problem. These stains can be of different colors and sizes, but they usually mean a consistent water leak.

Paint Peeling or Bubbling

Water seeping into your walls can cause paint to peel or bubble up on the inside of your walls. Please don't ignore this, because it's a sign of a problem with the moisture inside your walls.

Increased Humidity Levels

If you notice a rise in the humidity in your basement, it could indicate insufficient airflow and moisture. If you don't take care of it, you could get severe water damage.

It is essential to be aware of these warning signs and not allow them to become more serious problems. If you are concerned about basement water, please do not hesitate to contact us for an assessment.
