What Basement Problems Are You Seeing? (Click a Subject area)

Basement Problems
Top of foundation
Water seeping in over the foundation will often leave a trail of water stains down the foundation wall.
Grading problems
Poor yard grading and drainage can cause water to pool up next to your foundation walls.
Pipe penetration
The area where the pipe leaves the home through the wall could have a weak seal that lets water seep inside.
Leaking mortar joint
Mortar joints become weak over time and start to let water drip into the home and down the walls to the floor.
Sump pump
A sump pump can be used to control basement leaks and flooding. It pushes water out and away from the home.
Mold & mildew
Mold and mildew grow whenever moisture, excessive humidity, and organic materials are present inside of the basement environment.
Wet floor cracks
Floor cracks will eventually let water seep into the home when the water table outside the foundation rises or falls.
Floor drain
A floor drain often becomes clogged with dirt and debris, and it is also not uncommon for tree roots to grow them and obstruct the flow of water.
Cove seepage
A rising and falling water table outside of the home can cause water to be pushed through the cove joint (where the wall meets the floor).
Porous concrete
Concrete can become brittle and weak over time if it wasn't poured correctly, and this can make it very easy for water to get inside.
Efflorescence
This is typically a white, flaky, and chalky substance that can be seen on basement walls or floors. It is a sign that moisture is present.
Foundation wall cracks
Wall cracks could be an indication of an underlying structural problem. They must be filled and sealed before water starts to seep through them.
Leaky basement window wells
When the window well drain is clogged, water will push up against the basement windows until it breaks through the frame's seal.
