1.  LEAKY BASEMENT WINDOW WELLS:  When the window well is clogged, water will push up against the basement      windows until it breaks through the windows seal.

2.  FOUNDATION WALL CRACKS: Wall cracks could be a sign of an underlying structural problem.  They must be
     filled and sealed before water starts to seep in.

3.  EFFLORESCENCE: This is typically a white, flaky, and chalky substance that can be seen on the basement walls or
     floors. It is a sign that moisture is present.

4.  POROUS CONCRETE: Porous concrete has a unique appearance, and often falls apart in a honeycomb pattern.
     The problem is also sometimes referred to as spalled concrete. All terms refer to the same foundation problem.
      If left untreated for too long, moisture will begin to seep into the home. 

5. COVE SEEPAGE: The cove joint in the basement is found where the wall meets the floor. This area can be extremely
     vulnerable to ground water seepage. The soil around a foundation has constantly changing moisture levels. When
     it rains, it raises the water table. When there are dry spells, the water level goes down. However, the rising and
     falling of these moisture levels can put a significant amount of pressure on your foundation walls. Eventually, water
     pressure from the soil will break through the seal in your cove joint.  Once inside, the moisture can do a lot of harm
     to the basement environment. 

6. FLOOR DRAINS: Floor drains are often installed in the lowest lying area of a basement. The purpose of the drain is
     to prevent water from flooding this area of the home. If the basement leaks the water should be sent out through
     the drain before it is ever able to puddle up on the floor. However, these drains are not the best "waterproofing"
     system to have installed in a home, and they often times fall short when it comes to preventing serious moisture

7. WET FLOOR CRACKS: Floor cracks will eventually let water to seep into the home when the water table outside the
     foundation rises or falls. 

8. MOLD & MILDEW: Mold grows in wet and humid areas, such as in a basement with no waterproofing system, or in
     a basement or kitchen where there is a lot of moisture. 

9. SUMP PUMP: A sump pump's primary job is to keep buildings dry, so they're typically installed in the lowest part of
     a home's basement or crawl space, and are designed to discharge water away from sanitary sewers.  

10. LEAKING MORTAR JOINT:  Leaking mortar joints become weak over time and will start to let water leak into the

11. PIPE PENETRATION: The area where the pipe leaves the home through the wall may have a weak seal and will
     allow water seepage. 

12. GRADING PROBLEMS: Poor yard grading and drainage can cause water to pool up next to the foundation walls. 

13. TOP OF FOUNDATION: Water seeping in over the top of the foundation wall will leave a trail of water stains down
     the foundation wall.
