Crawlspace french drains and sump pumps are seldom required and are always a last resort and not a first home drainage solution plan. Groundwater that enters below grade into basements and crawlspaces must be collected and vented on the outside of the building with hand excavated french drains in order to stop the groundwater saturation and hydrostatic pressure that causes the leaking.

1. You find that you are getting water in your crawlspace or basement. This is one of the most conclusive home drainage signs, and many times it goes undetected if the water is in the crawlspace.
2. Your basement and exterior foundation walls show evidence of dark coloration and/or patching and skim coating. Sometimes the patching and skimcoating is done poorly, and if you tap on the inside or outside of the foundation wall in areas that show evidence of repair, it will sound hollow. This is because the mason was not experienced, and floated too much mix on at one time creating an air pocket behind the surface of the repair. Eventually this area will crack and fall away. No bond has been achieved.
