    Foreman Derek Price led the Jamison team through the rigourous repair. The well area was very small and with the water main running through the middle of it made it even tougher. First they had to seal up a cracks in the foundation of the well area than apply the encapsulation system . After that the Grate Sump sump pump was installed to pump water out of the old water well area. We also replace the very old open Sump pump on their other side of the basement to reduce smells and odors .
