Jamison Basement Waterproofing replaced our sump pump and discharge lines. They provided options that we could choose from. The job was well done, and on time. They have an excellent team who can advise you on any issues and possible solutions. On the whole, our experience with Jamison was very positive.

Jamison Basement Waterproofing Project Manager Steven Custus went out to meet with the new homeowners. Steve recommended a full perimeter drainage system. The GrateDrain (Closed) drainage system will drain the water from below the basement floor to the GrateSump. The GrateSump with an 1/2hp pump can remove up to 3,400 gallons of water per hour from the basement. We installed 3 GrateSumps because of the high volume of water this home was taking on.

We also upgraded the homeowners sump pump to a half horsepower pump that can pump 3900 gallons of water per hour from the basement.

Project Manager Steve C went out and gave the homeowners a few options to keep the basement dry all the time , he even recommended starting with the Grate-Sump , sump pump and the wet area of the basement . The homeowners have the option of adding the perimeter drainage system at a later date . After few rains and the homeowners hearing the new Sump pump keeping the ground water below the slap during storms their problem is solved .
