Water seeping into my basement due to a crack in foundation wall. House next door was demolished and they had water flooding from their service pipe, which apparently was not shut off. Restoration crew opened up the drywall and found the crack. Need to have the crack sealed and ensure no other immediate seepage in that section of the foundation. Cost efficiency is important for us. We are existing customers with our sump pump.
