Basement waterproofing is about how water enters the basement, not the structural condition of the foundation itself. When you call, ask whether they're addressing interior drainage, exterior waterproofing or both, and whether sump pump installation is part of the job. If the foundation itself has shifted or cracked, the Foundation Repair page covers that separately. If the work involves digging around the exterior, make sure utilities are marked first; georgia811: com handles that for free. Georgia requires a residential contractor license for this type of work; run a free check at verify: sos: ga: gov before hiring.
