Minor leaks may not need the attention of a pro. "Often a few simple fixes will solve a moisture problem," says This Old House general contractor Tom Silva. His tips:
• Install diverters to send gutter water at least 10 feet from the foundation.
• Slope soil away from the foundation.
• Seal small cracks or gaps around pipes with concrete-patching compound.
• Fill larger cracks inside and out with hydraulic cement, which expands as it cures. A structural engineer should inspect any cracks that are wider than a pencil.
