What the work involves

After diagnosing a problem, an engineer can design the repair: number and spacing of piers, underpinning, wall anchors or bracing, and drainage changes. The design lets you get comparable bids and is often required for permits. The engineer may inspect during installation and issue a completion letter, which helps at resale.
