Earthquakes are fact of life in the Bay Area and your house should be up to California standards.

Crisman Inc. specializes in upgrading your home with features that make it safer in the event of an earthquake.

In the first case, upgrading consists of strengthening the connections between the house and the foundation. In the second case the goal is to supplement any existing connections to the foundation and strengthen the sub-area supporting walls using plywood, rebar, concrete and other strong materials. The images below illustrate some of these upgrades
