Earthquake (or seismic) retrofitting involves stabilizing your house to help minimize any potential damage in the event of an earthquake.

It is not an all or nothing proposition. There are certain retrofitting basics that relate to most homes. These usually involve doing work in the accessible areas of the basement or crawlspace. More advanced projects often included strengthening the upper levels of your home, areas around openings such as garages or porches, or addressing other structural weaknesses. Basic retrofitting can often be done using standard details that Jim Gardner Construction- Structural Contractor can show you. These projects are often referred to as “voluntary sub structural strengthening “. We also work closely with a local structural engineer to provide low cost structural details so you can avoid costly engineering fees and over-designed projects in more complex retrofits.
