Earthquake Retrofitting

Secure your home to its foundation and protect it from earthquake damage with expert house bolting solutions built for safety and long-term stability.

Overview

House Bolting (Seismic Retrofit) Solutions

House bolting is one of the most important seismic retrofit upgrades for homes in earthquake-prone areas like California. Many older homes are not properly secured to their foundations, which means they can shift, slide, or even collapse during an earthquake. In fact, one of the most common types of earthquake damage occurs when buildings move off their foundation due to weak or missing connections.

Signs Your Home May Need House Bolting

Many homes—especially older ones—lack proper foundation connections. Identifying these risk factors early can help prevent serious damage during seismic events.

  • Visible Gaps Between Structure and Foundation - Separation between the frame and foundation can indicate weak connections.
  • Cripple Walls Present - Short walls between the foundation and floor may require reinforcement.
  • Previous Foundation Movement - Shifting or settling may signal inadequate structural anchoring.
