Seattle Seismic is a seismic retrofitting contractor based in Seattle, WA, focused on strengthening commercial, industrial, and multi-family buildings in Washington and Oregon.

We provide property owners and managers with comprehensive, end-to-end seismic retrofit solutions. Our services span the full lifecycle of a project, from initial assessment and engineering through permitting and construction, delivering a streamlined, single-source approach from start to finish.

The Cascadia Subduction Zone along with other fault lines threaten large areas of the northwest. Many buildings across the region, especially those built before modern codes, are missing critical structural connections that help prevent failure during seismic events. Our work is designed to reduce that risk.

We specialize in:
- Seismic Retrofits of Warehouse, Soft Story, and URM Buildings
- Seismic Assessment and Engineering
- Warehouse Column Replacement
- Epoxy and Concrete Crack Repair
- Seismic Gas Shutoffs Valves 

The goal is to make your building more resilient during an earthquake, protecting tenants and your investment.

Reach out for your seismic evaluation to help you understand your building, your risk, and your options.
