About NW Seismic
Since 1992, NW Seismic has designed and implemented seismic retrofits for homes in the Portland area. The company assesses each home's architecture and environment, then uses earthquake retrofit science, including the Base Shear Formula, to inform its work. Its residential retrofits are intended to help keep a home securely attached to its foundation during an earthquake. NW Seismic offers free in-home consultations and estimates. The company is family-owned and focuses on preparing homes for seismic activity, including earthquakes along the Cascadia Subduction Zone and local faults. Retrofit costs vary with home size, construction type, and finishes; the website says most projects cost between $3,500 and $6,000.
