About this business

NW Seismic specializes in seismic retrofits, or in other words, attaching a house to its foundation. At NW Seismic, we engineer our retrofit designs for each specific house, rather than relying on a prescriptive path method of installing retrofit anchor plates every 4'. We also specialize in foundation repair/replacements and installing automatic gas shut-off valves. Have a finished basement? We handle finishes in-house.

When Tim came to analyze the particularities of our 100-year-old house, he explained why the simple recipe that most contractors use is not the best practice. He then clearly described the procedures for our situation, as well as the reasons behind them. When it turned out that our installa... read more

Had a terrific experience with NW Seismic. Really impressed by their team. After speaking with a different organization and not getting a great vibe, I reached out to NW Seismic.

They were able to come up with a plan to secure our old house without spending an exorbitant amount of money. Defin... read more
