What does a seismic retrofit include?



Consistent with the City of Portland's prescriptive path for Residential Seismic Strengthening, our seismic retrofits include automatic gas shutoff valves, foundation bolting and bracing, as well as water heater strapping. Learn more:




In the event of a major earthquake, your gas line could snap, spewing gas into your home and increasing the risk of an explosion. That’s why GreenSavers installs automatic gas shutoff valves. The valve connects to your gas meter and responds to seismic activity by stopping the flow of gas to your home.



Wood-frame houses generally fare well in earthquakes. But of Portland’s estimated 152,000 single-family homes, 70% were built before the first seismic code in 1978. That means they're probably not bolted to their foundations and could rattle off, leaving them uninhabitable.

GreenSavers adds bolts to improve the connections between your wood framing and concrete foundation. Bolts are driven through the sill or sill plate, which refers to the piece of wood that lies flat on top of your foundation. You may have no existing bolts, or the existing bolts may be either weakened or too far apart to provide enough resistance to withstand an earthquake.



Fresh water after a disaster may be as close as your water heater – if it is still standing. Water heaters can topple over during an earthquake causing broken water lines and flooding or broken gas lines and gas leaks. GreenSavers will securely anchor your water heater to wall studs or masonry.


GreenSavers takes care of the design, drawings, and permitting to make sure your project is up-to-code. With proper permitting, you can add earthquake insurance to your home insurance policy.
