Not only are Sound Seismic's retrofit technicians trained on the technical level at the University of Washington they are also refined through field experience and continued education. In such an industry, on-the-job experience coupled with up-to-date product and procedure education is key to creating a quality earthquake retrofit.

The basics of retrofitting may seem pretty simple: bolt the house to the foundation and then apply shear panel to secure the pony walls of the house. As one might imagine "not all houses are created alike". Earthquake retrofit FAQ's

Retrofitting Works

Our highly-trained and experienced earthquake retrofit team is certified to help you protect your home against major structural damage from earthquakes.  We do not call our work "earthquake proofing", as there are simply no guarantees, but the methods and materials we use have been proven to be effective at minimizing earthquake damage.

Specific engineering requires specific retrofit carpentry. A saw, saw horses and lumber are always on the Retro Truck for just such needs. Pressure treated lumber with a sealant to protect it from moisture or insects.

 

The Retro Truck is fully stocked and ready to tackle any task when it rolls up on the job site.

All tools travel with the Retro Truck and many are powered by an on-board compressor.
