Photo Album: Earthquake Retrofitting in Lakewood, WA

Album Description

Nobody wants to think about the potential "Big One" that might hit the Pacific Northwest in our lifetime, but for homeowners who want to ensure that they'll be able to recover after an earthquake, TerraFirma offers earthquake retrofitting.

With specially designed brackets, TerraFirma bolts your home to your foundation so that your home can qualify for earthquake insurance. It's difficult to find peace of mind when thinking about an impending earthquake, but the homeowner of this house in Lakewood, WA didn't want to take any chances, so they called TerraFirma once they realized they needed to retrofit their home to qualify for earthquake insurance.

Our System Design Specialist went out to the home and assessed that TerraFirma should install earthquake retrofitting brackets in both the basement and crawl space. With a plan set in place and the proper permits acquired, our production team went to work and retrofitted the home in three days.
