"Seismic Safety bolted my house and adjusted the floors. I had no qualms about having them back in August of 2006 to build the foundation for my new addition. Because of their attention to detail and pride in a job well done, Seismic Safety is on my short list of contractors I recommend without hesitation. I look forward to putting these sentiments on Angies List."
