Dr. Robert Winter, Pasadena. "I have great confidence in Ed; he and his crew strengthened my stone foundations and retrofitted the bolting in such a way that it is now earthquake-resistant and still looks original."
Mr. Tim Eng, Pacific Palisades. "I found you on the internet ...your professionalism during the pre-contract inspection of my home made it easy to select you. Thank you for your honesty and the thorough job."
Cheryl Manning. "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."
Momita Sengupta, Venice. "I am writing to express my gratitude for the work completed on our house. This is our first home and a very important investment to us. Your crew has been incredibly polite, neat, and hard working. Ken Compton was extremely helpful and gracious ... I am glad we decided to go with Seismic Safety for our retrofitting work given the care and attention our house has received. I will be recommending your company to my friends and colleagues."
Mr. Brian Ofria. "My father is an engineer of some renown. He and I agree that Ed Sylvis saved the life of our wonderful home here in Woodland Hills. He did exactly as promised and a little more. We did our research on him before contract. Everyone said and promised us that we would be happy we chose him, and indeed we were."
