Our Mission

Founded in 1954, Seismic Safety/ Ed Sylvis Construction is widely recognized as the premier Southland resource for residential earthquake reinforcement. We have a proven track record and work hand in glove with building authorities, structural engineering firms, seismologists, geologists, earthquake insurance underwriters, home inspection associations, and the best realty firms.
Our seismic retrofit projects include the U.S. Geological Survey Offices and the Southern California Earthquake Center at Caltech as well as local area homes in every price range.
Both the USGS and the Earthquake Center rely on us.
You can too.

Our Process

We never do estimates - they tend to either falsely encourage or falsely discourage home owners. We do however provide actual quotes for work that is actually needed. Our quotes are based on an actual "eyes on" an accurate exploration of an individual property. You can rely on our quotes. Our modest fees for inspection & written reports, including cost quotes for individual properties are refundable. Call us 9-3 for more information 626-791-2300

"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."

"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."

"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."
