Seismic Safety really is the most-respected and most-reliable Earthquake retrofit Company in Pasadena and Los Angeles ( Southern California ). We have been around the longest, more than 50 years. Seismic Safety has seen virtually every type of residential structural issue, serving 20,000 properties just since 1965. We make homes safer in the case of Earthquakes, we also repair and install foundations (an integral part of the structure), and mitigate slope and drainage issues on your property. Because the majority of this type of special construction work takes place beneath a home, many home owners come to us as victims of unscrupulous contractors, to fix or check the work of other so-called Earthquake Retrofit “experts”. In 57 years, we’ve never heard of any customer using another company to “fix” our work.
