Seismic Retrofit Experts Require Continuous Education

Bay Area Retrofit’s founder Howard Cook already had 10 years experience as a general contractor before he founded the company.  He combined this experience with his research skills from graduate school to become one of the nation’s top experts.  He has studied with the leading engineers in the country as well as designed thousands of retrofits over the past 25 years.  In addition, he is in regular contact with the most important research labs in the world.  Seismic retrofitting is not just his job, it is also his mission to save homes and lives.

He makes it a point to keep up on the latest research and is known to say “the more I learn, it seems like the less I know”.  He has developed important first name basis relationships with the best seismic retrofit engineers in the country.     This website is the result of those years of research and his desire to share his knowledge with the public.  If you see a subject that you wish researched and published please let him know. Bay Area Retrofit has also received excellent reviews from Angie’s list and YELP, in addition to recommendations from some of the finest engineers in the field.


Education is Number One

A Well-Trained Crew

Similarly,he passes his knowledge onto his employees.  In this way, he tries to make them seismic retrofit experts as well.  Seismic retrofits often have unexpected challenges.  These challenges make understanding seismic retrofit engineering a must.

This work requires unique individuals.  They must be intelligent enough to grasp the engineering principles. At the same, time they must be OK with crawling under houses all day.  It takes time to train such people and we must pay them well. We know we must pay well and treat well  to make sure the job is done right.

We are innovators

Bay Area Retrofit developed the Flush Cut Method, and is the only company in the state who uses it.

Bay Area Retrofit is the only seismic retrofit contractor in the country that uses Mudsill Plates. This hardware increases bolt strength.
