Seismic Retrofit Contractors In Oakland, San Francisco, and Berkeley

By Howard Cook, Founder and General Manager of Bay Area Retrofit


Residential Seismic Retrofit Contractors for the past 21 Years!

Bay Area Retrofit was founded in 1994 by general manager Howard Cook who became a seismic retrofit contractor after evaluating earthquake damaged homes first hand while employed by the Federal Emergency Management Agency.   He has intensively researched the subject first hand damage in the Los Angeles Northridge Earthquake and Loma Preieta San Francisco earthquake. During the past 21 years he has developed important relationships with the best seismic retrofit engineers in the country as well as those found at numerous seismic testing laboratories.

Over the years he has been very active in the field and has made many original contributions; both technical and eductional.

He took the FEMA sponsored course in seismic retrofitting 5 times and now teaches that course for the Association of Bay Area Governments.

Howard wrote an article for the Journal of Light Construction, a magazine targeting construction professionals, and was interviewed as a seismic retrofit expert on national and local TV.

As a consumer you should ask questions so that you can be sure you the person you hire knows what they are doing.   Our FAQ page answers most of those questions.

A Well-Trained Crew

Howard holds classes to make sure our employees understand the engineering behind retrofitting and how to apply it.  Seismic retrofits often have unexpected challenges and training in engineering is vital.

It takes a unique individual to be smart enough to grasp the engineering principles and at the same time be OK with crawling under houses all day which is what seismic retrofitters must do.

What do seismic retrofit contractors do?

Educating our Employees

We are innovators

Bay Area Retrofit developed the Flush Cut Method so we could do work that was based on the best science. This method creates seismic retrofits that are better and stronger.

In addition, Bay Area Retrofit is the only seismic retrofit contractor in the country that uses Mudsill Plates, a type of hardware made after the Northridge Earthquake.


Howard saw a great opportunity when he was able to bring in the Bay Area Retrofit’s Operations Manager, Jeff Bailey, as a partner in 2005.  Howard believed Jeff’s enthusiasm, 40+ years in construction,  and a degree in construction management  made him highly qualified for this important position.
