I contacted Joshua B. Kardon, PhD, SE, F.ASCE, on the advice of a friend who is an architect after…read morewe won the bidding war (for $869K) on a 1924 Craftsman home in San Leandro in 2019. It had several issues, especially a problematic (cracked) original foundation. When Joshua Kardon informed us that we might have to spend a considerable portion of the above purchase price to properly fix up the house, make it earthquake-safe, and bring it up to current codes, we decided to pass on this lovely house. (He told us that replacing the cracked original foundation and raising the basement ceiling from 75 inches height to 96 inches on the 1400-square-foot home - all by itself - might cost $200-$300,000 and take many months. The home had other issues, too.) We later purchased a smaller 1954 ranch-style home in almost-as-built condition and called Joshua Kardon again for a consultation about seismic strengthening. He designed the almost-finished project that spans the front of our home and protects it against earthquakes. Joshua Kardon selected a "SkinnyBrace" by Thor Matteson, SE, of Quake Bracing LLC as the most cost-effective way to anchor our garage and the front of the house using attic collectors and garage shear walls. Nieto Valle Construction of Hayward has executed his designs and will soon finish the garage drywall and attic insulation. Joshua B. Kardon, SE, has always insisted on designing and implementing the best possible seismic strengthening solution for us and his solution is now in place. His attention to detail and insistence on doing things "the right way" are highly reassuring and have produced great results. Josh is also very personable, patient in educating us as to why certain design strategies work better, and has a great sense of humor. I would recommend Joshua B. Kardon + Co., Structural Engineers, in a heartbeat to anyone considering seismic strengthening or any other projects requiring the services of an experienced, thorough, detail-oriented, and friendly structural engineer.

They didn't answer the bulk of my questions, and they ended stating they don't have the bandwidth to take on my project.

I cannot say enough good things about Kent! He has helped us with the most important purchases…read morewe've made and with one of the most important things for our family (safety). While on the market for a house, our realtor contacted Kent for several verbal inspections. On one property that we were interested in making a bid on, we weren't sure if we needed a structural inspection because the house appeared well maintained and the lot was very flat. However, Kent came and told us this house would likely fall apart in a big earthquake, because it appeared never to have had any seismic retrofits since it was built 100 years ago. Bringing it up to current safety standards would likely be a huge project costing around $400k. We avoided a real lemon! Before making an offer on our current house, Kent also came. This house was in bad shape with a lot of deferred maintenance and borderline in a yellow zone on the Kropp map. However, Kent told us that the foundation looked good, seismic retrofits had been done probably in the last 20 years (so no further work was needed), and it was probably on bedrock. Sure enough, when we were replacing sewer laterals, the crew confirmed his evaluation (it was very difficult to dig and they had to drill a lot). At the same visit, we mentioned that we were going to see another house that just listed, which was more move-in ready. Kent advised us (free of charge!) that he already inspected that house and to avoid it completely. It was in a landslide zone and had already encroached into the neighbor's lot! That saved us a lot of time! Recently, I contacted Kent to evaluate our detached garage for seismic retrofitting, which to our knowledge had never been retrofitted since it was built about 100 years ago. Kent came for a site visit and wrote up a short report. He noticed that some of the concrete around the pillars looked newer and encouraged us to look through old permitting archives. When we did this and sent him the microfiche files from the early 1990's, he told us that indeed seismic retrofitting was done then and we didn't need to update it! Saved us probably around $30k!
