I scheduled a consultation with Eugene from STEN Engineering to discuss two very different…read morestructural issues at my house, and I was extremely impressed. The first was figuring out how to realign a very complicated roofline so that rainwater would channel properly. The house has been built and added onto in stages over roughly 100 years, so every addition and alteration made the roofline more complicated and less cohesive. I had literally spent hours sitting on the roof trying to figure out a workable solution. Eugene looked at the situation, thought it through for about 10 minutes, and sketched out an option that simply would never have occurred to me. It was practical, elegant, and made immediate sense. The consultation was some of the best $400 I've spent. The second issue was understanding how well the house is braced for earthquakes and how the existing foundation works structurally. Again, Eugene combined a strong engineering mind with real-world practical experience and explained everything in a way that I could actually understand. I almost never take the time to write reviews, but I was impressed enough that here I am writing one. Eugene is smart, thoughtful, practical, and very good at explaining complicated structural issues in plain English. I would absolutely call him again.

This company is the absolute best! They took on a job at my house that over two dozen other…read morecontractors had looked at and could not figure out. My garage would flood when it rained heavily. The water was seeping/bubbling up through the concrete floor. Unfortunately,I spent a total of 20K on two other contractors before hiring Alpha. The work done by the first two contractors failed completely. When Damien from Alpha Structural initially came over, I knew I was in good hands right away. He is extremely knowledgeable, experienced, and professional. I would say the same about Brian and Nadir, who were the leads on my job. Brian especially, went above and beyond. Anytime I reached out to him he responded immediately, and was on site whenever I needed him. My garage was a nightmare scenario. I contacted just about every contractor who works on this kind of thing, from LA to San Diego. Not one of them could figure it out. Not one. This went on for 2 years. Alpha Structural took on a very tough job, and did what no other company could. They completely solved my garage flooding problem with a very strategic and comprehensive plan. Do yourself a favor and use this company! Don't waste time with others. Alpha Structural won't let you down.
