I received quotes from a couple of companies, and while these guys weren't the cheapest, they were definitely the most knowledgeable and took the time to clearly explain how the repairs would be done. They completed the job in just two days and repaired two addional piers, and everything went smoothly. I do have a slight squeeze in one area of the floor in my raised home, and I'm currently waiting for them to come back and take a look at it. I know pier repair is not much complicated but their crew was professional and their price was reasonable. I would highly recommend these folks.

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.

We had a major renovation in my condominium complex in Hermosa Beach In 2024/25. We were undergoing…read morea $3 million renovation when it was discovered that we had serious structural issues in the rear portion of our building. Our contractor recommended KCE/Matrix engineering company with whom he had lengthy experience. This countermanded the advice of our architect, who wanted to choose his own architect named YT Engineering in Palos Verdes. It turned out that YT engineering didn't fully understand the issue, & proposed that we'd have to go through a seismic retrofit process in order to secure a permit. We decided to call in KCE/Matrix engineering and they provided a rather simple process to solve the problem and not over complicate the issue. Not only did it solve the specific structural engineering issue we encountered, but additionally, KCE/matrix engineering calculations, and felt that we might be able to solve some other seismic issues at a minimal cost based upon their findings. Their extra work saved us untold amounts of money, complications, time and future frustrations!!! This Isn't an exaggeration, it's a fact! As impressed as I was with the work that they did, it was backed up by the tone, the conversations and the professionalism with which this organization operated. I give particular credit to David Paiva at KCE/Matrix engineering: he was a pleasure to deal with, he was always calm, measured and followed through with his promises. Everything I asked, for within reason he provided without any problems or headaches. David Paiva and KCE/Matrix engineering were a pleasure to work with.

But now I'm very happy that Sam decided to take on the job and develop the structural calculations and drawings for removing a load bearing and shear wall at my Condo. The Project started in September 2025 with initial submittal of permit application package to the City. It went into construction about four (4) weeks ago and was successfully completed today (5/8). During the process, we developed trust for each other. I contacted Sam numerous times for questions, problems and consultations and he was always responsive. He and my architect friend worked together to develop the initial design but had to modify it to overcome a major obstacle that came up during the construction. He came over for construction observations and gave instructions to the contractor how to strap the beams together for maintaining structural integrity of loading and shearing. His fees were much lower than another builder whom I also got a bid from, and his approach to things was much simpler and yet conservative to that from the other firm. I told Sam, whether it is good or bad, I don't usually do reviews for others. But for him, I will do one. I'm thankful to have a great team of Sam (the engineer), my architect friend, and excellent construction crew to help me complete this project.
