I contacted Alpha Structural for concerns about the recent development of uneven flooring…read morethroughout the house, and today they sent out Ken Crown for a free inspection. After pointing out the areas of concern to him, Ken offered a couple non-serious possibilities for the phenomenon, and was able to assure me there was no threat to either the structural integrity of the house or the cement slab foundation - and pretty much bottom-lined it, saying there's really nothing to worry about. I really appreciated Ken's easy-going demeanor, and sensed zero interest in him trying to sell me a repair service that wasn't needed. Ken is just an honest guy offering his experienced opinion - in no doubt, putting yet another homeowners' unwarranted concerns to rest. Would be nice If all companies sent inspectors who operated the same way as Ken.

I arranged to meet with their representative to give me a bid on a property in Laguna Beach to…read morereplace a retaining wall and a cement pad that was part structural on a hillside overlooking the ocean. They gave me an early appointment so drive up early and from San Diego for the 8 AM appointment, about 9 AM they called and said he couldn't find a parking space. Which was odd because I was in front of the house and yes, parking is a challenge up there, but I didn't see the guy and if I had, I could've let him park in our driveway. We have a lot of vendors at the house so I usually wait out front when I know a new vendor is coming to assist with the parking. I tried to reschedule and they suggested two days which unfortunately I couldn't make work - when I called them back to reschedule for the following week, they said they weren't available for several weeks. I see that they're highly rated and I guess they have the option of treating a customer this way. I am tired of vendors who treat people like this. I was disappointed and will not be using them. I can only imagine what will happen when we schedule work at the house, no thanks.

We had a great experience working with Amgad and the engineering team at San Mina on our home…read moreremodel. The project was fairly complex--it included expanding our living space by building two bedrooms and a bathroom above the garage, as well as removing walls in the kitchen to create an open-concept layout downstairs that required new structural support. From start to finish, their team demonstrated a high level of professionalism and expertise. They took the time to fully understand our vision and translated it into a thoughtful, well-executed design. Their structural plans were clear and thorough, which made the construction process much smoother. Even when we encountered constraints due to city regulations, they worked closely with us to develop a revised design that both met approval requirements and aligned with our needs. We love our remodel thanks to Amgad and team!

We reached out to Amgad and within a few days he came out and was able to start the plan right away. It took him only 2 weeks for the plan! He also referred us to a trustworthy contractor that was able to execute the plan with no issues. From beginning to end, Amgad was very responsive. He would also work with our contractor to make sure our project went smoothly. We would definitely contact him again for any future project.

From start to finish, the level of professionalism, expertise, and attention to detail was truly outstanding. The engineer demonstrated a deep understanding of structural integrity while also respecting the design vision for the space. He carefully evaluated the existing structure and developed precise plans to safely support the load while allowing us to achieve the open, modern kitchen we wanted. His calculations and documentation were thorough and well-organized, which made the permitting and construction process much smoother. What impressed me most was his ability to balance technical precision with practical solutions. He communicated clearly, answered all questions patiently, and ensured the plans were easy for the contractor to follow. The result was a seamless transformation--our kitchen now feels bright, spacious, and beautifully integrated with the rest of the home. If you need an engineer for structural modifications, especially for projects involving load-bearing walls, I highly recommend his services. His expertise, reliability, and commitment to quality truly set him apart.

I had a roofer tell me that my entire roof support structure was in danger of failing and they had…read moretheir structural engineer come out. The estimate was astronomical and would take months to complete. I brought in Distinguished Structural Engineers to give me a second opinion. They give me a written analysis with lots of pictures pointing out some issues, but they gave us peace of mind that the structure was fundamentally sound and only needed attention in a few areas. We used one of their recommended roofers and spent a tiny fraction of the first roofer's estimate to correct the issues. I highly recommend Distinguished Structural Engineers for any work you're considering.

We laid out what we wanted and Fredy told us what we could and couldn't do. He told us he could have the plans done pretty quickly and we were happy with how it was going until.. We wanted to add a skylight and asked Fredy about it. He quickly said we couldn't and gave no real explanation why. So we did a little research, asked another engineer and found out it was possible. When we called to ask Fredy about it he YELLED AT MY WIFE and basic said not to question him. It seemed Fredy didn't want to do the extra work to look into it. He ended up adding it after I had another conversation with him. It's not over.. Once we finally get the plans and turn them into the City for review they get sent back to us. FREDY MESSED UP NORTH AND SOUTH! It then took him over 2 weeks to correct it! THIS COST US OVER 10K DOLLARS because the project was held up and we had to keep paying the mortgage FREDY MESSED UP OUR PLANS 2 MORE TIMES AND COST US OVER 20K DOLLARS IN MORTGAGE PAYMENTS AND MONTHS OF IDLE TIME Please don't be fooled by the 5 star reviews.

There was continuous and steady progress, and I usually was invited over each week to check on the progress of work. The project was well timed. The initial estimate was for around 5 months. It ended up taking 5 months and 3 weeks. The small delay was due to city permitting back-and-forth and weather, which all seemed understandable. The cost estimate was also quite accurate. We only went less-than-10% over, and generally due to things that we decided to upgrade partway through, or issues we discovered only after tearing open the walls. They also had a one year warranty on issues with the work, which they have honored with no hassle. Ultimately the company acts with integrity, and in this industry that's saying a lot.
