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.

We had a great experience working with Ramy on our ADU project. From the very first interaction, he…read morewas extremely responsive and professional. When he came out to take measurements, he offered smart suggestions that made our project more cost-effective while also adding long-term value to our home. Ramy delivered the plans ahead of schedule and took the time to walk us through everything in person. The city of Claremont's permit requirements are very strict, and it was clear that Ramy knew what the city would require. When the city had requests we didn't agree with, he communicated directly with the city planner on our behalf and guided us through the process with confidence and clarity. You get what you pay for with Ramy--his work is high quality, detailed, and thoughtful. His expertise, responsiveness, and professionalism made a stressful process feel smooth and manageable. We highly recommend him for any home or ADU project. He is absolutely worth it.

I am very disappointed with the level of service provided.

We confirmed an appointment from 12:00 PM to 1:00 PM in the Temescal area of Corona. Despite his office being located in Corona, he stated he was unable to find the property, even after I provided clear directions. My elderly parents were present at the property to assist, and I had arranged to meet him during my lunch break from work. Upon arrival, I found no issues accessing the property there were no "large rocks" blocking the entrance as he claimed. Unfortunately, he had already left before the scheduled time without proper communication. Instead, he states that we send photos of the structure. This experience was a significant waste of time and demonstrated a lack of professionalism, reliability, and respect for our schedule. I would not recommend this service based on our experience.

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.

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.
