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.

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 felt it was important to share our experience with JZ structural as I ultimately went with them…read moregiven their high Yelp reviews. However, my experience was negative to say the least. Ellen was responsive initially, but this was only until they received payment. After this, trying to get a response was like getting blood from a stone: close to impossible. My architect had asked Julian, the engineer, if he could draw a rough mock up before he put together a full set of plans (to which he agreed). We never got this, despite checking in multiple times, and instead, it was only right upon the 'deadline' we had provided for the project that we received a full final set of plans. This was disappointing. The plans themselves were riddled with errors: it seemed like a lot of copy / paste work rather than careful attention to detail. The wrong county was listed, and certain structural details were copy pasted from the wrong city, which my architect had to point out. We had around 30 local contractors look at the plans, as well as two peer reviews of the plans from other licensed structural engineers, and the feedback was that it had been over-designed (consistent with one of the other yelp reviews). After multiple emails attempting to get Julian (the engineer) on a call, he was incredibly defensive, and rude. It was at this point, I was appalled that he would speak to a client like this, so decided to cut ties with this company and use another structural engineer instead. If you are in absolutely no rush, and have no concerns about over-design: perhaps this company will work for you. But for our residential project, this was one of the worst experiences I have had with a "professional" service, and I want to warn others.

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.

They made a big project feel smooth and stress-free. Also, they completed a full 400 square foot addition to my house in just over two months.
