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 am very disappointed with the level of service provided. The week prior, we had a detailed…read moreconversation regarding a resolution for an existing structure on our 5-acre property, and the engineer agreed to schedule an in-person consultation. 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, they were professional, respectful, and truly dedicated to delivering quality work. The crew showed up consistently -- they even worked on July 4th -- which really showed their commitment to staying on schedule and doing things right. The workmanship is flawless. Every detail looks clean and intentional, and the finished space blends perfectly with the rest of the house. To be honest, the quote was so good to begin with I thought it may have been too good to be true but it wasn't. I had a good handful of modifications throughout the project and Fawaz didn't charge me an extra dime. Everyone I interacted with was friendly, honest, and easy to communicate with. It's rare to find a team that does excellent work and is this pleasant to work with. I would absolutely hire them again and highly recommend them to anyone considering a remodel or addition. 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.
