my experience with this company was absolutely horrible!…read morefirst of all to survey a property isn't the cheapest investment so you'd expect the service to be half way descent. This company took several hours to respond back to me to schedule appointment, that alone should have been a red flag but I still gave them another opportunity. Appointment time frame was 7:00am-7:30am, when he hadn't arrived by 8:30am I called them to see if he was late, they gave me BS that he was at the county getting info on my property. Then stated he'd arrive by 12:30-1:30pm again DID NOT SHOW! (keep in mind they already had my $1,500.00 deposit) Basically this went on all day didn't show up until 4:30 pm and the man that showed up had no idea what he was there for instead wanted to chat about his kids instead of getting the job done! I contacted there office and told them to just have him leave my property. waiting 9 hours is ridiculous. save your money and time stay away from this company!! unprofessional and unreliable, how people run there business like this is insane!

I can't say enough good things about Emad. From start to finish, he went above and beyond to help…read moreus navigate the soils engineering process and, most importantly, get approvals through the City of San Bernardino. Emad was extremely knowledgeable, responsive, and patient in explaining what was needed at every step. When challenges came up with the city, he didn't just hand off the problem--he actively worked with the reviewers, followed up consistently, and made sure nothing fell through the cracks. That level of dedication is rare. If you're looking for a soils engineer who truly advocates for their clients and understands how to work with local jurisdictions, Emad is the one. His professionalism and commitment saved us time, stress, and unnecessary delays. Highly recommend without hesitation.

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 contacted Mastercraft to install multiple sets of French doors to convert my garage into a bright…read moreopen studio space. Front start to finish, Mike Gast and Juan Navarro worked with me to translate my vision into the bright open studio I have been dreaming of... As the project manager, Mike Gast was extremely patient and accommodating, and provided lots of feedback to solve various issues. This was a large project that involved removing the garage door, retrofitting 3 sets of doors, framing and finishing for a custom look, inside and out. They even installed special thresholds so we could be assured of being able to roll equipment in and out of the space easily. After each stage of the job, the crew cleaned up the area and removed all debris. The price quoted us initially was in line with competitors, better than several, who failed to follow up with us. There was no cost-creep, and we finished at the price quoted us. Progress and payment was tracked on their online job project site, which was an added benefit and inspired confidence. I can highly recommend Mastercraft and hope to use them in the near future for several other home improvement projects. (A special thanks to the team, Victor and Tony for their cleanliness and work ethic).

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.
