Keystone Structural Engineers - Gold River, California

BYSON C.

One of the best structural and engineering company in the greater Sacramento area. We have worked multiple projects which implemented their designs, and we are very satisfied with the professionalism and quality of work they provide. Mr. Mehdi is very knowledgeable when it comes to tackling challenges and finding reasonable solutions. Recently we finished a multifamily project over in downtown Sacramento that showcases their great skills.

In my capacity as an architect for numerous residential projects, I have found the Keystone team to be exceptional in their provision of clear, timely responses and precise information. Their extensive familiarity with nearly all jurisdictions in California significantly simplifies the process of obtaining structural design and engineering services

Keystone Structural Engineers helped me solve a residential property issue that had been on my mind for quite a while. They were very professional and their pricing was also reasonable for the level of service they provide. I'd highly recommend them if you have this type of need, and are in the greater Sacramento Area.

I’ve had the pleasure of working with Keystone Structural Engineers on several projects, and I highly recommend them. As a designer, I appreciated their collaborative approach and keen attention to detail. The team is knowledgeable and quick to spot potential challenges, helping us avoid delays.

Their communication was clear and consistent, keeping everyone on the same page. They’re skilled at balancing technical needs with design goals, finding creative solutions that enhance both. Working with Keystone Structural Engineers was a smooth and enjoyable experience, and I look forward to working with them again.

Initially, Keystone Structural Engineers seemed professional and helpful, but my experience quickly went downhill. They delivered my as-built drawings late, and while mostly accurate, there were some errors and oversights. The engineered drawings arrived even later and were vague, with significant issues such as incorrect references (e.g., specifying a continuous footing instead of a pad footing).

When I requested changes to fix these errors, it took months to get a response, and when revisions finally arrived, they failed to address the problems. This cycle of delays and inadequate corrections repeated multiple times. Now, more changes are needed due to incorrect as-built drawings, and Keystone is refusing to complete the contracted work.

Throughout the entire process, communication has been slow, causing significant delays. To make matters worse, they have attempted to charge me more for fixing their own mistakes, which has been incredibly frustrating.

Overall, I’ve had an awful experience with this firm. It seems like residential projects aren’t a priority for them. If you’re looking for an engineering firm for your home, I would strongly recommend keeping your distance.

We have been working with keystone structural engineers for 2 years now. They do great work, Mehdi is knowledgeable and knows his stuff. The process to get your plans is usually 30 days and once you have them it’s smooth sailing. First try approvals with building departments every time.

I’ve also referred Mehdi to big commercial contractors building complicated structures and they all thank me for the fantastic referral. A+

I am halfway through my project, and so far, so good. Mehdi came out to my house, and patiently listened to all my insane ideas for a pool remodel. We went over each detail of my project, and reached an agreement on plans that I needed. His attention to detail has helped me coordinate the structural footings to work with all the plumbing and electrical elements of the project. Now, on to the second half.

I am so glad i found Keystone Structural Engineers. I was looking for a reliable and professional structural engineer to draw the plan for the removal of a load bearing wall in our house. The project was very complex and the load bearing wall was a 2-story load bearing wall that was also holding the weight of the room. Mehdi was amazing. He was very patient and provided the designs within the timeframe promised at a reasonable price. He even made himself available to answer any follow up questions from the City of Sacramento and helped with the permit process. He was available to even connect with my contractors and answer their questions. Truly appreciated it. Highly recommend Keystone Structural for any design work if you want professional and someone you can trust. Cannnot thank Mehdi enough.
