"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Working with Kyle Askarian and K&K Engineering was a great and hands-down the best decision we made for our project. If you are looking for a structural engineer who is incredibly meticulous, highly efficient, and easy to talk to, this is the one.Structural issues and calculations can easily delay a project, but [Engineer's Name] ensured everything went perfectly. Here is what stood out the most:"

"We have been working with Sam on our home project to take down a load bearing wall and we are pleased with his work. I liked that he enjoyed small projects and the city engineer approved the plans the first time they were submitted. He also has come by to inspect the work our contractor has performed and advised the corrections that needed to be made so our home would be structurally sound. I highly recommend."

"Working with Jonathan has been a dream. This is the first time I've ever needed and architect and engineering for a home project, and wasn't sure what to expect, but Jonathan was great. He was incredibly patient with the adjustments and revisions that came with the process and pointed out some ideas that I never would have thought of on my own. As a bonus, the plans sailed through the city plan check, getting approved the very next day with no comments. I strongly recommend DesignX."

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

Structural Engineering FAQs, answered by experts

Before requesting structural engineering services in Irvine, gather your original building plans, prior inspection reports, and HOA guidelines. Take dated, clear photos of all visible concerns, noting locations and measurements. Track when each issue started or worsened, and keep records of previous repairs. Include any soil or drainage reports, permit documentation, and details of past insurance claims related to structural issues for a comprehensive overview.

Helpful?

Completing structural engineering projects in Irvine enhances your home’s safety, comfort, and functionality. Seismic retrofitting and foundation upgrades address local earthquake risks and clay soil movement, while open floor plan modifications improve natural light and airflow—ideal for Irvine’s climate. These improvements also support modern home systems, boost energy efficiency, and increase property value, making your home more appealing in Irvine’s competitive real estate market.

Helpful?

In Irvine, structural engineering projects are tailored to meet both functional needs and design preferences. Engineers often use concealed steel supports for open layouts, maximize natural light with larger windows, and select materials that complement local architectural styles. These projects also support indoor-outdoor living trends and ensure compliance with California’s energy codes, blending safety, efficiency, and curb appeal for modern Irvine homes.

Helpful?

In Irvine, expanding cracks in slab foundations, uneven floors in tract homes, or doors sticking after seasonal rain can signal underlying soil movement due to local clay soils. Recurring moisture near baseboards or visible separation at ceiling joints are also warning signs. If these issues worsen or appear together, prompt structural inspection is recommended to prevent more extensive repairs.

Helpful?

In Irvine, structural engineering work can impact HVAC, plumbing, and electrical systems, especially when modifying load-bearing walls or foundation elements. Projects near utility lines or within planned communities often require careful coordination with other home systems. Reviewing your home’s layout and consulting local professionals helps identify potential impacts, and permit reviews in Orange County typically include checks for related system changes.
