"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!!"

"The project went great. Peter is very professional, super knowledgeable, responsive and timely. The plans were done on time and there were no problems with the city review. They answered the questions the contractor had during the construction. Couldn't be happier with the whole process. I thought it would be more difficult than it was. Thanks to Peter and his team we feel very safe with the new addition. We are planning on putting a second story on our house (when we can afford it) and we will absolutely use Peter.

"I've had the recent good fortune to work with Tolga on renovation projects in Los Angeles and Manhattan Beach for which I am the Architect. The success of renovation work relies heavily on collaborative and creative structural engineering in order to realize interior and exterior architecture goals. Tolga instinctively understood my design goals and in a very professional manner he crafted solutions to bring them to reality. Many thanks Tolga. I look forward to our next collaboration."

"I hired Kyle as my structural engineer for my ADU. Long story short, my original architect ghosted me, and left an incomplete plan and about two months before application expires. I had to change my design a bit and Kyle was so kind. He helped me finished my revision over a weekend even though he had a lot of work at hand after he leaned my situation. And the city revision only cost him a day. With his help I was able to pull my permit two days before the deadline! Excellent work Kyle! Much appreciated!"

"I was referred to 800 Remodeling by Angie's List, and the owner, Amir, called me literally minutes after I received the referral. I described my situation to him and we scheduled a meeting at my home for the following day. He arrived promptly and immediately introduced himself with a picture ID and his state contractor's license. After inspecting the cracks that were of concern to me in a structural post supporting a major beam, he took some pictures and promised to get back to me with some recommendations. The next day, he called just as he had promised, told me that after talking with a structural specialist he did not believe the post needed to be replaced, but nevertheless gave me a rough-order-of-magnitude estimate on what a replacement would cost, should I decide to have that done. After some additional research, I concluded that the cracks are typical and not impairing the structural integrity of the post, and decided for added insurance simply to reinforce the post with some wrap-around steel bands. Since that is a small and simple job, Amir offered to refer me to someone else to do that job for me. He did not charge me for the consultation or the time he spent in discussions with other specialists. So although I ultimately didn't hire him for this job, I was impressed by his professionalism and shall definitely be contacting him again for some larger jobs I am planning in the future."

"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 questions, answered by experts

If your home's foundation was damaged due to shifting soil, the same problem will reoccur unless you stabilize the structure by adding posts in the bedrock.

Yes, walls on the top floor can be load-bearing if stacked on the floor’s foundation.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.
