"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 am a homeowner who did my own home remodeling architectural design. Even though I had architect degree, but I had never done any project in Los Angeles. As everybody knows, Building and Safety has tons of regulations to follow, which made the permitting process especially difficult. I was so lucky to work with David, my structural engineer, who is very sharp, knowledgeable and hardworking. Not only did he deliver his structural design on time but also he guided me through with all details of my architectural plan. He is very responsive and generous about sharing his knowledge. It was such a surprise when David got me the permit over the counter from the city office with only one attempt, which expedited my remodeling project timeline for at least two months. Definitely recommended!!"

"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."

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

"If you?re here looking for an architect, look no further. Francisco is the man for the job. He helped us with a garage to ADU conversion. Francisco kept us informed and communicated with us throughout the entire project. He was very professional, helpful and patient. We had tons of questions and he had the answers. He is very efficient and great at his job. We would hire him again with no hesitation. Thank you Francisco for making for making this process a breeze!"

"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

Structural Engineering questions, answered by experts

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

Any issue that affects the structural integrity or soundness of a home is considered a structural issue. In addition to foundation cracks, other signs of structural issues include roof leaks, bowing walls, sloping floors, gaps around windows and doors, and more.

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.
